How Much Does It Cost to Dry Grain in Canada?

There is no single Canadian price for drying grain.

The cost can be only a few cents per bushel when removing a small amount of moisture with an efficient natural-gas dryer, or it can rise dramatically when using propane, drying very wet grain or processing crops that require much more water removal.

The mistake is asking:

How much does a grain dryer cost to run per hour?

A better question is:

How much does it cost to bring one bushel of my crop from its actual harvest moisture to my target moisture?

That cost depends on:

crop
incoming moisture
target moisture
dryer efficiency
natural gas or propane price
electricity
dryer capacity
labour
maintenance
annual bushels dried
depreciation and financing
whether grain is cooled inside the dryer or in the bin

For most farms, fuel is the largest variable drying expense, but fuel is not the entire cost.

This guide explains how to calculate grain drying cost in Canada and how to compare dryers without being misled by brochure BPH numbers or fuel prices quoted in different units.

What Does Grain Drying Actually Cost?

Grain drying cost can be divided into three levels.

Fuel-only cost

This includes only the propane or natural gas consumed by the burner.

It is useful for comparing fuels and dryer efficiency.

It is not the true cost of operating the dryer.

Operating cost

This normally includes:

fuel
electricity
labour
routine maintenance
normal wear parts

This is a much better number for comparing your own dryer with custom drying.

Full ownership cost

This includes operating cost plus the cost of owning the drying system.

That can include:

depreciation
financing or interest
opportunity cost of capital
insurance
major repairs
annualized installation cost
natural gas connection
propane storage
electrical upgrades
concrete
wet holding
dry-grain handling

A dryer can look inexpensive when only fuel is counted and expensive when the entire system is included.

Both numbers are useful.

Just do not confuse them.

Quick Grain Drying Cost Formula

A simple starting point is:

Drying cost per bushel = Total drying costs ÷ Bushels dried

For example, if the farm spends:

$12,000 on fuel
$2,000 on electricity
$1,500 on labour
$2,500 on maintenance

Total seasonal operating cost is:

$18,000

If 100,000 bushels were dried:

$18,000 ÷ 100,000 = $0.18/bu

That is the operating cost.

If the dryer and supporting infrastructure also represent another $12,000 per year in annualized ownership cost:

$30,000 ÷ 100,000 = $0.30/bu

Now you have a much better estimate of the true cost.

These numbers are only an example.

Your farm could be very different.

Why Cost per Bushel Can Be Misleading

Suppose Farm A dries wheat from 16% to 14%.

Farm B dries wheat from 20% to 14%.

Both report drying cost as:

$0.20/bu

Those are not equivalent drying operations.

Farm A removed two moisture points.

Farm B removed six.

This is why another useful metric is:

Cost per bushel per point of moisture removed

The formula is:

Total drying cost ÷ bushels ÷ moisture points removed

If drying costs $0.24 per bushel while removing four points:

$0.24 ÷ 4 = $0.06/bu/point

That makes it easier to compare different seasons and different dryers.

Moisture Points Are Not All Equal Physically

The per-point calculation is useful for farm management, but technically, each percentage point does not represent exactly the same amount of water.

Grain moisture is expressed as a percentage of total wet weight.

Because the dry matter stays while water leaves, the amount of physical weight removed changes as the grain becomes drier.

For most farm budgeting, cost per bushel per point is still a convenient benchmark.

For precise calculations, use actual water removal.

The Aglist Grain Dryer Sizing Calculator handles this for you.

Grain Shrinks When You Dry It

Drying removes water.

That means the grain weighs less afterward.

This is not mechanical grain loss.

It is the physical weight of water that left the crop.

The Canadian moisture shrink formula is:

Moisture shrink % = (Initial moisture – Final moisture) ÷ (100 – Final moisture) × 100

For example, drying grain from:

18% to 14%

produces moisture shrink of approximately:

4.65%

So 100 tonnes of grain at 18% moisture would contain approximately 95.35 tonnes after being dried to 14%, before considering any other physical handling losses.

The Canadian Grain Commission provides its own weight-loss-due-to-drying calculator using this principle.

Moisture Shrink Examples

Drying job	Approx. physical moisture shrink
18% → 14%	4.65%
15% → 10%	5.56%
12.5% → 8%	4.89%
20% → 14%	6.98%
25% → 15%	11.76%

This is why overdrying has a real financial cost.

If your grain only needs to reach 14% and you unnecessarily dry it to 12%, you burn more fuel and remove additional saleable weight.

The Biggest Cost Driver: Moisture Removal

The wetter the grain, the more expensive drying becomes.

Removing two points may be a relatively small job.

Removing ten points is a completely different energy requirement.

This affects both:

fuel cost
dryer capacity

The same machine moves fewer bushels per hour when it has to remove more moisture.

That means high-moisture grain can cost more in two ways.

You burn more fuel per bushel, and the dryer processes fewer bushels per hour.

Dryer Brochure Capacity Can Be Misleading

A dryer advertised at:

1,000 BPH

does not necessarily dry 1,000 bushels per hour under every condition.

Capacity depends on:

crop
incoming moisture
target moisture
air temperature
drying mode
ambient conditions

PAMI testing has historically standardized dryer capacity because meaningful comparisons require the same drying conditions.

Without standardized moisture removal, BPH numbers can be misleading.

Before comparing two dryers, make sure their capacity ratings refer to similar conditions.

Full Heat vs Dry & Cool Changes Cost and Capacity

Many continuous-flow dryers can operate in different modes.

Full Heat / All Heat

The entire dryer is used primarily for moisture removal.

Hot grain leaves the dryer and is cooled later in an aerated bin.

Advantages can include:

higher BPH
better use of dryer capacity

But the farm needs:

adequate aeration
suitable storage
good grain management

Dry & Cool

Part of the dryer is used for cooling before grain exits.

The grain enters storage cooler, but the section used for cooling is no longer available for maximum moisture removal.

Capacity therefore falls.

This is why the same dryer can have very different BPH ratings depending on mode.

When calculating cost, compare the complete system, not just burner fuel.

Natural Gas vs Propane Cost

Fuel choice can have a major effect on operating cost.

Natural Resources Canada lists approximate energy content of:

natural gas: 37.5 MJ/m³
propane: 25.3 MJ/L
electricity: 3.6 MJ/kWh

That allows both fuels to be converted to a common energy cost.

Natural gas cost per GJ

If your delivered variable gas price is in dollars per cubic metre:

$/GJ = $/m³ × 26.67

Propane cost per GJ

If propane is priced per litre:

$/GJ = $/L × 39.53

Now the two fuels can be compared properly.

For a deeper explanation, see Natural Gas vs Propane Grain Dryers.

Example: Comparing Fuel Prices

Suppose this is purely hypothetical:

Natural gas:

$0.25/m³

Propane:

$0.80/L

Natural gas energy cost:

$0.25 × 26.67 = $6.67/GJ

Propane energy cost:

$0.80 × 39.53 = $31.62/GJ

That does not mean propane will always cost 4.7 times as much to dry grain.

Dryer configuration and efficiency still matter.

But it shows why comparing $0.25/m³ with $0.80/L directly tells you very little.

Convert them to the same energy unit first.

Use the Delivered Variable Cost

For natural gas, do not look only at the commodity rate.

The bill may contain:

commodity cost
variable delivery charge
fixed monthly charge
taxes and other applicable charges

If natural gas is already connected to the farm, the most useful drying comparison is usually the incremental variable cost of consuming more gas.

Fixed charges exist whether the dryer runs or not.

If you are deciding whether to install a new natural gas service specifically for the dryer, then fixed service and connection costs belong in the investment analysis too.

SaskEnergy Has a Grain Drying Estimator

SaskEnergy provides a dedicated grain-drying energy estimator that allows farmers to enter:

bushels
crop
current moisture
target moisture
energy costs
installation costs

It then estimates energy cost per bushel and total annual energy expense for natural gas and propane.

The important point is not one specific result from the calculator.

The result changes dramatically with your inputs.

That is exactly why generic statements such as “grain drying costs 20 cents per bushel” should be treated cautiously.

Fuel Cost Is Usually the Largest Variable Expense

Fans and augers use electricity.

Employees or owners spend time operating and monitoring the system.

Parts wear.

But the burner usually consumes the largest amount of energy.

This makes fuel selection and dryer efficiency important when drying large annual volumes.

A difference of only a few cents per bushel becomes meaningful at scale.

For example:

25,000 bushels

5¢ difference:

$1,250

100,000 bushels

5¢ difference:

$5,000

300,000 bushels

5¢ difference:

$15,000

500,000 bushels

5¢ difference:

$25,000

Small differences matter when volume becomes large.

Electricity Cost

Electricity powers equipment such as:

fans
augers
metering systems
conveyors
control systems
grain legs

Large dryers can have substantial electric motor loads.

For example, a dryer may use multiple 15, 20 or 30 hp fan motors plus loading and unloading equipment.

The dryer itself is not always the entire electrical load either.

A grain site may simultaneously operate:

wet-bin auger
dryer fans
dryer augers
grain leg
takeaway conveyor
aeration fans

When evaluating operating cost, calculate the system rather than just the dryer nameplate.

Estimating Electricity Cost

A simplified method is:

kW × operating hours × electricity rate = electricity cost

A motor rated at 15 kW running for 100 hours at an illustrative electricity price of $0.15/kWh would use:

15 × 100 = 1,500 kWh

Cost:

1,500 × $0.15 = $225

Real motor load varies, and motors do not necessarily operate at full rated power continuously.

For accurate planning, use actual measured demand or electrician/manufacturer estimates.

Labour Cost

Labour is frequently ignored because the farm owner is doing the work.

That does not make the labour free.

Dryer labour can include:

loading
monitoring
moisture testing
switching bins
cleaning screens
checking burners
changing settings
unloading
maintenance
nighttime supervision

A highly automated continuous-flow system may reduce labour per bushel compared with an older manual batch dryer.

If labour availability is already a harvest bottleneck, automation can have meaningful economic value even if fuel consumption is similar.

Maintenance Cost

Maintenance varies enormously with dryer age and design.

Typical expenses may include:

bearings
belts
chains
auger flighting
motors
ignitors
flame sensors
temperature sensors
moisture sensors
contactors
controllers
screens
fan components

Older dryers may have low depreciation but higher repair requirements.

Newer dryers may have fewer mechanical repairs but expensive electronic components.

A sensible farm budget should include a maintenance reserve rather than treating every repair as an unexpected event.

Drying Cost for Wheat

Prairie wheat often requires relatively modest moisture removal compared with corn.

For example:

18% → 14%

means four moisture points.

The cost depends heavily on:

fuel
dryer efficiency
ambient temperature
BPH
whether cooling happens in the dryer

If natural gas is available at an economical delivered rate, fuel-only cost can remain relatively low.

Propane raises the fuel component, particularly in a wet year.

But the important comparison is not wheat versus another crop alone.

It is the exact amount of water that needs to be removed.

Drying Cost for Canola

Canola creates different challenges.

The crop may require:

lower drying temperatures
careful moisture control
lower throughput
additional screen cleaning

For long-term storage, farmers commonly target moisture below the official straight-grade threshold.

That means the dryer may need to remove several moisture points even when canola is only moderately tough.

Read How to Dry Canola Safely for moisture and temperature guidance.

A canola drying job such as:

12.5% → 8%

removes 4.5 moisture points and results in approximately 4.9% physical moisture shrink.

That lost weight needs to be understood separately from fuel cost.

Drying Cost for Corn

Corn is where grain drying economics become especially significant.

Corn may come off the field at:

20%
25%
30% moisture

while the storage target may be around the mid-teens depending on the intended storage system.

Removing ten or more moisture points requires substantial energy.

The dryer also processes fewer bushels per hour as moisture removal increases.

This is why high-capacity corn operations often invest heavily in:

efficient continuous-flow dryers
natural gas infrastructure
heat recovery
large wet holding capacity

A fuel decision that barely matters for occasional Prairie wheat drying can become one of the largest operating decisions on a corn operation.

Drying Cost for Barley

Barley may have another constraint.

If grain is intended for malting or seed, excessive drying temperature can affect germination.

That can force the farm to dry more slowly and conservatively.

Government of Saskatchewan guidance emphasizes low-temperature drying when heat is required for malting barley.

So the cheapest way to remove water is not necessarily the most profitable method.

Maintaining crop quality matters.

Drying Cost for Seed Grain

Seed grain often requires lower temperatures than commercial grain.

Lower temperatures can mean:

slower drying
reduced throughput
longer dryer runtime

That can increase cost per bushel.

But preserving germination is worth far more than maximizing BPH.

When drying seed:

quality cost matters more than fuel cost alone.

Crop Quality Can Be More Valuable Than Fuel Savings

The Canadian Grain Commission publishes maximum drying-air temperature guidance for different crops and intended uses.

Excessive heat can damage:

germination
malting quality
oil quality
grain quality

Saving two cents per bushel by running excessively hot is not a saving if crop value falls.

The correct drying cost calculation includes product quality.

Natural-Air Drying Can Be Cheaper

Not every bushel needs a high-temperature dryer.

Natural-air drying can be economical when:

grain is only slightly tough
weather conditions have drying capacity
airflow is adequate
grain depth is manageable
time is available

The main operating expense is electricity for fans, with supplemental heat added when necessary.

Government of Saskatchewan and PAMI both provide extensive guidance on natural-air grain drying.

Natural-air systems can be especially attractive when grain is only a few points above dry.

Natural Air Is Not Always the Cheapest Choice

A low hourly operating cost does not help if grain spoils before the drying front moves through the bin.

Natural-air drying depends on:

airflow
grain depth
weather
relative humidity
temperature
crop

Canola Council research notes that supplemental natural-air drying may become unsuitable when starting moisture is more than roughly three points above dry unless grain depth or management is adjusted.

When grain is genuinely damp, a heated dryer can become the lower-risk economic choice.

Supplemental Heat Cost

Adding heat to a natural-air system can improve drying conditions.

PAMI provides the following relationship for estimating heater capacity:

BTU/hr = Temperature increase °C × airflow cfm × 2.05

For example, raising 5,000 cfm of air by 10°C requires roughly:

102,500 BTU/hr

before accounting for system inefficiency.

This illustrates an important point.

Even “a little supplemental heat” can consume a meaningful amount of fuel when large volumes of air are involved.

Dryer Efficiency Matters

Two dryers can remove the same amount of water while consuming different amounts of fuel.

Efficiency is influenced by:

dryer architecture
heat recovery
grain column depth
airflow
insulation
exhaust design
cooling strategy
control accuracy

A newer efficient dryer may cost more to purchase but use less fuel every season.

The bigger the annual volume, the more valuable that efficiency becomes.

How to Compare Dryer Efficiency

The best technical comparison is energy consumed per amount of water removed.

Common measures include:

BTU per pound of water removed
MJ per kilogram of water removed

This is much more meaningful than simply comparing:

litres of propane per hour

m³ of natural gas per hour

A larger dryer may burn twice as much fuel per hour while drying three times as much grain.

Its hourly fuel bill is higher, but its cost per bushel may be lower.

Do Not Compare Fuel Burn per Hour Alone

Imagine:

Dryer A

Fuel:

$100/hour

Capacity:

400 BPH

Fuel cost:

$0.25/bu

Dryer B

Fuel:

$180/hour

Capacity:

1,000 BPH

Fuel cost:

$0.18/bu

Dryer B looks more expensive if you only watch the fuel meter.

It is cheaper per bushel.

This is why BPH and fuel consumption always need to be considered together.

Dryer Capacity Also Affects Labour Cost

A dryer running 250 BPH requires four hours to process 1,000 bushels.

A dryer running 1,000 BPH requires one hour.

Even if fuel efficiency is identical, the slower machine may require more:

operator time
fan runtime
auger runtime
harvest coordination

This is another reason a larger dryer can sometimes reduce cost even when its hourly operating expense is higher.

But Bigger Is Not Automatically Cheaper

An oversized dryer carries its own cost.

You may pay for:

larger electrical service
larger gas connection
larger wet bin
larger conveyors
higher capital cost
unused capacity

A dryer that spends most of its life operating well below design capacity may not provide the best return.

Use the Grain Dryer Sizing Calculator to estimate capacity before comparing models.

Wet Holding Is Part of Drying Economics

Imagine your combine delivers:

1,200 BPH

while the dryer processes:

800 BPH

That does not necessarily mean the dryer is too small.

A wet bin can absorb the difference during harvest.

After the combine stops, the dryer continues running.

This can make a smaller dryer economically sensible.

But if wet storage fills every afternoon and the combine stops, the dryer has become a harvest bottleneck.

The value of a bigger dryer is then not only lower drying cost.

It can also be more combine uptime.

What Is One Hour of Harvest Worth?

This question is difficult but important.

If the combine and crew sit for two hours because the dryer cannot keep up, the cost is not just:

labour
diesel
machine depreciation

You may also lose part of a short weather window.

That is why drying systems should be evaluated as part of harvest capacity.

A dryer that costs slightly more per bushel but prevents combine shutdowns can still be the better investment.

Installation Cost Matters

The dryer itself may be only part of the investment.

A new installation can require:

concrete
electrical service
transformer
natural gas line
propane tanks
wet holding
load auger
takeaway conveyor
grain leg
aeration
automation
crane work
permits and inspection

When comparing drying cost, annualize these costs over the expected useful life of the system.

Example of Annualized Ownership Cost

Suppose a complete dryer project costs:

$200,000

This is only an illustration.

If you choose to allocate that investment over 20 years before considering financing or residual value:

$200,000 ÷ 20 = $10,000/year

If the farm dries:

25,000 bu/year

Capital allocation:

$0.40/bu

100,000 bu/year

Capital allocation:

$0.10/bu

250,000 bu/year

Capital allocation:

$0.04/bu

This shows why dryer economics are extremely sensitive to annual volume.

Low Annual Volume Can Make Used Equipment Attractive

If the farm dries only 20,000 bushels in a typical year, a large new drying project may have high fixed cost per bushel.

That is one reason used dryers remain popular across Western Canada.

A well-maintained used machine can reduce capital cost substantially.

But condition matters.

Read the Used Grain Dryer Buying Guide before evaluating older GSI, Super-B, GT or Vertec equipment.

High Annual Volume Rewards Efficiency

Now consider a farm drying:

300,000 bushels per year

A 5-cent-per-bushel efficiency improvement is worth:

$15,000 each season

Over ten seasons:

$150,000

That can justify:

newer dryer technology
natural gas connection
heat recovery
automation
higher-capacity grain handling

Large operations should spend much more time modelling energy use than small occasional dryers.

Used Dryer vs New Dryer Economics

A used dryer generally has:

Lower fixed cost

Less depreciation and less capital tied up.

Potentially higher variable cost

Older technology may consume more energy and require more repairs.

A new dryer generally reverses that relationship.

The correct comparison is:

Annual fixed cost + annual variable cost

not simply purchase price.

Custom Drying vs Owning a Dryer

Some farms have access to commercial or custom grain drying.

This eliminates much of the capital investment.

But it creates other costs:

custom drying charge
hauling
waiting
handling
scheduling risk

A simple break-even formula is:

Break-even bushels = Annual dryer fixed cost ÷ (Custom drying rate – Own variable drying cost)

Hypothetical Custom Drying Example

Assume:

Annual fixed dryer ownership cost:

$30,000

Custom drying:

$0.45/bu

Your own variable cost:

$0.15/bu

Difference:

$0.30/bu

Break-even:

$30,000 ÷ $0.30 = 100,000 bu/year

Above roughly 100,000 bushels in this example, ownership begins recovering the annual fixed cost.

Below it, custom drying could be competitive.

Again, these are hypothetical numbers.

Use actual local rates.

Grain Drying Cost and Moisture Discounts

Sometimes the real comparison is:

Dry the grain or sell it tough/damp?

That requires comparing:

drying cost
moisture shrink
elevator discount
transportation
crop quality risk
timing
storage needs

If the elevator discount is higher than your true drying cost, drying may add value.

If drying and shrink cost more than the discount, immediate delivery may be economically reasonable.

The answer changes with crop price and moisture.

Moisture Shrink Is Not a Dryer Fee

This distinction is important.

If you reduce grain moisture, part of the delivered weight disappears regardless of whether:

you dry it yourself
a commercial dryer dries it
the elevator dries it

That water was part of the original weight.

Do not blame the dryer for normal moisture shrink when comparing alternatives.

Instead compare:

unavoidable physical shrink
drying cost
additional handling loss
elevator deductions

Overdrying Is Expensive

Suppose your storage target is 14%.

You accidentally dry to 12.5%.

You have now:

burned extra fuel
reduced dryer capacity
removed more saleable weight

That is three economic penalties from one mistake.

Good moisture control can therefore produce a surprisingly quick return.

Automation Can Save Money

Modern moisture control can adjust discharge rate based on grain condition.

This can reduce:

overdrying
underdrying
manual adjustments
labour

Systems such as modern GSI and Super-B controls become increasingly valuable as annual dryer volume rises.

You can browse GSI grain dryers and Super-B grain dryers on Aglist for model-level specifications.

Grain Temperature Affects Economics Too

Higher drying temperature usually increases moisture-removal rate.

But more heat is not always better.

Excessive temperature can damage grain quality.

The Canadian Grain Commission provides different maximum drying-air guidelines depending on:

crop
seed use
malting use
commercial use
feed use

A profitable dryer setting protects quality while still maintaining acceptable capacity.

Saskatchewan Grain Drying Costs

Saskatchewan farms have an important potential advantage where natural gas service is available.

SaskEnergy offers a dedicated agricultural grain drying estimator and publishes separate commodity and delivery components for business natural gas accounts.

However, not every yard has sufficient gas service.

The economics may need to include:

gas-line extension
meter
regulator
trenching
licensed gas work

For farms without economical natural gas access, propane remains an important option.

Alberta Grain Drying Costs

Alberta conditions vary considerably by region.

Some areas may only occasionally require drying cereals, while others use drying more regularly for:

corn
canola
cereals

Natural gas availability again has a major effect on operating economics.

When drying demand is intermittent, the capital cost of permanent infrastructure deserves just as much attention as fuel price.

Manitoba Grain Drying Costs

Manitoba has more corn and soybean production than much of the western Prairies, which can make large moisture removal more common.

The province also publishes specific guidance for damp-grain drying and grain dryer installation.

Where corn is harvested well above storage moisture, drying can become a major annual production expense rather than an occasional harvest cost.

Ontario Grain Drying Costs

Corn drying is a major consideration in Ontario.

Large annual moisture removal makes:

dryer efficiency
natural gas supply
heat recovery
automation

particularly important.

A few cents per bushel in efficiency can represent substantial annual money on high-volume corn operations.

How to Calculate Your Own Grain Drying Cost

Use this process.

Step 1: Record wet bushels

How many bushels will actually pass through the dryer?

Do not use total farm production if only part of the crop is normally dried.

Step 2: Record incoming moisture

Use representative samples.

Step 3: Choose target moisture

Do not automatically dry lower than necessary.

Step 4: Calculate moisture removal

Example:

18% incoming

14% target

4 points removed

Step 5: Enter your fuel price

For propane, use actual delivered $/L.

For natural gas, use the applicable variable delivered rate.

Step 6: Estimate dryer energy consumption

Use:

manufacturer data
previous fuel bills
dealer estimates
measured operation

Step 7: Add electricity

Include the entire drying system where practical.

Step 8: Add labour

Even family labour has economic value.

Step 9: Add maintenance

Use several years of repair history if available.

Step 10: Add ownership cost

Include annualized capital cost if you want the full cost.

Step 11: Divide by bushels

Now you have a meaningful $/bu number.

Step 12: Divide by moisture points

This gives $/bu/point for easier comparisons between seasons.

Example Full-Cost Calculation

This example is deliberately hypothetical.

A farm dries:

100,000 bu

Seasonal expenses:

Fuel:

$12,000

Electricity:

$2,000

Labour:

$1,500

Maintenance:

$2,500

Variable operating cost:

$18,000

Operating cost per bushel:

$0.18/bu

Annualized dryer and infrastructure ownership:

$12,000

Total annual drying cost:

$30,000

Full cost:

$0.30/bu

If the average drying job removed four moisture points:

$0.30 ÷ 4 = $0.075/bu/point

That is the kind of number you can compare across years or against custom drying.

What Is a Good Drying Cost?

There is no universal target.

A good drying cost is one that:

protects grain quality
keeps harvest moving
is lower than the economic alternatives
fits your farm’s annual volume
does not require excessive capital for unused capacity

For one farm, $0.15/bu may be expensive.

For another farm drying very wet corn, $0.40/bu may be excellent.

The moisture removal has to be included in the comparison.

How to Reduce Grain Drying Cost

Avoid overdrying

This saves both fuel and grain weight.

Use natural gas where economically available

For high annual volume, the fuel-cost difference can become substantial.

Keep the dryer full

Many dryers operate inefficiently when repeatedly starting, stopping or running far below design conditions.

Maintain burners and fans

Poor combustion or airflow wastes energy.

Clean screens and air passages

Restricted airflow reduces drying performance.

Improve wet-grain logistics

Keep the dryer supplied rather than repeatedly stopping.

Cool in-bin when appropriate

All Heat operation can increase dryer throughput when the storage system can safely handle cooling.

Use automation

Accurate moisture control can reduce unnecessary drying.

Upgrade an inefficient dryer when the math supports it

On large annual volumes, energy savings can justify major equipment investment.

When a More Expensive Dryer Is Actually Cheaper

Suppose Dryer A costs $80,000 less.

But Dryer B saves:

$12,000 per season

in fuel, labour and repairs.

Ignoring financing and residual value:

$80,000 ÷ $12,000 = 6.7 seasons

After that point, the more expensive dryer may have the lower total cost of ownership.

This is why dryer purchases should be evaluated over years, not just at the dealer invoice.

When a Cheap Used Dryer Makes More Sense

The opposite can also be true.

If you only dry:

15,000 or 20,000 bushels

in a typical year, paying hundreds of thousands of dollars for the most efficient new dryer may never recover the additional capital.

A maintained older dryer may be economically superior even if it uses more fuel per bushel.

Annual volume decides which side of the equation matters more.

How the Aglist Calculator Helps

The Aglist Grain Dryer Sizing Calculator combines:

crop
wet bushels
incoming moisture
target moisture
available drying hours
fuel choice
fuel price

to estimate the dryer capacity required and expected operating cost.

Use it as a planning tool, then confirm final equipment sizing and fuel consumption with manufacturer data or a dryer specialist.

Final Thoughts

The cost to dry grain in Canada cannot be reduced to one number.

A useful drying budget needs to answer five questions:

How much grain are you drying?

How much moisture are you removing?

How much energy does your dryer use?

What does that energy cost?

What does owning the drying system cost each year?

Fuel may be the biggest variable expense, but it is only one part of the calculation.

Electricity matters.

Labour matters.

Maintenance matters.

Capital cost matters.

Moisture shrink matters.

And the cost of stopping harvest because the dryer cannot keep up can matter even more.

The best way to compare systems is therefore to track:

$/bushel

and

$/bushel/moisture point

while keeping physical moisture shrink separate from dryer operating expenses.

If your annual drying volume is small, low capital cost may be more important than maximum fuel efficiency.

If you dry hundreds of thousands of bushels, a few cents per bushel in fuel or efficiency can justify major infrastructure investment.

Start with your actual crop, moisture and fuel prices.

Then calculate the cost for your farm rather than relying on a generic Canadian average.

Use the Aglist Grain Dryer Sizing Calculator to run your own numbers.

Frequently Asked Questions

How much does it cost to dry grain per bushel in Canada?

There is no single national cost. Fuel-only cost can range from a few cents per bushel for modest moisture removal using low-cost natural gas to much higher amounts for propane or very wet grain. Calculate cost using your crop, moisture removal, dryer efficiency and local fuel rate.

How do I calculate grain drying cost per bushel?

Add fuel, electricity, labour and maintenance costs, then divide the total by bushels dried. Add annualized ownership costs if you want the full cost of drying.

What is cost per bushel per point?

Divide your drying cost per bushel by the number of moisture percentage points removed. It is useful for comparing different drying seasons.

Is natural gas cheaper than propane for grain drying?

Natural gas is often less expensive per unit of energy where suitable service is available. Connection cost can change the long-term economics, especially on farms with low annual drying volume.

How do I compare propane and natural gas prices?

Convert them to dollars per gigajoule. Approximate energy contents are 37.5 MJ/m³ for natural gas and 25.3 MJ/L for propane.

Does grain lose weight when it is dried?

Yes. Drying removes water, so the physical weight declines. This normal moisture shrink is separate from mechanical handling loss.

How much weight is lost drying grain from 18% to 14%?

Using the Canadian moisture-shrink formula, the physical moisture shrink is approximately 4.65%.

Does overdrying grain cost money?

Yes. Overdrying consumes additional fuel, lowers dryer throughput and removes extra saleable water weight.

What is the biggest grain drying expense?

Fuel is usually the largest variable operating expense in heated-air drying, although capital cost can dominate the full cost per bushel on farms with low annual dryer utilization.

Is electricity a major grain drying cost?

It can be meaningful, particularly on larger systems with multiple fan motors, grain legs, conveyors and aeration fans. It is generally smaller than burner fuel but should still be included.

Is natural-air drying cheaper than a grain dryer?

It can be when grain is only slightly above target moisture and weather and airflow are favourable. It can become risky or ineffective with very damp grain, deep bins or poor drying weather.

Is it cheaper to use All Heat or Dry & Cool?

All Heat can increase dryer throughput by using more of the dryer for moisture removal, but the grain must then be cooled safely in storage. The better option depends on the entire drying and storage system.

Does a larger dryer cost more per bushel?

Not necessarily. A larger dryer can have higher hourly fuel use while producing lower cost per bushel because it processes more grain. Oversizing can still increase ownership cost.

Is a used grain dryer cheaper to operate?

Not always. Used dryers generally have lower capital cost but may use more fuel or require more repairs. Compare total annual fixed and variable costs.

When does owning a grain dryer make sense compared with custom drying?

Compare annual fixed ownership cost with the difference between custom drying rates and your own variable cost. Annual bushel volume has a major effect on the result.

How much does it cost to dry canola?

The cost depends on incoming moisture, target moisture, fuel and dryer efficiency. Canola also requires careful temperature management, which can reduce throughput compared with higher-temperature drying.

How much does it cost to dry corn?

Corn can be expensive to dry because it is often harvested many moisture points above safe storage levels. Large moisture removal increases both energy consumption and drying time.

Does grain dryer efficiency matter?

Yes. On large annual volumes, relatively small improvements in fuel use per bushel can produce substantial seasonal savings.

How can I estimate my own drying cost?

Use your real bushels, moisture levels, local fuel price and drying hours in the Aglist Grain Dryer Sizing Calculator, then add labour, maintenance and annual ownership cost if you want a full-cost estimate.
