GSI 2322 & 2322X Portable Grain Dryer

The GSI 2322 is a two-module portable grain dryer in the 2300 Series, built around three vane axial fans (one upper, two lower), three heaters, and a three-stage drying architecture. With 1,149 bushels of holding capacity and Full Heat drying performance up to 2,200 BPH at 5-point moisture removal, the 2322 delivers a meaningful capacity step up from the 2,010 BPH 2320 while remaining one model below the flagship 2326.

The 2322 occupies a balanced position in the 2300 Series lineup. Below it, the 2320 represents the cost-effective entry into 2,000+ BPH territory. Above it, the 2326 jumps to 2,700 BPH with substantially larger fans, heaters, and capital cost. The 2322 fits directly between these two — capacity above 2,000 BPH at moderate increases in size and electrical load over the 2320, but well below the infrastructure demands of the 2326 flagship.

For operations handling 8,000 to 11,000 acres of corn — or any grain operation needing reliable Full Heat throughput in the 2,000–2,300 BPH range with optional uniformity optimization — the 2322 frequently represents the optimal balance between capacity, capital cost, and quality flexibility.

2322 vs 2322X — Configuration Choice

The 2322 is offered in two configurations. Both share identical drying performance, fans, heaters, and grain column. The difference is the fan layout.

2322 — Standard Configuration

The standard 2322 uses GSI’s conventional three-fan layout for the 2300 Series — one fan and heater on the upper module, two fans and heaters on the lower module. This delivers the full 2,200 BPH Full Heat capacity at 5-point removal with standard heat distribution across the grain column.

Best for: Operations primarily running Continuous Dry & Cool or All Heat where grain uniformity isn’t a premium grading factor. General-purpose corn drying applications at the 2,000–2,300 BPH throughput level fit this profile.

2322X — X-Stream Variant

The 2322X is a 2322 with the X-Stream fan rearrangement applied. X-Stream redistributes airflow and heat across the grain column from front to back, producing measurably more uniform drying. Capacity numbers stay identical to the standard 2322 (2,200 BPH Full Heat at 5-point removal — actual rated Full Heat at 5-point in X-Stream tables is 2,195 BPH, effectively the same), but grain quality at that throughput improves — fewer overdried kernels at hot spots and fewer wet pockets at cooler areas in the column.

X-Stream is particularly valuable on the 2322 because the longer 22-foot grain column has more potential for front-to-back heat variation than shorter columns earlier in the series. The X-Stream layout effectively neutralizes that variation, which becomes increasingly important at the 2322’s high throughput level.

Best for: Food-grade corn producers, seed corn operations, malting barley growers (with small grain screen), and any operation where grain uniformity directly affects grading and price.

There’s no S/H distinction within the 2300 Series. The 2322X is simply the 2322 with X-Stream applied at order, and both configurations share the same structural specifications.

Drying Capacity

All capacities below are wet bushels per hour, based on mature unfrozen #2 yellow shelled dent corn. Full Heat assumes grain is cooled in-bin after discharge; Dry & Cool numbers reflect grain that exits the dryer already cooled. The 2322 and 2322X share effectively identical capacity ratings.

Mode	Moisture Removal	Capacity
Full Heat	30% to 15%	1,010 BPH
Full Heat	25% to 15%	1,360 BPH
Full Heat	20% to 15%	2,200 BPH
Dry & Cool	25% to 15%	930 BPH
Dry & Cool	20% to 15%	1,500 BPH

The 2322 hits 2,200 BPH in Full Heat at 5-point removal — about 9% more than the 2320 and a meaningful step closer to the 2326 flagship’s 2,700 BPH. The capacity gain over the 2320 is delivered by extending the grain column from 20′ to 22′, upgrading the top fan from 25 HP/42″ to 30 HP/42″, and stepping the top heater from 7.5 to 8.75 Mil. BTU/hr (about 17% more thermal output on the primary drying stage).

Notably, the 2322’s lower module fans and heaters remain identical to the 2320 (15 HP/36″ fans, 4.5 Mil. BTU/hr heaters). The capacity gain from 2320 to 2322 is delivered almost entirely through upper module improvements and column extension — the lower module is sized to handle the additional secondary drying load without further upgrade. This is an important engineering insight: the 2322 sits at the upper limit of what the standard lower module configuration can support before the 2326 requires a full lower module redesign.

In Dry & Cool mode, the 2322 delivers 1,500 BPH at 5-point removal — 9% more than the 2320 and the highest Dry & Cool capacity available in the 2300 Series below the 2326 flagship. For operations whose primary mode is continuous cooled-grain drying, the 2322 represents strong throughput at moderate capital cost.

Fan & Heater Configuration

The 2322 uses the standard 2300 Series 1+2 fan configuration: one fan and heater on the upper module, two fans and heaters on the lower module.

Upper module:

• 1 vane axial fan @ 30 HP, 42″
• 1 heater @ 8.75 Mil. BTU/hr

Lower module:

• 2 vane axial fans @ 15 HP, 36″
• 2 heaters @ 4.5 Mil. BTU/hr each

The 2322’s upper module represents a significant step up from the 2320: the top fan grows from 25 HP to 30 HP (+20% horsepower) and the top heater grows from 7.5 to 8.75 Mil. BTU/hr (+17% thermal output). The 30 HP top fan is the largest in the standard 2300 Series before stepping up to the 2326’s 40 HP top fan.

The lower module remains identical to the 2320 (15 HP/36″ fans, 4.5 Mil. BTU/hr heaters per heater). This lower module sizing is engineered to handle secondary drying and cooling for both the 2320 and 2322 throughput levels, making the lower module a shared platform across these two models.

In the 2322X X-Stream configuration, the fan layout is rearranged to optimize airflow distribution from front to back of the grain column. This produces more uniform drying across the depth of the dryer, particularly beneficial when running at peak Full Heat capacity where uneven heat exposure is most visible in final grain quality. On the 22-foot column, the uniformity advantage is more pronounced than on shorter columns earlier in the series.

The 2322 is three-phase only. Voltage options include 208V, 230V, 460V, and 575V:

• 208V three-phase: 199–275 amps
• 230V three-phase: 183–254 amps
• 460V three-phase: 99–132 amps
• 575V three-phase: 82–109 amps

Higher voltages deliver lower amp draw and are often preferred where 460V or 575V service is already in place. For operations without three-phase service, single-to-three-phase converters can be used — though for dryers in the 2322 class, this is rarely cost-effective compared to upgrading the farmstead’s electrical service.

Grain Column & Holding Capacity

The 2322 uses standard 14-inch wide grain columns measuring 22 feet long. Total holding capacity is 1,149 bushels, with 1,067 bushels held inside the active grain column itself across both modules. The remainder occupies the loading and discharge zones above and below the dryer body.

The 22-foot column length is identical to the 1222S/H in the 1200S&H Series, but because the 2322 stacks two modules, it holds nearly twice the grain at any given moment (1,149 BU vs 599 BU on the 1222). This is the practical impact of two-module architecture — doubled grain column surface area means doubled holding capacity at the same column length, which directly enables the dryer’s higher throughput.

The 14″ column width is GSI’s standard for the entire portable lineup and is optimized for corn-sized kernels. For drying canola or other small grains, the optional small grain screen with 0.055″ perforations is available. Note that installing the small grain screen reduces corn drying capacity by approximately 20%.

Loading, Unloading & Metering

Top auger (loading): 8-inch flight driven by a 7.5 HP motor, with a peak loading rate of 3,800 BPH. The 7.5 HP loader handles the 2322’s 22-foot column without extending fill time relative to the 2320, keeping truck cycle time short during high-throughput harvest operations.

Bottom auger (unloading): 8-inch flight in a 10-inch tube, also 7.5 HP. The unloading auger keeps pace with the dryer’s peak metering capacity.

Meter roll drive: 1 HP VFD with maximum metering capacity of 3,080 BPH — meaningful headroom over the 2322’s actual maximum throughput of 2,200 BPH Full Heat. This margin matters most in All Heat mode at peak capacity, where actual discharge rates can spike during high-throughput drying cycles.

The VFD-driven meter roll, combined with Vision Controls, lets the 2322 target a specific exit moisture content and adjust unload speed dynamically as inlet moisture varies. At the 2322’s throughput level, dynamic moisture targeting consistently reduces overdrying losses by 1–2% — which on 100,000+ bushels per harvest season translates to substantial dollar savings.

Operating Modes

The 2322 and 2322X support all four standard operating modes of the 2300 Series. The three-stage architecture makes Continuous Dry & Cool particularly efficient compared to two-stage single-module dryers.

All Heat — Maximum throughput. Grain leaves the dryer hot and is cooled in-bin. Best for corn and rice operations with adequate in-bin cooling air. Peak capacity: 2,200 BPH at 5-point removal. Important: at this throughput, in-bin cooling typically requires bins of 50,000 bushels or less for safe cooling without active grain management. Operations running the 2322 at peak All Heat capacity should size cooling bin infrastructure accordingly — particularly relevant at this dryer’s high throughput where multiple cooling bins may be needed in sequence.

Continuous Dry & Cool — Full continuous flow with integrated cooling. Grain exits cooled and ready for direct binning at up to 1,500 BPH. The 2322’s three-stage architecture and upgraded upper module make this mode particularly effective.

Staged Batch Dry & Cool — Alternating dry/cool cycles inside the dryer. Particularly useful for high-moisture corn or sensitive grains where extended exposure to heat affects quality.

Continuous Flow — Steady-state production mode for lower moisture differentials.

The 2322X X-Stream variant runs all four modes with the same capacity numbers but delivers measurably better grain uniformity at any given throughput — most visible in Continuous Dry & Cool and Staged Batch modes where dwell time variations within the column most affect final grain quality. On the 22-foot column, X-Stream’s uniformity advantage is more pronounced than on shorter columns in the series.

Transport & Installed Dimensions

The 2322 is engineered as a portable dryer despite the larger two-module stack. Operators planning to relocate the 2322 should confirm tractor or truck capacity is rated for portable grain handling equipment in the 22,000+ lb class.

Dimension	Transport	Installed
Length	31′ 2″ (hitch to discharge auger)	31′ 10″
Width	8′	8′ 8″
Height	13′ 5″ (11′ 9″ shortest)	25′ 11″ (excl. foundation supports)
Approximate Weight	22,500 lbs (less transport kit)	—

Transport height is given with both standard and shortest configurations — the lower 11′ 9″ figure assumes the discharge auger is folded down for road transport under low bridges and power lines.

The installed height of 25′ 11″ is fixed across all 2300 Series models — it represents the structural height of the two-module stack and doesn’t change with grain column length. This is significantly taller than any single-module dryer (the 1222 installed height is 14′ 6″) and is the most important physical consideration when planning a site for the 2322 versus a single-module alternative.

At 22,500 lbs transport weight (less transport kit), the 2322 is about 1,500 lbs heavier than the 2320 — primarily from the longer column and larger top fan and heater.

Vision Controls

The 2322 ships standard with Vision Controls — GSI’s purpose-built color touchscreen control system for grain dryers. Vision handles:

• All four operating modes with dedicated mode-select interface
• Plenum temperature setpoints for all three heaters independently (upper plenum, lower-front plenum, lower-rear plenum)
• Moisture-targeting through automatic meter roll VFD adjustment
• Full system diagnostics and fault logging
• Multi-grain profiles for fast switching between corn, soybeans, wheat, rice, and other crops

Independent control of all three plenums is one of the operational advantages of the 2300 Series over single-module dryers. The operator can fine-tune upper plenum temperature for primary moisture removal (where the 2322’s larger 8.75 Mil. BTU/hr heater operates) while adjusting lower plenums for cooling intensity — a level of granular control that two-stage single-module dryers cannot offer.

The Vision display can be mounted directly on the dryer or remoted into a shop or office with a hardwired connection. The remote option is particularly useful for two-module dryers because the operator typically cannot see the upper plenum directly from ground level during operation.

GSI Connect Remote Management

The 2322 is GSI Connect compatible, enabling phone-based remote monitoring and control through the GSI Connect mobile app. Connect functionality includes:

• Real-time dryer status (running, idle, fault)
• Live plenum temperatures for all three heaters and grain moisture readings
• Remote setpoint adjustment for each heater independently
• Remote stop function
• Unload speed adjustment
• Performance logs and runtime alerts

GSI Connect is especially valuable on the 2322 because three-fan, three-heater dryers benefit substantially from continuous monitoring — minor variations in any of the three plenum temperatures can affect grain quality, and Connect surfaces these issues immediately rather than at the next physical inspection.

For overnight harvest operations — common at the 2322’s throughput level — Connect’s remote monitoring capabilities let the operator catch faults and verify performance without physical trips to the dryer. Historical performance data captured through Connect can also be used to optimize drying efficiency season over season — particularly valuable on a unit handling 100,000+ bushels per harvest season where small efficiency gains translate to meaningful fuel savings.

Optional Equipment

Beyond the standard configuration, the 2322 supports several factory and dealer-installed options:

Static Moisture Sampler — Improves moisture reading accuracy by sampling only when grain is stationary. Includes debris guards to prevent fines from contaminating the sensor. Strongly recommended on the 2322 because of its high throughput where moisture targeting accuracy directly affects operating efficiency at scale.

Inverters (VFDs) — Available on the 2322. VFD upgrades allow finer control over fan and auger speeds, reducing energy consumption at partial loads.

Small Grain Screen — 0.055″ perforations for canola and other small grains. Reduces corn capacity by approximately 20% when installed.

X-Stream Upgrade (2322X configuration) — Available at order. The X-Stream fan rearrangement improves heat distribution from front to back of the dryer for measurably better grain uniformity at the same throughput.

Best Applications for the 2322 and 2322X

The 2322 and 2322X fit specific operational profiles, and the right configuration depends on grain quality requirements.

Best fit for the 2322:

• Large farms handling 8,000–11,000 acres of corn
• Operations primarily running Continuous Dry & Cool or All Heat where grain uniformity isn’t a premium grading factor
• Three-phase farmsteads needing more capacity than the 2320 delivers but less than the 2326 flagship
• Farms upgrading from a 2320 where capacity became the bottleneck
• Custom drying operations needing reliable Full Heat throughput in the 2,000–2,300 BPH range

Best fit for the 2322X:

• Food-grade corn producers operating at 2,200+ BPH throughput
• Seed corn operations
• Malting barley growers (with small grain screen)
• Specialty grain producers selling into markets where overdried or unevenly dried kernels are penalized
• Any operation where the longer 22-foot grain column’s potential for front-to-back heat variation justifies the X-Stream investment

Less suitable for:

• Single-phase farmsteads (the 2322 is three-phase only)
• Operations consistently exceeding 2,500 BPH demand — step up to the 2326
• Pure All Heat operations at lower throughput where a single-module dryer would deliver adequate capacity at much lower cost
• Sites with strict installed height limits (the 25′ 11″ installed height applies)

How the 2322 Compares to Adjacent Models

2322 vs 2320 / 2320X: The 2322 adds 2 feet of grain column (22′ vs 20′), upgrades the top fan from 25 HP to 30 HP, and steps the top heater from 7.5 to 8.75 Mil. BTU/hr. The lower module remains identical between the two models. The result is 190 BPH more Full Heat capacity at 5-point removal (2,200 vs 2,010 BPH) — about 9% more throughput. Choose the 2322 if your typical drying volume regularly exceeds 1,800 BPH; choose the 2320 if 2,000 BPH is sufficient and the additional capacity isn’t justified by harvest volume.

2322 vs 2326 / 2326X: The 2326 represents a major step up — column extends from 22′ to 26′, top fan jumps from 30 HP to 40 HP, top heater grows from 8.75 to 10.25 Mil. BTU/hr, and the lower module gets a substantial upgrade (25 HP fans vs 15 HP, 6.75 Mil. BTU/hr heaters vs 4.5 Mil.). Full Heat capacity rises to 2,700 BPH — about 23% more than the 2322. Choose the 2326 only when consistent throughput above 2,400 BPH justifies the capital and infrastructure step up; otherwise the 2322 delivers most of the capacity at significantly lower cost.

2322 vs 1226S/H (1200S&H flagship): The 2322 delivers 65% more Full Heat capacity (2,200 vs 1,330 BPH) and 2.5x the Dry & Cool capacity (1,500 vs 600 BPH). The trade-offs are significantly higher capital cost, three-phase requirement, and substantially taller installed footprint (25′ 11″ vs 14′ 6″). Choose the 2322 if you need the capacity step up and your site/electrical can accommodate; choose the 1226 if the height matters and All Heat is your primary mode.

Frequently Asked Questions

What is the difference between the 2322 and 2322X? The 2322 uses GSI’s standard three-fan layout for the 2300 Series. The 2322X uses the optional X-Stream fan rearrangement, which improves heat distribution from front to back of the dryer for more uniform grain quality. Capacity ratings are effectively identical between the two configurations.

What is the holding capacity of the GSI 2322? Both the 2322 and 2322X have a total holding capacity of 1,149 bushels, with 1,067 bushels in the active grain column across both modules.

What is the maximum drying capacity of the 2322? At 5-point moisture removal (20% to 15%) in Full Heat mode, the 2322 delivers up to 2,200 BPH on standard corn — effectively identical between standard and X-Stream configurations. In Dry & Cool mode at the same moisture removal, the 2322 delivers up to 1,500 BPH.

Can the 2322 run on single-phase power? No. The 2322 is three-phase only. The 30 HP top fan motor and 15 HP lower module fans exceed practical single-phase service limits. For single-phase operation in the 2300 Series, only the 2314 is available.

Why does the 2322 share the same lower module as the 2320? The lower module configuration on both the 2320 and 2322 (two 15 HP fans, two 4.5 Mil. BTU/hr heaters) is engineered to handle secondary drying and cooling for both throughput levels. The capacity gain from 2320 to 2322 comes from upper module upgrades and column extension, not lower module changes. This shared lower module sizing represents the upper limit before the 2326 requires a full lower module redesign.

What’s the capacity difference between the 2322 and 2326? The 2326 delivers 23% more Full Heat capacity (2,700 vs 2,200 BPH) but requires significantly larger fans (40 HP top fan vs 30 HP), larger heaters (10.25 Mil. BTU/hr top heater vs 8.75 Mil.), a redesigned lower module (25 HP fans, 6.75 Mil. BTU/hr heaters), and greater capital investment. The 2326 is appropriate when consistent throughput above 2,400 BPH justifies the step up.

Does the 2322 support X-Stream? Yes. The 2322X variant is available with the X-Stream fan rearrangement at order. X-Stream cannot typically be retrofitted in the field.

What’s the difference between the 2322 and the 1222S/H? The 2322 is a two-module dryer with three fans and three drying stages. The 1222S/H is a single-module dryer with two fans and two drying stages. Both use 22-foot grain columns, but the 2322 holds nearly twice the grain (1,149 BU vs 599 BU) and delivers more than double the Full Heat capacity (2,200 BPH vs 1,080 BPH). The 1222S/H can run on single-phase power; the 2322 cannot.

What fuel does the 2322 use? Both 2322 configurations support both liquid propane (LP) and natural gas (NG), selectable at order configuration.

What is the transport weight of the 2322? Approximately 22,500 lbs (less transport kit) — identical between the standard 2322 and the 2322X configurations.

What is the installed height of the 2322? The 2322 has an installed height of 25′ 11″ (excluding foundation supports). This is identical across all 2300 Series models because it represents the structural height of the two-module stack.

Does the 2322 support remote monitoring? Yes. Both 2322 configurations ship with Vision Controls and are GSI Connect compatible, enabling full remote monitoring and control of all three plenum temperatures and unload speeds.

Can the 2322 dry canola or other small grains? Yes, with the optional small grain screen (0.055″ perforations). Capacity on corn is reduced by approximately 20% when the small grain screen is installed.
