GSI 2320 & 2320X Portable Grain Dryer

The GSI 2320 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 1,044 bushels of holding capacity and Full Heat drying performance up to 2,010 BPH at 5-point moisture removal, the 2320 is the first model in the 2300 Series to break the 2,000 BPH threshold — and the first to offer the X-Stream uniformity upgrade as the 2320X variant.

The 2320 represents a critical positioning step in the 2300 Series. Below this point (the 2314 and 2318), the series focuses on cost-effective entry into two-module drying. At the 2320 and above, the focus shifts to high-throughput, high-uniformity operation — capacity numbers approach the lower end of three-module 3400 Series performance, and X-Stream variants become available for operations where grain quality directly affects pricing.

For operations handling 7,000 to 10,000 acres of corn — or any grain operation needing reliable Continuous Dry & Cool throughput in the 1,400–1,500 BPH range with optional uniformity optimization — the 2320 frequently represents the optimal balance between capacity, capital cost, and quality flexibility.

2320 vs 2320X — Configuration Choice

The 2320 is offered in two configurations. Both share identical drying performance, fans, heaters, and grain column. The difference is the fan layout.

2320 — Standard Configuration

The standard 2320 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 2,010 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. Most general-purpose corn drying applications fit this profile.

2320X — X-Stream Variant

The 2320X is a 2320 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 2320 (2,010 BPH Full Heat at 5-point removal), 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 becomes meaningful at the 2320 capacity level because the longer 20-foot grain column has greater potential for front-to-back heat variation than shorter columns earlier in the series. The X-Stream layout effectively neutralizes that variation.

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.

Unlike the 1200S&H Series — where X-Stream is restricted to the H-Series body only — there’s no S/H distinction within the 2300 Series. The 2320X is simply the 2320 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 2320 and 2320X share identical capacity ratings.

Mode	Moisture Removal	Capacity
Full Heat	30% to 15%	920 BPH
Full Heat	25% to 15%	1,250 BPH
Full Heat	20% to 15%	2,010 BPH
Dry & Cool	25% to 15%	850 BPH
Dry & Cool	20% to 15%	1,380 BPH

The 2320 hits 2,010 BPH in Full Heat at 5-point removal — the first model in the 2300 Series to clearly exceed 2,000 BPH and a 11% increase over the 2318. The capacity gain is delivered by extending the grain column from 18′ to 20′, upgrading the top fan from 20 HP/42″ to 25 HP/42″, stepping the top heater from 6.75 to 7.5 Mil. BTU/hr, and significantly upgrading the lower module with 15 HP/36″ fans and 4.5 Mil. BTU/hr heaters (versus 10–12 HP/36″ fans and 3.5 Mil. BTU/hr heaters on the 2318).

In Dry & Cool mode, the 2320 delivers 1,380 BPH at 5-point removal — 11% more than the 2318 and a meaningful step toward the 2,000+ BPH continuous-cooling territory of the larger 2300 models. For operations whose primary mode is continuous cooled-grain drying, the 2320 represents the threshold where two-module Dry & Cool capacity starts to compete directly with the lower end of three-module 3400 Series performance.

The 2320X delivers identical capacity numbers but with measurably better grain uniformity — an advantage that becomes increasingly visible at this throughput level.

Fan & Heater Configuration

The 2320 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 @ 25 HP, 42″
• 1 heater @ 7.5 Mil. BTU/hr

Lower module:

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

The 2320’s upgrades over the 2318 are substantial across both modules. The upper fan grows from 20 HP to 25 HP (+25% horsepower), the upper heater grows from 6.75 to 7.5 Mil. BTU/hr (+11% thermal output), and most importantly, the lower module gets a major upgrade — fans step from 10–12 HP to 15 HP, and heaters step from 3.5 to 4.5 Mil. BTU/hr each (+29% thermal output per lower heater). The lower module upgrade is what enables the 2320 to support the higher overall throughput without bottlenecking at the secondary drying stage.

In the 2320X 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.

The 2320 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: 94–127 amps
• 575V three-phase: 78–105 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 2320 class, this is rarely cost-effective compared to upgrading the farmstead’s electrical service.

Grain Column & Holding Capacity

The 2320 uses standard 14-inch wide grain columns measuring 20 feet long. Total holding capacity is 1,044 bushels, with 970 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 20-foot column length is identical to the 1220S/H in the 1200S&H Series, but because the 2320 stacks two modules, it holds nearly twice the grain at any given moment (1,044 BU vs 544 BU on the 1220). 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 — a step up from the 5 HP loader on the 2314 and 2318 — with a peak loading rate of 3,800 BPH. The larger motor handles the 2320’s longer column without extending fill time relative to smaller 2300 models, 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 2,800 BPH — meaningful headroom over the 2320’s actual maximum throughput of 2,010 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 2320 target a specific exit moisture content and adjust unload speed dynamically as inlet moisture varies. At the 2320’s throughput level, dynamic moisture targeting consistently reduces overdrying losses by 1–2% — which on 80,000+ bushels per harvest season translates to meaningful dollar savings.

Operating Modes

The 2320 and 2320X 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: 2,010 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 2320 at peak All Heat capacity should size cooling bin infrastructure accordingly.

Continuous Dry & Cool — Full continuous flow with integrated cooling. Grain exits cooled and ready for direct binning at up to 1,380 BPH. The 2320’s three-stage architecture and upgraded lower 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 2320X 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.

Transport & Installed Dimensions

The 2320 is engineered as a portable dryer despite the larger two-module stack. Operators planning to relocate the 2320 should confirm tractor or truck capacity is rated for portable grain handling equipment in the 21,000+ lb class.

Dimension	Transport	Installed
Length	29′ 2″ (hitch to discharge auger)	29′ 10″
Width	8′	8′ 8″
Height	13′ 5″ (11′ 9″ shortest)	25′ 11″ (excl. foundation supports)
Approximate Weight	21,000 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 1220 installed height is 14′ 6″) and is the most important physical consideration when planning a site for the 2320 versus a single-module alternative.

At 21,000 lbs transport weight (less transport kit), the 2320 is about 2,000 lbs heavier than the 2318 — primarily from the longer column, larger top fan, and more substantial lower module fans and heaters.

Vision Controls

The 2320 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 2320’s larger 7.5 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 2320 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 2320 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 2320’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.

Optional Equipment

Beyond the standard configuration, the 2320 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 2320 because of its high throughput where moisture targeting accuracy directly affects operating efficiency at scale.

Inverters (VFDs) — Available on the 2320. 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 (2320X 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 2320 and 2320X

The 2320 and 2320X fit specific operational profiles, and the right configuration depends on grain quality requirements.

Best fit for the 2320:

• Medium to large farms handling 7,000–10,000 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 2318 delivers but less than the 2326 flagship
• Farms upgrading from a 2314 or 2318 where capacity became the bottleneck
• Operations at the throughput level where two-module dryers compete with smaller three-module alternatives

Best fit for the 2320X:

• Food-grade corn producers operating at 2,000+ 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 20-foot grain column’s potential for front-to-back heat variation justifies the X-Stream investment

Less suitable for:

• Single-phase farmsteads (the 2320 is three-phase only)
• Operations consistently exceeding 2,500 BPH demand — step up to the 2326 or larger
• 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 2320 Compares to Adjacent Models

2320 vs 2318: The 2320 represents a significant capacity step up: column extends from 18′ to 20′, top fan upgrades from 20 HP to 25 HP, top heater grows from 6.75 to 7.5 Mil. BTU/hr, and lower module gets major upgrades (15 HP fans vs 10–12 HP, 4.5 Mil. BTU/hr heaters vs 3.5 Mil.). The result is 200 BPH more Full Heat capacity at 5-point removal (2,010 vs 1,810 BPH) and X-Stream availability that the 2318 lacks. Choose the 2320 if you need to break the 2,000 BPH threshold, want X-Stream uniformity benefits, or expect significant Dry & Cool throughput demand.

2320 vs 2322 / 2322X: The 2322 adds 2 feet of grain column (22′ vs 20′) and steps the top fan and heater up (30 HP/42″ top fan vs 25 HP/42″, 8.75 Mil. BTU/hr top heater vs 7.5 Mil.). Full Heat capacity rises to 2,200 BPH — about 9% more than the 2320. Choose the 2322 if your typical drying volume regularly exceeds 1,800 BPH and the additional capacity justifies the step up.

2320 vs 1226S/H (1200S&H flagship): The 2320 delivers 51% more Full Heat capacity (2,010 vs 1,330 BPH) and more than double the Dry & Cool capacity (1,380 vs 600 BPH). The trade-offs are significantly higher capital cost, three-phase requirement (1226 supports single-phase), and substantially taller installed footprint (25′ 11″ vs 14′ 6″). Choose the 2320 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 2320 and 2320X? The 2320 uses GSI’s standard three-fan layout for the 2300 Series. The 2320X 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 identical between the two configurations.

What is the holding capacity of the GSI 2320? Both the 2320 and 2320X have a total holding capacity of 1,044 bushels, with 970 bushels in the active grain column across both modules.

What is the maximum drying capacity of the 2320? At 5-point moisture removal (20% to 15%) in Full Heat mode, the 2320 delivers up to 2,010 BPH on standard corn — identical between standard and X-Stream configurations. In Dry & Cool mode at the same moisture removal, the 2320 delivers up to 1,380 BPH.

Can the 2320 run on single-phase power? No. The 2320 is three-phase only. The 25 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.

What does X-Stream actually do? X-Stream is a rearrangement of the dryer’s fan layout that optimizes airflow distribution from front to back of the grain column. It produces more even heat exposure across the column depth, which means fewer overdried kernels at hot spots and fewer wet pockets at cooler spots. The result is more uniform grain quality at the same throughput.

Can X-Stream be added to a standard 2320 later? X-Stream is specified at order and is generally not retrofitted in the field. Operations expecting to need X-Stream should specify the 2320X configuration when ordering.

Is the 2320 the first 2300 Series model to break 2,000 BPH? Yes. The 2320 hits 2,010 BPH in Full Heat at 5-point removal — the first 2300 Series model to exceed 2,000 BPH. The 2318 below it delivers 1,810 BPH; the 2322 above it delivers 2,200 BPH.

What’s the difference between the 2320 and the 1220S/H? The 2320 is a two-module dryer with three fans and three drying stages. The 1220S/H is a single-module dryer with two fans and two drying stages. Both use 20-foot grain columns, but the 2320 holds nearly twice the grain (1,044 BU vs 544 BU) and delivers more than double the Full Heat capacity (2,010 BPH vs 990 BPH). The 1220S/H can run on single-phase power; the 2320 cannot.

What fuel does the 2320 use? Both 2320 configurations support both liquid propane (LP) and natural gas (NG), selectable at order configuration.

What is the transport weight of the 2320? Approximately 21,000 lbs (less transport kit) — identical between the standard 2320 and the 2320X configurations.

What is the installed height of the 2320? The 2320 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 2320 support remote monitoring? Yes. Both 2320 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 2320 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.
