GSI 1122 Grain Dryer

A serious portable dryer for farms that need more throughput

The GSI 1122 Grain Dryer sits near the top of the GSI 1100 Series, giving growers more drying capacity while staying within the same simple single-module portable layout. That matters for farms that want stronger harvest performance but still prefer a dryer family that is easier to size and easier to understand than a larger multi-module system. GSI positions the 1100 Series for farms using bins of 50,000 bushels or less with adequate cooling air, and presents it as a practical option for operations stepping into on-farm high-speed drying.  

For Aglist users in Canada, the 1122 is the kind of model that can appeal to farms where the smaller 1118 or 1120 may start to feel limiting during wetter harvest conditions. It gives a stronger output ceiling, but still remains inside the more straightforward 1100 Series concept rather than moving into a bigger expandable dryer platform.  

Where the GSI 1122 fits in the 1100 Series

The official 1100 Series lineup includes 1108, 1112, 1114, 1116, 1118, 1120, 1122, and 1126. Across the full family, GSI lists roughly 420 to 1,160 BPH all-heat drying at 5-point removal and about 219 to 708 bushels of holding capacity, depending on model. That places the 1122 very close to the upper end of the lineup, below only the 1126 in this family.  

This positioning is useful in real buying decisions. The 1122 is not the smallest or simplest-capacity choice in the family, but it is still part of a portable dryer range designed for growers who want solid output without stepping into larger stacked or multi-fan dryer classes.  

GSI 1122 drying performance

According to GSI’s published 1100 Series specifications, the GSI 1122 Grain Dryer is rated at 1,020 BPH in Full Heat 20% to 15%, 630 BPH in Full Heat 25% to 15%, and 460 BPH in Full Heat 30% to 15%. In Dry & Cool staged batch, it is rated at 530 BPH at 20% to 15% and 400 BPH at 25% to 15%.  

Those numbers show why the 1122 stands out inside the 1100 Series. For farms dealing with tighter harvest windows, wetter corn, or more pressure on labour and trucking, this model offers a meaningful step up from the smaller dryers in the same family. Of course, brochure numbers are only part of the story, but they do show that the 1122 is built for operations needing stronger throughput from a portable unit.  

Capacity, construction, and size

GSI lists the 1122 as a 1 module, 1 stage dryer with a grain column size of 14 inches x 22 feet long. Total holding capacity is shown at 598 bushels, with 517 bushels of grain column holding capacity.  

The dimension table lists the 1122 with a transport length of 31’2”, transport width of 8’, and transport height of 13’5”. Installed dimensions are 29’2” long, 8’ wide, and 14’6” high. Approximate transport weight is listed at 9,600 lb.  

For Canadian farms, these dimensions matter just as much as output. Yard layout, transport access, concrete pad planning, and the way a dryer fits around existing wet bins or unloading equipment can all affect whether a machine is convenient or frustrating to live with.  

Augers, unloading, and grain handling

In the 1100 Series specification chart, the GSI 1122 is listed with an 8-inch top auger rated at 7.5 HP and an 8-inch flight / 10-inch tube bottom auger also rated at 7.5 HP. Top auger capacity is shown at 3,800 BPH. The meter roll drive is listed as VFD, 1 HP, and maximum capacity is shown at 2,800 BPH.  

These details help buyers look beyond one headline drying number. Real-world dryer performance also depends on feed consistency, unload control, and how smoothly grain moves through the machine over long harvest days. That is why buyers often compare auger and discharge details alongside BPH ratings instead of focusing on one figure alone.  

Heater, fan, and electrical details

The heater on the GSI 1122 is listed at 8.5 million BTU/hr. In the published lineup specs, the three-phase fan for the 1122 is shown as 25 HP, 42-inch, and the table does not list a single-phase option for this model.  

Electrical requirements in GSI’s chart are shown at 117/193 amps for three-phase 208 V, 107/178 amps for three-phase 230 V, 56/89 amps for three-phase 460 V, and 46/73 amps for three-phase 575 V. These numbers should be looked at carefully during planning because site power can strongly affect the real installed cost of a dryer. A unit that fits the farm on capacity may still require electrical work that changes the economics of the purchase.  

Drying style and crop-use flexibility

GSI says the 1100 Series is primarily an all-heat corn drying system, but also notes that it can be used in Continuous Batch Dry & Cool operation either full time or for specific situations. The company specifically mentions uses such as putting a dry cone in a flat-bottom wet bin, or handling occasional soybean or wheat drying where cooled grain is needed.  

That makes the 1122 more flexible than a one-line category description might suggest. The final fit still depends on crop mix, storage airflow, target moisture removal, and harvest strategy, but GSI’s own description makes it clear that the 1100 Series is not limited to only one narrow application.  

What makes the GSI 1122 attractive to buyers

From an Aglist perspective, the GSI 1122 Grain Dryer stands out because it offers near-top-end capacity within a simpler single-module portable family. That can be attractive for farms that want more throughput and more harvest breathing room, but still do not want the added complexity of moving into a larger dryer class.  

It can be especially appealing for growers who already know they need more than the mid-range 1100 Series models can comfortably offer, yet still want a portable dryer that feels realistic to place, power, and manage on a small- or medium-sized operation.  

Real-world buying questions

Is the GSI 1122 enough for a mid-sized grain operation?

It can be, and in many cases it will feel like a strong-capacity option within the 1100 Series. On paper, the 1122 offers 1,020 BPH at 20% to 15% in Full Heat and 598 bushels of total holding capacity, which puts it close to the top of this family.  

Is the 1122 still a good first dryer?

In some cases, yes. That aligns with how GSI positions the 1100 Series overall as a strong first high-speed dryer. The main question is whether the farm actually needs this much capacity or whether a smaller model would be a better match financially and operationally.  

Can it work for crops besides corn?

GSI says yes, in the right setup. While the series is mainly described as an all-heat corn dryer, it can also be used in Dry & Cool operation for occasional soybean or wheat drying where cooled grain is needed.  

Final thoughts

The GSI 1122 Grain Dryer is a strong fit for farms that want near-top-end 1100 Series performance while keeping the same practical single-module concept. With published output up to 1,020 BPH at 20% to 15% in Full Heat, 598 bushels of total holding capacity, and a portable design aimed at small- to medium-sized farms, it fills an important place for buyers who want more throughput without moving into a more complex dryer family.  

For Aglist, this page works best as a model-focused resource built around specifications, buyer comparison, farm-fit decisions, and later owner feedback. It is exactly the kind of page where real operator experience can make the listing even more valuable over time.
