GSI Portable Stack Dryers

GSI has been and will continue to be the market leader in grain drying technology. We built our first Portable Dryers in 1988, then delivered the first computerized controls in 1993. Three generations of computerized controls later, we lead the industry in control technology.

Vision Controls

Vision controls offer simple operation, with an easy-to-read large color graphical touch display. Located on the dryer or remote with a few wires, these controls are design specifically for GSI grain dryers, giving you unmatched options and settings to get exactly what you need from your dryer control.

Grain Inverters

Our grain inverters move all but the outside two inches of grain, promoting higher test weights, maximum grain quality, and reduced fuel usage. The 2 inches of wet grain is dried using the heat that would have otherwise escaped the dryer. When using inverters, you eliminate over-dried grain and maximize drying efficiency as well as grain quality as you simplify your operation with a convenient clean-out door for easy and quick maintenance.

New Static Moisture Sampler

Improve your moisture sample accuracy with the new Static Moisture Sampler. Our sampler only takes readings when the grain is static and not flowing and features debris guards to ensure a trash free, accurate sample.



WatchDog allows you to monitor and control your dryer from anywhere. Monitor and adjust moisture and temperature from your phone, tablet, or computer with ease.​

Noise Suppression System

If you desire ultra-quiet operation for your dryer, even quieter than centrifugal fan models, choose the Noise Suppression sytems.  Reduces noise levels to over 85%.

7" Metering Rolls

7” Metering rolls unload more evenly over the entire width of the columns reducing the need for grain column adjustments.


One size does not fit all when it comes to drying grain, and that’s why GSI features a complete lineup of grain dryers. With the ability to dry in or out of bin, batch or continuous flow we have the dryer to fit your needs and maximize your profitability.
