Tower Dryers
The GSI Tower dryer design utilizes industry proven drying principles along with many unique features to provide the commercial user with a simple, reliable, fuel efficient grain drying system.

The patented Electronic Monitoring Control System (EMCS) offers computerized control of all dryer functions. This "smart" system eliminates guesswork by providing the operator instant information on a large backlit LCD display.

Grain Turners

Standard Tower Dryer Operational Features
Standard operational features on the Tower dryer include double Maxon gas blocking valves on the gas train, exhaust air temperature sensors, plenum high temperature limits, grain level monitoring, continuous flame monitoring, airflow monitoring and motor overload monitoring. GSI also provides a two year parts and labor warranty on Tower Dryers, one of the best warranties in the industry.

How It Works...From the Top
Grain enters the dryer at the top and falls into a self cleaning grain receiving chamber. The chamber creates a grain cushion, and with grain falling on grain, helps reduce plenum roof wear. This chamber also provides a means of distributing grain evenly around the dryer. The garner bin at the top of the dryer has a full 40 inches of wet grain storage. This area is completely sealed to help retain grain dust and particulates. Grain moves down, out of the garner area, and enters 12" wide grain drying columns in the heat section of the dryer. Midway down the heat section of the dryer are GSI's patented grain turners. The turners invert the grain from the inside of the grain column to the outside for more uniformly dried grain. As the grain exits the heat section of the dryer it enters the suction cooling section . Air used to cool grain is recycled through the blower(s) resulting in significant energy savings.

Maxon Safety Valves

Easy Access
All areas of the dryer can be easily accessed through up to four entry ways. Cleanout, inspection, and general maintenance are never a problem with the GSI Tower Dryer.

Discharge Area
Cool, dried grain passes from the cooling section of the dryer into the sealed, hoppered discharge section. Grain is gravity fed down a 45 degree hopper to GSI's patented metering drum. This drum provides a positive, yet gentle means of metering grain uniformly from each column of the dryer and discharging it out the center of the dryer. The drum is driven by a variable speed inverter operated AC motor. The hopper bottom design of the dryer eliminates troublesome sweep augers and sweep arms and provides for quick dryer clean-out.

Sidewall Sheeting
Each GSI Tower dryer features a bolted design, rather than welded, which permits the wide use of galvanized steel ( versus painted steel ) throughout the dryer. In addition, all Tower dryers have stainless steel, roll formed exterior sheeting as a standard feature. These design features simplify dryer erection, improve dryer appearance and promote a long dryer life.

GSI Tower dryers are designed to retain bees wings and particulate matter within the drying columns. The largest standard hole size on the exterior screening of the dryer is 0.078 inch diameter perforation. After the grain is turned, the perforation size drops to a diameter of 0.0625 and 0.056 inches. Solid non-perforated exterior sheets are used at the grain turners and at the top and bottom of the grain columns to help reduce particulates from being expelled from the dryer.
