Sukup Tower Grain Dryers are designed for large farm operations and commercial elevators.Sukup Tower Grain Dryers are designed for large farm operations and commercial elevators.

Whether drying corn, grass seed, rice, grains, cereals or soybeans the Sukup innovative design and the latest state of the art Control guarantees that each seed is given equal, gentle treatment providing a quality finished product. Sukup Tower Grain Dryers feature high-quality components like stainless steel screens, a stainless steel grain table, top-quality blowers and burners, and easy-to-use computerized controls with self-diagnostics.

Sukup Tower Grain Dryers are completely assembled on-site and are available in a variety of sizes from 10′ – 24′ diameter and heights from 56′ – 120′. Capacities of dry product ranges between 1000 – 7000 bu./hr. Sukup Grain Dryers provide fast, efficient drying for large farm operations and commercial elevators.


The product enters the grain dryer from an extra-large wet holding bin at the top of the tower dryer and gravity pulls the grain down through the dryer in a hollow column, like the cement in a culvert. Rotary sensors for choke fill or surge fill are standard equipment. The grain column is 12 ¾” wide for longer air retention and maximum efficiency. Perforated sheets on both sides of this hollow column allow air to move freely through the column of grain while retaining the bulk of the particulate matter so that it doesn’t blow into the atmosphere. Solid sheeting on the outside keeps grain dust and particulate matter confined within the dryer.

Since the warm air originates in the inside of the hollow tube, the kernels on the inside of the column would receive a greater degree of drying, were it not for the grain turner, which moves the kernels from the outside of the column to the inside, so seeds originating at both the outside and the inside of the column receive equal amounts of dry air treatment. Outer sheeting in grain turner section is solid to maintain balanced heat/air distribution in the plenum and to avoid blowing large amounts of particulate matter into the atmosphere.


The grain is heated, turned, and dried in the upper half of the tower dryer and cooled in the lower part of the dryer. When it reaches the bottom of the column it is gathered with paddles rotation around the stainless steel grain table and discharged via an unload sweep into a chain conveyor which transfers it to take-away equipment. Heat is reclaimed and recycled into the plenum to augment the heat produced by the Maxon Burners in the drying section of the tower. Louvered air vents allow control of the amount of ambient air being pulled through for cooling.

Computerized Controls are housed in an aluminum box and handle all of the dryer operations including start-up of blowers and burner and load and unload systems. Self-diagnostics are also included with the controls. An LCD displays discharge moisture percentage and grain temperature, three-minute average moisture content, column temperature and unload speed. Unload speed is adjusted automatically, based on column control temperature set by operator. Spout on discharge provides safe and easy way to sample product for calibrating moisture sensor. Positive discharge system ensures steady unloading and no plugging.

Heavy-duty legs underneath the tower allow plenty of clearance for conveyors, monitoring equipment, etc. Angle ring inlet and discharge allow for easy hook-up to fill and take-away equipment and leveling wheels (patent pending) on paddles ensure consistent grain flow and maximum removal.

Sukup Manufacturing Co provides this information to assist you in choosing the optimal equipment for your situation. Many factors, such as grain variety, maturity levels, grain cleanliness, weather conditions and operation/management, can affect the performance of your tower dryer and results may vary. This information is calculated and is not a guarantee of product specifications or performance. Based on these factors, Sukup specifications should only be used as estimates, and not as a warranty, express or implied, of how a particular Sukup unit will perform under your operating conditions. Because we are continually improving Sukup products, changes may occur that may not be reflected in the specifications.

*BU/Hr (bushels per hour) listed are wet bushels, No. 2 shelled yellow corn at listed moisture content and are estimates based on drying principles, field results and computer simulation.
