The drying column is formed by an upper feed/recovery hopper and a certain number of modules inside which ducts are buried in the grain. The grain drops by way of gravity in a zig-zag pattern.
The grain is struck by a counter-current of warm air in the top drying part, and room-temperature air in the lower cooling part. The exhaust air is dispersed directly into the atmosphere.
The quantity of grain in outfeed is predetermined and regulated by a pneumatic extractor.
The product is then collected in a discharge hopper.
