Grain drying

One or more silos for moist grain, called wet bins or buffer silos, are often part of the drying plant. These work as pre-bins for the dryer, and ease separation of moist and dry grain, by which they contribute to an optimum utilization of the drying plant. The silo works as pure buffer/storage bin, and has a typical capacity of 40-100 tons.

Generally speaking, there are two principles for drying; continuous flow drying and on-floor drying. The continuous flow dryer is characterized by a high degree of flexibility when drying different raw materials. It is also suitable for very moist products. The continuous flow dryer is often used in grain storage plants with large outdoor flat-bottom steel silos.

The on-floor drying plant combines the storage and drying function. It is suitable for drying of grain and seeds, but not for very moist products.
