摘要

The device for altering flow of air into a dryer fitted with air conduits, used for drying seeds (eg. cereal grain or oil-producing plant seeds) comprises a throttle valve mounted on one or more of the nozzles in the air conduits facing the air inlet or outlet side of the dryer. The valve is formed by a sheet which can be moved at right angles to the length of the conduits.
