FIELD: agriculture.
SUBSTANCE: invention relates to agriculture and serves for drying grain crops, as well as for dehydration of other similar products and granulated materials. Said purpose is achieved by using energy-saving shaft drier for grain crops, comprising housing, mesh cylinders, dense bulk layer of grain material, heat carrier supply pipe, sector feeder, wet grain loading pipe and waste heat carrier outlet pipe, it differs from known designs in that it is equipped with internal separation cylinder, movable control cylinder and movable ring for the purpose of energy saving for more complete development of heat carrier.
EFFECT: high degree of coolant development by temperature to increase efficiency of dryer.
