FIELD: food industry.
SUBSTANCE: invention relates to methods of treating food industry and can be used in production of natural dry derivatives from vegetable raw materials. Method consists in the fact that the vegetal raw material layer is blown with a drying agent in two stages, conditioning and crushing. Temperature of the drying agent is 30–40 °C, and vegetal raw materials are placed in one layer on shelves of trolleys-racks. In the process of drying, the racks-trolleys are periodically rotated relative to their location and their own axis.
EFFECT: method increases efficiency of raw material flow with heat carrier.
