FIELD: food, microbiological and chemical industries, applicable for sublimation concentration and drying of frozen aqueous solutions or suspensions, sublimation drying of frozen food products, as well as for concentration or drying of liquid solutions and suspensions.
SUBSTANCE: dehydration of the product under drying is accomplished by its engagement with a liquid drying agent with high depression characteristics by a free mass transfer through a vapor phase in the conditions of a high rarefaction, for evaporation of moisture from the product being dried use is made of the heat of moisture absorption by the liquid drying agent transferred through the heat-conducting walls separating the product under drying from the drying agent.
EFFECT: reduced power consumption.
