FIELD: drying of plant materials, in particular, drying of food products such as vegetables, mushrooms, fruit, greens, spices etc.
SUBSTANCE: method involves directing heat-carrier in drying chamber-heat exchanger-condenser system along closed flow cycle defined by drying chamber outlet-heat exchanger-condenser inlet-heat exchanger-condenser outlet-drying chamber inlet; dehydrating heat-carrier by condensing moisture vapors available in heat-carrier on walls of heat exchanger-condenser dissipater; newly heating heat-carrier to temperature of 85-95 C and directing through drying chamber until the moment vacuum pulse starts acting upon product to be dried; removing moisture generated in heat exchanger-condenser by opening valves connecting heat exchanger-condenser with sluice chamber.
EFFECT: improved quality of drying process reached through employment of equipment.
