FIELD: agriculture.
SUBSTANCE: method for drying green vegetable materials with the use of microwave treatment includes compacting them before drying to the bulk density of 130-300 kg/m3, drying green vegetable materials, carried out in two stages, at the first of which they are treated by microwave radiation with the frequency of 915 or 2450 MHz with the specific power providing the heating intensity from 1 to 10°C per second to the temperature of 60-90°C, and the finish drying of partially dehydrated vegetable materials and moisture evaporation are carried out by the method of convection drying with a stream of heated air, which ensures that the temperature of vegetable materials does not exceed 60°C.
EFFECT: invention will allow to improve the drying of green vegetable materials and to prevent excessive destruction of carotene contained therein.
