METHOD OF DRYING PLANT-BASED MATERIAL AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2017 - IPC A23B7/02 F26B5/04 F26B9/06 F26B20/00 

FIELD: heating.

SUBSTANCE: method of drying material and device for its implementation includes repeating cycle - the sequence of operations in the closed volume of the drying chamber, including heating of the plant-based material by means of the coolant upto the temperature that does not cause denaturation, and vacuum degassing with exposure after vacuum degassing, at that during repeated at least twice the operation cycle of drying plant-based material with exposure at vacuum degassing the pressure of the moisture vapors in the drying chamber - heat exchanger system is reduced by cooling, condensation and dehydration of coolant and simultaneously reduce the moisture vapor pressure in the receiver and the temperature of the condensate in the air lock chamber by means of radiators, to which the cold water is supplied, mounted in the heat exchanger and the air lock chamber cavities. The dehydration of the coolant in the drying chamber - the heat exchanger system is performed, while it is moving along the closed cycle the output from drying chamber - input to the heat exchanger - the output from the heat exchanger - the input to the drying chamber, whereupon the coolant is heated again upto the average bulk temperature of 70-115°C and again pass it through the drying chamber before starting to affect on the drying product of the second vacuum impulse.

EFFECT: invention should provide intensification of the drying process by reducing the drying time.
