Abstract

The article is devoted to the problem of drying seeds without their thermal injury by applying vacuum technology. In this paper work presents experimental studies of vacuum drying of seeds of grain crops on the example of maize seeds, during which the safe drying regimes were studied, in which the most intense water separation occurs. It has been found that by heating the batch of seeds to 30° C and subsequent evacuation to a pressure of 4 kPa with bubbling under atmospheric pressure is most intense dehumidification at a rate of 0.259%/min.
