CONTROL METHOD OF GRAIN DRYING PROCESS BY ELECTRICALLY ACTIVATED AIR Russian patent published in 2014 - IPC F26B25/22 F26B3/02 

FIELD: heating.

SUBSTANCE: control method of a grain drying process by electrically activated air as a drying agent consists in the fact that initial and current grain humidity, temperature and relative humidity of atmospheric air is controlled, relative humidity of air supplied to a grain layer is controlled, and operation of an air ion source is controlled. Operation of the air ion source is controlled as per minimum criterion of grain drying time by selecting one of the two modes - with constant concentration of air ions in a drying agent, with cyclic change of air ion concentration in the drying agent, which is chosen depending on the grain state and characteristics of the drying agent; besides, concentration of air ions does not exceed 3.5·10¹⁰ m^-3, and duration of air ion source activation cycles is in the range of 5-60 minutes and depends on culture.

EFFECT: improving drying intensity; reducing specific energy consumption for a drying process.
