FIELD: agriculture. SUBSTANCE: drying chamber is equipped with grain moisture reading circuit 2, K circuits for regulation of temperature of heat carrier in K regions of drying chamber 1. All circuits are connected by means of correction circuits 27, 28 and 29. Setting values for K circuits for regulation of temperature of heat carrier in regions 5 is produced by K regulation units 21 and is corrected by K correction units 31. Regulation units 21 provide tolerant temperature levels of heat carrier in regions 5 according to condition of grain heating limitation taking into account its moisture. Correction units 31 correct temperature of heat carrier according to condition of grain drying rate limitation. EFFECT: increased precision of regulation and output production of drying chamber using additional monitoring of grain drying rate in K regions in vertical direction and correction of temperature of heat carrier, when drying rate exceeds limit. 2 cl, 1 dwg
