Abstract
PURPOSE: To prevent mean drying of a grain from being lowered by bringing an atmosphere into contact with grain to cool it if a grain temperature is a predetermined temperature or higher and a grain moisture is an equilibrium moisture content or more of the atmosphere, and shutting OFF the atmosphere if the grain temperature and moisture are reverse to those as above, and lowering a heating drying temperature by a predetermined temperature. CONSTITUTION: A detected grain moisture value, detected grain temperature, detected hot air temperature, detected atmospheric temperature and detected atmospheric humidity detected by respective sensors 7, 8, 20, 41, 42 are input to an air volume temperature controller 44. When an equilibrium moisture content of the atmosphere calculated by the detected temperature and the detected moisture is the same as or more than the detected moisture value, an on-off valve 5 is opened by a solenoid 17, an atmospheric wind is sucked from a suction slot of a front wall plate, ventilated to a cooling chamber, sucked, and exhausted by an exhauster. And, when the moisture content obtained by the calculation is the same as or lower than the detected value, the valve 5 is closed. And, a fuel amount sucked by a fuel pump 22 is controlled by the controller 44, and a hot air temperature is controlled to lower, for example, by 5 degrees stored in a CPU 48.
