外文摘要：The grain drying system includes a controller electronically connected to a variable speed fan and a heater or heat pump coupled to an air duct to deliver air through the duct and over the grain in the grain silo. An ambient temperature sensor and an ambient humidity sensor, an intra-duct temperature sensor and an intra-duct humidity sensor are also connected to the controller. The system operates by the controller adjusting the fan speed together with heater or heat pump operation so that during the first period when the ambient air is outside the target equilibrium humidity range, air at the target equilibrium humidity temperature is supplied. The controller also operates the variable speed fan at a predetermined minimum speed during the second period when the ambient air is outside the target equilibrium humidity range and the controller is not, given the operating limits of the variable speed fan and the heater or heat pump, able to obtain air in the duct within the target equilibrium humidity range.
