The oven dryer adopts low noise, high temperature resistant axial flow fan to deliver air, and electric heater or radiator for heating the air. The fan motor drives the wind wheels, after heated by the heater, the hot air are delivered into the drying room through the air duct. Used air is absorbed into the air duct and recirculates. By the constant replenishing of fresh air from the air inlet and discharging of wet and hot air from the humidity outlet, the suitable relative humidity in the heating oven is maintained. The whole circulation system is completely closed, having 35-45% thermal efficiency, while the highest efficiency can reach 70%, saving energy and increasing the economic benefit.
