Abstract

The invention discloses a ventilating dryer capable of recovering waste heat and a control method thereof and belongs to the field of crop drying. The ventilating dryer capable of recovering waste heat is formed by additionally arranging a set of air return device on the basis of a reversible ventilating dryer; the air return device comprises a left exhaust duct, a right exhaust duct, upper ventilating ducts and detection control equipment, wherein the left exhaust duct is communicated with a left drying chamber; the right exhaust duct is communicated with a right drying chamber; the left and right exhaust ducts are communicated with an air inlet duct through the upper ventilating ducts; joints of the ventilating ducts are provided with control valves; the air return device and a reversing device are coordinated to realize the first and second drying processes. The invention provides a set of drying method based on the structure of the ventilating dryer. By combining the dryer and the drying method, hot air can be recycled, the waste of energy is reduced, and support is provided for developing green agriculture.

Description

technical field [0001] The invention relates to a box-type dryer and a control method thereof, in particular to a ventilated dryer capable of recycling heat and a control method thereof. Background technique [0002] With the rapid development of mechanized harvesting of grain and oil crops in rural areas in my country, due to the lack of drying facilities in the production area and the limitation of rainy weather, high-moisture grain and oil materials cannot be dried in time, resulting in mildew loss and other problems are very prominent. The box-type ventilated dryer is an economical and practical grain dryer with simple structure, convenient operation, flexible configuration and low price, and can be adapted to drying different agricultural products. The equipment has good versatility, high utilization rate and long investment recovery period Short, more suitable for the actual production and economic conditions of rural farmers in my country. See attached for specific st...
