Abstract

The invention discloses an efficient, energy-saving and graded heating heat pump drying system. The drying system comprises a first system, a second system, a first drying room and a second drying room, a first evaporator is arranged in the first drying room, and a second evaporator is located in the second drying room; an intermediate heat exchanger communicates with a pipeline between a first electronic expansion valve and the first evaporator; the other surface of the intermediate heat exchanger communicates with a pipeline between a second condenser and a second electronic expansion valve; an air duct door A, an air duct door B and an air duct door E are arranged on the first drying room, and a first air duct is arranged between the air duct door A and the air duct door E; an opening is formed near the air duct door A of the first air duct and communicates with an air duct door C through a second air duct; and the air duct door C, an air duct door D and an air duct door F are arranged on the second drying room, a third air duct is arranged between the air duct door F and an air duct door H, a fourth air duct is arranged between the air duct door D and an air duct door J, a first condenser is arranged in the first air duct, and the second condenser is arranged in the fourth air duct.

Description

technical field [0001] The invention relates to the field of air energy heat pump drying, in particular to a heat pump drying system with high efficiency, energy saving and hierarchical heating. Background technique [0002] Heat pump drying is highly efficient, energy-saving, green and environmentally friendly, and has great development prospects. In addition, my country is a large agricultural country, and there are many agricultural products that need to be dried, and the market demand is huge. In the past two years, heat pump drying has developed rapidly, but the efficiency and technology have not yet reached the ideal requirements, resulting in low drying efficiency, unstable control, drying failure accidents, and huge losses. Therefore, in order to ensure drying efficiency and safety, a high-efficiency, energy-saving, two-stage heating drying system is now developed to improve drying efficiency and ensure product quality. The control of this system is stable, and the ...
