Heat pump and microwave combined wood drying equipment and wood drying method

Abstract

The invention relates to heat pump and microwave combined wood drying equipment and a wood drying method. The heat pump and microwave combined wood drying equipment is characterized by comprising a drying room, magnetrons, an inner air duct, an outer air duct, a heating chamber, a condenser, a first draught fan, a heat exchange core body, a first evaporator, a second draught fan, a drying chamber,a second evaporator, a third draught fan, a first electronic expansion valve, a second electronic expansion valve, a four-way valve and a compressor; the magnetrons and the inner air duct are all arranged in the drying room; the outer air duct and the heating chamber are both arranged outside the drying room; the drying chamber is arranged beside the heating chamber; the compressor communicates with the condenser through the four-way valve; the condenser communicates with the first evaporator through the first electronic expansion valve; and the condenser communicates with the second evaporator through the second electronic expansion valve. The heat pump and microwave combined wood drying equipment has the advantages that the drying equipment conducts drying in a heat pump and microwave combined mode; the drying equipment can control the environmental temperature and humidity and the water evaporation speed in the drying process better by integrating the advantage of the good dehumidifying effect of a heat pump and the advantage of the high microwave water evaporation speed; and thus, the high quality of dried products is realized.

Description

technical field [0001] The invention relates to a heat pump microwave wood combined drying equipment and a wood drying method. Background technique [0002] During the drying process of wood, according to the characteristics of wood, the required ambient temperature and humidity are different at different stages of drying, and the evaporation rate of water is also different; therefore, a single drying method, such as pure electric heating, pure heat pump and Pure microwave, etc., it is difficult to optimize the drying process, which affects the drying quality of wood. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a heat pump microwave wood combined drying equipment and wood drying method, which adopts the combination of heat pump and microwave for drying, and combines the advantages of good dehumidification effect of heat pump and microwave water evaporation speed The advantage of being...
