[0022] The front side of the box body 1 is provided with an inlet, and the front of the inlet is provided with a box door 101 hinged to the box body 1. The left side of the box body 1 is fixedly provided with a first sealing cylinder 2 of a right opening structure. A heating device 3 is fixedly arranged in the first sealing cylinder 2. The heating device 3 is a plurality of electric heating wires arranged in front and back. The heating device 3 is used to heat the air in the first sealing cylinder 2. For those skilled in the art, the heating device 3 belongs to the known technology, so it is not necessary to make too much description. The left end of the box body 1 is provided with a connecting hole 102 capable of communicating with the first sealing cylinder 2. The hot air in the heating device 3 enters the box body 1 through the connecting hole 102 to dry the sophora alopecuroides in the box body 1.
[0023] The right end of the inner wall of the box body 1 is fixedly provided with a second sealing cylinder 5 of a right opening structure. Two air filter cartridges 6 are arranged in the second sealing cylinder 5. The air filter cartridges 6 are HEPA filter cartridges capable of capturing and collecting particles greater than 0.3 microns in the air, including dust and bacteria. The upper and lower ends of the air filter cartridges 6 abut against the inner wall of the second sealing cylinder 5 to separate the inside of the second sealing cylinder 5 from the inside of the second sealing cylinder 5. The left side of the second sealing cylinder 5 is provided with an air inlet. The air inlet, the second sealing cylinder 5 and the air outlet jointly form an air duct passing through the air filter cartridges 6. A suction fan 7 is fixedly arranged in the air inlet. The suction fan 7 can suck the air in the box body 1 into the second sealing cylinder 5 for filtration, so as to avoid that the hot air in the box body 1 carries dust and bacteria, and avoid affecting the quality of the sophora alopecuroides.
[0024] The bottom end of the box body 1 is provided with two thread holes arranged in front and back. The diameter of the air filter cartridge 6 is smaller than the inner diameter of the thread hole, so that the air filter cartridge 6 can pass through the thread hole for replacement. An external thread cylinder 8 of an upper opening structure is threadedly arranged in the thread hole. The top end of the external thread cylinder 8 passes through the thread hole and abuts against the bottom end of the air filter cartridge 6.

A connecting pipe 10 communicating with the air inlet is fixedly installed at the top of the second sealing cylinder 5. One end of the connecting pipe 10 far from the second sealing cylinder 5 is fixedly connected to and communicates with the right end of the air duct 9. The air duct 9 can discharge the air filtered by the air filter 6 back into the first sealing cylinder 2 for reheating through the connecting pipe 10, and discharge it back into the box 1 through the connecting hole 102 to achieve a heat circulation drying effect. This can improve the drying effect of bitter beans while saving energy.
[0026] A left-opening air duct 11 is fixedly installed on the left end of the inner wall of the box 1. The first sealing cylinder 2 is connected to the air duct 11 through the connecting hole 102. Multiple air outlets arranged in a rectangular array are opened on the right side of the air duct 11. Exhaust fans 12 are fixedly installed in the air outlets. The multiple exhaust fans 12 arranged in a rectangular array are used to evenly discharge the hot air entering the air duct 11 from the first sealing cylinder 2 into the box 1. The exhaust fan 12 located on the left and the suction fan 7 located on the right form a wind path that flows from left to right, which can improve the drying efficiency of bitter beans.
[0027] Working principle: When drying bitter beans, the bitter beans are placed on a ventilated tray on the drying rack and placed inside the chamber 1. The heating device 3 heats the air in the first sealed cylinder 2 and draws it in and discharges it into the chamber 1 through the exhaust fan 12. The hot air flowing from left to right dries the bitter beans in the chamber 1. Then, it is drawn into the second sealed cylinder 5 by the suction fan 7. After being filtered by the air filter 6, it re-enters the first sealed cylinder 2 through the connecting pipe 10 and the air duct 9 for reheating, so as to realize heat circulation to dry the bitter beans in the chamber 1.
