At this time, the surface temperature of the evaporator 71 decreases, and when the air flows through the evaporator 71, after heat exchange, the air is cooled, and the mixed water vapor will condense into water droplets to achieve dehumidification. This is a conventional principle and will not be described in detail. The condenser 78, evaporator 71 and other components are all conventional components and will not be described in detail here. A heat dissipation fan is fixed on the condenser 78 in this embodiment.

[0037] The bottom plate of the front gas collecting housing 73 is formed with a screw-through hole, and the upper part of the transparent water storage tank 731 is screwed into the corresponding screw-through hole. It can accumulate water droplets in the front gas collecting housing 73. After a certain period of use, the transparent water storage tank 731 can be disassembled and the water inside can be poured out.

[0038] The lower part of the front outer fixed housing 70 is provided with a bottom water receiving tank body 80, and a hinge shaft extending left and right is fixed in the lower part of the front part of the bottom water receiving tank body 80, and the left and right ends of the hinge shaft are movably connected to the lower parts of the left and right side plates of the front outer fixed housing 70 through bearings, and a flip motor 81 is fixed on the outer side wall of one of the side plates, and the output shaft of the flip motor 81 is a spline shaft, which is inserted into the spline hole at one end of the hinge shaft; The lower part of the front wall plate of the front external fixed shell 70 corresponding to the bottom water receiving trough body 80 is formed with a water outlet groove extending left and right, and the lower part of the front wall surface of the front wall plate of the front external fixed shell 70 corresponding to the bottom water receiving trough body 80 is fixed with a fixed connecting plate 82 by bolts, and the fixed connecting plate 82 covers the water outlet groove.

[0039] An inclined liquid guide plate 83 is fixed on the lower rear wall surface of the front wall plate of the front outer fixed shell 70 above the bottom water receiving trough body 80. The front end of the inclined liquid guide plate 83 is higher than the rear end, and its rear end faces the middle upper part of the bottom water receiving trough body 80.

[0040] An elastic support block 9 is fixed on the bottom surface of the front outer fixed shell 70 just below the bottom water receiving tank body 80 , and the top surface of the elastic support block 9 is pressed against the bottom surface of the bottom water receiving tank body 80 .

[0041] All electrical devices in this embodiment are electrically connected to the control host through electrical connection lines and are controlled and operated by the control host. This is a conventional structure and will not be described in detail here.

[0042] When this embodiment is used, before it is turned on, the compressor assembly in the heat exchange main body shell is turned on first, and at the same time, the heat dissipation fan of the condenser 78 and the suction fan 74 at the evaporator 71 are running. At this time, the air in the main box body 10 flows, and when the wind passes through the condenser 78, the air is heated after exchanging heat with the condenser 78, and then is blown out from the ventilation holes 16 into the main box body 10, and then flows out from the ventilation holes 16 on the other side to the front outer fixed shell 70 to exchange heat with the evaporator 71, so that the air is cooled. When the temperature is cooled, the moisture in the air will condense and drip into the bottom water receiving tank body 80, and then enter the connecting shell 75, and then return to the rear outer fixed shell 70, and exchange heat through the condenser 78 to increase the air temperature, and then enter the main box body 10. At the same time, the corresponding heating rod 76 is turned on and heated, so that the air after heat exchange through the condenser 78 is further heated by the heating rod 76 to increase its air temperature.

[0043] The starch raw material that needs to be dried is placed on the starch discharge tray 100, which is placed on the corresponding discharge position of the inclined upward material conveying frame 30. The starch discharge tray 100 is gradually conveyed upward by the operation of the inclined upward material conveying frame 30, and enters the wire mesh conveyor belt 24 of the uppermost horizontal conveying mechanism 20 of the main box body 10 through the upper feeding slot 12. As the horizontal conveying mechanism 20 runs, it is conveyed to the right, and moves from the horizontal conveying mechanism 20 to the two horizontal support rods of the uppermost material receiving transition frame 50 on the right. At this time, the corresponding induction proximity switch 3 senses it, indicating that it has moved into place, and it transmits the induction signal to the control host, and the control host controls the corresponding lifting mechanism on the upper right side to operate, so that the corresponding moving block 44 descends until the material receiving transition frame 50 at this time. The two lateral support rods of the frame 50 are located at the front and rear of the lateral conveying mechanism 20 below. At this time, the corresponding sensing part of the guide block of the moving block 44 is sensed by the corresponding moving proximity switch 46, indicating that it has moved into place. At this time, the starch discharge tray 100 is placed on the wire mesh conveyor belt 24 of the lateral conveying mechanism 20 below, and the lateral conveying mechanism 20 is in operation at this time, which will cause the starch discharge tray 100 to move to the left along with the wire mesh conveyor belt 24. At the same time, the right-side material receiving transition frame 50 stops for 10 to 15 seconds, and then, the lifting motor 43 of the lifting mechanism is operated to lift the corresponding material receiving transition frame 50 back to its original position until the sensing part of the guide block of the moving block 44 is sensed by the corresponding moving proximity switch 46, indicating that it has moved into place. The starch discharge tray 100 transported on the wire mesh conveyor belt 24 below is transported to the two lateral support rods of the corresponding material receiving transition frame 50 on the left. As before, it descends into the wire mesh conveyor belt 24 of the next lateral conveying mechanism 20, and moves to the corresponding material receiving transition frame 50 on the right as the wire mesh conveyor belt 24 moves. It is placed there in turn and gradually transported downward. It is an S-shaped conveyance in the vertical direction, which increases the running time in the main box body 10. At the same time, this design reduces the space occupied in the length direction and improves space utilization.

[0044] When moving in the main box 10, the hot air is blown out from the ventilation holes 16 on one side to dry the starch discharge tray 100 being transported, so that the water in the starch raw material in the starch discharge tray 100 evaporates, so that the hot air is mixed with water vapor, and then discharged from the ventilation holes 16 on the other side to and enter the corresponding evaporator 71 for condensation, so that the water vapor in the air solidifies into water droplets, which are guided by the inclined liquid guide plate 83 and drip into the bottom water receiving tank body 80; After running for a certain period of time, the fixed connecting plate 82 is opened, and the bottom water receiving trough body 80 is turned outward by running the flip motor 81, so that water can flow out of the bottom water receiving trough body 80 to the outside. This water is generally clean and can be poured directly onto the ground, or a water receiving basin can be placed on the ground before pouring it out.

[0045] It has good use effect and good drying effect.

[0046] Among them, various humidity sensors 2 and temperature sensors 1 can always understand the temperature and humidity conditions in the main box 10. When the humidity is high, all heating rods 76 can be turned on. When the humidity is lowered, the number of heating rods 76 turned on can be gradually reduced. The heating rods 76 in this embodiment are electric heating rods.

[0047] The dried starch discharge tray 100 moves out from the lower discharge slot 13 along the discharge guide plate 160 and falls to the corresponding discharge position of the discharge conveyor frame 60, and leans on the elastic anti-collision block 65 and is sensed by the proximity switch 66, indicating that the starch discharge tray 100 has come out. At this time, the control host controls the first conveying motor 63 of the discharge conveyor frame 60 to run. The first conveying motor 63 is a servo motor, which runs for a certain time, which is exactly the distance that the discharge conveyor belt 61 runs a discharge position. At this time, the subsequent discharge position faces the discharge guide plate 160, and can receive the starch discharge tray 100 coming out of the subsequent discharge guide plate 160. It is very convenient and has a good use effect, and continuous processing can be achieved.
