[0020] In order to make the purpose, technical solution and beneficial effects of the present invention clearer, the preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings to facilitate understanding by technicians.

[0021] The utility model discloses a predatory mite breeding material heating blast drying box, the predatory mite breeding material heating blast drying box mainly comprises a box body 1, an air guide mesh plate 2, a partition 3, a hot air blower 4, an exhaust fan 5, a movable storage rack 6, a storage tray 7, a controller 8, a heat preservation box 9, a hot air cavity 10, a connecting pipe 11, a box door 12, a fixing seat 13, and an air inlet pipe 14. The box body 1 is hinged with a box door 12 on the side, and a heat preservation box 9 is installed inside the box body 1. The two sides of the heat preservation box 9 are respectively separated by the air guide mesh plate 2 to form a hot air cavity 10, and the top of the air guide mesh plate 2 is provided with a heat preservation box 9. A partition 3 is installed, and hot air blowers 4 are installed on the left and right sides of the top of the partition 3. The air inlet of the hot air blower 4 is connected to the inside of the insulation box 9, and the air outlet of the hot air blower 4 is connected to the hot air chamber 10. The exhaust fan 5 is installed on the top of the box body 1 through a fixed seat 13, and the air inlet of the exhaust fan 5 is connected to the inside of the insulation box 9 through a connecting pipe 11. The top of the box body 1 is provided with an air inlet pipe 14 connected to the inside of the insulation box 9. The controller 8 is installed on the side wall of the box body 1, and the hot air blower 4 and the exhaust fan 5 are electrically connected to the controller 8 respectively; a movable storage rack 6 for placing a storage tray 7 is installed inside the insulation box 9.

[0022] When in use, the operator places the storage trays 7 containing the predatory mite breeding materials on the mobile storage rack 6 in sequence. After placement is completed, the box door 12 is closed, and the hot air blower 4 and the exhaust fan 5 are started in sequence. The hot air blower 4 draws air in the insulation box 9 for heating. The hot air formed after heating is blown into the hot air cavity 10 through the air outlet of the hot air blower 4, and then flows into the insulation box 9 through the mesh holes of the air guide mesh plate 2, thereby heating and drying the breeding materials in the storage tray 7, which can accelerate the air circulation in the insulation box 9 and make the temperature distribution in the insulation box 9 more uniform. The mobile storage rack 6 is conducive to the circulation of hot air, ensuring that each layer of the storage tray 7 is covered with hot air, thereby improving the drying effect of the breeding materials. At the same time, the water vapor generated by the breeding materials during the drying process is sucked and quickly discharged through the exhaust fan 5, reducing the water vapor content in the insulation box 9, thereby accelerating the drying speed of the breeding materials and further improving the work efficiency. A part of the hot air in the insulation box 9 is sucked by the hot air blower 4 for recycling, saving energy.

[0023] Two guide plates 16 are provided at the air outlet of the hot air blower 4 , and an air guide channel 17 is formed between the guide plates 16 and the partition plate 3 and the inner wall of the insulation box 9 ; the air guide channel 17 is used to guide the hot air at the air outlet of the hot air blower 4 into the hot air cavity 10 .

[0024] A temperature sensor 15 is installed on the partition 3, and the temperature sensor 15 is electrically connected to the controller 8; the temperature in the insulation box 9 is monitored in real time by the temperature sensor 15, and the heating temperature of the hot air blower 4 is adjusted by the controller 8 to ensure that the drying temperature in the insulation box 9 is constant.

[0025] The mobile storage rack 6 includes a rectangular frame base 601, a column 602, a support rod 603, a limit rod 604, and a brake wheel 605. Two parallel U-shaped guide grooves 901 are opened at the bottom of the box body 1. The four corners of the rectangular frame base 601 are equipped with brake wheels 605, and the brake wheels 605 are all located in the U-shaped guide grooves 901. The four corners of the rectangular frame base 601 are equipped with columns 602, and multiple support rods 603 are installed on the columns 602 at equal intervals. 3. A plurality of limit rods 604 for limiting the placement tray 7 are installed at equal intervals between the support rods 603. When in use, the operator fills the placement tray 7 with the predatory mite breeding material on the movable placement rack 6, and then pushes the movable placement rack 6 into the insulation box 9 along the U-shaped guide groove 901, and fixes the foot brake wheel 605 by the foot brake. The movable placement rack 6 is conducive to the circulation of hot air, ensuring that each layer of the placement tray is covered with hot air, thereby improving the drying effect of the breeding material.

[0026] The top edge of the storage tray 7 is provided with a limit block 701 overlapped with the support rod 603 or the limit rod 604, and the limit block 701 is provided with a handle 702 for easy transportation of the storage tray 7; when the operator places the storage tray 7, the support rod 603 or the limit rod 604 is used to limit the limit block 701 on the storage tray 7, which can improve the stability of the storage tray 7 after placement.

[0027] A detachable sponge filter 18 is provided on the partition 3, and the sponge filter 18 is located at the air inlet of the hot air blower 4; the sponge filter 18 has good moisture absorption performance, can filter moisture in the hot air, effectively absorb water vapor in the hot air, and ensure that the sponge filter 18 is clean and dry through regular manual inspection and replacement.

[0028] Working process:

[0029] When in use, the operator fills the storage tray 7 with the predatory mite breeding material on the movable storage rack 6, then pushes the movable storage rack 6 into the heat preservation box 9 along the U-shaped guide groove 901, fixes the foot brake wheel 605 by the foot brake, and then closes the box door 12, and starts the hot air blower 4 and the exhaust fan 5 in turn. The hot air blower 4 draws air in the heat preservation box 9 for heating, and the hot air formed after heating is blown into the hot air cavity 10 through the air outlet of the hot air blower 4, and then circulates to the inside of the heat preservation box 9 through the mesh holes of the air guide mesh plate 2, so as to heat and dry the breeding material in the storage tray 7, which can accelerate the air circulation in the heat preservation box 9 and make the temperature distribution in the heat preservation box 9 more uniform. The movable storage rack 6 is conducive to the circulation of hot air, ensuring that each layer of the storage tray 7 is covered with hot air, thereby improving the drying effect of the aquaculture material. At the same time, the water vapor generated by the aquaculture material during the drying process is sucked out by the exhaust fan 5 and quickly discharged, reducing the water vapor content inside the insulated box 9, thereby accelerating the drying speed of the aquaculture material and further improving the work efficiency. A part of the hot air in the insulated box 9 is sucked out by the hot air blower 4 for recycling, saving energy; the temperature in the insulated box 9 is monitored in real time by the temperature sensor 15, and the heating temperature of the hot air blower 4 is adjusted by the controller 8 to ensure that the drying temperature in the insulated box 9 is constant.
