The end of the lead screw 25 away from the driven bevel gear 24 is fixedly connected to a limit plate. 26. The limiting plate 26 is used to limit the lead screw 25, so that the lead screw 25 can only rotate in place. A movable block 27 is movably connected to the surface of the lead screw 25. The movable block 27 is used to drive the connecting block 28, the second support plate 211, and the fan 212 to move, thereby adjusting the height of the fan 212, which is convenient for the staff to adjust the height of the fan 212, and thus convenient to adjust the wind speed of drying food.

The limiting and fixing mechanism is provided. A connecting plate 33 is fixedly connected to the surface of the return spring 32. The connecting plate 33 is used to connect the return spring 32, the pin 34 and the pull rod 35. It is also used to squeeze the return spring 32, causing the return spring 32 to deform. A pin 34 is fixedly connected to the side of the connecting plate 33 away from the return spring 32. The pin 34 is used to insert into the scraper 3, thereby limiting and fixing the scraper 3. A pull rod 35 is fixedly connected to the side of the connecting plate 33 away from the pin 34. The pull rod 35 is used to pull the pin 34 away from the scraper 3, so that the scraper 3 can be removed from the first support plate 11, thereby facilitating the replacement of the scraper 3.

[0031] Furthermore, the first column 2 is distributed in two groups on the surface of the first support plate 11. The first column 2 is used to fix the adjustment mechanism on the first support plate 11 and to limit the movement of the moving block 27 so that the moving block 27 will not rotate with the rotation of the lead screw 25. The rotating shaft 21 is cylindrical in shape, and the handwheel 22 is rotatably connected to the first column 2 through the rotating shaft 21. The rotating shaft 21 and the handwheel 22 are used to drive the active bevel gear 23 to rotate.

[0033] Furthermore, the lead screw 25 is rotatably connected to the first column 2 via the driven bevel gear 24. The lead screw 25 is used to drive the moving block 27 to move, thereby driving the connecting block 28 and the second support plate 211 to move. The limiting plate 26 is in the shape of a circular plate. The limiting plate 26 is rotatably connected to the first column 2 via the lead screw 25. The limiting plate 26 is used to limit the lead screw 25, so that the lead screw 25 can only rotate in place.

[0034] Furthermore, both the moving block 27 and the connecting block 28 are block-shaped. The moving block 27 and the connecting block 28 are slidably connected to the first column 2 via the lead screw 25. The moving block 27 is used to drive the connecting block 28, the second support plate 211 and the fan 212 to move, thereby adjusting the height of the fan 212, which is convenient for the staff to adjust the height of the fan 212, and thus convenient to adjust the wind speed of drying food. The connecting block 28 is used to connect the moving block 27 and the second support plate 211. The second columns 29 are distributed in six groups on the surface of the first support plate 11. The second columns 29 and the slider 210 are used to move the other side of the second support plate 211.

[0035] Furthermore, the slider 210 is block-shaped, the second support plate 211 is plate-shaped, and the second support plate 211 is slidably connected to the first column 2 via the connecting block 28. The second support plate 211 is used to support the fan 212, which is used to dry the food. The higher the fan 212 is, the farther away it is from the food, and the lower the air speed for drying the food. The scraper 3 is plate-shaped and is used to scrape off food residue on the conveyor belt 12 to prevent food residue from affecting the use of the dryer. The fixing block 31 is block-shaped and is distributed in two groups on the surface of the first support plate 11. The fixing block 31 is used to fix the limiting mechanism on the first support plate 11 and also to prevent the return spring 32 from vibrating when it is squeezed.

[0036] Furthermore, the two ends of the return spring 32 are fixedly connected to the fixing block 31 and the connecting plate 33 respectively. The return spring 32 is used to push the connecting plate 33 and the pin 34 back to their original positions, so that the pin 34 is inserted into the scraper 3, thereby achieving the limiting and fixing of the scraper 3. The connecting plate 33 is in the shape of a circular plate. The connecting plate 33 is used to connect the return spring 32, the pin 34 and the pull rod 35. At the same time, it is used to squeeze the return spring 32, so that the return spring 32 deforms. The pin 34 is in the shape of a cylinder. The pin 34 is inserted into the scraper 3 through the return spring 32 and the connecting plate 33. The pin 34 is used to insert into the scraper 3, thereby achieving the limiting and fixing of the scraper 3. The pull rod 35 is used to pull the pin 34 away from the scraper 3, so that the scraper 3 can be removed from the first support plate 11, thereby facilitating the replacement of the scraper 3.

[0037] Working principle: Turning the handwheel 22 drives the active bevel gear 23 and the driven bevel gear 24 to rotate, which in turn drives the lead screw 25 to rotate. This controls the moving block 27 to move the second support plate 211 and the fan 212, thereby adjusting the height of the fan 212. This allows the staff to adjust the height of the fan 212, which in turn makes it easier to adjust the wind speed for drying food. The higher the fan 212 is, the farther it is from the food, and the lower the wind speed for drying the food.

[0038] The scraper 3 can scrape off food residue on the conveyor belt 12 to prevent food residue from affecting the use of the dryer. Pulling the lever 35 can cause the pin 34 to disengage from the scraper 3, which can remove the scraper 3 from the first support plate 11, thus facilitating the replacement of the scraper 3.
