[0008] Furthermore, a first motor is fixedly connected to the top side of the top frame at the position corresponding to the connecting shaft, and the output end of the first motor passes through the top frame and is fixedly connected to one end of the connecting shaft.

[0009] Furthermore, each of the driven spur gears meshes with the driving spur gear, and one end of each rotating shaft passes through the top plate and is fixedly connected to the corresponding driven spur gear.

[0010] Furthermore, a sliding groove is provided on the bottom side of the base plate, and connecting rods are symmetrically slidably connected to both ends of the sliding groove.

[0012] The beneficial effects of this utility model are:

[0013] When in use, this food production dryer has the following advantages:

[0014] 1. In this solution, a base, bottom plate, support rod, top plate, reciprocating screw, limit rod, rotating shaft, top frame, connecting shaft, driving spur gear, driven spur gear, sliding block, heating plate, fan, and drying rack are provided. The first motor drives the connecting shaft to rotate, which in turn drives the driving spur gear and reciprocating screw to rotate synchronously. The rotation of the reciprocating screw causes the sliding block to move up and down along the limit rod in the gap between the drying racks, facilitating the adjustment of the positions of several heating plates and fans, improving internal airflow, reducing temperature differences, and preventing uneven drying due to excessive temperature differences between the top and bottom. The rotation of the driving spur gear drives several driven spur gears that mesh with it to rotate synchronously, which in turn causes the rotating shaft to rotate, causing the drying rack to rotate synchronously, improving the drying uniformity of the food on each drying rack and preventing any impact on food quality.

[0015] 2. In this solution, a sliding groove, a bidirectional screw, a connecting rod, a driven bevel gear, a fixed plate, a transmission shaft, a driving bevel gear, a baffle, and a sealing strip are installed. The second motor drives the transmission shaft and the driving bevel gear to rotate, which in turn drives the driven bevel gear and the bidirectional screw to rotate. This, in turn, drives the connecting rods at both ends to move in opposite directions, thereby causing the baffles on both sides to abut against each other and close or open. When closed, drying is convenient. After drying is completed, the baffles move in opposite directions to open, making it easy for staff to remove food from the drying racks. This makes it convenient and quick to pick up and put down food, improving convenience. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-4 As shown, a food production dryer is disclosed, comprising a base 1, a base plate 2 fixedly connected to the upper end of the base 1, support rods 3 symmetrically fixedly connected to both sides of the upper end of the base plate 2, a top plate 4 fixedly connected to the top of the support rods 3, a reciprocating screw 5 rotatably connected to the center of the bottom side of the top plate 4, a sliding block 13 threadedly connected to one end of the reciprocating screw 5, heating plates 14 fixedly connected to all four sides of the outer side of the sliding block 13, and fans 15 fixedly connected to the bottom ends of all four sides of the outer side of the sliding block 13. The heating plates 14 and fans 15 are electrically connected to an external power source. The fans 15 are used to improve internal air circulation and reduce temperature differences between areas. The top side of the top plate 4 is fixedly connected to the bottom of the base 4. A top frame 8 is connected, and a connecting shaft 9 is rotatably connected between the top frame 8 and the top plate 4 at the position corresponding to the reciprocating screw 5. One end of the connecting shaft 9 passes through the top plate 4 and is fixedly connected to one end of the reciprocating screw 5. A driving spur gear 10 is fixedly connected to one end of the connecting shaft 9. Several driven spur gears 11 are rotatably connected at equal intervals on the top side of the top plate 4 at the outer periphery of the driving spur gear 10. A rotating shaft 7 is rotatably connected between the bottom plate 2 and the top plate 4 at the position corresponding to the driven spur gears 11. Several drying racks 16 are fixedly connected at equal intervals on the outer side of the rotating shaft 7. The drying racks 16 have a disc-shaped structure. Baffles 25 are symmetrically arranged on the outer side of the bottom plate 2. Ventilation holes are provided on the top of the top plate 4.

[0025] like Figure 1-4 As shown, a first motor 12 is fixedly connected to the top side of the top frame 8 at the position corresponding to the connecting shaft 9. The output end of the first motor 12 passes through the top frame 8 and is fixedly connected to one end of the connecting shaft 9. The driven spur gears 11 mesh with the driving spur gears 10. One end of the rotating shaft 7 passes through the top plate 4 and is fixedly connected to the corresponding driven spur gear 11. A limit rod 6 is fixedly connected to the bottom of the top plate 4 on one side of the reciprocating screw 5. The sliding block 13 is slidably connected to the limit rod 6. The bottom end of the limit rod 6 is fixedly connected to the bottom plate 2. The bottom end of the reciprocating screw 5 is rotatably connected to the bottom plate 2. The first motor 12 is started. This causes the connecting shaft 9 to rotate, which in turn drives the active spur gear 10 and the reciprocating screw 5 to rotate synchronously. The rotation of the reciprocating screw 5 causes the sliding block 13 to move up and down along the limiting rod 6 in the gap between the drying racks 16, which facilitates the adjustment of the positions of several heating plates 14 and fans 15, improves internal airflow, reduces temperature differences, and avoids uneven drying due to excessive temperature differences between the top and bottom. The rotation of the active spur gear 10 drives several driven spur gears 11 that mesh with it to rotate synchronously, which in turn causes the rotating shaft 7 to rotate, causing the drying racks 16 to rotate synchronously, thus improving the uniformity of drying.

[0026] like Figure 1-4As shown, a groove 17 is provided on the bottom side of the base plate 2. Connecting rods 19 are symmetrically slidably connected to both ends of the groove 17. All connecting rods 19 are L-shaped, and their outer ends are fixedly connected to corresponding baffles 25. The base plate 2 and the top plate 4 are disc-shaped structures with the same diameter. The baffles 25 are arc-shaped structures adapted to the base plate 2 and the top plate 4. Sealing strips 26 are provided at the top, bottom, and sides of the baffles 25 to improve airtightness. An insulation layer is provided on the inner side of each baffle 25 to improve insulation. A bidirectional screw 18 is rotatably connected inside the groove 17. Both ends of the bidirectional screw 18 are threadedly connected to the corresponding connecting rods 19. A driven bevel gear 20 is fixedly connected to the center of the bidirectional screw 18. A fixing plate 21 is fixedly connected to the inner side of the base 1 at the position corresponding to the driven bevel gear 20. A drive shaft 22 is rotatably connected to the upper side of the fixing plate 21 at the position corresponding to the driven bevel gear 20. One end is fixedly connected to a driving bevel gear 23, which meshes with a driven bevel gear 20. A second motor 24 is fixedly connected to the bottom side of the fixed plate 21 at the position corresponding to the transmission shaft 22. The output end of the second motor 24 passes through the fixed plate 21 and is fixedly connected to one end of the transmission shaft 22. The second motor 24 is a forward and reverse motor. When the second motor 24 is started, it drives the transmission shaft 22 and the driving bevel gear 23 to rotate, which in turn drives the driven bevel gear 20 to rotate. As a result, the bidirectional screw 18 rotates, which in turn drives the connecting rods 19 at both ends to move towards each other, which in turn drives the baffles 25 on both sides to move towards each other until they close together and abut against the bottom plate 2 and the top plate 4, forming a relatively sealed space for drying. After drying is completed, the second motor 24 is started in reverse, which similarly drives the connecting rods 19 and the baffles 25 to move in the opposite direction and open, making it easy for staff to remove food from the drying racks 16.

[0027] Working principle: In use, the food to be dried is placed on the drying rack 16. The second motor 24 is started, which drives the transmission shaft 22 and the driving bevel gear 23 to rotate, which in turn drives the driven bevel gear 20 to rotate. This causes the bidirectional screw 18 to rotate, which in turn drives the connecting rods 19 at both ends to move towards each other. This causes the baffles 25 on both sides to move towards each other until they close together and abut against the bottom plate 2 and the top plate 4. When the baffles 25 are closed, drying is facilitated. The first motor 12 is started, which drives the connecting shaft 9 to rotate, which in turn drives the driving spur gear 10 and the reciprocating screw 5 to rotate synchronously. The rotation of the reciprocating screw 5 drives the sliding... Block 13 moves up and down along the limiting rod 6 in the gap between the drying racks 16, which facilitates the adjustment of the positions of several heating plates 14 and fans 15, improves internal airflow, reduces temperature differences, and avoids uneven drying due to excessive temperature differences between the top and bottom. The rotation of the driving spur gear 10 drives several driven spur gears 11 that mesh with it to rotate synchronously, and then the rotating shaft 7 rotates accordingly, causing the drying racks 16 to rotate synchronously, improving the drying uniformity. After drying is completed, the second motor 24 is started in reverse, which in turn drives the connecting rod 19 and the baffle 25 to move and open in the opposite direction, making it easy for staff to remove the food from the drying racks 16.
