[0022] Example

[0023] Please see Figures 1-5 This utility model proposes a technical solution for a low-temperature vegetable dryer: a low-temperature vegetable dryer includes a drying chamber 1 and a vacuum pipe connected to the drying chamber 1. Specifically, the vacuum pipe is connected to a vacuum pump during use. The drying chamber 1 has several trays 2 inside, specifically, a maximum of five trays 2. The bottom sides of each tray 2 are connected to the inner wall of the drying chamber 1 via mounting mechanisms. The mounting mechanisms include a support plate 3, positioning blocks 4, springs 5, and pull plates 6. The support plate 3 is fixedly installed on the bottom of the tray 2. Several mounting blocks 4 are provided on both sides of the inner wall of the drying chamber 1. Matching positioning slots, positioning block 4, and spring 5 are all located inside the support plate 3. Both ends of spring 5 are fixedly connected to the support plate 3 and positioning block 4, respectively. One end of pull plate 6 is fixedly connected to one side of positioning block 4, and the other end of pull plate 6 passes through the support plate 3 and extends to the outside of the support plate 3, with a handle fixedly connected to its end. An opening is provided on the tray 2. Specifically, when disassembling the tray 2, manually pulling the handle moves the fixedly connected positioning block 4 away from the positioning slot, compressing spring 5 and providing support to the support plate 3. When installing the tray 2, the positioning block 4 is moved to the positioning slot. When aligning the same horizontal line, under the action of spring 5, positioning block 4 extends into the interior of positioning groove; the drying oven 1 is also equipped with a flipping mechanism, which includes a rotating rod 7, a support rod 8, a stirring rod 9, a motor 10, and an electric telescopic rod 11. The motor 10 is installed on the top of the drying oven 1, the electric telescopic rod 11 is installed on the drying oven 1 and movably connected to the drying oven 1, the motor 10 and the electric telescopic rod 11 are fixedly connected, the rotating rod 7 is installed inside the drying oven 1, and one top end of the rotating rod 7 is fixedly connected to the output end of the electric telescopic rod 11. Several support rods 8 are provided and symmetrically arranged on the rotating rod 7. On both sides, several stirring rods 9 are provided at the bottom of the support rod 8. One end of the support rod 8 is connected to the rotating rod 7 through a connecting mechanism. Specifically, starting the motor 10 can drive the electric telescopic rod 11, the rotating rod 7, the support rod 8 and the stirring rods 9 to rotate. Starting the electric telescopic rod 11 can drive the rotating rod 7, the support rod 8 and the stirring rods 9 to move up and down. When the stirring rods 9 rotate, they can turn over the material on the tray 2 to realize automated operation and prevent uneven drying. Electric heating tubes 14 are installed on both inner walls of the drying box 1. Specifically, the electric heating tubes 14 adopt existing technology and play a heating role.

[0024] Please see Figure 3As shown, the connecting mechanism further includes a second spring 12 and a locking block 13. A slot is provided at the top end of the support rod 8, and a groove is provided on the rotating rod 7. The second spring 12 and the locking block 13 are both located inside the groove, and the two ends of the second spring 12 are fixedly connected to the groove and the locking block 13 respectively.

[0025] In this embodiment, when the support rod 8 needs to be installed, one end of the support rod 8 is inserted into the groove of the rotating rod 7. Under the action of the spring 12, the locking block 13 can extend into the groove to fix the support rod 8 and prevent the support rod 8 from falling off during movement. When disassembling the support rod 8, simply pull it out.

[0026] Please see Figure 3 As shown, the bottom cross-section of both the card slot and the card block 13 is V-shaped.

[0027] In this embodiment, it is convenient to insert or remove the card block 13.

[0028] Please see Figure 4 As shown, the tray 2 also has several through holes.

[0029] Please see Figure 1 As shown, furthermore, a gear one is fixedly connected to the output end of the motor 10, and a gear two is sleeved on the electric telescopic rod 11, with gear one and gear two meshing.

[0030] In this embodiment, when the motor 10 rotates, it drives the first gear to rotate. Since the first gear meshes with the second gear on the electric telescopic rod 11, the motor 10 drives the electric telescopic rod 11 to rotate when it is working.

[0031] Furthermore, both the positioning block 4 and the positioning groove are rectangular in structure, and there are several springs 5 ​​arranged in a rectangular pattern.

[0032] The working principle of this utility model:

[0033] Vegetables requiring low-temperature drying are placed sequentially onto several trays 2. The trays 2 are then installed onto the drying chamber 1 using an installation mechanism. When the positioning block 4 is moved to the same horizontal line as the positioning groove, it extends into the positioning groove under the action of spring 5, thus securing the tray 2. Next, the support rod 8 is installed onto the rotating rod 7 via a connecting mechanism. One end of the support rod 8 is inserted into the groove of the rotating rod 7. Under the action of spring 12, the locking block 13 extends into the groove, fixing the support rod 8 and preventing it from falling off during movement. The vacuum tube and the vacuum pump input are then connected. Connect the end and start the vacuum pump to evacuate the inside of the drying chamber 1, achieving vacuum drying of the material inside the drying chamber 1. At the same time, the electric heating tube 14 can be activated to heat the inside of the drying chamber 1, improving the drying effect of the material. Start the electric telescopic rod 11 to drive the rotating rod 7, support rod 8 and stirring rod 9 to move downward. When the bottom end of the stirring rod 9 abuts against the tray 2, the stirring rod 9 stops descending. Start the motor 10 to drive the electric telescopic rod 11, rotating rod 7, support rod 8 and stirring rod 9 to rotate. When the stirring rod 9 rotates, it can turn over the material on the tray 2 to achieve automated operation and prevent uneven drying.
