Detailed implementation manners

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to Figures 1-6, the present invention provides a technical solution: a running system of a fruit and vegetable dryer, which includes a conveying table 1, a segmented drying chamber, a material guiding component, a peeling component, a heat blocking mechanism and a cooling discharge plate 2. The segmented drying chamber is installed on the conveying table 1 and includes a machine body shell 3, a first partition plate 4, a second partition plate 5, an electric heating plate 6 and an exhaust pipe 7. Two groups of first partition plates 4 and second partition plates 5 are evenly arranged inside the machine body shell 3. The two groups of first partition plates 4 form three drying chambers 8 inside the machine body shell 3. A temperature buffer chamber 9 is formed between two adjacent first partition plates 4 and second partition plates 5. The electric heating plates 6 are divided into three groups and are respectively installed in the three drying chambers 8. The outer sides of the three drying chambers 8 are connected to the exhaust pipe 7. The end of the exhaust pipe 7 is connected to an air extraction pump 10. The material guiding components are divided into three groups and are evenly installed inside the machine body shell 3. The peeling component is installed above the first partition plate 4 and is used in cooperation with the material guiding component. A discharge port 11 is opened at the bottom of the second partition plate 5. The heat blocking mechanism is installed at the discharge port 11. The cooling discharge plate 2 is installed at the end of the conveying table 1;

[0028] The material guiding component includes a conveyor 12 installed obliquely on the right side of the first partition plate 4 and a stepped blanking plate 13 installed on the left side of the first partition plate 4. The stepped blanking plate 13 is composed of several groups of first slope plates 15 and second slope plates 16. The first slope plate 15 is located above the second slope plate 16. The length of the first slope plate 15 is less than the length of the second slope plate 16. A discharge port 17 is opened at the end of the second slope plate 16. Several groups of rollers 18 are installed on both the first slope plate 15 and the second slope plate 16. The falling fruits and vegetables can fall onto the stepped blanking plate 13, guide the fruits and vegetables, and can turn over the materials during the guiding process, which is convenient for better subsequent drying treatment;

[0029] The stripping component includes a shovel plate 19, a slider 20, a guide plate 21, a push rod 22, a magnetic suction block 23, an electromagnetic suction block 24, a power supply box 25, a controller 26 and an infrared sensor 27. The shovel plate 19 is arranged obliquely above the first partition plate 4 and its upper end is connected to the slider 20. The slider 20 slides through the guide plate 21, and the guide plate 21 is installed on the inner wall of the drying chamber 8. One end of the push rod 22 is connected to the slider 20 and the other end is connected to the magnetic suction block 23. The electromagnetic suction block 24 is located on the right side of the magnetic suction block 23 and a return spring 28 is connected between the two. The electromagnetic suction block 24 is connected to the power supply box 25 through a circuit, the power supply box 25 is connected to the controller 26 through a circuit, the controller 26 is connected to the infrared sensor 27, and the infrared sensor 27 is installed below the shovel plate 19. The fruits and vegetables are lifted by the conveyor 12 and moved to the top of the conveyor 12, sensed by the infrared sensor 27 and the signal is transmitted to the controller 26. The controller 26 controls the power supply box 25 to energize the electromagnetic suction block 24. When the electromagnetic suction block 24 is energized, it generates magnetism and pushes the magnetic suction block 23 to move to the left through the electromagnetic suction block 24. During the movement of the magnetic suction block 23 to the left, the position of the shovel plate 19 is adjusted. When the shovel plate 19 moves and shovels the fruits and vegetables, the pressure bar 40 is pressed, causing the peeling blade 38 to flip and peel the fruits and vegetables from the conveyor 12;

[0030] The heat insulation mechanism includes a water-cooling cover 29, a water inlet pipe 30, a drain pipe 31, a cold water main pipe 32 and a hot water main pipe 33. The water-cooling cover 29 is built into the discharge port 11. The water inlet pipe 30 and the drain pipe 31 are respectively installed on both sides of the water-cooling cover 29. The upper end of the water inlet pipe 30 is connected to the cold water main pipe 32, and the drain pipe 31 is connected to the hot water main pipe 33. The cold water main pipe 32 and the hot water main pipe 33 are both installed on the top of the machine body shell 3. The hot air flow can be cooled through the water-cooling cover 29 to avoid the hot air flow from flowing between the drying chambers 8, ensuring an obvious temperature difference between the drying chambers 8.

[0031] Further improved, as Figure 2 shown: The cooling discharge plate 2 is obliquely installed at the left end of the conveying table 1 and a cooling channel 34 is formed inside. The front side of the cooling discharge plate 2 is connected to the cold water main pipe 32 through a pipe and the rear side is connected to the hot water main pipe 33 through a pipe, which can cool the dried fruits and vegetables.

[0032] Further improved, as Figure 2 shown: The temperature buffer chamber 9 is smaller in size than the drying chamber 8 and the two are separated by the first partition plate 4. A notch 35 is formed at the upper end of the first partition plate 4 to facilitate material guiding.

[0033] Further improved, as Figure 1As shown: The temperatures of the three groups of electric heating plates 6 decrease from right to left and are respectively connected to independent switches through wires, which can perform targeted drying according to the water content of fruits and vegetables, avoiding the situation that fruits and vegetables are damaged due to overheating when the water content of fruits and vegetables is relatively low.

[0034] Further improved, as Figure 3 shown: The first slope plate 15 slopes downward at 45 degrees, and the second slope plate 16 slopes upward at 45 degrees. An interval groove 36 is formed between the first slope plate 15 and the second slope plate 16. The outer end of the interval groove 36 is smaller than the inner end in size. Such a design can guide the fruits and vegetables, and can turn over the materials during the guiding process, facilitating better subsequent drying treatment.

[0035] Further improved, as Figure 5 shown: The shovel plate 19 includes an L-shaped turning plate 37 and peeling blades 38 movably installed at the bottom of the L-shaped turning plate 37 through hinges. Two groups of pins 39 are symmetrically installed on both sides of the peeling blades 38. The outer ends of the pins 39 are connected to a pressure rod 40. The pressure rod 40 is located below the peeling blades 38. The peeling blades 38 are made of high-temperature resistant materials. When the shovel plate 19 moves and shovels the fruits and vegetables, the pressure rod 40 is pressed, causing the peeling blades 38 to turn over and peel the fruits and vegetables from the conveyor 12.

[0036] Further improved, as Figure 4 shown: When the electromagnetic suction block 24 is energized, the magnetic pole at the left end is the same as the magnetic pole at the right end of the magnetic suction block 23. Such a design can generate magnetism when the electromagnetic suction block 24 is energized, and push the magnetic suction block 23 to move horizontally through the electromagnetic suction block 24, and adjust the position of the shovel plate 19 to achieve the purpose of shoveling fruits and vegetables.

[0037] Specifically, the water-cooling cover 29 includes a hollow cover plate 41 and a number of groups of water guide pipes 42 installed on the hollow cover plate 41. Adjacent two groups of water guide pipes 42 are connected end to end. The hollow cover plate 41 is in an inverted U-shaped structure and is attached to the inside of the discharge port 11. Such a design can guide the cold water along the water guide pipes 42 and cool the heat flow, reducing the temperature influence between the drying chambers 8.

[0038] In use: The present invention conveys fruits and vegetables from the left end to the segmented drying chamber through the conveying table 1, lifts and moves the fruits and vegetables to the top of the conveyor 12 through the conveyor 12, senses through the infrared sensor 27 and transmits the signal to the controller 26. The controller 26 controls the power supply box 25 to energize the electromagnetic suction block 24. When the electromagnetic suction block 24 is energized, it generates magnetism, and the electromagnetic suction block 24 pushes the magnetic suction block 23 to move to the left. During the process of the magnetic suction block 23 moving to the left, the position of the shovel plate 19 is adjusted. When the shovel plate 19 moves and shovels the fruits and vegetables, the pressure lever 40 is pressed, causing the peeling blade 38 to flip and peel the fruits and vegetables from the conveyor 12. The falling fruits and vegetables can fall onto the stepped blanking plate 13 to guide the fruits and vegetables, and the materials can be turned over during the guiding process, facilitating better subsequent drying treatment. The fruits and vegetables enter the temperature buffer chamber 9, are conveyed to the next drying chamber 8, and the above operations are repeated for re-drying treatment until the fruits and vegetables are exported from the segmented drying chamber and enter the cooling discharge plate 2 for treatment. In addition, the water vapor generated during the heating process can be externally extracted by the air extraction pump 10.
