Description

A high-efficiency dehydration and drying equipment for clean vegetables Technical Field

[0001] This utility model relates to the field of food processing, specifically to a high-efficiency dehydration and drying device for clean vegetables. Background Technology

[0002] Cleaned vegetables refer to vegetables or fruits that have been washed, cut, sorted, and packaged and are ready to be used directly for cooking. They save consumers the troublesome steps of processing them themselves, saving time and reducing kitchen waste. Inedible parts such as vegetable roots, yellow leaves, and fruit peels have been removed. After washing and disinfection, some products are cut into the required shapes, such as shreds, chunks, and cubes, thus making them ready to use.

[0003] Common categories include leafy greens (spinach, lettuce), pre-cut side dishes (shredded carrots, diced onions), mixed salads, and hot pot platters. In the processing of pre-cut vegetables, dehydration and drying are two key preservation techniques, primarily used to extend shelf life, reduce microbial growth, maintain texture, or facilitate subsequent processing, such as ready-to-eat salads and dehydrated vegetable snacks.

[0004] Dehydration removes free moisture from the surface of vegetables, preventing microbial growth or spoilage during transport due to residual water. Using hot air drying or vacuum drying can further remove internal moisture, allowing for long-term storage at room temperature.

[0005] Most existing dehydration equipment uses centrifugal force to dehydrate cleaned vegetables. However, centrifugal dehydration alone can cause the cleaned vegetables to accumulate at the bottom of the filter cartridge, resulting in low dehydration efficiency and poor effect. On the other hand, if centrifugal dehydration is not performed and air drying is used alone, the drying time will be too long, which will affect the dehydration efficiency. Summary of the Invention

[0006] To address the problem that most existing dehydration equipment uses centrifugal force to dehydrate clean vegetables, but centrifugal dehydration alone leads to the accumulation of clean vegetables at the bottom of the filter cartridge, resulting in low dehydration efficiency and poor effect, and that simply using air drying without centrifugal dehydration results in a long drying time, affecting dehydration efficiency, this utility model provides a high-efficiency dehydration and drying device for clean vegetables.

[0007] A high-efficiency dehydration and drying device for clean vegetables includes a dehydration tank. A set of support plates is fixedly installed on the outer wall of the dehydration tank. A reciprocating screw and a limiting groove are installed on the support plates. A top cover is movably installed on the outer wall of the reciprocating screw and the limiting groove. An air pump is installed on the top wall of the top cover. Several air jet pipes are connected to the air pump. Several conical air jet holes with a wider inner diameter and a narrower outer diameter are provided through the outer wall of the air jet pipes. An inner cylinder is rotatably installed inside the dehydration tank through a connecting structure. A mesh basket is detachably installed inside the inner cylinder. Several drainage holes are provided through the inner cylinder.

[0008] Furthermore, a drain pipe is fixedly installed through the bottom side wall of the dehydration tank. Both the dehydration tank and the inner cylinder are cylindrical structures with open tops. The connecting structure includes a spline shaft fixedly installed on the bottom wall of the dehydration tank, a cylindrical groove fixedly installed on the bottom wall of the inner cylinder, an internal spline fixedly installed on the inner wall of the cylindrical groove, and the spline shaft meshing with the internal spline.

[0009] Furthermore, a rotary bearing is fixedly installed on the inner wall of the dehydration tank, and the other end of the rotary bearing is fixedly connected to the outer wall of the inner cylinder. The inner cylinder can rotate relative to the dehydration tank. Several paired magnet blocks are fixedly installed at corresponding positions on the inner wall of the inner cylinder and the outer wall of the mesh basket.

[0010] Furthermore, a set of support plates are equipped with drive motors via mounting brackets. Reciprocating lead screws and drive gears are fixedly mounted on the output ends of the two drive motors, respectively. A gear ring is fixedly mounted on the outer wall of the top of the inner cylinder, and the gear ring meshes with the drive gear.

[0011] Furthermore, a limiting groove is fixedly provided on the inner wall of another support plate frame opposite to the reciprocating screw. The upper cover includes a top plate and an inner ring. The inner ring is fixedly provided on the bottom wall of the top plate. Moving blocks are fixedly provided on the side walls at both ends of the top plate. One of the moving blocks is threadedly connected to the reciprocating screw, and the other moving block can move up and down in the limiting groove.

[0012] Furthermore, a flow gap is provided between the outer wall of the inner ring and the inner wall of the inner cylinder to facilitate exhaust. The air outlet of the air pump is connected to an exhaust pipe with one inlet and four outlets. The other end of the exhaust pipe is connected to four jet pipes. Conical jet holes are evenly distributed on the outer wall of the four jet pipes, and their structure is a conical structure with a wide inlet end and a narrow outlet end.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: After the chopped vegetables are placed in the mesh basket, they are put into the inner cylinder for dehydration. Before the inner cylinder drives the mesh basket to centrifuge and dehydrate, the top cover is closed, and then the air pump is started. This allows the vegetables to be dehydrated by combining the dehydration with the air sprayed from the conical air nozzle through the air jet pipe. The vegetables are not blown around and will not accumulate at the bottom of the filter cylinder, which can speed up the dehydration efficiency. This allows the centrifugal dehydration and air drying methods to be combined, reducing the drying time and improving the dehydration efficiency. Attached Figure Description

[0025] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments of the present invention can be combined with each other. The present invention will now be described in detail with reference to Figures 1-6 and the embodiments.

[0026] A high-efficiency dehydration and drying device for clean vegetables includes a dehydration tank 1. A set of support plates 2 is fixedly installed on the outer wall of the dehydration tank 1. A reciprocating screw 3 and a limiting groove 4 are installed on the support plates 2. A top cover 5 is movably installed on the outer wall of the reciprocating screw 3 and inside the limiting groove 4. A drive motor 19 is installed on the set of support plates 2 through a mounting bracket. A reciprocating screw 3 and a drive gear 20 are fixedly installed on the output ends of the two drive motors 19, respectively.

[0027] When the drive motor 19 is started, it can drive the reciprocating lead screw 3 and the drive gear 20 to rotate respectively. Since the inner wall of the other support plate frame 2 opposite to the reciprocating lead screw 3 is fixedly provided with a limiting groove 4, the upper cover 5 includes a top plate 22 and an inner ring 23. The inner ring 23 is fixedly provided on the bottom wall of the top plate 22. Movable blocks 26 are fixedly provided on the side walls at both ends of the top plate 22. One of the movable blocks 26 is threadedly connected to the reciprocating lead screw 3, and the other movable block 26 can move up and down in the limiting groove 4.

[0028] The rotation of the reciprocating screw 3 can drive the moving block 26 to move up and down along the limiting groove 4. That is, it drives the top plate 22 and the inner ring 23 to move up and down with the reciprocating screw 3. When the top cover 5 moves to the top of the limiting groove 4, the top of the inner cylinder 9 is exposed, and the mesh basket 10 containing clean vegetables can be easily put into the inner cylinder 9. Since several pairs of magnet blocks 18 are fixedly installed at corresponding positions on the inner wall of the inner cylinder 9 and the outer wall of the mesh basket 10, the paired magnet blocks 18 can fix the mesh basket 10 on the inner cylinder 9 and rotate with the inner cylinder 9.

[0029] Both the dehydration tank 1 and the inner cylinder 9 are cylindrical structures with open tops. When the top cover 5 moves to the bottom of the limiting groove 4, the top cover 5 can just cover the inner cylinder 9 slightly above it, with a certain space gap between it and the side wall and top wall of the inner cylinder 9. A flow gap 24 is provided between the outer wall of the inner ring 23 and the inner wall of the inner cylinder 9 to facilitate exhaust. The flow gap 24 can ensure that it will not affect the rotation of the inner cylinder 9, and the blowing gas sprayed through the jet pipe 7 will eventually be discharged to the outside through the flow gap 24 after passing through the surface of the cleaned vegetables.

[0030] The top wall of the cover 5 is equipped with an air pump 6, and the air pump 6 is connected to several jet pipes 7. Several conical jet holes 12 with a wider inner diameter and a narrower outer diameter are provided through the outer wall of the jet pipes 7. The air outlet end of the air pump 6 is connected to an exhaust pipe 25 with one inlet and four outlets. The other end of the exhaust pipe 25 is connected to the four jet pipes 7. The conical jet holes 12 are evenly distributed on the outer wall of the four jet pipes 7, and their structure is a conical structure with a wider inlet end and a narrower outlet end.

[0031] While the dehydration tank 1 is rotating and dehydrating, the air pump 6 is started. The air pump 6 is a blower pump 6 in the prior art, and its air inlet port can be connected to the air outlet of the hot air blower, so that the air pump 6 can blow out hot air for drying. The air blown out by the air pump 6 enters from the air inlet of the exhaust pipe 25, is dispersed to the four air outlets, and then is sprayed out through the four jet pipes 7, and finally sprayed out from the conical jet hole 12. It can be sprayed onto the surface of the cleaned vegetables, blow away the cleaned vegetables that have been piled up at the bottom of the grid basket 10 due to centrifugal force, reduce the pile-up, and blow off the moisture on the surface of the cleaned vegetables. Combined with centrifugal dehydration, it can speed up the dehydration efficiency. If hot air is blown, it can dry faster. The conical jet hole 12 has a conical structure with a wide air inlet and a narrow air outlet, which can better prevent the cleaned vegetables from entering the inside of the jet pipe 7 through the conical jet hole 12.

[0032] The dehydration tank 1 has an inner cylinder 9 rotatably mounted inside via a connecting structure 8. The connecting structure 8 includes a spline shaft 14 fixedly mounted on the bottom wall of the dehydration tank 1. A cylindrical groove 15 is fixedly mounted on the bottom wall of the inner cylinder 9. An inner spline 16 is fixedly mounted on the inner wall of the cylindrical groove 15. The spline shaft 14 and the inner spline 16 are meshed and connected.

[0033] When the inner cylinder 9 rotates, it can drive the cylindrical groove 15 to rotate, which in turn drives the inner spline 16 to rotate along the outer wall of the spline shaft 14. Since the spline shaft 14 and the inner spline 16 are meshed and connected, the inner cylinder 9 can rotate relative to the dehydration tank 1.

[0034] A rotary bearing 17 is fixedly installed on the inner wall of the dehydration tank 1. The other end of the rotary bearing 17 is fixedly connected to the outer wall of the inner cylinder 9. The inner cylinder 9 can rotate relative to the dehydration tank 1. The rotary bearing 17 can make the rotation of the inner cylinder 9 more stable and reduce shaking. A gear ring 21 is fixedly installed on the outer wall of the top of the inner cylinder 9. The gear ring 21 is meshed with the drive gear 20. When the drive motor 19 is started, the drive gear 20 can be driven to rotate, which means that the gear ring 21 can be driven to rotate. Since the gear ring 21 is fixedly installed on the outer wall of the top of the inner cylinder 9, it drives the inner cylinder 9 to rotate.

[0035] The inner cylinder 9 is detachably equipped with a mesh basket 10. Rotating the inner cylinder 9 can drive the mesh basket 10 to rotate, so that the clean vegetables inside can be centrifuged and dehydrated. Several drain holes 11 are provided through the inner cylinder 9. The water dehydrated from the mesh basket 10 falls into the bottom of the inner cylinder 9 and is discharged into the dehydration box 1 along the drain holes 11. Since a drain pipe 13 is fixedly installed through the bottom side wall of the dehydration box 1, the dehydrated water is finally discharged to the outside through the drain pipe 13.

[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
