Description

Technical Field

[0001] The invention relates to the technical field of vegetable processing, and in particular to an air peeling machine for dehydrated vegetables. Background Art

[0002] In the process of dehydration and deep processing of agricultural and sideline vegetable products, many products need to be peeled, especially clean peeling methods, such as garlic, onions, potatoes and other products, so as to dry and store them, especially for consumers to eat, they all need clean and hygienic food. At present, the traditional peeling method of dehydrated vegetables is stirring and friction peeling, which usually puts the product in a U-shaped trough about 2 meters long and 0.8 meters high. There are several rotating steel plates in the trough, which forcibly rub and rub the product by rotation to achieve the purpose of peeling. This peeling method also requires a large amount of water as an auxiliary resource for peeling. This peeling method will contaminate the surface of the product with dirt, increase the microbial value of the product, and cannot guarantee the quality of the product. Furthermore, the surface of the product will be damaged or even destroyed, and the destroyed product will be washed away by water, reducing the yield of the product. Some nutrients on the surface of the vegetable itself will be washed away by water at the same time, so that the taste of the vegetable is not guaranteed. Using a large amount of water will waste water resources, and the sewage washed away will cause water pollution to nature and cannot protect the ecological environment.

[0003] After searching, the announcement number CN207370053U discloses an air peeling machine for dehydrated vegetables, which relates to the technical field of deep processing of dehydrated vegetables, including an integral frame, an inlet hopper and an outlet hopper, wherein the inlet hopper and the outlet hopper are arranged on the integral frame, and characterized in that it also includes a conveying device and a peeling device arranged above the conveying device; the peeling device includes an air jet disc, a compressed air inlet pipe and an air transmission motor, wherein the air jet disc is arranged above the conveying device, and the air jet disc is connected to the compressed air inlet pipe through the air transmission motor. The air peeling machine is carried out by air peeling, which will not cause any damage to the product, ensures the intact shape of the product, and improves the yield of the product. The equipment automatically cleans the conveyor belt, saves time, improves work efficiency, and also increases production capacity. It has high peeling efficiency, good product quality, energy saving and environmental protection, and is often suitable for application in the dehydration industry, which is a product with economic benefits, environmental protection and energy saving.

[0004] However, the above-mentioned air peeler still has the following problems: the conveying device of the above-mentioned air peeler causes the vegetables to pass under the jet disc. Since the vegetables cannot be turned over during the conveying process of the conveying device, the bottom of the vegetables cannot be exposed to the jet action of the jet disc, resulting in incomplete and irregular peeling, affecting the peeling effect.

[0017] 1. In the present invention, when potatoes, onions and other vegetables are passed through the rack by the conveying mechanism, they can be scooped up by the guide shovel. Under the inertia of the vegetables when conveyed by the conveying mechanism and the push of the vegetables behind, the vegetables are lifted to a certain height by the guide shovel and then fall down.

Since the rollers rotate intermittently and reciprocate, the turning direction of the rolling vegetables can be continuously adjusted, and the rubbing of the protrusions on the conical surface of the rollers helps to rub off the withered epidermis on the surface of the vegetables until the vegetables fall back on the conveying surface of the conveying mechanism, and then can be fully peeled by the pneumatic mechanism above. Compared with the prior art, the present invention can automatically turn over and rub the vegetables during the conveying process, reduce the operation process, and facilitate air peeling in the air to improve the air peeling efficiency.

[0019] 3.

The relative positions of two adjacent rollers on the roller shaft are different to adjust the gap width formed by the two rollers, and then it can be adjusted according to the general size of vegetables, so as to be suitable for a variety of working environments and improve applicability.

When the turntable 52 rotates to the point where the arc-shaped tooth segment 54 disengages from the smooth rack 72, the smooth rack 72 moves back under the elastic force of the spring 744, and then the smooth rack 72 drives the frame 71 to reciprocate during the rotation of the turntable 52.

[0040] The working principle and use process of the present invention are as follows: when vegetables such as potatoes and onions are passed through the frame 1 by the conveying mechanism, they can be scooped up by the guide shovel 3. Under the inertia of the vegetables when conveyed by the conveying mechanism and the push of the vegetables behind, the vegetables can be lifted up to a certain height through the guide trough 34 separated by the partition bars 35 and then fall from the guide shovel 3;

[0041] The turntable 52 is driven by the speed reducer 51 to rotate continuously, and the eccentric shaft 53 drives the slide 48 to rotate around the center of the turntable 52, and the slide 48 slides back and forth in the rail frame 47, and at the same time, under the sliding limit of the T-shaped slider 42 and the Z-shaped support plate 2, one of the air pipe racks 41 is driven to swing back and forth, and the first gear 46 is meshed with the strip gear racks 44 on both sides, which can drive the other air pipe rack 41 to swing synchronously, and the nozzles 43 on the two air pipe racks 41 swing back and forth to blow compressed air to the vegetables in the rolling state, so as to achieve the purpose of air peeling;

[0042] In the above process, if Figure 4 As shown, the clockwise rotation of the turntable 52 causes the arc-shaped tooth segment 54 on the circumferential surface of the turntable 52 to contact the smooth rack 72, and through the meshing action of the two, the smooth rack 72 can be driven to compress the spring 744 and move to one side under the guidance of the guide rod 742. When the turntable 52 rotates to the arc-shaped tooth segment 54 and disengages from the smooth rack 72, the smooth rack 72 moves back under the elastic force of the spring 744, and then during the rotation of the turntable 52, the smooth rack 72 drives the frame 71 to reciprocate, and the bar-shaped tooth surface 73 at the bottom of the frame 71 meshes with the second gear 65 of the first row of rollers 62 on the fixed plate 61, driving each roller 62 to move synchronously. Since the roller 62 is tilted in the opposite direction relative to the guide shovel 3, and the two adjacent rollers 63 are set in opposite directions, when the vegetables scooped up by the guide shovel 3 fall down and fall between the two adjacent rollers 63, as shown in FIG. Figure 6 As shown, the left roller 63 applies an upward force to the vegetables when rotating, and the right roller 63 applies a downward force to the vegetables when rotating, so that the vegetables can flip over when falling between two adjacent rollers 63, that is, the vegetables gradually roll down in a spiral motion. Since the roller shaft 62 rotates intermittently, the flipping direction of the rolling vegetables can be continuously adjusted, and the rubbing of the protrusions 632 on the conical surface of the roller 63 helps to rub off the withered skin on the surface of the vegetables, until the vegetables fall back on the conveying surface of the conveying mechanism, and then can be fully peeled by the pneumatic mechanism 4 above to improve the air peeling efficiency.

[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
