Description

Technical Field

[0001] The present invention relates to the technical field of steam peeling machines, and particularly to a rotary steam peeling machine. Background Art

[0002] In the processing of fruits and vegetables such as potatoes, in order to improve the convenience of subsequent processing, a peeling machine is usually used to peel the fruits and vegetables. Steam peeling is one of the methods of fruit and vegetable peeling. Compared with the traditional chemical agent peeling and grinding wheel peeling methods, it not only has a better peeling effect, but also does not produce drug residues, ensuring the safety of fruit and vegetable processing.

[0003] The existing invention patent with the publication number of CN115568594A discloses a steam peeling machine, which has a high degree of automation, realizes continuous production, reduces labor intensity, improves work efficiency, reduces production costs, and improves product processing performance or quality.

[0004] In the above technical solution, the peeling operation of fruits and vegetables is carried out in a rotating reaction tank. After the fruits and vegetables complete the peeling operation, the peeled fruits and vegetables and the epidermis need to be transported to a sorting device for cleaning and sorting together to obtain clean fruits and vegetables. The operation is relatively cumbersome. At the same time, during the peeling process, the epidermis of the fruits and vegetables will adhere to the inner wall of the reaction tank, which will also reduce the peeling efficiency of the fruits and vegetables. Summary of the Invention

[0005] In view of this, the present invention provides a rotary steam peeling machine, which can separate the fruits and vegetables in the rotating cylinder from the epidermis, ensuring the peeling efficiency of the peeling machine.

[0019] The nylon ropes are fixedly arranged on the side of the bottom plate far from the rotating cylinder.

[0020] More preferably, it further includes a limiting mechanism. A cleaning port is formed on one side of the cleaning tank far from the material receiving pipe. When the material receiving pipe rotates to the lower part of the horizontal plane where the rotation axis of the rotating cylinder is located, the limiting mechanism enables the reciprocating lead screw to rotate synchronously with the rotating cylinder.

[0021] More preferably, a limiting groove is formed on the reciprocating lead screw, and a plurality of the limiting grooves are arranged in a circumferential arrangement with respect to the axis of the reciprocating lead screw;

[0026] More preferably, chamfers are arranged on both sides of the cleaning ring.

[0027] More preferably, it further includes a shielding mechanism. The shielding mechanism includes a retaining ring and a corrugated pipe, wherein,

[0028] The retaining ring is slidably arranged inside the rotating cylinder. There are two retaining rings, which are respectively located at both ends of the peeling plate.

Detailed implementation manners

[0049] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0050] As Figure 1-11As shown in the figure, a rotary steam peeling machine of the present invention includes a frame 1, a rotary drum 2, and a cleaning mechanism 3.

[0051] Among them, the frame 1 is the frame structure of this steam peeling machine, which is used to support and protect other components.

[0052] The rotary drum 2 is used for peeling fruits and vegetables. The rotary drum 2 is rotatably arranged on the frame 1. After steam is input into the rotary drum 2, the surface of the fruits and vegetables in the rotary drum 2 can be steamed. Then, with the reducer driving the rotary drum 2 to rotate, the steamed peel on the surface of the fruits and vegetables can be separated from the fruits and vegetables, achieving the peeling effect. As Figure 1 shown, a cleaning groove 201 is respectively opened at both ends inside the rotary drum 2, where the epidermis removed from the fruits and vegetables can be stored in this cleaning groove 201 to prevent it from hindering the normal progress of the fruit and vegetable peeling operation.

[0053] As a preferred implementation manner, in order to enable fruits and vegetables to enter and exit the rotary drum 2, a receiving pipe 21 communicating with it can be fixedly arranged on the rotary drum 2.

[0054] The cleaning mechanism 3 is used to move the epidermis removed from the fruits and vegetables into the cleaning groove 201. The cleaning mechanism 3 includes a cleaning ring 31 and a driving member 32. The cleaning ring 31 is arranged inside the rotary drum 2 and is slidably connected to it. The driving member 32 is used to drive the cleaning ring 31 to slide. When the driving member 32 drives the cleaning ring 31 to slide, by using the sliding between the cleaning ring 31 and the inner wall of the rotary drum 2, the impurities on the inner wall of the rotary drum 2 can be moved to the cleaning grooves 201 at both ends, thus realizing the separation of the epidermis from the fruits and vegetables. At the same time, the movement of the cleaning ring 31 will also agitate the fruits and vegetables, thereby improving the peeling efficiency of this steam peeling machine.

[0055] As a preferred implementation manner, as Figure 3 shown, the driving member 32 can be set to include a reciprocating lead screw 321 and a reciprocating slider 322. The reciprocating lead screw 321 is rotatably arranged inside the rotary drum 2 and is fixedly connected to the frame 1. The reciprocating slider 322 is sleeved on the reciprocating lead screw 321 and is threadedly connected to it. The cleaning ring 31 is fixedly arranged on the reciprocating slider 322. The reciprocating lead screw 321 and the reciprocating slider 322 are prior arts. That is, when the reciprocating lead screw 321 rotates unidirectionally, the reciprocating slider 322 can be driven to reciprocate. Thus, when the rotary drum 2 rotates unidirectionally, the cleaning ring 31 can be driven to reciprocate inside the rotary drum 2, and the impurities on the inner wall of the rotary drum 2 can be respectively pushed into the two cleaning grooves 201.

[0056] In order to improve the peeling efficiency of the epidermis of the fruits and vegetables inside the rotary drum 2, a peeling plate 5 can also be provided. As Figure 7 and Figure 8As shown, the peeling plate 5 includes a bottom plate 51 and a plurality of nylon ropes 52. The bottom plate 51 is fixedly arranged on one side of the rotating cylinder 2 away from the material receiving pipe 21, and the nylon ropes 52 are fixedly arranged on the side of the bottom plate 51 away from the rotating cylinder 2. By rubbing the surface of fruits and vegetables with the nylon ropes 52, the peeling efficiency of the fruit and vegetable surface can be accelerated. Specifically, the nylon ropes 52 can be arranged in an arc shape, with both ends fixedly connected to the bottom plate 51, and the arc surface is used to scrape the surface of the fruits and vegetables, improving the separation efficiency of the fruit and vegetable surface and the protection effect on the fruits and vegetables. Specifically, chamfers can be arranged on both sides of the cleaning ring 31, as Figure 1 shown. When the cleaning ring 31 slides left and right, the cleaning ring 31 can smoothly contact the peeling plate 5, avoiding damage to the peeling plate 5 caused by the movement of the cleaning ring 31.

[0057] As a preferred embodiment, the frame 1 can be set to include a main body frame 11 and a connecting rod 12. The rotating cylinder 2 is rotatably arranged on the main body frame 11. The connecting rod 12 is fixedly arranged on the main body frame 11 and is connected to the reciprocating lead screw 321 through a limit coupling. The limit coupling can protect the connection between the reciprocating lead screw 321 and the main body frame 11. When the reciprocating lead screw 321 is subjected to a large torque, the reciprocating lead screw 321 can rotate relative to the connecting rod 12, avoiding damage to the reciprocating lead screw 321.

[0058] Furthermore, a limiting mechanism 4 can be provided. A cleaning port 202 is opened on one side of the cleaning groove 201 away from the material receiving pipe 21. The cleaning port 202 is used to discharge impurities in the cleaning groove 201 to the outside of the rotating cylinder 2. When the material receiving pipe 21 rotates to the lower part of the horizontal plane where the rotation axis of the rotating cylinder 2 is located, the limiting mechanism 4 makes the reciprocating lead screw 321 rotate synchronously with the rotating cylinder 2. When the material receiving pipe 21 rotates to the lower part of the horizontal plane where the rotation axis of the rotating cylinder 2 is located, the fruits and vegetables in the rotating cylinder 2 will not contact the peeling plate 5. Therefore, the fruits and vegetables are basically not peeled. At this time, the limiting mechanism 4 makes the reciprocating lead screw 321 rotate synchronously with the rotating cylinder 2, that is, it will not drive the cleaning ring 31 to move. Thus, the cleaning operation of the cleaning ring 31 is not carried out when the peeling efficiency of the fruits and vegetables is low. On the contrary, when the peeling efficiency of the fruits and vegetables is high, the cleaning ring 31 moves to clean the inner wall of the rotating cylinder 2, ensuring the cleaning efficiency of the cleaning mechanism 3 and the separation efficiency of the skin and the fruits and vegetables. At the same time, since the cleaning port 202 is arranged opposite to the material receiving pipe 21, when the cleaning port 202 is located below the horizontal plane where the rotation axis of the rotating cylinder 2 is located, the cleaning ring 31 can move, and the discharge efficiency of impurities in the cleaning groove 201 can be accelerated. At the same time, since the reciprocating lead screw 321 is connected to the connecting rod 12 through a limit coupling, when the reciprocating lead screw 321 rotates synchronously with the rotating cylinder 2, the torque received by the reciprocating lead screw 321 will exceed the limit of the limit coupling. Therefore, the reciprocating lead screw 321 and the connecting rod 12 will rotate, preventing damage to the two.

[0059] As a preferred embodiment, in order to achieve the effect that the limiting mechanism 4 enables the reciprocating lead screw 321 to rotate synchronously with the rotating cylinder 2, a limiting groove 301 can be formed on the reciprocating lead screw 321. A plurality of limiting grooves 301 are arranged in a circumferential arrangement about the axis of the reciprocating lead screw 321. The limiting mechanism 4 is set to include a limiting sleeve 41 and a sliding column 42. The limiting sleeve 41 is fixedly arranged on the rotating cylinder 2 and sleeved outside the reciprocating lead screw 321. A sliding groove 401 is formed in the limiting sleeve 41. The sliding column 42 is slidably arranged in the sliding groove 401 and selectively engaged with one of the limiting grooves 301; as Figure 5 shown, at this time, the material receiving pipe 21 rotates to above the horizontal plane where the rotation axis of the rotating cylinder 2 is located. Affected by gravity, the sliding column 42 will slide into the sliding groove 401 and will not be engaged with the limiting groove 301. As Figure 6 shown, when the material receiving pipe 21 rotates to below the horizontal plane where the rotation axis of the rotating cylinder 2 is located, affected by gravity, the sliding column 42 will slide into the limiting groove 301 and be engaged with it, so that the reciprocating lead screw 321 can be fixedly connected to the limiting sleeve 41, and the reciprocating lead screw 321 can rotate synchronously with the rotating cylinder 2; in order to prevent the sliding column 42 from being disengaged from the limiting groove 301 due to the rotational force during rotation, it is necessary to reduce the length of the sliding column 42 and improve the smoothness of the surface of the sliding column 42.

[0060] In order to prevent impurities in the cleaning groove 201 from returning to the rotating cylinder 2 when the rotating cylinder 2 rotates, a shielding mechanism 6 can be provided. The shielding mechanism 6 includes a retaining ring 61 and a corrugated pipe 62. The retaining ring 61 is slidably arranged inside the rotating cylinder 2. There are two retaining rings 61, which are respectively located at both ends of the peeling plate 5. One corrugated pipe 62 is arranged at one end of each retaining ring 61 away from the peeling plate 5. The corrugated pipe 62 abuts against the retaining ring 61 and the rotating cylinder 2, so that the retaining ring 61 abuts against the peeling plate 5 and seals the cleaning groove 201. Both sides of the cleaning ring 31 are fixedly provided with abutting rods 311 for abutting against the retaining ring 61; as Figure 9 shown, in the natural state, the corrugated pipe 62 abuts against the retaining ring 61 to make it abut against the peeling plate 5 to seal the cleaning groove 201, which can prevent impurities in the cleaning groove 201 from moving into the rotating cylinder 2. When the cleaning ring 31 moves to the position of the retaining ring 61, the abutting rod 311 will abut against the retaining ring 61 to move the impurities in the rotating cylinder 2 into the cleaning groove 201.

[0061] Since there are more impurities in the cleaning groove 201, the cleaning port 202 will be blocked. To avoid this problem, a flushing plate 7 can also be provided. The flushing plate 7 is fixedly arranged in the cleaning groove 201. There are a plurality of flushing plates 7, and the plurality of flushing plates 7 are arranged in a circumferential array about the center line of the rotating cylinder 2. As Figure 11As shown, the flushing plate 7 can not only divide the cleaning tank 201 into multiple connected cavities, accelerating the flow rate of internal impurities, but also change the flow direction of the impurities, thereby flushing the inner wall of the cleaning tank 201, preventing the accumulation of impurities, and accelerating the efficiency of impurity discharge from the rotating drum 2.

[0062] The working principle of a rotary steam peeling machine of the present invention is as follows:

[0063] After fruits and vegetables are added into the rotating drum 2 through the feeding pipe 21, steam is added into the rotating drum 2, and the rotating drum 2 is rotated. By cooperating with the scraping of the peeling plate 5 on the surface of the fruits and vegetables, the surface of the fruits and vegetables can be separated. At the same time, the rotation of the rotating drum 2 can also drive the cleaning ring 31 to slide, thereby moving the surface to the cleaning tank 201, separating it from the fruits and vegetables. This not only eliminates the need for sorting the surface and fruits and vegetables in subsequent processes but also improves the peeling efficiency of the fruits and vegetables.

[0064] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
