Description

TECHNICAL FIELD

[0001] The present application relates to the field of steam peeling technology, and in particular to a steam peeling machine. BACKGROUND

[0002] The steam peeling machine is based on the principle of volume expansion. Under high-temperature steam at high pressure, the water in the material to be peeled becomes pressurized water. When the high-pressure steam is discharged, the pressurized water in the material rapidly evaporates, separating the skin and meat of the material to be peeled, thereby achieving the purpose of peeling.

[0003] The existing steam peeling machine is provided with a steam tank for containing the material. When the material is peeled, the material is loaded into the steam tank, high-temperature steam is introduced into the steam tank, and the steam tank is rotated. After a certain period of time, the gas in the steam tank is discharged, and then the material can be poured out.

[0004] The rotation time of the steam tank is generally set to about 0 seconds (preset time, determined by the steam pressure). During the rotation of the steam tank, a part of the surface of a part of the material abuts against the inner wall of the steam tank. In the case of short rotation time, the displacement and rotation of a single material in the steam tank are limited, resulting in limited contact between the material near the inner wall of the steam tank and the steam, and further resulting in uneven contact between the surface of the material and the steam, and limited peeling effect. However, if the rotation time of the steam tank is prolonged, the volume of the other parts of the material that are steamed and fall off will increase, causing waste of the material. Therefore, a steam peeling machine is needed to improve the uniformity of the contact between the surface of the material and the steam, so as to improve the peeling effect while ensuring that the material has a low loss rate. SUMMARY

[0005] In order to improve the uniformity of the contact between the surface of the material and the steam, so as to improve the peeling effect while ensuring that the material has a low loss rate, the present application provides a steam peeling machine.

[0006] The steam peeling machine provided by the present application adopts the following technical solution:

[0007] The steam peeling machine comprises a frame, a steam tank, a steam pipe and a first driving member; the steam tank is connected to the frame, and the steam tank is provided with a feeding opening and a sealing cover for covering the feeding opening; the steam tank has a second wall and a first wall, an inner wall of the second wall defines a material cavity, the material cavity is communicated with the outside through the feeding opening; the inner wall of the second wall is in an arc shape, an outer wall of the second wall and an inner wall of the first wall define a ventilation cavity, and the ventilation cavity surrounds the material cavity; the first wall is provided with a plurality of through holes; an end of the first wall away from the feeding opening is provided with a waste discharge opening, and the steam tank is provided with a sealing member for covering the waste discharge opening; the steam pipe is communicated with the material cavity, the steam pipe is provided with an air inlet valve and an air outlet valve, the material cavity is communicated with an air inlet device through the air inlet valve, and the material cavity is communicated with an air outlet device through the air outlet valve; and the first driving member is used for driving the second wall to rotate relative to the frame.

[0008] By adopting the technical scheme, when peeling, the sealing cover is opened, the material is added into the material cavity from the feeding opening, then the sealing cover is closed, the first driving member is started, the first driving member drives the second wall to rotate, thereby the material is turned over; meanwhile, the air inlet valve is opened, the steam enters into the material cavity through the steam pipe, a part of the water vapor is liquefied after contacting the material, and the liquid after liquefaction enters into the ventilation cavity through the through holes; after a certain period of time, the waste liquid in the ventilation cavity is discharged through the waste discharge opening which faces downward; then the first driving member is started again, the feeding opening faces downward, and the material is poured out.

[0009] The inner wall of the second wall is arranged in an arc shape, so that the material and the inner wall of the second wall are in point contact with a small contact area; the second wall is provided with a plurality of through holes, so that the steam flows into the ventilation cavity while filling the material cavity, the steam in the ventilation cavity contacts a part of the material surface abutting against the inner wall of the second wall through the through holes, thereby the contact area between the material and the steam is increased in the same time, and the uniformity of the contact between the material surface and the steam is improved. In addition, the liquid after liquefaction of the steam flows in the inner wall of the first wall in the process of rotation of the steam tank, and does not contact the material again, so that the high-temperature water gathered on the material surface in the time period from pouring out of the material to entering of the material into the next process is less, the volume of the material which is heated and cooked is further reduced, and the loss of the material is reduced.

[0010] Optionally, the inner wall of the second wall is provided with a plurality of resistance members which protrude from the inner wall of the second wall, and the resistance members are uniformly distributed on the inner wall of the second wall.

[0011] By adopting the technical scheme, on one hand, the resistance member hinders the material, reduces the risk of the material slipping relative to the second wall due to inertia during acceleration and deceleration of the steam tank, makes the spacing between the materials increase faster, and the spacing can be maintained for a long time, and further improves the uniformity of the material surface and the steam contact; on the other hand, during rotation of the steam tank, the material with a speed relative to the second wall collides with the resistance member protruding from the second wall, and then is turned over under the driving of the resistance member, further improving the uniformity of the material surface and the steam contact.

[0012] Optionally, the second wall comprises a flow guide part and a ventilation part, the feeding port is arranged on the ventilation part, the ventilation part is located between the feeding port and the flow guide part, and the plurality of through holes are distributed on the ventilation part.

[0013] By adopting the technical scheme, on one hand, the through holes are all arranged on the ventilation part, so that the part of the second wall between the ventilation part and the feeding port is relatively smooth, thereby playing a certain flow guiding role when the material is poured out, reducing the risk of the material being stuck in the through holes, and making the material be smoothly poured out; on the other hand, during rotation of the steam tank, when the feeding port faces upward, the liquid water close to the feeding port of the first wall may move centripetally due to its own gravity, or be divided when colliding with the connecting position of the second wall and the first wall, and since the flow guide part is in a solid state, the flow guide part can form a certain block to the liquid water, thereby reducing the risk of the liquid water entering the material cavity from the ventilation cavity.

[0014] Optionally, the exhaust device comprises a muffler and a buffer tank, the muffler is located in the buffer tank, a side wall of the muffler is provided with a plurality of sound reduction holes, and the muffler is in communication with the material cavity through the exhaust valve; the upper part and the lower part of the buffer tank are respectively provided with an exhaust port and a drain valve.

[0015] By adopting the technical scheme, when exhausting, the exhaust valve is opened, the steam enters the buffer tank through the steam pipe, the gas flows into the muffler from the sound reduction holes, and is discharged through the exhaust port; the liquid water formed by the contact with the buffer tank flows out from the drain valve, thereby reducing the exhaust noise and respectively treating the gaseous water and the liquid water.

[0016] Optionally, a surface of the sealing cover facing the material cavity is connected with a first air bag, the first air bag contains alcohol; when the first air bag is full of gas, the first air bag abuts against the edge position of the second wall at the feeding port.

[0017] By adopting the technical scheme, at normal temperature, the alcohol is in a liquid state, after the high-temperature steam is introduced, the alcohol evaporates and expands, the first air bag is lifted up, the first air bag connected to the sealing cover abuts against the second wall, and a certain sealing effect is achieved on the gap between the sealing cover and the first wall, thereby increasing the sealing performance and waterproof performance of the steam tank at the feed inlet.

[0018] Optionally, the feed inlet comprises a first inlet and a second inlet, the first inlet is arranged on the first wall, and the second inlet is arranged on the second wall; the sealing cover comprises a first cover and a second cover, the first cover is arranged on the first wall and is used for covering the first inlet, and the second cover is arranged on the second wall and is used for covering the second inlet; the first wall is rigidly connected to the rack, and the second wall is rotatably connected to the rack; and the diameter of the blowdown outlet is greater than the maximum diameter of the material.

[0019] By adopting the technical scheme, when feeding, the second wall is rotated by the first driving member, so that the second inlet is aligned with the first inlet, then the material is added into the material cavity through the second inlet and the first inlet, and then the first cover and the second cover are closed, the second wall is rotated by the driving member, and then the material cavity is flipped. After peeling is completed, the blowdown outlet is opened, the liquid water in the ventilation cavity and the waste material are discharged; then the first driving member is started, the second wall is flipped, the second inlet faces downward, the second cover is opened, and the material can be poured out from the second inlet and the blowdown outlet. By using the structure, on the one hand, the first driving member only needs to rotate the second wall, and energy consumption is reduced; on the other hand, since the first wall is rigidly connected to the rack, the first wall and the rack are always in a relatively static state, after the liquid water and the waste material enter the ventilation cavity, they slide along the inner wall of the first wall to the blowdown outlet and are accumulated, compared with the case that the first wall rotates, more waste material can be discharged under the action of the liquid water and the gravity of the waste material itself, and the risk that the liquid water in the ventilation cavity enters the material cavity through the through hole can be further reduced.

[0020] Optionally, the first cover is slidably connected to the rack, and the sliding direction of the first cover relative to the rack is along the height direction of the rack; a first connecting member is arranged on the surface of the first cover facing the ventilation cavity, and a second connecting member is arranged on the surface of the second cover facing away from the material cavity; the second connecting member is slidably connected to the first connecting member, and the sliding direction of the second connecting member relative to the first connecting member is along the tangent direction of the rotation of the second wall; and the first connecting member limits the movement of the second connecting member relative to the first connecting member along the central axis direction of the feed inlet.

[0021] By adopting the technical scheme, when the second cover needs to be opened, the first inlet and the second inlet are in coaxial positions, then the first cover is moved upward relative to the first wall through the first connecting piece, and the second cover is moved upward through the second connecting piece in the moving process; and since the second connecting piece is in sliding connection with the first connecting piece, the first connecting piece does not interfere with the second connecting piece and the second wall in the rotating process of the second wall relative to the first wall.

[0022] Optionally, a surface of the second cover facing the material cavity is connected with a first air bag, and the first air bag contains alcohol; when the first air bag is filled with gas, the first air bag abuts against the second wall at the edge position of the feeding port.

[0023] By adopting the technical scheme, after the high-temperature steam is introduced, the first air bag expands and tightly abuts against the inner surface of the second wall, increasing the connection strength of the second cover and the second wall and reducing the risk of centrifugal motion of the second cover in the rotating process of the second wall relative to the first wall.

[0024] Optionally, a plurality of sealing tubes are arranged in the material cavity, the sealing tubes contain alcohol, one end of the sealing tube is connected to the inner wall of the second wall, and the other end of the sealing tube is connected with an agitation ball.

[0025] By adopting the technical scheme, alcohol is easy to volatilize at high temperature, and the sealing tube is lifted after expansion after being heated by the high-temperature steam; in the rotating process of the second wall and the lifting process of the sealing tube, the sealing tube moves relative to the material, so that the sealing tube is used to divide and stir the material, further increasing the contact area and uniformity of the material and the steam; meanwhile, the agitation ball abuts against the material in the overturning process of the material in the material cavity by the second wall, on the one hand, increasing the gap between the adjacent materials near the agitation ball and further increasing the contact uniformity of the material and the steam; on the other hand, since the agitation ball has a connection relationship with the second wall, it is more likely to have a relative motion with the material, so that the material flowing through the agitation ball is divided to a certain extent, increasing the gap between the materials flowing through the agitation ball to facilitate the steam to pass through.

[0026] Optionally, the length of the sealing tube is greater than the distance from the connecting point between the sealing tube and the second wall to the feeding port.

[0027] By adopting the technical scheme, when the sealing cover is opened to pour out the material, the temperature of the sealing tube gradually decreases, so that the volume of the sealing tube gradually decreases, and after the material in the material cavity is completely poured out, the agitation ball falls from the feeding port and hovers below the feeding port under the pulling force of the sealing tube, at this time, the agitation ball can be cleaned to reduce the waste residue on the surface of the agitation ball.

[0028] In summary, the present application includes at least one of the following beneficial technical effects:

[0029] 1. By providing a ventilation cavity outside the material cavity and connecting the two through a through hole, the steam not only contacts the material in the material cavity, but also contacts the material in the ventilation cavity through the through hole, thereby improving the uniformity of the material surface contacting the steam;

[0030] 2. By providing a resistance element on the inner surface of the second wall, the risk of material slipping relative to the second wall during acceleration and deceleration of the second wall is reduced; during rotation of the second wall, the material in contact with the second wall is turned over to some extent, increasing the uniformity of the material contacting the steam;

[0031] 3. By providing a first air bag on the sealing cover, the first air bag contains alcohol, improving the sealing and waterproof properties of the steam tank after steam is introduced. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0045] The following description will be made in conjunction with the Figures 1-12 The application is further described in detail.

[0046] The application discloses a steam peeling machine.

[0047] Embodiment 1

[0048] Referring to the drawings and Figure 2 The steam peeling machine comprises a frame 1, a steam tank 2, a steam pipe 3 and a first driving member 4. The steam tank 2 is connected to the frame 1, and the steam tank 2 is provided with a feeding port 21 and a sealing cover 22 for covering the feeding port 21. The steam tank 2 has a first wall 23 and a second wall 24, and the inner wall of the second wall 24 and the inner wall of the sealing cover 22 define a material cavity 25, which is in communication with the outside through the feeding port 21. The inner wall of the second wall 24 is arc-shaped, and the outer wall of the second wall 24 and the inner wall of the first wall 23 define an air passage cavity 26, which is arranged around the material cavity 25. A plurality of through holes 240 are formed through the second wall 24.

[0049] An end of the first wall 23 away from the feeding port 21 is provided with a blowdown port 231, and the steam tank 2 is provided with a sealing member 230 for covering the blowdown port 231.

[0050] The steam pipe 3 is in communication with the material cavity 25, and the steam pipe 3 is provided with an air inlet valve 31 and an air outlet valve 32. The material cavity 25 is in communication with the air inlet device through the air inlet valve 31 and is in communication with the air outlet device 5 through the air outlet valve 32. The first driving member 4 is used to drive the second wall 24 to rotate relative to the frame 1. In the embodiment, the first driving member 4 is a rotary speed reduction motor, and in other embodiments, a common motor can be connected to the second wall 24 through a speed reduction structure.

[0051] During peeling, the first driving member 4 is used to drive the second wall 24 to rotate, so that the feeding port 21 faces upward; then the material is added into the material cavity 25 from the feeding port 21, and after the feeding is completed, the sealing cover 22 is closed; then the first driving member 4 is used to drive the second wall 24 to rotate again, thereby driving the material in the material cavity 25 to turn over, and at the same time, the air inlet valve 31 is opened, so that high-temperature steam enters the material cavity 25 and the ventilation cavity 26 through the steam pipe 3; the steam in the material cavity 25 contacts the surface of the material, the steam in the ventilation cavity 26 contacts the surface of the material through the through hole 240, and at the same time, the liquid water formed by the steam contacting the material is flowed into the ventilation cavity 26 through the through hole 240; after a certain period of time, the air inlet valve 31 is closed, the air outlet valve 32 is opened, and the steam is discharged into the air outlet device 5; then the sealing member 230 is opened, and the liquid water and waste in the ventilation cavity 26 are discharged; then the first driving member 4 is used to drive the second wall 24 to rotate, so that the feeding port 21 faces downward, the sealing cover 22 is opened, and the material is poured out; finally, the first driving member 4 is used to drive the second wall 24 to rotate, so that the feeding port 21 faces upward, and the above process is repeated to perform the next peeling work.

[0052] In the embodiment, the second wall 24 and the first wall 23 can be integrally formed, can be fixed by welding, can be fixed by clamping, or can be rigidly connected in a detachable manner.

[0053] With reference to Figure 3 and Figure 4 In order to facilitate the manufacture of the steam tank 2, the first wall 23 includes a plurality of first assembly walls 232, and the plurality of first assembly walls 232 abut each other around the central axis of the feeding port 21. The outer surface of the first assembly wall 232 is integrally formed or fixed by welding with a connecting flange 233, and the adjacent connecting flanges 233 are connected to each other by bolts.

[0054] With reference to Figure 4The rubber pads 234 are integrally formed with the insertion strips 235 on the surfaces facing away from each other, and the insertion strips 235 are arranged along the length direction of the rubber pads 234. The two side walls of the first assembly wall 232, which face away from each other, are each provided with an insertion slot 236 for the insertion of the insertion strip 235. Thus, the rubber strip is used to form a seal at the joint between the adjacent first assembly walls 232, so as to ensure the sealing performance and waterproof performance of the first wall 23.

[0055] With reference to Figure 3 and Figure 5 In order to further facilitate manufacturing, the second wall 24 comprises a plurality of second assembly walls 241, which are in one-to-one correspondence with the plurality of first assembly walls 232. The second assembly walls 241 are welded, clamped or integrally formed with the first assembly walls 232. The two side walls of the second assembly wall 241, which face away from each other, are respectively provided with a plurality of insertion holes 242 and a plurality of insertion rods 243. The plurality of insertion rods 243 and the plurality of insertion holes 242 are in one-to-one correspondence and are inserted. The plurality of insertion holes 242 are arranged in a spaced manner along the length direction of the second assembly wall 241, and the insertion rod 243 and the insertion hole 242 are used to establish a connection between the adjacent second assembly walls 241.

[0056] With reference to Figure 5 The periphery of the insertion rod 243 is sleeved with a second air bag 244, and the second air bag 244 is adhesively fixed to the insertion rod 243. The second air bag 244 contains alcohol, which evaporates into gas after the high-temperature steam is introduced. The alcohol gas in the second air bag 244 is used to increase the abutting force between the insertion rod 243 and the hole wall of the insertion hole 242, thereby increasing the friction therebetween and strengthening the connection strength between the adjacent second assembly walls 241 during the peeling process of the second wall 24.

[0057] In the embodiment, the first wall 23 is rigidly connected with the second wall 24.

[0058] With reference to Figure 1 The sealing cover 22 is hingedly connected to the outer wall of the first wall 23. The outer wall of the first wall 23 is connected with a jacking cylinder 27. The sealing cover 22 is connected to the output end of the jacking cylinder 27. The jacking cylinder 27 is used to drive the sealing cover 22 to rotate relative to the first wall 23, so as to realize the opening and closing of the sealing cover 22 by using the cylinder.

[0059] With reference to Figure 2 and Figure 6The surface of the sealing cover 22 facing the material cavity 25 is connected with a first air bag 221, and the first air bag 221 is filled with alcohol. When the high-temperature gas is introduced into the material cavity 25, the alcohol is evaporated to form gas and support the first air bag 221. After the first air bag 221 is supported, the edge abuts the edge position of the second wall 24 at the inlet 21, thereby enhancing the sealing effect of the sealing cover 22.

[0060] The second wall 24 can be formed of a stainless steel mesh, and the mesh holes are the through holes 240. The second wall 24 can also be a stainless steel with punched holes, and the punched holes are the through holes 240.

[0061] In this embodiment, the sealing member 230 is a valve, so that the operation of opening and closing the pollution outlet 231 is more convenient.

[0062] Referring to Figure 2 The steam pipe 3 includes a rotating section 33 and a fixed section 34, and the rotating section 33 is rotationally connected with the fixed section 34 through a rotating joint. The rotating section 33 is fixedly connected with the steam tank 2, and the inlet valve 31 and the outlet valve 32 are both installed on the fixed section 34.

[0063] Referring to Figure 3 The part of the rotating section 33 located in the air cavity 26 is provided with a plurality of air inlet holes 331, so as to facilitate the steam to be introduced into the material cavity 25 and the air cavity 26 at the same time, and improve the uniformity of the contact between the material and the steam.

[0064] Referring to Figure 2 and Figure 3 Further, the inner wall of the second wall 24 is provided with a plurality of resistance members 245, the resistance members 245 protrude from the inner wall of the second wall 24, and the plurality of resistance members 245 are distributed on the inner wall of the second wall 24. By virtue of the design, on the one hand, the resistance members 245 form a certain resistance to the material during the acceleration and deceleration of the second wall 24, thereby reducing the risk of the material slipping relative to the second wall 24 due to its own inertia, so as to ensure the overturning effect of the material; on the other hand, the material with a speed relative to the second wall 24 collides with the resistance members 245 protruding from the second wall 24, and then overturns under the driving of the resistance members 245, thereby further improving the uniformity of the contact between the surface of the material and the steam.

[0065] In this embodiment, the resistance members 245 are made of stainless steel, and the resistance members 245 have a spherical or hemispherical structure, so that the surface of the resistance members 245 has no bending lines or sharp points, thereby reducing the scratching between the material and the resistance members 245. In other embodiments, the surface of the resistance members 245 can also be other curved surfaces, and the resistance members 245 can also be made of other rigid materials.

[0066] The resistance members 245 and the second wall 24 can be fixed by welding, integrally formed, or detachably connected by clamping, bolts, etc.

[0067] With reference to Figure 2 Further, the second wall 24 comprises a flow guiding portion 246 and a ventilation portion 247, the feeding port 21 is located at the ventilation portion 247, the ventilation portion 247 is located between the feeding port 21 and the flow guiding portion 246, and the plurality of through holes 240 are distributed in the ventilation portion 247. That is, a part of the second wall 24 close to the feeding port 21 is solidly arranged without the through holes 240. Thus, on the one hand, the second wall 24 has a relatively smooth flow guiding portion 246, which plays a certain flow guiding role when the material is poured out, reduces the risk of the material being stuck in the through holes 240, and also makes part of the waste in the material cavity 25 flow out together with the material, reducing the waste residue in the material cavity 25; on the other hand, when the feeding port 21 is upward, the liquid water in the ventilation cavity 26 that moves with the first wall 23 may do centripetal motion under the action of its own gravity and the shunting of the sealing cover 22, the solid flow guiding portion 246 forms a certain obstruction to this part of the liquid water, reducing the risk of the liquid water flowing back into the material cavity 25.

[0068] In order to balance the flow guiding effect of the flow guiding portion 246 and the ventilation effect of the ventilation portion 247, the area of the flow guiding portion 246 should not be too large or too small, preferably one third of the area of the entire second wall 24. At the same time, the plane where the edge of the flow guiding portion 246 is located is perpendicular to the central axis of the feeding port 21, so that the movement of each part of the material is relatively symmetrical when pouring.

[0069] With reference to Figure 7 The exhaust device 5 comprises a muffler 51 and a buffer tank 52, the muffler 51 is located in the buffer tank 52, the side wall of the muffler 51 is provided with a plurality of sound holes 511, the muffler 51 is communicated with the fixed section 34 through the exhaust valve 32, and then communicated with the material cavity 25 through the rotating section 33. The upper part and the lower part of the buffer tank 52 are respectively provided with an exhaust port 521 and a drain valve 522. When the exhaust valve 32 is opened, the steam in the steam tank 2 flows into the exhaust device 5 through the exhaust valve 32, then part of the steam enters the muffler from the air hole, and is discharged from the exhaust port 521 after moving upward; another part of the steam is liquefied to form liquid water, which is discharged through the drain valve 522, thereby reducing the noise of the exhaust and separately treating the gaseous water and the liquid water.

[0070] The implementation principle of the embodiment is: in normal state, the feeding port 21 is kept upward; when peeling, the jacking cylinder 27 is started to open the sealing cover 22, the material is added, and then the sealing cover 22 is closed by the jacking cylinder 27; then the first driving member 4 is started to rotate the second wall 24 and the rotating section 33 of the steam pipe 3; at the same time, the air inlet valve 31 is opened to pass in high-temperature steam, the steam enters the material cavity 25 and the air passage 26 through the steam pipe 3, the steam in the material cavity 25 contacts the surface of the material, the steam in the air passage 26 contacts the surface of the material through the through hole 240, and the liquid water flows into the air passage 26 from the through hole 240 and flows on the inner surface of the first wall 23 along with the rotation of the first wall 23;

[0071] After reaching the set time, the blow-off port 231 is made downward, the air inlet valve 31 is closed, the air outlet valve 32 is opened, the steam is discharged from the air outlet 521 of the upper part of the muffler through the air outlet valve 32, and the liquid water in the buffer tank 52 is discharged through the water outlet valve 522; then the sealing member 230 is opened to discharge the liquid water in the air passage 26 and the waste material; then the steam tank 2 is turned over through the first driving member 4 to make the feeding port 21 downward, the sealing cover 22 is opened, and the material is poured out; finally, the steam tank 2 is turned over again through the first driving member 4 to make the feeding port 21 upward, and the next peeling work is performed.

[0072] Embodiment 2

[0073] With reference to Figure 8 The difference between the embodiment and the embodiment is that the first wall 23 and the second wall 24 are separately arranged, the first wall 23 is rigidly connected to the rack 1, and the second wall 24 is rotationally connected to the rack 1. The feeding port 21 includes a first inlet 211 and a second inlet 212, the first inlet 211 is arranged on the first wall 23, and the second inlet 212 is arranged on the second wall 24. The sealing cover 22 includes a first cover 222 and a second cover 223, the first cover 222 is arranged on the first wall 23 and is used for opening and closing the first inlet 211, and the second cover 223 is arranged on the second wall 24 and is used for opening and closing the second inlet 212. The diameter of the blow-off port 231 is greater than the diameter of the material. By virtue of the design, on the one hand, the first driving member 4 only needs to drive the second wall 24 to rotate, thereby reducing energy consumption; on the other hand, since the first wall 23 is rigidly connected to the rack 1, the first wall 23 and the rack 1 are always in a relatively static state during the operation of the peeling machine, compared with the case that the first wall 23 and the second wall 24 rotate together, more waste material in the air passage 26 can be discharged under the action of gravity and the driving of the liquid water, and the risk that the liquid water in the air passage 26 enters the material cavity 25 through the through hole 240 can be further reduced.

[0074] Specifically, the first cover 222 is connected to the rack 1 in a sliding manner, a sliding direction of the first cover 222 relative to the rack 1 is along a height direction of the rack 1, the rack 1 is provided with a second driving member 11 for driving the first cover 222 to slide relative to the rack 1, and the second driving member 11 is a linear driving mechanism such as a pneumatic cylinder, a hydraulic cylinder or a linear motor.

[0075] With reference to Figure 8 and Figure 9 , a surface of the first cover 222 facing the ventilation cavity 26 is provided with a first connecting member 224, and the first connecting member 224 is coaxially arranged with the first inlet 211. An end of the first connecting member 224 away from the first cover 222 is provided with a connecting groove 225, the connecting groove 225 is arranged in an extension direction of a tangent line of the second wall 24, and two ends of the connecting groove 225 respectively penetrate through side walls of the first connecting member 224 away from each other. A surface of the second cover 223 away from the material cavity 25 is provided with a second connecting member 226, the second connecting member 226 is coaxially arranged with the second inlet 212, and an end of the second connecting member 226 away from the second cover 223 is provided with a connecting portion 227. The connecting portion 227 is connected to the connecting groove 225 in a sliding manner along a length direction of the connecting groove 225. During rotation of the first wall 23, the connecting portion 227 passes through the connecting groove 225, so that the first wall 23 and the second wall 24 can be smoothly rotated relative to each other.

[0076] With reference to Figure 9 and Figure 10 , a groove wall of the connecting groove 225 has a projection in the height direction in a horizontal plane, that is, when the connecting portion 227 is located in the connecting groove 225, the groove wall of the connecting groove 225 cooperates with a groove bottom to limit the connecting portion 227 in the height direction of the rack 1. Therefore, when an upward force is applied to the first connecting portion 227 and the first cover 222 and the first connecting portion 227 are moved upward, the second connecting portion 227 and the second cover 223 will be moved upward under the driving of the first connecting portion 227, so as to open the second cover 223 at the same time of opening the first cover 222.

[0077] In order to ensure that the second cover 223 can pass through the first inlet 211, a diameter of the second cover 223 is smaller than that of the first inlet 211.

[0078] In order to further ensure that the second cover 223 can be smoothly moved out of the first inlet 211, a first magnet 228 is embedded at a middle position of a groove bottom of the connecting groove 225, and a second magnet 229 cooperating with the first magnet 228 is embedded at a middle position of the connecting portion 227.

[0079] The first air bag 221 is arranged on the second cover 223, and the inner surface of the second wall 24 is provided with a first flange 248, and a limiting groove for embedding the first air bag 221 is formed between the first flange 248 and the second wall 24. When the first air bag 221 is lifted, the edge of the first air bag 221 is clamped in the limiting groove, so as to enhance the connection strength of the second cover 223 and the second wall 24 during peeling.

[0080] The hole wall of the second inlet 212 is integrally formed with a second flange 249 for abutting against the second cover 223, so as to support the second cover 223.

[0081] It can be understood that, during feeding, the first inlet 211 and the second inlet 212 are coaxial, and in order to avoid that the material falls into the ventilation cavity 26 during feeding, the distance between the edge of the first inlet 211 and the edge of the second inlet 212 is less than the shortest diameter of the material.

[0082] In addition, the blowdown port 231 is used for passing the material, and the sealing element 230 is a cover-shaped structure and is hinged to the first wall 23. The jacking cylinder 27 is arranged below the first wall 23, and is used for driving the sealing element 230 to rotate relative to the first wall 23, so as to open and close the blowdown port 231 by the sealing element 230.

[0083] The implementation principle of the embodiment is that, during peeling, the second inlet 212 and the first inlet 211 are coaxial, the first cover 222 and the first connecting element 224 are moved upward by the second driving element 11, and the first connecting element 224 drives the second connecting element 226 and the second cover 223 to move upward by the cooperation of the connecting groove 225 and the connecting portion 227, so as to open the first inlet 211 and the second inlet 212 and feed the material.

[0084] After feeding is completed, the first inlet 211 and the second inlet 212 are closed, the first driving element 4 is started, the air inlet valve 31 is opened, and the second wall 24 is rotated relative to the rack 1. After a certain period of time, the first inlet 211 and the second inlet 212 are coaxially arranged, the air inlet valve 31 is closed, the air outlet valve 32 is opened, the jacking cylinder 27 is started, and the sealing element 230 is opened to discharge the blowdown; after the blowdown is completed, the second cover 223 is opened, the second wall 24 is rotated, and the material is poured out from the second inlet 212 and the blowdown port 231.

[0085] Embodiment 3

[0086] Reference Figure 11 and Figure 12The embodiment is different from the embodiment 1 in that a plurality of sealed tube bags 28 are arranged in the material cavity 25, and the sealed tube bags 28 are filled with alcohol. One end of the sealed tube bag 28 is connected to the inner wall of the second wall 24, and the other end is connected with the stirring ball 29. Alcohol is easy to evaporate at high temperature, and the sealed tube bag 28 is lifted up by the expansion of the high-temperature steam after heating. In the process of rotating the second wall 24 and lifting up the sealed tube bag 28, the relative movement between the sealed tube bag 28 and the material occurs, so that the sealed tube bag 28 is used to split and stir the material, and the area and uniformity of the contact between the material and the steam are further improved. At the same time, the stirring ball 29 abuts against the material in the process of overturning the material in the material cavity 25 by the second wall 24. On the one hand, the gap between the adjacent materials near the stirring ball 29 is increased, and the uniformity of the contact between the material and the steam is further improved. On the other hand, since the stirring ball 29 has a connection relationship with the second wall 24, it is more likely to have a relative movement with the material, so that the material flowing through the stirring ball 29 will be split to a certain extent, and the gap between the materials flowing through the stirring ball 29 is increased, so that the steam can pass through

[0087] Further, the length of the sealed tube bag 28 is greater than the distance from the connecting point between the sealed tube bag 28 and the second wall 24 to the feeding port 21. When the sealing cover 22 is opened to pour out the material, the temperature near the sealed tube bag 28 gradually decreases, so that the volume in the sealed tube bag 28 gradually decreases. After the material in the material cavity 25 is completely poured out, the stirring ball 29 falls from the feeding port 21 and hovers below the feeding port 21 under the pulling force of the sealed tube bag 28. At this time, the stirring ball 29 can be cleaned to reduce the waste residue on the surface of the stirring ball 29.

[0088] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, any equivalent changes made on the basis of the structure, shape and principle of the present application should be covered within the protection scope of the present application.
