Description

Technical Field

[0001] The present invention relates to the field of making tiger-skin chicken feet, and specifically to a rehydration and freezing device for making tiger-skin chicken feet. Background Art

[0002] A freezing and rehydration device for making tiger-skin chicken feet is a device that makes tiger-skin chicken feet through freezing and rehydration processes. First, the fried chicken feet are quickly frozen in a low-temperature environment below -30°C, causing the epidermis to shrink due to the low temperature to form tiger-skin-like wrinkles. This process is called freezing shrinkage. Then, the frozen chicken feet are soaked in warm water at 40 to 60°C, and through water absorption and expansion to soften, collagen is dissolved out, so that the taste of the chicken feet becomes soft and glutinous. This process is called rehydration softening. The entire device controls the temperature and time of freezing and rehydration to ensure that the chicken feet achieve an ideal tiger-skin appearance and soft and glutinous taste.

[0003] Chinese Patent with publication number CN214371134U discloses an environment-friendly liquid nitrogen quick-freezing machine, including a machine body. A support plate is arranged inside the machine body, a loading plate is arranged on the support plate, and a nozzle is arranged on the inner wall of the machine body. The machine body is divided into three cavities by the support plate, and each cavity is correspondingly provided with a secondary sealing door. When it is necessary to take out or store the materials in a certain cavity, the secondary sealing door corresponding to the cavity can be opened, avoiding the complete opening of the machine body, reducing the leakage of liquid nitrogen, and improving the environmental protection effect.

[0004] When the liquid nitrogen quick-freezing machine of the above patent quick-freezes the internal products, it is necessary to place the items layer by layer on the loading plate, which is time-consuming and laborious. And when placing layer by layer and performing subsequent quick-freezing, the materials at the middle position on the upper end of the loading plate cannot be quickly frozen like the materials at the peripheral edge of the loading plate that are closer to the nozzle, and the quick-freezing effect at the middle position is poor. Summary of the Invention

[0005] The purpose of the present invention is to provide a rehydration and freezing device for making tiger-skin chicken feet. By driving the support rod to drive the externally spiraling placement piece to rotate, and when the placement piece rotates, the placement piece moves longitudinally downward through the contraction of the hydraulic rod, so that the feeding piece can drive the chicken feet to be gradually laid flat on the surface of the spiral placement piece, facilitating the laying flat of the chicken feet. And because the spiral placement piece is closer to the first extension pipe at the middle position and the second extension pipe at the edge position, the quick-freezing effect and efficiency can be improved, solving the problems raised in the above background art.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: A rehydration and freezing device for making tiger skin chicken feet, comprising a chassis, a second processing barrel and a first processing barrel are respectively provided on both sides of the upper end of the chassis, a top plate is provided on the upper ends of the first processing barrel and the second processing barrel, a connecting piece is provided at the lower end of the top plate, a support rod is provided at the lower end of the connecting piece, a placing piece is provided around the support rod, a first through hole is provided inside the placing piece, a protruding second limiting piece is provided at the edge of the placing piece, and protruding first limiting pieces are evenly provided on the surface of the placing piece along the spiral trajectory of the placing piece, a bracket is welded on the outer wall of the first processing barrel, when the chicken feet are placed and spread flat on the surface of the placing piece, after the feed piece is placed on the surface of the placing piece at a corresponding height through the bracket, the placing piece can be rotated and moved downward longitudinally at a uniform speed to achieve uniform laying of the material on the surface of the placing piece.

[0007] Preferably, an input piece is rotatably provided at the upper end of the outer portion of the bracket, and an extension piece is welded to one end of the input piece facing the storage piece. The extension piece is placed on the surface of the second limiting piece that is spirally arranged around the storage piece, and the second limiting piece is used to prevent the storage piece from falling off.

[0008] Preferably, the support rod is embedded in the connecting piece and is rotatably connected to the center position of the connecting piece. A first gear is welded on the upper end of the support rod, and a second gear is meshingly connected on one side of the outside of the first gear. Through the output of the second gear position, the storage plate for placing chicken feet at the lower end can be rotated to complete comprehensive soaking and quick freezing.

[0009] Preferably, hydraulic rods are provided on both sides of the lower end of the top plate toward the upper end of the chassis, and the two ends of the hydraulic rods are respectively welded and fixed to the top plate and the chassis. The horizontal height of the top plate can be adjusted by the extension and retraction of the hydraulic rods, and the change in the horizontal height of the top plate can adjust the height of the storage plate.

[0010] Preferably, the height of the first limiting piece is lower than that of the second limiting piece, so as to avoid the first limiting piece and the second limiting piece of the same height affecting the placement of the extension piece and to avoid the higher first limiting piece affecting the sliding of the extension piece.

[0011] Preferably, a first extension tube is provided in the middle position inside the first processing barrel and the second processing barrel, and a hollow structure is recessed inside the support rod toward the first extension tube. A second through hole is provided around the hollow structure of the support rod. The reserved hollow structure facilitates the insertion of the first extension tube, facilitates the subsequent spraying of liquid nitrogen material from the second through hole position, and also facilitates the subsequent extraction of warm water from the support rod position.

[0012] Preferably, second extension pipes are provided at the four corners inside the first processing barrel and the second processing barrel. Through the second extension pipes, liquid nitrogen can be ejected inside the first processing barrel, while the second extension pipes inside the second processing barrel can discharge warm water.

[0013] Preferably, connecting pipes are arranged in a surrounding manner between the lower ends of the first processing barrel and the second processing barrel and the chassis. The connecting pipe at the lower end of the first processing barrel is hermetically connected to both the first extension pipe and the second extension pipe inside the first processing barrel. The first extension pipe and the second extension pipe inside the first processing barrel are connected simultaneously, so that nitrogen can be discharged from both the first extension pipe and the second extension pipe positions at the same time, improving the quick-freezing effect of chicken feet.

A water tank is arranged at the rear end of the second processing barrel, and a second water pump is arranged at the front end of the second processing barrel. Moreover, the first extension pipe, the second water pump and the water tank are hermetically connected. After the second extension pipes are independently connected through the connecting pipes, the warm water inside the water tank can flow in from the positions of the second extension pipes, and the warm water entering the second processing barrel can be discharged from the positions of the first extension pipes.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] When the chicken feet of the present invention are placed and sequentially fed into the first processing barrel and the second processing barrel, the chicken feet are placed around and spirally around the placing pieces around the support rod. And during the placing process, the feeding pieces connected to the placing pieces do not need to adjust their positions. Only the placing pieces need to rotate and longitudinally move during the rotation process. It is not necessary to place the chicken feet layer by layer or adjust the connection positions of the feeding pieces and the placing pieces layer by layer, which is convenient for the user. Moreover, during the placing process of the chicken feet, the placing pieces will rotate through the output at the position of the second gear. The rotation will actively make the chicken feet lie flat on the surface of the placing pieces. And there are protruding sheet-shaped first limiting pieces on the surface of the placing pieces to limit the chicken feet, preventing the chicken feet from slipping and falling off. Finally, since the chicken feet are spirally placed around the support rod and laid flat, when liquid nitrogen is ejected and contacts the claws, the liquid nitrogen can be discharged from both the second extension pipe and the first extension pipe at the same time, contacting the spirally placed chicken feet from the inside to the outside at the same time, truly realizing the simultaneous quick-freezing of the chicken feet, improving the quick-freezing effect and reducing the time required for the quick-freezing process.

Detailed implementation manners

[0027] The present invention will be further described below in conjunction with specific embodiments.

[0028] As Figure 1 shown, a rehydration and freezing device for making tiger skin chicken feet in this embodiment includes a chassis 1. A second processing barrel 5 is arranged on one side of the upper end of the chassis 1, and a first processing barrel 4 is arranged on the other side of the upper end of the chassis 1. The deep-fried chicken feet are sequentially placed inside the first processing barrel 4 and the second processing barrel 5 for processing, being quickly frozen inside the first processing barrel 4, and the quickly frozen chicken feet are soaked in warm water inside the second processing barrel 5;

[0029] Among them, in order to facilitate the placement of chicken feet and the quick freezing and warm water soaking of the chicken feet after placement, a top plate 3 is horizontally provided at the upper end of the first processing barrel 4 and the second processing barrel 5, and a connecting piece 6 is provided at the lower end of the outer portion of the top plate 3. A support rod 24 is provided at the middle position of the lower end of the outer portion of the connecting piece 6, and the support rod 24 is embedded in the interior of the connecting piece 6 and is rotatably connected to the center position of the connecting piece 6. A storage piece 9 is spirally provided around the support rod 24, and the tiger skin chicken feet will be sequentially laid flat on the surface of the spiral storage piece 9 during the quick freezing and soaking process;

[0030] In order to make the clamping claws on the surface of the storage piece 9 contact the liquid nitrogen efficiently, a first through hole 25 is provided inside the spiral storage piece 9. The first through hole 25 can improve the contact effect of the liquid nitrogen. Figure 8 and Figure 9 As shown, a protruding second limiting piece 27 is provided at the edge of the spiral placement piece 9, and the protruding second limiting piece 27 can prevent the clamping claws placed inside from falling off;

[0031] In order to prevent the chicken claws from sliding downward and stacking due to their weight inside the storage piece 9, the surface of the spiral storage piece 9 is evenly provided with protruding first limiting pieces 26 along the spiral trajectory of the storage piece 9. The height of the protruding first limiting pieces 26 is lower than that of the second limiting pieces 27, so as to avoid the first limiting pieces 26 and the second limiting pieces 27, which are flush with each other, from affecting the support of the feeding piece 10.

[0032] In addition, in order to facilitate the laying of chicken feet and improve the efficiency of chicken feet placement, such as Figure 6 and Figure 7 As shown, the outer wall of the first processing barrel 4 is provided with a bracket 11, and the bracket 11 is welded and fixed to the outer wall of the first processing barrel 4. The upper end of the outer side of the bracket 11 is provided with a feed piece 10, and the feed piece 10 is rotatably connected to the bracket 11. The feed piece 10 can be rotated and leaned against the inside of the placement piece 9. The chicken claws fed into the upper end of the placement piece 9 will be stably fed into the placement piece 9 by the feed piece 10.

[0033] An extension piece 28 is provided at one end of the feed piece 10 facing the storage piece 9, and the extension piece 28 is welded and fixed to the feed piece 10. The additional extension piece 28 allows the feed piece 10 to be placed inside the storage piece 9 that rotates and moves longitudinally downward, making it easier to set up and connect the feed piece 10.

[0034] In order to frequently adjust the feeding piece 10 and improve the placement effect of the chicken feet, a first gear 21 is provided at the upper end of the support rod 24, and the first gear 21 is welded and fixed to the support rod 24. A second gear 30 is provided on one side of the outside of the first gear 21, and the outside of the second gear 30 is meshed and connected with the outer wall of the first gear 21. By driving the second gear 30, the support rod 24 and the external placement piece 9 can be driven to rotate through the first gear 21;

[0035] Wherein, hydraulic rods 2 are arranged on both sides of the lower end of the top plate 3 facing the upper end of the chassis 1, and both ends of the hydraulic rods 2 are welded and fixed to the top plate 3 and the chassis 1 respectively. While the placement piece 9 rotates, the hydraulic rods 2 contract, so that without adjusting the position of the feeding piece 10, when the placement piece 9 rotates and moves vertically downward, the feeding piece 10 can transfer the chicken feet layer by layer to the upper end of the placement piece 9 spirally arranged outside the support rod 24. After the placement piece 9 is vertically placed inside the first processing barrel 4, the feeding piece 10 will completely transfer all the chicken feet that can be filled;

[0036] In order to stably insert the placement piece 9 into the first processing barrel 4 and the second processing barrel 5, guide holes 8 are arranged at the four corner positions around the second processing barrel 5 and the first processing barrel 4, as Figure 3 and Figure 4 shown. Guide rods 7 are arranged at the four corner positions of the spirally arranged placement piece 9, and the guide rods 7 are welded and fixed to the lower end of the connecting piece 6. When the placement piece 9 is inserted into the first processing barrel 4 and the second processing barrel 5, the guide rods 7 will be synchronously inserted into the guide holes 8, and the stability of the placement piece 9 during use is improved through the guide holes 8;

[0037] In order to efficiently and comprehensively quick-freeze the liquid nitrogen when it enters the first processing barrel 4, first extension pipes 18 are arranged at the middle positions inside the first processing barrel 4 and the second processing barrel 5. A hollow structure is recessed inside the support rod 24 towards the first extension pipe 18, and the hollow structure penetrates through the lower end of the support rod 24. When the placement piece 9 and the support rod 24 longitudinally move along with the contraction of the hydraulic rod 2, the first extension pipe 18 will be inserted into the support rod 24;

[0038] A second through hole 29 is arranged around the hollow structure of the support rod 24. Through the reserved second through hole 29, the internal liquid nitrogen can contact the external chicken feet, and it is also convenient for the external warm water to pass through the second through hole 29 and be pumped by the second water pump 15 to form a reflux;

[0039] In addition, as Figure 2 shown, second extension pipes 19 are arranged at the four corner positions inside the first processing barrel 4 and the second processing barrel 5. When the liquid nitrogen is transported into the first processing barrel 4, the liquid nitrogen is discharged into the first processing barrel 4 from the positions of the first extension pipe 18 and the second extension pipe 19 at the same time and comprehensively contacts the placement piece 9 and the chicken feet placed on the upper end of the placement piece 9;

[0040] In addition, when warm water is transported into the second processing barrel 5 and water is discharged from the inside of the second processing barrel 5 to form a reflux, when the warm water is transported into the second processing barrel 5, the warm water is discharged from the second extension pipe 19 into the second processing barrel 5. After the warm water contacts the quick-frozen chicken feet, the warm water is discharged from the first extension pipe 18 inside the second processing barrel 5. The liquid inside the second processing barrel 5 flows from the surrounding towards the central position, and the flow trajectory is clear and smooth;

[0041] For the extraction of liquid nitrogen and the transmission of warm water, a connecting pipe 22 is arranged around between the lower ends of the first processing barrel 4 and the second processing barrel 5 and the chassis 1. The connecting pipe 22 at the lower end of the first processing barrel 4 is simultaneously and hermetically connected to the first extension pipe 18 and the second extension pipe 19 inside the first processing barrel 4. Through the simultaneous hermetic connection, liquid nitrogen can be simultaneously transmitted into the first extension pipe 18 and the second extension pipe 19 and discharged simultaneously;

[0042] A liquid nitrogen tank 12 is arranged at the rear end of the first processing barrel 4. A liquid nitrogen transfer pump 13 is arranged between the liquid nitrogen tank 12 and the connecting pipe 22 at the lower end of the first processing barrel 4, and both ends of the liquid nitrogen transfer pump 13 are hermetically connected to the liquid nitrogen tank 12 and the connecting pipe 22 at the lower end of the first processing barrel 4 respectively. Through the liquid nitrogen transfer pump 13, the extraction of liquid nitrogen can be realized. A pipeline for discharging liquid nitrogen is arranged at the upper position of the rear end of the first processing barrel 4. After the first extension pipe 18 and the second extension pipe 19 inside the first processing barrel 4 transport liquid nitrogen into it, the excess liquid nitrogen inside the first processing barrel 4 is discharged from the upper position of the rear end;

[0043] Among them, the connecting pipe 22 at the lower end of the second processing barrel 5 is hermetically connected to the second extension pipe 19 at the four corner positions inside the second processing barrel 5. Through the connecting pipe 22, warm water can be sent into the first processing barrel 4 from the second extension pipe 19. In addition, in order to discharge the liquid inside the first processing barrel 4, a water tank 16 is arranged at the rear end of the second processing barrel 5. As Figure 5 shown, a second water pump 15 is arranged at the front end of the second processing barrel 5, and the first extension pipe 18, the second water pump 15 and the water tank 16 are hermetically connected. The warm water transported into the second processing barrel 5 is extracted by the second water pump 15 and flows back into the water tank 16;

[0044] A first water pump 14 is arranged between the water tank 16 and the second processing barrel 5. The water inlet and the water outlet of the first water pump 14 are hermetically connected to the water tank 16 and the connecting pipe 22 at the lower end of the second processing barrel 5 respectively;

[0045] A heating rod 17 is arranged inside the water tank 16. Through the heating rod 17, the reserved liquid inside the water tank 16 and the liquid flowing back into the water tank 16 can be heated, so that the liquid remains at the required temperature position after contacting the quick-frozen chicken feet;

[0046] In order to adjust the horizontal position of the storage piece 9, a sliding block 23 is provided between the lower end of the top plate 3 and the connecting piece 6, and the sliding block 23 is fixedly welded to the connecting piece 6. The sliding block 23 is embedded inside the top plate 3 and is slidably connected to the inside of the top plate 3. The sliding of the sliding block 23 inside the top plate 3 can adjust the position of the lower storage piece 9, so that the storage piece 9 is placed on the corresponding first processing barrel 4 and second processing barrel 5;

[0047] Among them, a threaded rod 20 for transmission is horizontally arranged inside the top plate 3. The outside of the threaded rod 20 penetrates through the sliding block 23 and is in threaded cooperation with the penetrating position of the sliding block 23. After the threaded rod 20 rotates and drives the threaded rod 20 to rotate, with the cooperation of the thread and the restriction of the top plate 3, the sliding block 23 can slide along the top plate 3.

[0048] Working principle: When using the device to quickly freeze the fried chicken feet, the feeding piece 10 rotates on the bracket 11, and the extension piece 28 at the front end of the feeding piece 10 is placed on the second limiting piece 27 at the edge of the storage piece 9. The chicken feet are sent to the upper end of the storage piece 9 through the feeding piece 10. When feeding the chicken feet, the contraction of the hydraulic rod 2 makes the storage piece 9 move towards the inside of the first processing barrel 4. At the same time, the second gear 30 drives the first gear 21 to rotate through the motor. The rotation of the first gear 21 can drive the storage piece 9 to rotate through the support rod 24, so that the feeding piece 10 is placed on the continuously rotating storage piece 9 that moves towards the inside of the first processing barrel 4. As the storage piece 9 rotates and moves longitudinally, the feeding piece 10 can realize that the chicken feet are completely distributed at different heights inside the storage piece 9 without adjusting the position. After the feeding piece 10 conveys a certain amount of chicken feet, the connecting piece 6 completely covers the upper end outside the first processing barrel 4. The liquid nitrogen delivery pump 13 is started to extract the liquid nitrogen inside the hydraulic rod 2, and the liquid nitrogen is discharged from the positions of the first extension pipe 18 and the second extension pipe 19 inside the first processing barrel 4 at the same time, and at the same time contacts the chicken feet surrounding the outside of the support rod 24. After quick freezing, the hydraulic rod 2 extends, so that the support rod 24 completely extends out of the first processing barrel 4. The threaded rod 20 inside the top plate 3 rotates after being driven by the motor and drives the externally contacted sliding block 23 to slide horizontally, driving the storage piece 9 and the quickly frozen chicken feet on the storage piece 9 to move towards the second processing barrel 5. The contraction of the hydraulic rod 2 makes the storage piece 9 send the quickly frozen chicken feet into the second processing barrel 5. The first water pump 14 extracts the liquid heated by the heating rod 17 inside the water tank 16. The liquid is sent into the second processing barrel 5 from the second extension pipe 19 inside the second processing barrel 5, and is extracted by the second water pump 15 from the first extension pipe 18 inside the second processing barrel 5 and then flows back into the water tank 16 again. After quick freezing, warm water is soaked to realize the rehydration and freezing required for the processing of tiger skin chicken feet.
