Description

Technical Field

[0001] This invention relates to the field of sauerkraut production technology, and in particular to a pickling and fermentation device for sauerkraut production. Background Technology

[0002] In the production of sauerkraut, brine is used to pickle the sauerkraut to allow it to ferment. At the beginning of the pickling process, the upper layer of vegetables is less compressed by gravity, resulting in slow water seepage, while the lower layer is compressed by the material, leading to a greater amount of water seepage. This results in the lower layer having a lower salinity than the upper layer, creating an uneven salinity. To prevent this, a circulation system is used, typically by connecting a water pump to the top and bottom of the fermentation tank to ensure uniform salt mixing. However, in the middle and later stages of fermentation, when fermentation is complete and a stable high-acid environment has been formed, continuing the circulation system would disrupt the stable anaerobic environment and microbial community. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies where fermentation is completed in the middle and later stages of fermentation, forming a stable high-acid environment, and the use of an up-and-down circulation method would disrupt the stable anaerobic environment and microbial community. Therefore, this invention proposes a pickling and fermentation device for sauerkraut production.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] Design a pickling and fermentation device for sauerkraut production, including a tank body. A water pump for brine circulation is installed on the outer wall of the tank body. The water outlet of the water pump is connected to an annular pipe through a connecting pipe. The annular pipe is installed on the inner wall of the tank body. Multiple through holes are opened at equal intervals around the circumference of the inner wall of the annular pipe near the center. The water inlet of the water pump is connected to a vertical pipe through a guide pipe. The vertical pipe is vertically installed inside the tank body.

[0006] A sealing plug is abutted inside the vertical pipe. The sealing plug is used to change the communication state between the end of the vertical pipe and the connecting pipe. A connecting rod is fixedly connected to the upper end of the sealing plug. The tank body is rotatably connected to a rotating shaft. An elliptical block is fixedly connected to one end of the rotating shaft. When the elliptical block rotates, the position of the connecting rod is changed through the connecting mechanism.

[0007] The upper end of the tank is sealed with a cover.

[0008] Preferably, the water pump is a stainless steel self-priming pump.

[0009] Preferably, the lower end of the vertical pipe is provided with a first filter screen to prevent the vertical pipe from being blocked, and the upper end of the vertical pipe is fixedly connected with a second filter screen, and the connecting rod passes through the second filter screen.

[0010] Preferably, the tank body and the cover body are fixedly connected by bolts.

[0011] Preferably, the connecting mechanism includes a connecting frame, which is fixedly connected to the elliptical block. An elliptical ring is sleeved around the outer periphery of the elliptical block, and an elliptical gap is formed between the elliptical ring and the elliptical block. A movable block for changing the position of the connecting rod is slidably disposed within the elliptical gap, and the movable block is fixedly connected to the connecting rod.

[0012] Preferably, the movable block is provided with a positioning rod, and the positioning rod is fixedly connected to the annular tube.

[0013] Preferably, a rotating block is fixedly connected to the other end of the rotating shaft, a fixing part is fixedly connected to the outer wall of the tank, a sliding groove is provided on the fixing part, the sliding groove has an annular structure, a connecting block is fixedly connected to the rotating block, the connecting block is located in the sliding groove, four slots are provided on the inner wall of the sliding groove, the four slots correspond to the four vertices of the elliptical gap, a locking block is engaged in one of the slots, and the locking block is connected to the rotating block through a triggering mechanism.

[0014] Preferably, the triggering mechanism includes a spring, which is in a stretched state. One end of the spring is fixedly connected to the rotating shaft, and the other end is fixedly connected to the locking block. Limiting grooves are formed on the connecting block and the rotating block, and the locking block is located in the limiting groove.

[0015] Preferably, one end of the card block is fixedly connected to a pressing part, the pressing part has an L-shaped structure, and one end of the pressing part is located on the outer side of the outer peripheral wall of the rotating block.

[0016] Preferably, the sealing plug is made of food-grade silicone rubber material.

[0017] The present invention proposes a pickling and fermentation device for sauerkraut production, which has the following advantages: By connecting the vertex of the minor axis of the elliptical block to the connecting rod, the sealing plug seals the vertical pipe located in the upper part of the guide tube, thereby opening the lower end of the vertical pipe. Water enters from the lower end of the vertical pipe and sprays out from the through hole, thus mixing the liquid in the upper and lower layers of the tank and ensuring the uniformity of salinity. In the middle and later stages, by rotating the elliptical block, the vertex of the major axis of the elliptical block connects to the connecting rod, causing the sealing plug to descend and seal the vertical pipe located in the lower part of the guide tube, opening the upper end of the vertical pipe. The brine in the upper layer is circulated and sprayed onto the vegetables, keeping the upper layer of vegetables moist and in contact with salt, preventing the exposed parts from molding, and avoiding the agitation of the bottom by pumping water from the bottom, thus maintaining the stability of the microbial culture in the middle and lower layers.

Detailed Implementation

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0029] Example 1: Refer to Figure 1-6 A pickling and fermentation device for sauerkraut production includes a tank 3, with a cover 1 sealed to the upper end of the tank 3 by bolts. A one-way valve 2 is connected to the cover 1 to allow the carbon dioxide produced during fermentation to be discharged.

[0030] A water pump 11 for brine circulation is installed on the outer wall of the tank body 3. The outlet end of the water pump 11 is connected to an annular pipe 5 through a connecting pipe 19. The annular pipe 5 is installed on the inner wall of the tank body 3. Multiple through holes 4 are opened at equal intervals around the circumference of the inner wall of the annular pipe 5 near the center. The inlet end of the water pump 11 is connected to a vertical pipe 7 through a guide pipe 10. The vertical pipe 7 is vertically installed inside the tank body 3. The water pump 11 drives the brine in the tank body 3 to circulate, ensuring the uniformity of the brine salinity.

[0031] A sealing plug 12 is abutted inside the vertical pipe 7. The sealing plug 12 is used to change the communication state between the end of the vertical pipe 7 and the connecting pipe 19. A connecting rod 9 is fixedly connected to the upper end of the sealing plug 12. The tank body 3 is rotatably connected to a rotating shaft 6 through a sealing bearing. An elliptical block 8 is fixedly connected to one end of the rotating shaft 6. When the elliptical block 8 rotates, the position of the connecting rod 9 is changed through the connecting mechanism. Initially, by connecting the vertex of the minor axis of the elliptical block 8 to the connecting rod 9, the sealing plug 12 seals the vertical pipe 7 located in the upper part of the connecting pipe 10, thereby making the lower end of the vertical pipe 7 open. Water enters from the lower end of the vertical pipe 7 and flows out from there. The liquid is sprayed out through the through hole 4, thereby mixing the liquid in the upper and lower layers of the tank 3 to ensure the uniformity of salinity. In the middle and later stages, the elliptical block 8 rotates, so that the vertex of the major axis of the elliptical block 8 connects with the connecting rod 9, causing the sealing plug 12 to descend and seal the vertical pipe 7 located at the lower part of the guide pipe 10. This allows the upper end of the vertical pipe 7 to be open, circulating the brine in the upper layer to spray the vegetables, keeping the upper layer of vegetables moist and in contact with salt, preventing the exposed parts from molding, and avoiding the agitation of the bottom by pumping water from the bottom, thus maintaining the stability of the microbial culture in the middle and lower layers.

[0032] Pump 11 is a stainless steel self-priming pump. The stainless steel material can resist salt water corrosion, and the smooth surface is easy to clean.

[0033] The lower end of the vertical pipe 7 is provided with a first filter screen 13 to prevent the vertical pipe 7 from being blocked, and the upper end of the vertical pipe 7 is fixedly connected with a second filter screen 14. The connecting rod 9 passes through the second filter screen 14. The filter screen plays an interception role, which helps to prevent vegetable leaves or sediment from entering the vertical pipe 7.

[0034] Example 2: In Example 1, when the water pump 11 is working, it generates suction on the water in the vertical pipe 7, which causes a force to be exerted on the sealing plug 12, changing the position of the sealing plug 12, such as... Figure 6As shown, the sealing plug 12 will move downwards, blocking the guide tube 10, affecting normal operation. (Refer to...) Figure 1-9 In another preferred embodiment of the present invention, based on embodiment 1, the connecting mechanism includes a connecting frame 18, which is fixedly connected to the elliptical block 8. An elliptical ring 16 is sleeved on the outer periphery of the elliptical block 8, and an elliptical gap 21 is formed between the elliptical ring 16 and the elliptical block 8. A moving block 22 for changing the position of the connecting rod 9 is slidably disposed in the elliptical gap 21. The moving block 22 is fixedly connected to the connecting rod 9. When the elliptical block 8 rotates, it drives the connecting frame 18 to rotate together, thereby driving the elliptical ring 16 to rotate, so that the moving block 22 slides in the elliptical gap 21, driving the connecting rod 9 to move and changing the position of the connecting rod 9.

[0035] The movable block 22 is provided with a positioning rod 23, which is fixedly connected to the annular tube 5. The positioning rod 23 is used to limit the movement of the movable block 22, so that the movable block 22 can only move in the longitudinal direction.

[0036] A rotating block 20 is fixedly connected to the other end of the rotating shaft 6. A fixing part 24 is fixedly connected to the outer wall of the tank body 3. A sliding groove 17 is provided on the fixing part 24. The sliding groove 17 has an annular structure. A connecting block 26 is fixedly connected to the rotating block 20. The connecting block 26 is slidably disposed in the sliding groove 17. Four slots 28 are provided on the inner wall of the sliding groove 17. The four slots 28 correspond to the four vertices of the elliptical gap 21. A locking block 25 is locked in one of the slots 28. The locking block 25 is connected to the rotating block 20 through a triggering mechanism. When the elliptical block 8 rotates, it will drive the connecting block 26 to slide in the sliding groove 17. By aligning the slots 28 with the four vertices of the elliptical gap 21, the locking block 25 is positioned in the slot 28 when the rotating block 20 is rotated to the vertices, thereby limiting the position of the rotating block 20 and fixing the position of the elliptical block 8. This ensures that the water pump 11 will not affect the sealing plug 12 when it is working, thus ensuring the normal operation of the device.

[0037] Example 3: Reference Figure 7-9As another preferred embodiment of the present invention, based on embodiment 2, the triggering mechanism includes a spring 29, which is in a stretched state. One end of the spring 29 is fixedly connected to the rotating shaft 6, and the other end is fixedly connected to the locking block 25. Limiting grooves 15 are formed on the connecting block 26 and the rotating block 20. The locking block 25 is located in the limiting groove 15. One end of the locking block 25 is fixedly connected to a pressing part 27, which has an L-shaped structure. One end of the pressing part 27 is located on the outer side of the outer peripheral wall of the rotating block 20. By pushing the pressing part 27, the locking block 25 is allowed to enter the limiting groove 15, thereby releasing the fixing of the rotating block 20. This allows the rotating block 20 to be rotated to drive the elliptical block 8 to rotate. When the locking groove 28 is aligned with the locking block 25, the locking block 25 is automatically placed in the locking groove 28 under the action of the spring 29, thus limiting and fixing the rotating block 20.

[0038] The sealing plug 12 is made of food-grade silicone rubber, which meets food safety standards and has good temperature resistance, which helps to extend the service life of the sealing plug 12.

[0039] During the initial circulation phase, rotating block 20 causes the rotating shaft 6 to rotate, positioning the vertex of the minor axis of elliptical block 8 at its lowest point. Sealing plug 12 seals the vertical pipe 7 located above the guide pipe 10. When water pump 11 operates, water enters from the lower end of the vertical pipe 7 and sprays out from the through hole 4, thus mixing the liquid in the tank 3 through the upper and lower layers. In the middle and later stages of fermentation, pushing the pusher 27 causes the locking block 25 to enter the limiting groove 15, releasing the fixing of rotating block 20. Rotating rotating block 20 then causes elliptical block 8 to rotate. When the slot 28 and the block 25 are aligned, the block 25 is automatically placed in the slot 28 under the action of the spring 29. The block 25 limits the connection block 26 and prevents the connection block 26 from rotating. The connection block 26 is fixedly connected to the rotating block 20, thereby fixing the rotating block 20 and fixing the position of the elliptical block 8, so that the vertex of the major axis of the elliptical block 8 is at the lowest position, so that the sealing plug 12 descends and seals the vertical pipe 7 located at the lower part of the guide pipe 10, so that the upper end of the vertical pipe 7 is open, and the salt water in the upper part is circulated and sprayed out from the through hole 4 for circulation.

[0040] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
