Description

Technical Field

[0001] The invention relates to the technical field of beer sterilization, in particular to a sterilization device for beer production. Background Art

[0002] In the beer production process, the water bath sterilization (also known as pasteurization) of the filled beer is to ensure the killing of harmful microorganisms (such as bacteria and yeast) that may be present in the beer, so as to avoid the possibility of beer spoilage or adverse effects on human health. At the same time, the sterilization process also helps to ensure the consistency of the beer and extend its shelf life, so that the beer can maintain stable quality during distribution and consumption. Therefore, a double-layer water bath sterilizer is used. When the equipment is used, the filled and capped beer is neatly placed in the placement frame, pushed into the sterilizer and the safety door is closed. Then the equipment is started to pump the hot water in the upper water storage kettle into the sterilizer to sterilize the beer. Finally, cooling water is used to cool the beer, and finally unloaded to complete the sterilization.

[0003] The patent with the current announcement number CN219930018U discloses a double-layer water bath type beer-specific sterilizing kettle, which improves the recycling effect of water resources, reduces water consumption, improves the convenience of different methods of beer sterilization in the sterilizing kettle, reduces the complexity of the separate setting of the steam box, reduces the equipment cost, and improves the functionality of the sterilizing kettle; specifically, it includes a base, a steam discharge device, a first tank body, a support seat, a second tank body, a heating device, a first valve, a first water pipe, a first water pump and a second valve. The first tank body is installed at the top of the base, a take-in and put-out port is provided at the left end of the first tank body, and a closed door is provided at the take-in and put-out port. The bottom end of the support seat is connected to the top of the first tank body, the second tank body is installed at the top of the support seat, and a heating device is provided at the bottom of the inner wall of the second tank body. The first valve is connected to the upper part of the outer wall of the second tank body, and the top end of the first water pipe is connected to the lower part of the outer wall of the second tank body.

[0004] Although the above device solves the problem of recycling water resources, it still has the following shortcomings: At present, two rows of placement frames can be placed in the kettle. However, when there is less beer to be sterilized and there is only one placement frame, the volume in the kettle cannot be changed, so the kettle still needs to be filled with hot water. This causes a large amount of hot water to heat, which requires more time and energy. At the same time, soaking a placement frame with a large amount of hot water will also cause a waste of water resources and inconvenience. Summary of the invention

When the sterilization kettle body is cleaning impurities on its inner wall, the accordion cover can be unfolded to make the sealing plate, the accordion cover and the rotating plate form a cylinder located in the sterilization kettle body. The sterilization kettle body is filled with hot water. While the hot water covers the outside of the sealing plate, the accordion cover and the rotating plate, the hot water can also fully contact with the inner wall of the sterilization kettle body and react fully.

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] See also Figure 1-Figure 12A sterilization device for beer production includes a sterilization kettle body 1, a hot water tank 2 connected to the top of the sterilization kettle body 1, a safety door 3 connected to the outer wall of the sterilization kettle body 1, and two guide rails 13 connected to the sterilization kettle body 1. The top of the sterilization kettle body 1 is connected and installed with a hot water inlet 11. The end of the sterilization kettle body 1 away from the safety door 3 is slidably connected with a sealing plate 4. The back of the sealing plate 4 is fixedly connected with a U-shaped frame 16. The outer wall of the sterilization kettle body 1 is fixedly connected with an electric push rod 6. The electric push rod 6 The output end is penetrated by the sterilizing kettle body 1 and fixedly connected with the outer wall of the U-shaped frame 16. The lower end of the sealing plate 4 is provided with two symmetrically arranged M-shaped grooves 26, and the M-shaped grooves 26 are slidably connected with the guide rail 13. The outer wall of the sealing plate 4 is provided with a first annular gasket groove 27. The first gasket groove 27 and the M-shaped groove 26 are sleeved with a first sealing ring 5 and an M-shaped sealing gasket 25. The first sealing ring 5 and the M-shaped sealing gasket 25 are fixedly connected. The outer wall of the sealing plate 4 is connected with a rotating mechanism, and the bottom of the sealing plate 4 is connected with a steam pipe assembly.

[0021] In the sterilization device for beer production of the present invention, when there is only one placement frame in the sterilization kettle body 1, the electric push rod 6 can be turned on at this time, and the electric push rod 6 will drive the sealing plate 4 to move in the sterilization kettle body 1. While the sealing plate 4 moves, the first sealing ring 5 and the M-shaped sealing gasket 25 will slide with the inner wall of the sterilization kettle body 1 and the outer side of the guide rail 13. When the sealing plate 4 moves to the side close to the placement frame, the hot water inlet 11 can pump the hot water in the hot water tank 2 into the sterilization kettle body 1. Since the sealing plate 4 is close to the side of the placement frame, the volume of the sterilization kettle body 1 can be changed, thereby reducing the amount of hot water and reducing the waste of water resources. The reduction in the amount of water will reduce the heating time, thereby reducing energy consumption, and at the same time, it can also reduce the waiting time, thereby improving the sterilization efficiency.

[0022] The electric push rod 6 here should be sealed and connected to the sterilizing kettle body 1. The electric push rod 6 is an existing mature technology and will not be described in detail here.

[0023] The outer wall of the sterilizing kettle body 1 should be provided with water inlet and outlet pipes and sewage pipes of the cooling system to ensure the normal operation of the sterilizing kettle body 1 during cooling.

[0024] The sealing plate 4 is pushed by the electric push rod 6 to move the sealing plate 4 in the sterilizing kettle body 1. When the sterilizing kettle body 1 only sterilizes beer for one group of placement frames, the movement of the sealing plate 4 can change the volume of the sterilizing kettle body 1, thereby reducing the amount of hot water, thereby reducing the waste of water resources. The smaller amount of water can reduce the heating time of water, reduce energy consumption, and reduce the waiting time for hot water heating, thereby improving the sterilization efficiency; the M-shaped groove 26 is used to make the movement of the sealing plate 4 not restricted by the guide rail 13, and the first sealing ring 5 and the first M-shaped sealing gasket 25 can block the left and right sides of the sealing plate 4 to prevent water penetration.

[0025] As a preferred technical solution of the present invention, the steam pipe assembly includes a first steam pipe 14, which is fixedly connected to the bottom of the sterilization kettle body 1 near the safety door 3, and a second steam pipe 15 is slidably connected inside the first steam pipe 14. The outer walls of the second steam pipe 15 and the first steam pipe 14 are both provided with steam holes 19. The lower end of the first steam pipe 14 is connected to a steam inlet pipe 12, and the end of the second steam pipe 15 is fixedly connected to the outer wall of the sealing plate 4.

[0026] Specifically, in order to prevent the sealing plate 4 from affecting the heating of hot water in the sterilizing kettle body 1 when it moves, when the sealing plate 4 moves, it will drive the second steam pipe 15 to move in the first steam pipe 14. Since the moving distance of the sealing plate 4 is only the distance of a placement frame, and the length of the first steam pipe 14 is slightly greater than the length of a placement frame, the first steam pipe 14 can overlap in the second steam pipe 15, and when overlapping, the steam hole 19 will also overlap, ensuring that the steam can smoothly pass through the first steam pipe 14 and the second steam pipe 15 in the steam inlet pipe 12. The end of the steam inlet pipe 12 here should be connected to a steam generator or a steam boiler, which is a prior art and will not be described in detail. When two placement frames are placed on the sterilization kettle body 1, the electric push rod 6 will drive the sealing plate 4 to retreat and restore its position. At this time, the second steam pipe 15 will be driven by the movement of the sealing plate 4 to move and unfold with the first steam pipe 14. At this time, the steam holes 19 on the two steam pipes are fully unfolded, so that the steam can be exposed through the steam holes 19 smoothly to continuously heat the hot water.

[0027] As a preferred technical solution of the present invention, a second gasket groove 31 is formed on the inner wall of the open end of the first steam pipe 14 , a second sealing ring 32 is embedded in the second gasket groove 31 , and the inner wall of the second sealing ring 32 is sealed against the outer wall of the second steam pipe 15 .

[0028] Specifically, when the second steam pipe 15 moves in the first steam pipe 14, the second sealing ring 32 will always fit with the outer wall of the second steam pipe 15. This arrangement can prevent steam and steam water from leaking between the second steam pipe 15 and the first steam pipe 14, resulting in a reduction in the vertical upward effect of the steam hole 19.

[0029] As a preferred technical solution of the present invention, the rotating mechanism includes a rotating plate 7, the outer wall of the rotating plate 7 is fixedly connected to a central fixed block 18, the outer wall of the central fixed block 18 is fixedly connected to a plurality of rib plates 8 fixedly connected to the rotating plate 7, the outer wall of the sealing plate 4 is fixedly connected to a rotating motor 10, the output end of the rotating motor 10 passes through one end of the sealing plate 4 and is fixedly connected to a rotating shaft 23, the rotating shaft 23 is connected to the inner wall of the rotating plate 7, and the annular frame 24 is fixedly connected to the outer wall of the sealing plate 4.

[0030] Specifically, when the sterilization kettle body 1 is performing sterilization work, the rotating motor 10 can be started, and the output shaft of the rotating motor 10 rotates to drive the rotating shaft 23 to rotate, and then drives the rotating plate 7 to rotate, and the rotating plate 7 drives a number of rib plates 8 to rotate. Since the rib plates 8 are in a convex state, the hot water located in the sterilization kettle body 1 can be rotated well, thereby accelerating the mixing of the hot water, thereby effectively improving the heat exchange effect between beer and hot water, and improving the heating effect and sterilization efficiency.

[0031] The rotating motor 10 here is an existing mature technology and will not be described in detail here.

[0032] As a preferred technical solution of the present invention, the outer wall of the sealing plate 4 is fixedly connected with an accordion cover 9, the other end of the accordion cover 9 is rotatably connected to the sealing plate 4, the inner wall of the rotating plate 7 is fixedly connected with an axis connecting block 20, a rectangular groove 21 is opened in the axis connecting block 20, and the end of the rotating shaft 23 is fixedly connected with a rectangular block 22 corresponding to the rectangular groove 21.

[0033] Specifically, after the sterilizing kettle body 1 has been working for a period of time, some impurities will dry on its inner wall and need to be cleaned. The conventional cleaning method is to add hot water and chemical cleaning agents to allow the cleaning agents to fully contact and react with the impurities through soaking. However, the volume of the sterilizing kettle body 1 is large. At this time, the sealing plate 4 is first retreated and restored to the initial position, and then the worker can pull the rotating plate 7 to drive the accordion cover 9 to unfold, and limit the rotating plate 7 and the sterilizing kettle body 1 near the safety door 3. At this time, hot water is injected for soaking. Since the sealing plate 4, the accordion cover 9 and the rotating plate 7 form a cylinder located in the sterilizing kettle body 1, the sterilizing kettle body 1 is filled. While the hot water covers the outside of the sealing plate 4, the accordion cover 9 and the rotating plate 7, the hot water can also fully contact and react with the inner wall of the sterilizing kettle body 1. This arrangement reduces the large amount of water resources originally required to fill the sterilizing kettle body 1, avoids the waste of water resources, and reduces energy consumption.

[0034] In order to ensure that the rotating plate 7 can rotate smoothly, when the rotating shaft 23 rotates, the rectangular block 22 at its end is inserted into the rectangular groove 21 in the shaft connecting block 20, so as to ensure that the rotating plate 7 will rotate along with the rotating motor 10 when it rotates.

[0035] When the accordion cover 9 is pulled open, the rectangular block 22 will be separated from the rectangular groove 21. When the accordion cover 9 is restored, the rectangular block 22 will be plugged into the rectangular groove 21. This arrangement can ensure the smooth rotation of the rotating plate 7.

[0036] As a preferred technical solution of the present invention, an annular groove 28 is provided on one side of the rotating plate 7 close to the accordion cover 9 , and an annular sliding bar 29 fixedly connected to the end of the accordion cover 9 is rotatably connected in the annular groove 28 .

[0037] Specifically, in order to ensure that the accordion cover 9 is not affected when the rotating shaft 23 rotates, when the rotating plate 7 rotates, the annular slide bar 29 at the bottom of the accordion cover 9 will rotate in the annular groove 28 to prevent the accordion cover 9 from rotating with it.

[0038] As a preferred technical solution of the present invention, the outer wall of the rotating plate 7 is connected to a plurality of limit members, the limit members include a limit plate 17, the bottom surface of the limit plate 17 is abutted against the top surface of the step groove 38, a limit rotation groove 33 is provided on the top of the limit plate 17, a plurality of first limit bars 34 are fixedly connected to the inner wall of the limit rotation groove 33, a vertical shaft 35 fixedly connected to the rotating plate 7 is rotatably connected in the limit rotation groove 33, a plurality of second limit bars 36 are fixedly connected to the outer wall of the vertical shaft 35, the first limit bars 34 and the second limit bars 36 are staggered, and a rotating plate 30 is fixedly connected to the outer side of the top end of the vertical shaft 35.

[0039] Specifically, when the rotating plate 7 needs to be fixed, the multiple limit plates 17 can be rotated so that they are abutted against the step groove 38 after being rotated 180 degrees. Since the length of the accordion cover 9 after being unfolded plus the thickness of the rotating plate 7 can be slightly smaller than the distance between the sealing plate 4 and the step groove 38 after being reset, when the accordion cover 9 is unfolded, the limit plates 17 abut against the step groove 38, which can just straighten the accordion cover 9. By simply abutting against the step groove 38, the accordion cover 9 can be fixed after being pulled open, which is simple and convenient.

[0040] When the limiting plate 17 rotates, the first limiting strip 34 and the second limiting strip 36 rotate in an offset manner. This arrangement allows the limiting plate 17 to be limited outside the vertical axis 35 .

[0041] As a preferred technical solution of the present invention, an arc strip 37 is fixedly connected to the outer end of the rib plate 8 .

[0042] Specifically, the arrangement of the arc strips 37 can increase the mixing effect of the rib plates 8, thereby increasing the tumbling effect of the water.

[0043] As a preferred technical solution of the present invention, an annular frame 24 is fixedly sleeved on the outer wall of the rotating motor 10 .

[0044] Specifically, the provision of the annular frame 24 can facilitate the installation of the rotating motor 10 .

[0045] As a preferred technical solution of the present invention, the cross-sections of the annular slide bar 29 and the annular groove 28 are T-shaped or wedge-shaped. By setting the cross-sections of the annular slide bar 29 and the annular groove 28 to be T-shaped or wedge-shaped, the annular slide bar 29 and the annular groove 28 can be smoothly rotated and not separated from each other, and the processing manufacturer can also have multiple choices during production.

[0046] All the above-mentioned component structures should be made of high-temperature resistant materials, or the outer walls of the structures should be coated with high-temperature resistant materials to ensure the stable use of the component structures in the sterilization kettle body 1.

[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
