Abstract
Description
Technical Field
[0001] This utility model relates to the field of sauerkraut fermentation technology, specifically to a sauerkraut fermentation device that can quickly produce sauerkraut. Background Technology
[0002] Traditional sauerkraut fermentation has long relied on simple containers such as earthenware jars and wooden barrels, which have many limitations. When harvesting the sauerkraut, it is necessary to manually pour or dig it out, which is not only labor-intensive but also easily causes damage to the sauerkraut and is inefficient.
[0003] During the fermentation of sauerkraut, excessive carbon dioxide accumulation in the tank can inhibit the activity of beneficial bacteria such as lactic acid bacteria, disrupt the balance of fermentation bacteria, and lead to decreased fermentation efficiency, prolonged fermentation cycle, and even changes in the flavor of sauerkraut, resulting in excessive sourness or blandness. In addition, the gas pressure inside the tank increases continuously with the accumulation of carbon dioxide, which may exceed the pressure limit of the device structure. Therefore, we have proposed a sauerkraut fermentation device that can quickly produce sauerkraut. Utility Model Content
[0004] The purpose of this invention is to provide a sauerkraut fermentation device that can quickly produce sauerkraut, in order to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a sauerkraut fermentation device for rapid pickling, comprising a fermentation tank, a feed pipe connected to the top of the fermentation tank, and further comprising:
[0006] A pressure detection assembly includes a connector connected to the inner wall of a fermenter, an elastic diaphragm rotatably connected to the bottom of the connector, a top rod connected to the top of the elastic diaphragm, and the top rod slidably connected to the fermenter.
[0007] The pressure relief assembly includes a support rod connected to the top of the fermenter, a rotating shaft rotatably connected to the top of the support rod, a drive plate connected to the top of the rotating shaft, a connecting rod connected to the bottom of the drive plate, a baffle connected to the bottom of the connecting rod, and a pressure relief port on the fermenter.
[0008] Furthermore, a limiting groove is provided on the side of the fermenter near the baffle, and a limiting block is slidably connected to the limiting groove, with the baffle connected to the limiting block.
[0009] The above technical solution is adopted: by setting limit grooves and limit blocks, the trajectory of the baffle during the movement process is limited.
[0010] Furthermore, the fermenter is equipped with a compaction assembly, which includes a cylinder connected inside the fermenter, and a pressure plate is connected to the output end of the cylinder.
[0011] By adopting the above technical solution, the sauerkraut raw material can be tightly compacted by setting up a compaction component, which can promote the uniform penetration of organic acids and other substances produced by lactic acid bacteria metabolism into each part of the raw material.
[0012] Furthermore, the fermentation tank is provided with a food-retrieving component at the bottom, the food-retrieving component includes a discharge port opened at the bottom of the fermentation tank, the fermentation tank is provided with a threaded section, and an end cap is threadedly connected to the bottom of the fermentation tank.
[0013] Using the above technical solution: by setting up a food retrieval component, the end cap can be unscrewed from the bottom of the fermentation tank to retrieve the food.
[0014] Furthermore, a handle is connected to the bottom of the end cap, and a vent is provided on the end cap.
[0015] The above technical solution allows for material discharge by setting up a sluice gate and slightly twisting the end cap to align the sluice gate with the discharge port.
[0016] Furthermore, the fermenter is provided with a support assembly, which includes an extension plate connected to the fermenter, and a support leg connected to the bottom of the extension plate.
[0017] The above technical solution involves setting up support components to support and fix the fermenter.
[0018] Furthermore, a spring is connected to the top of the fermenter, and the top of the spring is connected to the bottom of the drive plate.
[0019] The above technical solution is adopted as follows: by setting a spring, when the internal pressure decreases and the elastic diaphragm returns to its original position, the thrust on the drive plate is canceled. The drive plate then automatically drives the baffle to reset and block the pressure relief port through the elastic force of the spring contraction.
[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0021] In this invention, by setting up a pressure detection component, the internal pressure can be detected in real time, and the pressure can be released in time through a pressure relief component, ensuring production efficiency. This solves the problem of excessive carbon dioxide accumulation in the tank during the fermentation of sauerkraut. Excessive carbon dioxide concentration will inhibit the activity of beneficial bacteria such as lactic acid bacteria, disrupt the balance of fermentation bacteria, and lead to decreased fermentation efficiency, prolonged cycle, and even cause changes in the flavor of sauerkraut, resulting in excessive sourness or blandness. In addition, the gas pressure in the tank will continue to rise as carbon dioxide accumulates, which may exceed the pressure bearing limit of the device structure. Attached Figure Description

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0035] like Figures 1-4 As shown, this utility model provides a technical solution: a sauerkraut fermentation device that can quickly produce sauerkraut, including a fermentation tank 1, a feed pipe 2 connected to the top of the fermentation tank 1, and further including:
[0036] Pressure detection assembly 3 includes a connector 32 connected to the inner wall of fermenter 1, an elastic diaphragm 31 rotatably connected to the bottom of connector 32, a top rod 33 connected to the top of elastic diaphragm 31, and the top rod 33 slidably connected to fermenter 1.
[0037] The pressure relief assembly 4 includes a support rod 42 connected to the top of the fermenter 1, a rotating shaft 43 rotatably connected to the top of the support rod 42, a drive plate 41 connected to the top of the rotating shaft 43, a connecting rod 44 connected to the bottom of the drive plate 41, a baffle 45 connected to the bottom of the connecting rod 44, a pressure relief port 46 opened on the fermenter 1, and a spring 9 connected to the top of the fermenter 1, with the top of the spring 9 connected to the bottom of the drive plate 41.
[0038] Specifically, when the carbon dioxide concentration inside the fermenter 1 is too high, it will generate greater pressure. At this time, the elastic diaphragm 31 will deform, thereby driving the top rod 33 to rise. During the rising process, the top rod 33 will push the drive plate 41 to rotate through the rotating shaft 43. During the rotation, the drive plate 41 will simultaneously squeeze the spring 9 and drive the connecting rod 44 at the bottom to rise. The connecting rod 44 will drive the baffle 45 to rise, thereby releasing the pressure relief port 46 to relieve pressure.
[0039] Furthermore, such as Figure 1 As shown: A support assembly 7 is provided on the fermentation tank 1. The support assembly 7 includes an extension plate 71 connected to the fermentation tank 1. A support leg 72 is connected to the bottom of the extension plate 71 for supporting and fixing the fermentation tank 1.
[0040] The above solution also requires that the trajectory of the baffle 45 during its movement be limited to ensure that it always adheres to the surface of the fermenter 1. Figure 3 As shown: A limiting groove 8 is provided on the side of the fermenter 1 near the baffle 45. A limiting block is slidably connected to the limiting groove 8. The baffle 45 is connected to the limiting block. During the movement of the baffle 45, the limiting block will be driven to slide in the limiting groove 8.
[0041] The above methods also include the requirement to compact the sauerkraut during fermentation to ensure that the organic acids and other substances produced by lactic acid bacteria are evenly distributed into each part of the raw material. Figure 4 As shown: The fermentation tank 1 is equipped with a compaction component 6. The compaction component 6 includes a cylinder 61 connected inside the fermentation tank 1. The output end of the cylinder 61 is connected to a pressure plate 62. When the cylinder 61 is turned on, it drives the pressure plate 62 to compact the sauerkraut.
[0042] Furthermore, such as Figure 3 As shown: The fermentation tank 1 is equipped with a food dispensing component 5 at the bottom. The food dispensing component 5 includes a discharge port 51 at the bottom of the fermentation tank 1. The fermentation tank 1 is provided with a threaded section 55. An end cap 52 is threadedly connected to the bottom of the fermentation tank 1. A handle 54 is connected to the bottom of the end cap 52. A sluice gate 53 is provided on the end cap 52. By turning the handle 54, the end cap 52 is rotated slightly, and the sluice gate 53 is aligned with the discharge port 51 to discharge the food.
[0043] The working principle provided by this utility model is as follows: Figures 1-4As shown: First, the sauerkraut is poured into the fermentation tank 1 through the feed pipe 2. Then, the cylinder 61 is turned on to drive the pressure plate 62 to compact the sauerkraut. When the carbon dioxide concentration inside the fermentation tank 1 is too high, a large pressure will be generated. At this time, the elastic diaphragm 31 will deform, thereby driving the top rod 33 to rise. During the rising process, the top rod 33 will push the drive plate 41 to rotate through the rotating shaft 43. During the rotation of the drive plate 41, it will simultaneously squeeze the spring 9 and drive the bottom connecting rod 44 to rise. The connecting rod 44 will drive the baffle 45 to rise. During the movement of the baffle 45, it will simultaneously drive the limiting block to slide in the limiting groove 8, thereby releasing the pressure through the pressure relief port 46. Finally, the handle 54 is turned to drive the end cover 52 to rotate slightly, aligning the outlet 53 with the discharge port 51 to discharge the material.
[0044] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. The implementation schemes in the above embodiments can also be further combined or replaced. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
