Description

Technical Field

[0001] The utility model relates to the technical field of pickle production, in particular to a fermentation device for pickle production. Background Technique

[0002] At present, pickles refer to vegetables that have been fermented for long-term storage. They mainly rely on the fermentation of lactic acid bacteria to produce a large amount of lactic acid to inhibit spoilage microorganisms. After fermentation, pickles have a long storage time and rich flavors.

[0003] Among them, traditional pickle fermentation: Wash the ingredients, let them dry on one side; Cut the dried ingredients into pieces; Remove the stalks from the peppers; Put all the ingredients into the pickle jar and add salt; Boil water in a pot, add Chinese prickly ash and star anise leaves, bring to a boil and let it cool on one side; Remove the Chinese prickly ash, etc. from the cooled water and pour it into the pickle jar; Put it in the pickle jar; Cover the lid, seal it with clear water, and ferment in a cool place for ten days.

[0004] Traditionally, it is sealed by adding clear water inside the lid. Such an operation is not easy to control whether the clear water is evaporated and reduced, so the airtightness of the fermentation jar cannot be guaranteed. Therefore, new technical solutions need to be designed to solve this problem, which can not only well control the airtightness of the fermentation jar, but also discharge the gas generated inside the fermentation jar. Content of the Utility Model

[0005] The purpose of the utility model is to provide a fermentation device for pickle production, which solves the problems put forward in the background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A fermentation device for pickle production, including a fermentation jar, an expansion port is fixedly installed at the top of the fermentation jar, a sealing cover is installed on the expansion port by internal thread, and a sealing and pressure relief mechanism is installed on the sealing cover;

[0007] The sealing and pressure relief mechanism includes a screw rod threadedly installed in the middle of the sealing cover, a sealing plate rotatably installed at the bottom of the screw rod, an installation groove opened on the outer side of the sealing plate, an airbag fixedly installed on the inner wall of the installation groove, a rubber ring fixedly installed on the outer wall of the installation groove, a ventilation port communicated and installed on one side of the bottom of the sealing plate, a ventilation pipe communicated and installed at the top of the ventilation port, and a one-way valve fixedly installed at the other end of the ventilation pipe.

[0008] As an optional solution of the technical solution of the present application, the airbag is located between the rubber ring and the installation groove, and the sealing plate is movably connected to the inner wall of the fermentation jar.

[0009] As an optional solution of the technical solution of the present application, the one-way valve is installed on the top of the sealing cover, and a filter cover is inserted at the bottom of the ventilation port, which can filter the foam inside the fermentation jar.

[0010] As an alternative embodiment of the technical solution of the present application, brackets are fixedly installed on both sides of the bottom of the sealing plate, and a filter plate is fixedly installed at the bottom of the two brackets, which can squeeze the pickles.

[0011] As an alternative embodiment of the technical solution of the present application, a connecting block is fixedly installed in the middle of the outer wall of the cover. An external thread is provided on the outer wall of the connecting block, and the connecting block is threadedly connected to the inner wall of the expansion port, so that the cover can be screwed into the expansion port.

[0012] As an alternative embodiment of the technical solution of the present application, an air charging pipe is connected and installed on one side of the airbag, and a valve is fixedly installed at one end of the air charging pipe, which can inflate the airbag.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. In the technical solution of the present application, by rotating the screw in the middle of the sealing and pressure relief mechanism, the bottom sealing plate is continuously squeezed, so that the sealing plate fits against the inner wall of the fermentation tank and slowly moves down. In cooperation with the external air pump, the inside of the air charging pipe is continuously inflated, so that the airbag inside the installation groove continuously expands and squeezes the rubber ring outside the sealing plate, ensuring that the rubber ring outside the sealing plate fits tightly against the inner wall of the fermentation tank. This not only effectively ensures the airtightness of the pickles inside the fermentation tank, but also through the air permeable pipe installed on the sealing plate, the gas generated during the fermentation of the pickles can be discharged, avoiding the continuous concentration of gas inside the fermentation tank and making it difficult to open the fermentation tank.

Specific implementation mode

[0020] Please refer to Figure 1-2 , the utility model provides a technical solution: a fermentation device for pickled vegetables production, including a fermentation tank 1, an expansion port 11 is fixedly installed at the top of the fermentation tank 1, a sealing cover 12 is installed with internal thread in the expansion port 11, and a sealing and pressure relief mechanism is installed on the sealing cover 12;

[0021] The sealing and pressure relief mechanism includes a screw rod 2 installed with thread in the middle of the sealing cover 12, a sealing plate 21 rotatably installed at the bottom of the screw rod 2, an installation groove 22 opened on the outer side of the sealing plate 21, an airbag 23 fixedly installed on the inner wall of the installation groove 22, a rubber ring 24 fixedly installed on the outer wall of the installation groove 22, an air vent 25 communicated and installed on one side of the bottom of the sealing plate 21, an air vent pipe 26 communicated and installed at the top of the air vent 25, and a one-way valve 27 fixedly installed at the other end of the air vent pipe 26. The airbag 23 is located between the rubber ring 24 and the installation groove 22, and the sealing plate 21 is movably connected with the inner wall of the fermentation tank 1.

[0022] In this technical solution, by rotating the screw rod 2 in the middle of the sealing and pressure relief mechanism, continuously squeezing the sealing plate 21 at the bottom, making the sealing plate 21 fit against the inner wall of the fermentation tank 1 and slowly move down, and cooperating with an external air pump to continuously inflate the inside of the air charging pipe 33, the airbag 23 inside the installation groove 22 continuously expands and squeezes the rubber ring 24 outside the sealing plate 21, ensuring that the rubber ring 24 outside the sealing plate 21 closely fits against the inner wall of the fermentation tank 1. This not only effectively guarantees the sealing of the pickled vegetables inside the fermentation tank 1, but also through the air vent pipe 26 installed on the sealing plate 21, the gas generated during the pickled vegetables fermentation process can be discharged, avoiding the gas continuously concentrating inside the fermentation tank 1 and making it difficult to open the fermentation tank 1.

[0023] In some technical solutions, supports 3 are fixedly installed on both sides of the bottom of the sealing plate 21, and a filter plate 31 is fixedly installed at the bottom of the two groups of supports 3, which can squeeze the pickled vegetables.

[0024] In this technical solution, when the operator screws the screw rod 2 to squeeze the sealing plate 21, the filter plate 31 installed at the bottom of the sealing plate 21 will preferentially press the pickled vegetables inside the fermentation tank 1, effectively ensuring that the pickled vegetables inside the fermentation tank 1 are squeezed into the processed brine, and making the pickled vegetables fully mixed and fermented with the processed brine.

[0025] In some technical solutions, an air charging pipe 33 is communicated and installed on one side of the airbag 23, and a valve is fixedly installed at one end of the air charging pipe 33, which can inflate the airbag 23.

[0026] In this technical solution, after the external air pump is connected and installed to the air charging pipe 33, the airbag 23 inside can be continuously inflated, so that the airbag 23 inside the installation groove 22 continuously expands and presses the rubber ring 24 outside the sealing plate 21, ensuring that the rubber ring 24 outside the sealing plate 21 fits tightly against the inner wall of the fermentation tank 1.

[0027] In some technical solutions, a connecting block 32 is fixedly installed in the middle of the outer wall of the cover 12. The outer wall of the connecting block 32 is provided with an external thread, and the connecting block 32 is threadedly connected to the inner wall of the expansion port 11, and the cover 12 can be screwed into the expansion port 11.

[0028] In this technical solution, after the cover 12 is installed inside the expansion port 11, by matching the external thread on the outer wall of the connecting block 32 with the internal thread on the inner wall of the expansion port 11, the cover 12 can be installed inside the expansion port 11.

[0029] In some technical solutions, a one-way valve 27 is installed on the top of the cover 12, and a filter cover is inserted at the bottom of the air vent 25, which can filter the foam inside the fermentation tank 1.

[0030] In this technical solution, after the pickles inside the fermentation tank 1 are continuously fermented, a large amount of gas will be generated inside the fermentation tank 1. With the one-way valve 27 installed at the top of the air vent pipe 26, not only can the gas inside the fermentation tank 1 be discharged, but also the outside gas can be prevented from being introduced into the fermentation tank 1.

[0031] When a fermentation device for pickles production is in use, it should be noted that the present utility model is a fermentation device for pickles production, and each component is a general standard component or a component known to those skilled in the art. Its structure and principle can be known by those skilled in the art through technical manuals or by conventional experimental methods.

[0032] During use, first pour the pickles and the processed brine into the interior of the fermentation tank 1, then screw the cover 12 onto the expansion opening 11 at the top of the fermentation tank 1. At the same time, rotate the screw 2 in the middle of the sealing and pressure relief mechanism, continuously squeeze the sealing plate 21 at the bottom, so that the sealing plate 21 fits against the inner wall of the fermentation tank 1 and slowly moves down. Cooperate with an external air pump to continuously inflate the inside of the air charging pipe 33, so that the airbag 23 inside the installation groove 22 continuously expands and squeezes the rubber ring 24 outside the sealing plate 21, ensuring that the rubber ring 24 outside the sealing plate 21 closely fits against the inner wall of the fermentation tank 1. This not only effectively ensures the tightness of the pickles inside the fermentation tank 1, but also through the air permeable pipe 26 installed on the sealing plate 21, the gas generated during the fermentation of the pickles can be discharged, avoiding the continuous concentration of gas inside the fermentation tank 1 and making it difficult to open the fermentation tank 1. At the same time, both sides of the bottom of the sealing plate 21 are fixedly installed with brackets 3, and the bottom of the two groups of brackets 3 is fixedly installed with a filter plate 31. When the operator rotates the screw 2 to squeeze the sealing plate 21, the filter plate 31 installed at the bottom of the sealing plate 21 will preferentially add oil to the pickles inside the fermentation tank 1, effectively ensuring that the pickles inside the fermentation tank 1 are squeezed into the processed brine, so that the pickles and the processed brine are fully mixed and fermented.
