Description

A pickle device that does not produce nitrite Technical Field

[0001] The invention relates to the technical field of pickled vegetable holding containers, in particular to a pickled vegetable device that does not generate nitrite. Background Art

[0002] Currently, kimchi pickling is commonly done in traditional water-sealed kimchi jars, which are sealed to provide favorable conditions for anaerobic fermentation of probiotics. However, even after sealing, these jars retain a certain amount of air, which fosters the growth of harmful bacteria, leading to unpleasant odors, a "garbled" texture, and deterioration during kimchi fermentation. Furthermore, the reductase produced by these bacteria reduces nitrates to nitrites, limiting kimchi consumption. This necessitates increased salt usage to suppress the growth of these bacteria. However, high salt concentrations also inhibit the growth of probiotics, slowing the increase in kimchi acidity and thus the acidic degradation of nitrites. Consequently, it takes a long time for the dynamic balance between nitrite production and degradation to reach the national standard limit. In reality, for families, workplace catering agencies, and restaurants that prepare their own kimchi, they lack the ability or motivation to thoroughly examine the quality of their kimchi, particularly its nitrite content. This uncertainty in the quality of homemade kimchi poses a significant risk to its safe consumption. Today, when people are paying more and more attention to food safety, it is imperative to find a kimchi fermentation device that does not produce nitrite. Summary of the Invention

[0003] The present invention aims to provide a kimchi-making device that does not produce nitrite. The device can maintain an oxygen-free environment within the jar after sealing, providing favorable conditions for the growth of anaerobic bacteria during the fermentation process of pickled vegetables. This strictly limits the growth of harmful bacteria, eliminates the production of nitrite, and also prevents the pickled vegetables from having an unpleasant odor, becoming "garbled," or becoming corrupted, thereby ensuring food safety.

[0004] The present invention adopts the following technical solutions:

[0005] A pickle making device that does not produce nitrite includes a receiving portion, which is a hollow and deformable structure; a top end of the receiving portion is provided with a taking-in and putting-out port connected to the interior thereof, a sealing cover is detachably provided at the taking-in and putting-out port, and a gas exhaust valve connected to the receiving portion is provided on the sealing cover.

[0006] Preferably, the entire accommodating portion is a deformable non-rigid structure.

[0007] Preferably, the accommodating portion includes a deformable buffer section and a shaping section connected to the buffer section.

[0008] Preferably, the buffer section is an expandable or compressible flexible structure.

[0009] Preferably, the buffer section is in a corrugated shape.

[0010] Preferably, the buffer section is arranged at the top, and the shaping section is arranged at the bottom.

[0011] Preferably, the access opening above the accommodating portion is protruding upward and is a fixed structure with a certain strength.

[0012] Preferably, the accommodating portion is a deformable bag-shaped structure.

[0013] Preferably, the accommodating portion is a deformable cylindrical structure.

[0014] Preferably, the exhaust valve is a one-way valve.

[0015] Compared to existing technologies, the present invention offers the following advantages: by designing the container into a deformable structure and providing an exhaust valve on the sealing lid, after placing the pickled vegetables inside and closing the lid, the container is squeezed to deform, expelling any remaining gas from the container, creating an oxygen-free fermentation environment. This simple "gas and oxygen-free" principle prevents the growth of harmful bacteria, ensuring that no nitrite is produced during the kimchi fermentation process, fundamentally and completely resolving this problem.

[0016] It also has the following advantages: 1. It can significantly reduce the amount of salt used and significantly increase the fermentation speed. This significantly reduces salt intake, which is significantly beneficial to health. 2. It effectively eliminates nitrites, not only ensuring food safety, but also allowing people to consume kimchi simply by judging the fermentation completion based on color, aroma, flavor, and taste. There is no need to consider the nitrite time curve, allowing flexible consumption time selection. 3. The kimchi no longer has an odor, "flowering," or corruption, significantly improving its quality. 4. It significantly reduces the difficulty of the kimchi-making process, ensuring that it will not fail unless there is a reverse operation. It also facilitates the exhaust operation each time the pickled vegetables are removed and the exhaust of fermentation gases during the fermentation process, ensuring smooth fermentation. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] FIG1 is a schematic structural diagram of Example 1 of the present application;

[0018] FIG2 is a schematic structural diagram of the second embodiment of the present application. Implementation Method

[0019] The present invention will be described clearly and completely below with reference to the accompanying drawings and embodiments:

[0020] As shown in Figures 1 to 2, the pickle device described in the present invention does not produce nitrite, includes a accommodating portion 1, which is a hollow and deformable structure. By squeezing the accommodating portion 1, it is deformed and the liquid inside is pushed up to the exhaust valve 2, so that the gas inside the accommodating portion 1 is discharged, providing an anaerobic environment for the fermentation of vegetables; at the same time, the deformable structure can also use its own deformation during the fermentation process to provide a certain buffer space for the pressure change in the accommodating portion 1 during the fermentation process; the top of the accommodating portion 1 is provided with a taking and releasing port 3 that is connected to the interior of the accommodating portion 1, and a sealing cover 4 is detachably provided at the taking and releasing port 3, and an exhaust valve 2 that is connected to the accommodating portion 1 is provided on the sealing cover 4. The exhaust valve 2 adopts a one-way valve to ensure that the gas can be discharged from the accommodating portion 1 to the outside, while the external gas cannot enter the accommodating portion 1, providing favorable conditions for fermentation.

[0021] In order to meet different usage conditions, this embodiment optimizes the specific structure of the accommodating portion 1 as follows: Example

[0022] As shown in Figure 1, the entire container 1 is a deformable, non-rigid structure. Specifically, it can be formed into a deformable, bag-like structure. Using a thick, soft plastic material, the bag-like structure facilitates extrusion and degassing, making it easy to store and place within a container. This facilitates production and processing, allowing it to be manufactured in a variety of sizes to meet varying consumption requirements, offering great flexibility and practicality. Alternatively, using a plastic material with good deformation properties, the container 1 can be configured as a deformable cylindrical or jar-like structure. Initially, the container 1 has a specific shape, providing support and ease of placement through compression and degassing. In this embodiment, when the container 1 is an entirely deformable, non-rigid structure, the shape is not limited to the two aforementioned configurations; it can also be configured into a variety of desired shapes based on practical needs. Furthermore, in this embodiment, the access opening 3 on the top of the container 1 is configured to project upward and possess a certain strength, facilitating the installation and connection of the sealing cover 4 and the removal and placement of pickled vegetables.

[0023] Example 2

[0024] As shown in FIG2 , the accommodating portion 1 in this embodiment includes a deformable buffer section 1-1 and a shaping section 1-2 connected to the buffer section 1-1; wherein the buffer section 1-1 is preferably arranged at the top and the shaping section 1-2 is arranged at the bottom, so that when in use, the shaping section 1-2 can provide stable support for the entire accommodating portion 1; the shaping section 1-2 can be made of a plastic material with a deformation degree less than that of the buffer section 1-1, or can be made of a material that has no deformation ability at all, and the specific adaptive selection can be made according to actual needs. In this embodiment, the buffer section 1-1 is a flexible structure that can be extended or compressed, so that the buffer section 1-1 can be deformed by compressing it to complete the discharge of the gas in the accommodating portion 1; specifically, the two ends of the buffer section 1-1 are processed into a pleated shape, so that the buffer section 1-1 can be compressed and stretched in an orderly manner to complete the change in the volume of the accommodating portion 1, satisfying the discharge of the gas inside the accommodating portion 1 while providing a buffer space for the pressure change in the accommodating portion 1. In addition, in this embodiment, the access opening 3 above the accommodating portion 1 is protruding upward and is a fixed structure with a certain strength to facilitate the installation and removal of the sealing cover 4 and the access opening 3, while providing convenience for the subsequent access to pickled vegetables.

[0025] During use, the present invention first places the processed raw vegetables into the container 1. The desired fermentation liquid (e.g., boiled water of appropriate salinity and a culture medium or kimchi broth) is then added, followed by the sealing cover 4. An external force is then applied to the container 1 to compress it. The liquid moves upward as the container 1 deforms, until it enters the pipe of the exhaust valve 2, completing the exhaust operation within the container 1. This deprives the container 1 of the oxygen required for growth of harmful bacteria, inhibiting their reproduction and the production of reductase, thereby effectively preventing the reduction of nitrates to nitrites. Simultaneously, the low salinity and low osmotic pressure relax the inhibitory effect on probiotics, accelerating fermentation and preventing the kimchi from becoming stale or spoiling. Furthermore, the present invention boasts a simple structure and is easy to operate. The method can be mastered without specialized training, making it suitable for a wide range of users.
