Description

Technical Field

[0001] This utility model relates to the field of food processing, and in particular to a device for desalting and removing nitrite from pickled vegetables. Background Technology

[0002] Pickling vegetables requires a large amount of salt (usually 10%-20%) to inhibit microbial growth. However, a long-term high-salt diet can lead to health problems such as high blood pressure, cardiovascular disease, and stomach cancer. In the initial stage of pickling (3-7 days), nitrate-reducing bacteria proliferate rapidly, causing a rapid increase in nitrite content. However, some pickled vegetables may have residual high levels of nitrite due to processing issues. Under the action of gastric acid, nitrite can react with amines to form nitrosamines (such as dimethylnitrosamine), which is a strong carcinogen. Excessive intake of nitrite (>0.3-0.5 grams) can lead to methemoglobinemia, causing symptoms such as dizziness, nausea, and cyanosis. In severe cases, it can be fatal. Therefore, a device for desalting and removing nitrite from pickled vegetables is proposed. Summary of the Invention

[0003] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0004] A device for desalting and removing nitrite from pickled vegetables includes a support platform, a fixed frame vertically fixed on the support platform, and a first pickled vegetable processing tank and a second pickled vegetable processing tank disposed on both sides of the outside of the fixed frame. The fixed frame is provided with a desalting treatment mechanism for desalting and adsorbing the pickled vegetables and a purification mechanism for removing nitrite from the pickled vegetables on one side inside the fixed frame. The desalting treatment mechanism is pipe-connected to the first pickled vegetable processing tank, and the purification mechanism is pipe-connected to the second pickled vegetable processing tank.

[0005] Preferably, the desalination treatment mechanism includes activated carbon filter rods, ceramic filter rods and fiber filter rods disposed inside the fixed frame, and the activated carbon filter rods, ceramic filter rods and fiber filter rods are connected by pipes, and the activated carbon filter rods are connected to a first transmission pipe, and the first transmission pipe is provided with a third transmission pipe connected to the first pickle processing tank.

[0006] Preferably, the sixth transmission pipe is equipped with a second booster pump that draws brine from inside the first pickle processing tank to the first transmission pipe, and the second booster pump is equipped with a second mounting base that fixes it to the support platform, and the fiber filter rod is equipped with a sixth transmission pipe that is pipe-connected to the first pickle processing tank.

[0007] Preferably, the activated carbon filter rod has a first connecting pipe on one side that is connected to the ceramic filter rod, the ceramic filter rod has a second connecting pipe on one side that is connected to the fiber filter rod, and the fiber filter rod has a third connecting pipe on one side that is connected to the sixth transmission pipe.

[0008] Preferably, the sixth transmission pipe is provided with a first booster pump that is connected to the first pickled vegetable processing tank, and the first booster pump is provided with a second transmission pipe that is connected to the first pickled vegetable processing tank. The second transmission pipe and the first booster pump are connected with a pipe head, and the first booster pump is provided with a first mounting base that fixes it to the support platform.

[0009] Preferably, the second booster pump is provided with a fifth transmission pipe connected to the first transmission pipe, and the other end of the fifth transmission pipe is connected to a third transmission pipe connected to the second booster pump. The second booster pump is also provided with a second mounting base for fixing it to the support platform.

[0010] Preferably, the purification mechanism includes an ion exchange resin filter rod, a first reverse osmosis membrane filter rod, and a second reverse osmosis membrane filter rod disposed on the other side inside the fixed frame. A fourth transmission pipe is connected between the ion exchange resin filter rod, the first reverse osmosis membrane filter rod, and the second reverse osmosis membrane filter rod. The fourth transmission pipe is connected to the ion exchange resin filter rod, the first reverse osmosis membrane filter rod, and the second reverse osmosis membrane filter rod, and the other end of the fourth transmission pipe is connected to the second pickle processing tank.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: After the pickled vegetables are soaked in the first pickled vegetable processing tank and left for a period of time, due to the salt concentration difference inside and outside the cells, water will enter the cells through the semipermeable membrane (cell membrane), while salt (ions) diffuse outward into the water, forming a dynamic equilibrium. At this time, the pickled vegetable brine formed inside the first pickled vegetable processing tank is extracted to the desalination treatment mechanism for multiple desalination treatments, and the desalinated water is then flowed back into the first pickled vegetable processing tank. This allows the pickled vegetables inside the first pickled vegetable processing tank to be soaked multiple times, and multiple soakings can accelerate the dissolution of salt in the pickled vegetables and reduce the sodium ions in the pickled vegetables. The concentration of the brine produced during the soaking of pickled vegetables is controlled. The brine undergoes multiple desalination processes in the desalination unit, allowing for repeated use and preventing waste. After desalination, the pickled vegetables are removed from the first processing tank and placed into the second processing tank. Simultaneously, a vitamin C mixture is added to the second processing tank. The vitamin C mixture reduces nitrite to non-toxic nitrogen or nitric oxide, while the nitrite itself is oxidized to dehydroascorbic acid. This dehydroascorbic acid precipitates at the bottom of the second processing tank, and the generated nitrogen or nitric oxide is discharged. The residual liquid inside the second processing tank is filtered and purified by a purification system.

[0017] 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.

[0018] Please see Figure 1-3In this embodiment of the invention, a device for desalting and removing nitrite from pickled vegetables includes a support platform 1, a frame 2 vertically fixed on the support platform 1, and a first pickled vegetable processing tank 10 and a second pickled vegetable processing tank 11 disposed on both sides of the outside of the frame 2. The frame 2 has a desalination mechanism for desalting and adsorbing the pickled vegetables and a purification mechanism for removing nitrite from the pickled vegetables on one side inside. The desalination mechanism is pipe-connected to the first pickled vegetable processing tank 10, and the purification mechanism is pipe-connected to the second pickled vegetable processing tank 11. When the pickled vegetables are soaked in the first pickled vegetable processing tank 10 and left for a period of time, due to the salt concentration difference between the inside and outside of the cells, water will enter the cells through the semi-permeable membrane (cell membrane), while salt (ions) diffuse outwards into the water, forming a dynamic equilibrium. At this time, the contents of the first pickled vegetable processing tank 10... The brine formed during pickling is extracted into a desalination unit for multiple desalination processes. The desalinated water is then returned to the first pickling processing tank 10, allowing the pickles inside to be soaked multiple times. Multiple soaking accelerates the dissolution of salt and reduces the sodium ion concentration in the pickles. The brine generated from soaking the pickles can be reused repeatedly after multiple desalination processes, preventing waste. The desalinated pickles are then removed from the first pickling processing tank 10 and placed into the second pickling processing tank 11. Simultaneously, a vitamin C mixture is added to the second pickling processing tank 11. The vitamin C mixture reduces nitrite to non-toxic nitrogen or nitric oxide, while the nitrite itself is oxidized to dehydroascorbic acid. The specific reaction can be derived from the following formula:

[0019] Meanwhile, dehydroascorbic acid precipitates at the bottom of the second pickle processing tank 11, and nitrogen or nitric oxide is generated and can be discharged. The residual liquid inside the second pickle processing tank 11 is filtered and purified by a purification mechanism.

[0020] The desalination mechanism includes activated carbon filter rods 3, ceramic filter rods 4, and fiber filter rods 5 disposed inside the fixed frame 2.

The brine flows through the first transmission pipe 6 to the activated carbon filter rod 3 for salt filtration, and then flows to the ceramic filter rod 4 for further salt filtration. After filtration, it flows to the fiber filter rod 5 for further filtration, performing multiple desalination filtration. Finally, the fiber filter rod 5 discharges the filtered water back into the first pickle processing tank 10.

[0021] The activated carbon filter rod 3 has a first connecting pipe 7 that is connected to the ceramic filter rod 4 on one side, and the ceramic filter rod 4 has a second connecting pipe 8 that is connected to the fiber filter rod 5 on one side, and the fiber filter rod 5 has a third connecting pipe 9 that is connected to the sixth transmission pipe 27 on one side.

A pipe head 15 is connected between the second transmission pipe 14 and the first booster pump 13, and the first booster pump 13 is equipped with a first mounting base 12 for fixing it on the support platform 1. Thus, the water source treated by the desalination treatment mechanism can be discharged back into the first pickled vegetable processing tank 10 through the first booster pump 13.

[0023] The second booster pump 18 is provided with a fifth transmission pipe 26 connected to the first transmission pipe 6, and the other end of the fifth transmission pipe 26 is connected to a third transmission pipe 16 connected to the second booster pump 18.

The other end of the fourth transmission pipe 22 is connected to the second pickle processing tank 11.

[0025] The fourth transmission pipe 22 is equipped with a third booster pump 21 connected to the second pickle processing tank 11. The third booster pump 21 is also equipped with a fourth connecting pipe 19 connected to the second pickle processing tank 11. Furthermore, the third booster pump 21 is equipped with a third mounting base 20 that fixes it to the support platform 1. Through the cooperation between the third booster pump 21 and the fourth transmission pipe 22, the nitrite removal solution inside the second pickle processing tank 11 is transmitted to the ion exchange resin filter rod 23, the first reverse osmosis membrane filter rod 24, and the second reverse osmosis membrane filter rod 25 for filtration.
