Description

Technical Field

[0001] The present invention relates to the technical field of food deoxidation, and particularly to a household deoxidation assembly, a household deoxidation device, and a household deoxidation method. Background Art

[0002] Iron powder used as a deoxidizer is a chemical product widely used in multiple fields. Its main function is to reduce the oxygen concentration in the environment through chemical reactions, thereby playing a role in protecting items. For example, by reducing the oxygen concentration in food packaging, it can prevent food from discoloring, deteriorating, and oil rancidity due to oxidation, so as to improve the quality or shelf life of food.

[0003] As the core component of the deoxidizer, the working principle of iron powder is mainly based on the oxidation-reduction reaction between iron powder and oxygen. Although this oxidation-reduction reaction is only between iron powder and oxygen, the presence of water is necessary in this reaction. This is because the moisture inside the deoxidizer can help iron powder react with oxygen. When the iron powder in the deoxidizer comes into contact with oxygen, the moisture can promote the oxidation process of iron powder, generating iron oxide and releasing hydrogen. That is, the presence of water for the iron powder in the deoxidizer is not a direct chemical reaction requirement, but to promote the reaction between iron powder and oxygen, so as to achieve the deoxidation effect. However, if iron powder and water are combined before deoxidation, the presence of water is extremely unfavorable for the storage of the deoxidizer and greatly shortens the service life.

[0004] In addition, current household deoxidizers all use conventional food deoxidizers. Such deoxidizers will produce a deoxidation reaction as soon as they come into contact with air, and their deoxidation performance continuously decreases over time. Currently, these deoxidizers are all packaged in multiple tablets and heat-sealed for storage. When used at home, a small amount of deoxidizer is taken out of the bag after opening, and the remaining deoxidizer needs to be put back into the bag and heat-sealed again for use next time. A heat-sealing machine is required, which is very inconvenient for household scenarios. Moreover, the performance of the deoxidizer will be lost every time the bag is opened, which has a great impact on the use effect.

[0005] Therefore, how to improve the service life and effect of household deoxidizers and enhance their convenience is a difficult problem that the industry needs to solve. Summary of the Invention

[0007] Based on the above problems, the purpose of the present invention is to provide a household deoxidation assembly, a household deoxidation device, and a household deoxidation method. The household deoxidation assembly can greatly improve the storage performance and use effect of the deoxidizer, and is convenient for household deoxidation, which can be opened at any time when needed.

[0008] To achieve the above object, a first aspect of the present invention provides a household deoxidation assembly, which includes a container for accommodating a deoxidation component and a leak-proof nozzle communicating with the opening of the container. The leak-proof nozzle includes a body and a plug. The body has a hollow structure and one end is connected to the container, and the opposite end is detachably connected to the plug. A limiting plate is provided inside the body, and a first through hole communicating the container and the plug is opened on the limiting plate. A first filter paper, a sponge sheet and a second filter paper are sequentially arranged on the side of the limiting plate away from the container inside the body. A second through hole is opened on the plug, and the deoxidation component is an iron powder deoxidant containing a water-absorbing resin.

[0009] In the household deoxidation assembly of the present invention, the iron powder deoxidant containing a water-absorbing resin is placed in a container. The water-absorbing resin has the function of absorbing water vapor for drying, and can keep the iron powder deoxidant in an anhydrous state for a long time, achieving the effect that the iron powder deoxidant will not fail even after long-term storage. The first filter paper, the sponge sheet and the second filter paper can prevent the iron powder deoxidant from escaping from the container during transportation, storage or use, and at the same time do not affect the oxygen from entering the container through the body from the outside and being reacted by the iron powder deoxidant. When deoxidation is required, a water-containing substance is input into the leak-proof nozzle from the outside through the second through hole, and the water-containing substance enters the container through the leak-proof nozzle and mixes with the iron powder deoxidant to cause the iron powder to undergo a deoxidation reaction, which is convenient and immediate for deoxidation.

[0010] As a technical solution of the present invention, by weight, the iron powder deoxidant contains 40-90 parts of iron powder, 0.5-5.0 parts of water-absorbing resin, 0.5-2.5 parts of activated carbon, 3-10 parts of silicon dioxide and 0-4 parts of other functional components.

[0011] As a technical solution of the present invention, the water-absorbing resin is a high molecular water-absorbing resin made of an acrylic graft copolymer, and the particle size is 30-150 mesh.

[0012] As a technical solution of the present invention, the container is a filling bag or a filling bottle, and the leak-proof nozzle is tubular and integrally formed with the limiting plate.

[0013] As a technical solution of the present invention, the outer diameters of the first filter paper, the sponge sheet and the second filter paper are the same as the inner diameter of the leak-proof nozzle.

[0014] As a technical solution of the present invention, the body is provided with an external thread, and the plug is provided with an internal thread. The detachable connection between the body and the plug is achieved by the connection of the external thread and the internal thread.

[0015] In a second aspect of the present invention, a household deoxidation device is provided, which includes the aforementioned household deoxidation assembly and a reservoir for holding saline solution. The reservoir transports the saline solution to the container through the second through hole. By separately arranging the household deoxidation assembly and the reservoir, the iron powder deoxidant and the saline solution are separated and mixed together when needed, which can keep the iron powder deoxidant in an anhydrous state for a long time and extend the service life of the iron powder deoxidant.

[0016] As a technical solution of the present invention, the reservoir is a syringe.

[0017] As a technical solution of the present invention, the mass ratio of the saline solution to the iron powder is 3-20:40-90.

[0018] In a third aspect of the present invention, a household deoxidation method is provided. In the container of the aforementioned household deoxidation device, the deoxidation component is placed. After assembling the first filter paper, the sponge sheet and the second filter paper in the body, the plug is fixed. The saline solution in the reservoir is transported into the container and mixed with the deoxidation component for deoxidation. This household deoxidation method is convenient to operate and has a better deoxidation effect. Description of the Drawings

[0022] The household deoxidation device of the present invention includes a household deoxidation assembly and a reservoir. The household deoxidation assembly is used to store the deoxidation component (iron powder deoxidant), and the reservoir is used to store the saline solution. The reservoir can be a conventional container for holding liquids or a syringe, especially a syringe which is more convenient for transporting the saline solution into the container of the household deoxidation assembly.

[0023] The iron powder deoxidizer contains 40 - 90 parts of iron powder, 0.5 - 5.0 parts of water-absorbing resin, 0.5 - 2.5 parts of activated carbon, 3 - 10 parts of silicon dioxide, and 0 - 4 parts of other functional components. The iron powder can be, but is not limited to, 40 parts, 45 parts, 50 parts, 55 parts, 60 parts, 65 parts, 70 parts, 75 parts, 80 parts, 85 parts, 90 parts, and the iron powder is used for deoxidation. The water-absorbing resin can be, but is not limited to, 0.5 parts, 1.0 parts, 1.5 parts, 2.0 parts, 2.5 parts, 3.0 parts, 3.5 parts, 4.0 parts, 4.5 parts, 5.0 parts. The water-absorbing resin is a high molecular water-absorbing resin made of acrylic graft copolymer, with a particle size of 30 - 150 mesh. The water-absorbing resin can keep the iron powder deoxidizer in an anhydrous state for a long time, achieving the effect that the iron powder deoxidizer will not fail during long-term storage. The activated carbon can be, but is not limited to, 0.5 parts, 1.0 parts, 1.5 parts, 2.0 parts, 2.5 parts. The activated carbon can adsorb moisture and oxygen in the surrounding environment, providing more opportunities for the iron powder to contact with oxygen and water, helping the deoxidizer consume oxygen better and extending the shelf life of products such as food. The silicon dioxide can be, but is not limited to, 3 parts, 4 parts, 5 parts, 6 parts, 7 parts, 8 parts, 9 parts, 10 parts. The silicon dioxide mainly plays a role in filling, making the deoxidation reaction easier to proceed. The other functional components are 0 - 4 parts. As an example, the other functional components can be, but are not limited to, 0 parts, 1 part, 2 parts, 3 parts, 4 parts. The other functional components can be a dispersant and / or a bactericide. The dispersant can be a conventional solid dispersant to disperse the iron powder, water-absorbing resin, activated carbon, and silicon dioxide evenly. The bactericide can be a conventional solid bactericide to remove the bactericide in the container, preventing the iron powder deoxidizer from failing due to mildew. The mass ratio of brine to iron powder is 3 - 20:40 - 90. As an example, the mass ratio of the two can be, but is not limited to, 3:40, 3:60, 3:90, 8:40, 8:60, 8:90, 10:40, 10:70, 10:90, 15:45, 15:75, 15:85, 20:48, 20:65, 20:85. Using brine can not only provide water for the deoxidation reaction, but also sodium chloride can form a primary battery to improve the deoxidation efficiency.

[0024] The structure of the household deoxidation assembly of the present invention can be as Figure 1 shown. The household deoxidation assembly 100 includes a container 10 for accommodating the deoxidation components and a leak-proof nozzle 30 communicating with the opening of the container 10.

[0025] The container 10 can be a filling bag or a filling bottle, which can be transparent to observe the mixing and deoxidation of the deoxidation components in the container 10. The container 10 can integrally form a leak-proof nozzle 30 at the opening, or can be fixedly connected to the leak-proof nozzle 30 in a split manner.

[0026] The leak-proof nozzle 30 includes a body 31 with a hollow structure and a plug 33 detachably connected to the body 31. One end of the body 31 is connected to the container 10, and the other relatively end is detachably connected to the plug 33. The body 31 can be tubular and integrally formed by extending from the opening of the container 10, or can be fixedly connected by means of hot melting, bonding, welding, etc. A limiting plate 311 is provided inside the body 31, and a first through hole 311a communicating with the container 10 and the plug 33 is opened in the limiting plate 311. The limiting plate 311 can be integrally formed with the leak-proof nozzle 30. Inside the body 31, a first filter paper sheet 313, a sponge sheet 315 and a second filter paper sheet 317 are sequentially arranged on the side of the limiting plate 311 away from the container 10. The limiting plate 311 can limit the positions of the first filter paper sheet 313, the sponge sheet 315 and the second filter paper sheet 317 in the body 31. When injecting brine with a syringe, the syringe pierces through the first filter paper sheet 313, the sponge sheet 315 and the second filter paper sheet 317, and the brine can be quickly input into the interior of the container 10. Even if the first filter paper sheet 313 and the second filter paper sheet 317 are pierced, the sponge sheet 315 sandwiched between the two can prevent the iron powder deoxidizer from escaping from the pierced position due to its own contraction effect. The outer diameters of the first filter paper sheet 313, the sponge sheet 315 and the second filter paper sheet 317 are the same as the inner diameter of the body 31 of the leak-proof nozzle 30.

[0027] A second through hole 331 is opened on the plug 33. The body 31 is provided with an external thread 319, and the plug 33 is provided with an internal thread 333. The detachable connection between the body 31 and the plug 33 is realized by the connection of the external thread 319 and the internal thread 333.

[0028] For the household deoxidation device of the present invention, the plug 33 can be first opened, the deoxidation components can be poured into the body 31, then the first filter paper sheet 313, the sponge sheet 315 and the second filter paper sheet 317 are sequentially stacked on the side of the limiting plate 311 close to the plug 33, and then the plug 33 is tightened. When deoxidation is required, a syringe is used to pierce through the first filter paper sheet and the second filter paper sheet 317, and the brine is conveyed into the container 10 to be mixed with the deoxidation components for deoxidation.

[0029] Furthermore, the household deoxidation device of the present invention can be used for deoxidation testing.

[0031] The first deoxidizing component consists of 74 g of reduced iron powder, 3 g of water-absorbing resin, 2 g of activated carbon, and 6 g of silicon dioxide. After weighing each material according to this ratio and mixing them evenly, 5 g is taken and put into a container. Then, the plug is tightened and 0.75 mL of 10 wt.% brine is injected with a syringe. The oxygen removal amount of the first deoxidizing component within 4 days is detected by the graduated cylinder method. The results are shown in Table 1. The household deoxidizing assembly is stored at room temperature in the open air. At regular intervals, 0.75 mL of 10 wt.% brine is injected with a syringe according to the same operation, and the oxygen removal amount of the first deoxidizing component within 4 days is detected by the graduated cylinder method. The results are shown in Table 1.

[0032] Table 1 Results of detecting the deoxidation performance using the first deoxidizing component

[0033] Time 1d 2d 3d 4d Oxygen removal amount / mL after storage for 0 d 560 940 1150 1250 Oxygen removal amount / mL after storage for 1 d 550 960 1150 1240 Oxygen removal amount / mL after storage for 60 d 540 955 1150 1245 Oxygen removal amount / mL after storage for 120 d 550 950 1140 1235 Oxygen removal amount / mL after storage for 180 d 530 940 1130 1215

[0034] From the results in Table 1, it can be seen that after the household deoxidizing assembly is stored at room temperature in the open air for 180 days, it still has a high oxygen removal amount.

[0035] Test 2: Detecting the deoxidation performance using the second deoxidizing component in the presence of other media

[0036] The second deoxidizing component consists of 73 g of reduced iron powder, 4 g of water-absorbing resin, 2 g of activated carbon, and 10 g of silicon dioxide. After weighing each material according to this ratio and mixing them evenly, 5 g is taken and put into a container. Then, the plug is tightened and 0.7 mL of 10 wt.% brine is injected with a syringe, and at the same time, 1 mL of 56° liquor is injected. The oxygen removal amount of the first deoxidizing component within 4 days is detected by the graduated cylinder method. The results are shown in Table 2. Additionally, a same household deoxidizing assembly that has been mixed with brine and liquor is put into a 1000 mL PE self-sealing bag, sealed, and stored at room temperature. The gas concentration inside the bag is detected with an instrument. The results are shown in Table 3.

[0041] From the results in Table 2, it can be seen that even in the presence of alcohol interference, it still has good deoxidation performance. From the results in Table 3, it can be seen that the inside of the PE self-sealing bag is in an anaerobic state, and the alcohol concentration is high. When the alcohol concentration exceeds 3000 ppm in the anaerobic state, it has an effective bactericidal and antibacterial effect, indicating that the household deoxidizing device of the present invention can also combine different functional effects according to needs.

[0042] Test 3: Detect the deoxidation performance of food using the second deoxidizing component

[0043] Take the same household deoxidation assembly mixed with brine and white wine in Test 2 and put it into a thick PE self-sealing bag containing 500 g of dried squid. Seal the bag and store it at room temperature. After 180 days, detect the oxygen concentration and alcohol concentration in the self-sealing bag, and observe the appearance change of the dried squid. The results are shown in Table 4.

[0046]

[0047] It can be seen from the results in Table 4 that the household deoxidation assembly of the present invention has a good deoxidation effect on food. The purchased food does not need to be refrigerated in the refrigerator, and the quality of the food can be guaranteed even when placed at room temperature.
