Embodiment 1

[0060] This embodiment provides a deoxygenation unit for family food preservation, specifically as figure 1 As shown, it includes a first oxygen removal module 101, a second oxygen removal module 102 and a third oxygen removal module 103 arranged linearly in sequence, the first oxygen removal module 101, the second oxygen removal module 102 and the third oxygen removal module 101 The oxygen module 103 is a hollow box structure filled with iron-based oxygen scavenger, noble metal catalyst and transition metal oxygen scavenger respectively. , and the right sides are provided with a number of ventilation holes 104, and through the ventilation holes 104, the gas circulation inside each deaeration module and between adjacent deaeration modules is realized.

[0061] In this example, the preparation method of the iron-based oxygen scavenger is as follows: 15g of iron powder, 4g of diatomaceous earth, 2g of activated carbon and 3g of sodium chloride are evenly mixed, and then sprayed ...

Embodiment 2

[0064] This embodiment provides a deoxygenation device for family food preservation, its structure is as follows: Figure 2~3 As shown, it comprises an upward opening box body 2, a cover plate 4 and 4 groups of deoxygenation unit box bodies 7 arranged in whole rows inside the box body 2, and the cover plate 4 sealing cover is arranged on the top of the box body 2, except The oxygen unit box body 7 divides the box body 2 into four serpentine passages sealed up and down and connected only at the ends. Each serpentine passage is filled with a deoxygenation unit as shown in Embodiment 1.

[0065] In the deoxygenation unit box body 7, the third deoxygenation module 103 of the previous deoxygenation unit realizes gas communication with the first deoxygenation module 101 of the next adjacent deoxygenation unit, and the first deoxygenation module 101 of the first deoxygenation unit The oxygen module 101, until the oxygen removal unit box body 7 corresponding to the first oxygen remova...

Embodiment 3

[0070] This embodiment provides a method for deoxygenation for family food preservation. The deoxygenation method is carried out using the deoxygenation device shown in Example 2, and specifically includes the following steps: according to the required oxygen concentration, the The air is fed into the box body 2 through any one of the air inlet 201, the air inlet 202, the air inlet 203, and the air inlet 204. The air port 205 is exhausted.

[0071] In the oxygen removal method of this embodiment, the oxygen removal mechanism is: the hydrogen gas generated by the reaction of the iron-based oxygen scavenger with the water and oxygen in the air reacts with oxygen in the first oxygen removal module 101, and the water generated at the same time can increase The humidity of the fresh-keeping cavity, and the transition metal oxygen scavenger can further remove residual oxygen; through the reaction of three oxygen removal modules, the oxygen in the air can be removed as much as possib...

Abstract

The invention discloses a deoxygenation unit, a deoxygenation device and a deoxygenation method for household food preservation. Oxygen module, the first oxygen removal module, the second oxygen removal module and the third oxygen removal module are hollow box-shaped structures filled with iron-based oxygen scavenger, noble metal catalyst and transition metal oxygen scavenger respectively , the left and right sides of the first deaeration module, the second deaeration module and the third deaeration module are provided with a number of ventilation holes, and the ventilation holes are used to realize the inside of the deaeration module and the deaeration module. Gas flow between oxygen modules. The deoxygenation device provided by the invention has a good deoxygenation effect, can further flexibly control the oxygen concentration, and is very suitable for keeping food fresh at home.

Description

technical field [0001] The invention relates to a deoxygenation unit, a deoxygenation device and a deoxygenation method for household food preservation. Background technique [0002] A low-oxygen environment can significantly improve the preservation effect of fresh fruits and vegetables, but there is a lack of deoxygenation methods suitable for household environments, making consumers prone to dehydration and spoilage of fresh fruits and vegetables stored at home. [0003] At present, there are three main methods for separating oxygen from air: ①Cryogenic distillation method, which consumes a lot of energy and is used for cooling; ②Membrane filtration, this method is limited by gas pressure, product life and work efficiency and is not suitable for families. Application; ③Pressure swing adsorption method, the required equipment is huge, and the working noise is huge, so it is not suitable for families. [0004] In addition, the food deoxidizer used in snack food has problem...
