Embodiment 1

[0032] Embodiment 1 A kind of food preservation box

[0033] As shown in the figure, the food fresh-keeping box of the present invention includes a box body 1, a box cover 2 sealingly fitted with the box body 1, and an airtight storage chamber 3 formed by combining the box body 1 and the box cover 2, the box body 1 and Cover 2 can be as Figure 1-3 snap-fit ​​connection as shown, or as Figure 5-8 Hinged as shown, of course, the combination between the box body 1 and the box cover 2 of the food preservation box of the present invention is not limited to the above two, but also can be such as threaded connection, buckle connection and other matching methods; in order to strengthen the box body 1 and For the sealing performance between the box cover 2, a protrusion corresponding to the shape of the opening of the box body 1 can be provided on the lower surface of the box cover 2. Of course, a rubber pad can also be provided on the fastening connection surface of the box body 1 ...

Embodiment 2

[0039] Embodiment 2 food preservation method

[0040] The present invention provides a fresh-keeping method based on the above-mentioned food fresh-keeping box, comprising the following steps:

[0041] S1) food is packed into the storage chamber 3 of the fresh-keeping box body 1, and the lid 2 is covered and sealed;

[0042] S2) the air extraction hole A5 on the casing (1) and the case cover 2, the air extraction hole B6 and the air extraction hole C7 are connected with the air extraction equipment; When pumping air, the pumping hole A5, the pumping hole B6 and the pumping hole C7 are pumped together. The purpose of doing this is to keep the air pressure in the hollow interlayer of the box body 1 and the box cover 2 and the air pressure in the storage room in balance, so that the box body 1 and the box cover 2 are kept in balance. The inner layer of the case cover 2 will not independently bear the atmospheric pressure of the storage chamber 3 during pumping, and after the pum...

Description

technical field [0001] The invention relates to a food fresh-keeping box and a fresh-keeping method of the food fresh-keeping box. Background technique [0002] The prior art generally adopts deoxygenation and freezing technology in food preservation. The deterioration or rot of most fresh fruits, vegetables, meat and cooked food is basically related to oxygen. Therefore, oxygen removal technology is an eternal topic in the field of food preservation. Nowadays, oxygen removal mainly adopts combustion and air extraction to remove oxygen. [0003] The Chinese patent with the application number 200410067402.X discloses a food preservation method and a fresh-keeping cold storage. It adopts the method of combustion deoxygenation to deoxygenate the cold storage in a cycle, and to refrigerate and humidify the food stored in the warehouse. Although the preservation problem can be solved to a certain extent, no matter which method is used for combustion in the process of air circula...
