Embodiment 1

[0030] The fresh-keeping and anti-corrosion device described in this embodiment is used for keeping live fish fresh.

[0031] Such as figure 1 As shown, it includes a rigid shell 1, a sealed outer cover 9, an airtight and waterproof sealed inner tank 2, and a pressure gauge 10 can be added as required; the inner tank 2 includes a flexible inner tank body and a rigid sealed inner cover 5 And the upper and lower support members 6,3, and the inner cover 5 are respectively provided with check valves 8,7 for exhaust and air intake; the rigid shell 1 is screwed to the flexible liner 2 through the upper support member 6 at the top, The lower part of the rigid shell 1 is provided with a height-adjustable slot 4, which cooperates with the lower support 3 of the flexible liner 2 to realize the adjustability and fixation of the rigid shell 1 and the flexible liner 2 at the bottom.

[0032] When using this device to keep fish fresh, follow the steps below:

[0033] According to the shap...

Embodiment 2

[0039] The fresh-keeping and anti-corrosion device described in this embodiment is used for fresh-keeping of frozen meat products.

[0040] Structurally, a thermal insulation layer is installed between the inner tank and the outer shell of the device, and the rest are the same as in Embodiment 1.

[0041] According to the characteristics of frozen meat products, the method for implementing fresh-keeping is different from Example 1, and its fresh-keeping method is as follows:

[0042] According to the shape of the frozen meat to be kept fresh, non-toxic plastic or foamed plastic for food packaging can be selected as the inner container body material;

[0043] Place the liner body in the rigid shell, determine the proper position and fix the upper and lower parts respectively;

[0044] Put the frozen meat into the inner tank, add an appropriate amount of dry ice according to the length of storage and transportation, and press the lid to rigidly seal the inner cover 4;

[0045]...

Embodiment 3

[0048] The fresh-keeping antisepsis device described in this embodiment is used for fresh-keeping of fresh fruits and vegetables, and the selection of the sealed inner tank is different from that of Embodiment 2 in structure, and the rest of the structure is the same as that of Embodiment 2.

[0049] According to the characteristics of fresh-keeping fruits and vegetables, before fresh-keeping storage and transportation, firstly carry out sorting and sterilization treatment, and then use the device to carry out fresh-keeping storage and transportation. The method is as follows:

[0050] According to the morphological characteristics of fresh fruits and vegetables, non-toxic plastics or foamed plastics for food packaging are selected as the inner tank body material; stretchable, foldable and nested rigid waterproof inner tanks can also be used, such as figure 2 , image 3 shown.

[0051] Place the liner body in the rigid shell, determine the proper position and fix the upper a...

Abstract

The invention relates to a preservation and antisepsis device and an application method thereof. The device comprises a housing and a liner, and is characterized in that the housing has a rigid structure and the liner has a sealing structure. The liner comprises a liner body and a rigid sealing cover; wherein, the sealing cover is provided with a scavenging air valve; the liner realizes a movable connection of flexible assembly and disassembly with the upper part or the upper and the lower parts of the housing through connecting parts. As the device combines the rigid housing with the sealed liner, the assembly and disassembly are flexible and the device can be repeatedly used; based on the morphological and ecological characteristics of the preservation and antisepsis object, different protective medium can be selected, therefore, the device has the advantages of good preservation and antisepsis effect, moderate cost, high efficiency and environmental friendliness. The device has wide applicability, which can be widely applied to industry, agriculture, fishery and pharmaceutical chemical, as well as tourism and entertainment industries and daily household, thus ensuring huge market potential.

Description

technical field [0001] The invention relates to a container providing a special environment for the contents, in particular to a fresh-keeping and anti-corrosion device and a fresh-keeping method thereof. Background technique [0002] The application of fresh-keeping and anti-corrosion devices is very common, widely used in industry, agriculture, fishery, medicine, chemical industry and daily household. To fresh-keeping cabinets, fresh-keeping warehouses and various supporting facilities, etc.; from the analysis of its principle, it is nothing more than the use of low-temperature refrigeration or freezing, drying and dehydration, vacuum isolation or inert gas, inert gas or neutral liquid isolation, etc. [0003] The existing simple fresh-keeping methods such as plastic wrap are mostly one-time use, which is not conducive to environmental protection, and is not convenient for storage and transportation. Even for short-distance transportation, additional packaging is required,...
