Embodiment 1

[0037] Such as Figure 1-3 As shown, the sealing device for anaerobic fermentation of the present invention includes an outer sealing bag 1 and an inner sealing bag 2, and the inner sealing bag 2 is located inside the outer sealing bag 1. The mouth of the outer sealed bag 1 is sealed by a concave-convex button 4 . The mouth of the inner sealed bag 2 is sealed by a concave-convex button 4 .

[0038] In the present invention, the outer layer structure is an outer sealed bag, and the inner layer structure is an inner sealed bag. The inner sealed bag is used to hold the fermentation raw materials that need to be fermented, and the outer sealed bag is used to encrypt the inner sealed bag, thereby providing double-layer sealing protection, even In the case of leaking air in the inner sealed bag, the outer sealed bag can also prevent the outside air from contacting the fermentation raw material, and the outer sealed bag also has a sealing effect on the fermented raw material; Ferme...

Embodiment 2

[0040] Based on Embodiment 1, the inner sealed bag 2 is a vacuum compression bag, and the inner sealed bag 2 is provided with a vacuum valve 3 . The vacuum valve 3 is close to the mouth of the inner sealed bag 2, and the distance between the vacuum valve 3 and the mouth of the inner sealed bag 2 is 1 / 8 of the total length of the inner sealed bag 2.

[0041] In the present invention, the inner sealed bag uses a vacuum compression bag. After the fermentation raw material is loaded into the inner sealed bag, the air can be pumped outward from the vacuum valve, and the air inside the inner sealed bag can be taken away. The inside of the inner sealed bag is a vacuum environment. It is conducive to anaerobic fermentation; compared with traditional food packaging bags, the vacuum compression bag has a vacuum valve, which is convenient for vacuuming, and the vacuum compression bag can be reused.

[0042] In the present invention, the position of the vacuum valve is close to the mouth ...

Embodiment 3

[0044] Based on the above-described embodiment, the side where the outer sealed bag 1 and the inner sealed bag 2 are located is the top, the outer sealed bag 1 and the inner sealed bag 2 are located on the same side, and the outer wall of the inner sealed bag 2 bottom is in contact with the outer sealed bag. 1 The inner walls of the bottom are glued together.

[0045]The present invention fixes the inner sealed bag inside the outer sealed bag to prevent the inner sealed bag from sliding around inside the outer sealed bag and cause damage to the outer sealed bag; in addition, the outer sealed bag and the inner sealed bag are connected together in the present invention, so that the device has high integrity and can be opened After the outer sealed bag, the outer sealed bag is still connected to the inner sealed bag, and there is no need to store the outer sealed bag specially.

Abstract

The invention discloses a sealing device and method for anaerobic fermentation. The sealing device comprises an outer sealing bag and an inner sealing bag, wherein the inner sealing bag is located inthe outer sealing bag. The sealing method comprises the following step of performing sealing storage on fermentation raw materials by adopting a double-layer sealing structure. According to the invention, the sealing device with the double-layer structure is designed, and the inner-layer structure can be sealed through the outer sealing structure, so that the sealing performance of the whole device is improved; and the double-layer sealing structure solves the problem that in the prior art, a simple food packaging bag is adopted for packaging the fermentation raw materials, so that the sealingperformance is poor.

Description

technical field [0001] The invention relates to an anaerobic fermentation device, in particular to a sealing device and a sealing method for anaerobic fermentation. Background technique [0002] Fermentation refers to the process in which people use the life activities of microorganisms under aerobic or anaerobic conditions to prepare the microbial cells themselves, or direct metabolites or secondary metabolites. Fermentation is sometimes also written as ferment, and its definition varies depending on the occasion of use. The so-called fermentation usually refers to a certain decomposition process of organisms for organic matter. Fermentation is a biochemical reaction that human beings came into contact with earlier, and it is widely used in food industry, biology and chemical industry. [0003] Fermentation technology has now developed into an engineering discipline and an independent industry, covering food fermentation (such as yogurt, cheese, bread, pickled vegetables,...
