Description

Technical field

[0001] The present utility model relates to the technical field of a fermentation sealing vessel, specifically to a fermentation sealing vessel. State of the art

[0002] In agriculture, the production of some foods, such as Chinese sauerkraut, requires fermentation. A plastic barrel is often used as a fermentation vessel, typically fitted with a threaded lid and an air vent to allow fermentation gases to escape. However, practical experience has shown that a threaded lid alone is not sufficiently airtight. Furthermore, after prolonged use, crystallization can occur inside the air vent, causing an inner membrane to expand. This eventually leads to the inner membrane being open, further reducing the seal and allowing external gases to easily enter the barrel, thus disrupting the fermentation process. Disclosure of the utility model

[0003] The present utility model aims to provide a fermentation sealing vessel to solve the aforementioned problem posed in the prior art.

[0004] To solve the aforementioned problem, the present utility model provides the following technical solution: A fermentation sealing vessel of the present utility model, comprising a vessel body, at the head end of which a sealing lid and an outer lid are provided, a lid recess is provided on the sealing lid in which a sealing disc is inserted, the head end of the vessel body is snapped into the lid recess to abut the sealing disc, the outer lid presses the surroundings of a head part of the sealing lid and is threaded in connection with the vessel body; A gas leakage head is provided on the sealing lid; one part of the gas leakage head is formed in the shape of a conical platform, and a gas leakage opening is located on a conical surface; the gas leakage head is enclosed by a soft rubber hose.

[0005] As an improvement, a concave platform is provided on the sealing lid; when stacking the barrel body, one end can be inserted into the concave platform.

[0006] The advantage of the present utility model over existing technology is as follows: The barrel body is screwed tightly to the outer lid, which in turn presses the sealing lid firmly. This, in turn, further presses the end of the barrel body firmly against the sealing disc, thus reinforcing the sealing effect. During fermentation, the air pressure inside the barrel body increases, the gas is released through the gas leakage opening of the gas leakage head, and the soft rubber tube can be pushed off by the air pressure, thus reducing the pressure inside the barrel body and preventing expansion. External gas cannot enter the gas leakage opening and therefore cannot affect the fermentation process inside the barrel body because the gas leakage head is tightly enclosed by the soft rubber tube. Explanation of the illustrations

[0007] To more clearly explain the technical solution in exemplary embodiments of the present utility model or the existing technology, the following are a brief overview of the illustrations required in the exemplary embodiments or in the description of the existing technology. Obviously, the illustrations presented below are only some, not all, of the structural diagrams of the present utility model. Fig. is a structural diagram of a fermentation tank of the present utility model. Fig. is a sectional view I of a fermentation sealing vessel of the present utility model. Fig. is a sectional view II of a fermentation sealing vessel of the present utility model. Fig. is a magnified view of a point A in Fig. . Fig. is a magnified view of a point B in Fig. .

[0009] The technical solution in the embodiments of this utility model is clearly and completely described below in conjunction with the illustrations in those embodiments. Obviously, the described embodiments are only part of the embodiments of this utility model and not the entirety of them. All other embodiments that a person skilled in the art could have obtained without inventive effort based on the embodiments specified in this utility model fall within the scope of protection of this utility model.

[0010] In the description of the embodiment of the present utility model, it must be explained that the directional and positional relationships indicated by the terms "center," "top," "bottom," "left," "right," "vertical," "horizontal," "inside," "outside," etc., refer to the directional and positional relationships depicted in the illustrations or to the usual directional and positional relationships when using the utility model product. This serves only to facilitate the presentation of the present utility model and to simplify the description. Instead of indicating or suggesting that the referred-to devices or components must have a specific orientation, be designed and operated in a specific direction, and therefore cannot be understood as a limitation of the present utility model.

[0011] Furthermore, the terms "first," "second," "third," etc., are used solely for the purpose of distinguishing the representation and should not be interpreted as indicating or suggesting relative importance. Moreover, the appearance of terms such as "horizontal," "vertical," or "hanging" does not imply that the component is perfectly horizontal or hanging, but may be slightly inclined. For example, "horizontal" simply means that the direction is more horizontal relative to "vertical"; this does not mean that the structure must be completely horizontal, but may be somewhat inclined.

[0012] In the description of the present utility model, the terms “several”, “some” represent at least two.

[0013] The description of the embodiments of this utility model must further explain that the terms "provided for," "arranged," "connected," or "connection" are to be understood in a general sense, e.g., it may be a permanent connection, a detachable connection, or a connection as a whole; it may be a mechanical connection or an electrical connection; it may be a direct connection or an indirect connection through an intermediate medium or an internal connection between two components, unless explicitly prescribed and limited otherwise. For the person skilled in the art in the field, the specific meaning of the aforementioned terms in this utility model may be understood differently depending on the circumstances.

[0014] Combined with Fig. until Fig. In the present embodiment, a fermentation sealing vessel is explained in detail.

[0016] A concave platform (9) is provided on the sealing lid (2); when stacking the drum body (1), one lower end can be inserted into the concave platform (9). This facilitates stacking and storage of the drum body (1).

[0017] During the process, the foodstuffs, Chinese sauerkraut, and other substances are placed in the barrel body (1) for fermentation; then the sealing lid (2) is closed, and the head end of the barrel body (1) is pressed down by the sealing disc (5), as shown in Fig.As shown, the outer lid (3) is then closed, the barrel body (1) is screwed on tightly, the outer lid (3) presses the sealing lid (2) firmly, and furthermore, the sealing disc (5) presses the head end of the barrel body (1) firmly, thus increasing the sealing effect. During fermentation, the air pressure inside the barrel body (1) is increased, the gas is released through the gas leakage opening (7) of the gas leakage head (6) (the soft rubber tube (8) may be pushed off by the air pressure), so that the pressure inside the barrel body (1) is reduced and expansion is thus prevented, the outside gas cannot enter the gas leakage opening (7) and cannot affect the fermentation inside the barrel body (1) because the gas leakage head (6) is tightly enclosed by the soft rubber tube (8).
