Description

Technical Field

[0001] The utility model relates to the technical field of Luzhou-flavor liquor brewing, in particular to a sealing structure for a mash fermentation box. Background Art

[0002] In the traditional wine production industry, traditional mash fermentation tanks have many deficiencies in sealing performance. For example, when a water seal is used, a water tank is usually opened on the side wall of the fermentation tank, water is injected into the water tank, and then a sealing cover is used to seal the fermentation tank. The raised edge of the sealing cover cooperates with the water tank to achieve water sealing. Since the water in the water tank is in contact with the outside world, the mash is easily infected by bacteria, and the sealing water needs to be replaced frequently, which is not easy to clean. Especially when a constant temperature and humidity environment needs to be maintained during the fermentation process, poor sealing will cause oxygen and microorganisms in the outside air to enter the fermentation tank, affecting the fermentation quality and the flavor of the product, and causing certain losses to the finished wine.

[0003] Therefore, how to improve the sealing effect of the mash fermentation box becomes a difficult problem. Utility Model Content

[0004] In order to overcome the existing deficiencies, the technical problem to be solved by the present invention is to provide a sealing structure for a mash fermentation box, which can improve the sealing effect.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] The sealing structure of the mash fermentation box includes a fermentation box and a sealing cover. The fermentation box is placed with its opening facing upward. The side wall of the fermentation box has a water trough. The lower surface of the sealing cover has a water trough connecting portion that cooperates with the water trough. When the sealing cover is placed on the fermentation box, the fermentation box is sealed and connected to the sealing cover through the water trough. It is characterized in that it includes a sealing ring, the sealing ring is located on the periphery of the water trough connecting portion, the sealing ring is fixedly connected to the lower surface of the sealing cover and the central axis of the sealing ring is coaxial with the central axis of the sealing cover. When the sealing cover is placed on the fermentation box, the sealing cover is sealed and fitted with the fermentation box through the sealing ring.

[0007] Furthermore, the sealing ring is a silicone ring.

[0008] Furthermore, the sealing cover is provided with a hanging ring.

[0009] Furthermore, the sink connection portion does not contact the bottom of the sink.

[0010] The beneficial effects of the utility model are:

[0011] By providing a water trough connection on the bottom surface of the sealing cover, which mates with the water trough on the fermentation box, and then providing a sealing ring on its periphery, which seals tightly against the fermentation box, a double sealing effect is achieved. Water in the water trough can fill the tiny gap between the sealing cover and the fermentation box, further strengthening the seal, effectively preventing outside air and microorganisms from entering the fermentation box, and ensuring the purity and stability of the fermentation process.

[0012] The lifting ring design on the sealing cover makes opening and closing more convenient, simple and quick to operate, without the need for complicated tools or excessive manpower, reducing the labor intensity of operators. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 This is a structural diagram of the sealing structure of the mash fermentation box of the present invention;

[0014] Figure 2 This is a schematic structural diagram of the sealing cover of the utility model;

[0015] Marked in the figure are, 1-fermentation box, 2-sealing cover, 3-water tank, 4-sealing ring. DETAILED DESCRIPTION

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] First of all, it should be stated that the "upper", "lower", "inside" and "outside" mentioned in this application only represent relative position relationships, not absolute positions. When the absolute position of the described object changes, the relative position relationship may also change accordingly.

[0018] The sealing structure of the mash fermentation box includes a fermentation box 1 and a sealing cover 2. The fermentation box 1 is placed with its opening facing upward. The side wall of the fermentation box 1 has a water tank 3 with its opening facing upward. The lower surface of the sealing cover 2 has a water tank connecting portion that cooperates with the water tank 3. When the sealing cover 2 is placed on the fermentation box 1, the fermentation box 1 is sealed and connected to the sealing cover 2 through the water tank 3. The sealing cover includes a sealing ring 4. The sealing ring 4 is located outside the water tank connecting portion. The sealing ring 4 is fixedly connected to the lower surface of the sealing cover 2 and the central axis of the sealing ring 4 is coaxial with the central axis of the sealing cover 2. When the sealing cover 2 is placed on the fermentation box 1, the sealing cover 2 is sealed and fitted with the fermentation box 1 through the sealing ring 4.

[0019] By providing a water trough connection on the lower surface of the sealing cover 2, which cooperates with the water trough 3 on the fermentation box 1, and then providing a sealing ring 4 on its periphery, which seals and fits tightly with the fermentation box 1, a double sealing effect is achieved. Water in the water trough 3 can fill the tiny gap between the sealing cover 2 and the fermentation box 1, further enhancing the sealing, effectively preventing outside air and microorganisms from entering the fermentation box, and ensuring the purity and stability of the fermentation process.

[0020] Furthermore, the sealing ring 4 is a silicone ring.

[0021] The sealing ring 4 can also be a sand bag or a water bag, but considering the sealing effect and cost, this solution preferably uses a silicone ring.

[0022] Furthermore, the sealing cover 2 is provided with a hanging ring.

[0023] The lifting ring design on the sealing cover 2 makes opening and closing more convenient, and the operation is simple and quick, without complicated tools or excessive manpower, thereby reducing the labor intensity of the operator.

[0024] Furthermore, the sink connection portion does not contact the bottom of the sink, in order to fill the sink with water and prevent the water from overflowing.

[0025] The technical solutions of the embodiments of the present application are described clearly and completely. The described embodiments are part of the embodiments of the present application and are not limitations of the present utility model. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection of the present application.
