[0003] For example, the rice fermentation system for brewing rice wine disclosed in CN215365662U includes a fermentation body, a vat wall fixedly installed on the top of the fermentation body, a fermentation cover installed on the top of the vat wall, a support plate fixedly installed on the bottom of the vat wall, a limiting component to prevent the fermentation cover from falling off, a releasing component to release the limiting component of the locking block, and a resetting component to release the clamping block from clamping the fermentation cover. The limiting component and the releasing component are provided on the support plate. When the fermentation cover moves onto the fermentation body, the limiting component of the locking block can be released, so that the clamping block can adhere the fermentation cover to the vat wall under the action of the first spring.
[0004] As mentioned above, the sealing structure of the jar lid and the jar body is relatively complex, requiring multiple steps to complete the sealing operation, which increases the labor intensity of the operators. At the same time, the sealing effect of the jar lid and the jar body is poor, which allows external air, impurities and microorganisms to enter between the jar lid and the jar body, affecting the quality and flavor of the rice wine. Utility Model Content
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a rice fermentation system for brewing rice wine that improves the sealing effect, has a simple sealing structure, and is easy to operate.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0026] like Figures 1 to 4 As shown, the rice fermentation system for rice wine brewing includes a fermentation tank body 1, a tank mouth wall 2 fixedly installed on the top of the fermentation tank body 1, and a fermentation tank cover 3 placed on top of the tank mouth wall 2. The tank mouth wall 2 seals the fermentation tank body 1 to prevent external air, impurities and microorganisms from entering the fermentation environment and affecting the quality and flavor of the rice wine.
[0027] The cylinder cover 3 is used to seal the cylinder opening wall 2 of the cylinder body 1, creating a relatively closed and stable fermentation environment. The cylinder cover 3 is equipped with a cover body 4, which includes an upper sealing plate 5 and a lower sealing plate 6. The diameter of the upper sealing plate 5 and the lower sealing plate 6 are the same. The diameter of the upper sealing plate 5 and the lower sealing plate 6 are both larger than the diameter of the cylinder cover 3, which is larger than the diameter of the cylinder opening wall 2.
[0028] First, the lower sealing plate 6 is fitted onto the cylinder bore wall 2. Then, the upper sealing plate 5 is placed above the cylinder head 3, with the cylinder head 3 completely inside the chamber 13 on the upper sealing plate 5. Next, the upper sealing plate 5 and the lower sealing plate 6 are simultaneously pressed towards their center, causing the annular protrusion 11 of the lower sealing plate 6 to engage and fix within the annular groove 10 of the upper sealing plate 5. At this point, the lower sealing plate 6 and the outer wall of the cylinder bore wall 2 are in close contact, and the sealing coating is tightly adhered to the inner wall of the chamber 13. The sealing coating is made of thermoplastic resin and has excellent sealing performance. Sealing strips 15 are installed on both the inner wall of the annular groove 10 and the outer wall of the annular protrusion 11. The sealing strips 15 are respectively attached and fixed to the inner wall of the annular groove 10 and the outer wall of the annular protrusion 11. The sealing strips 15 are made of rubber to better prevent the entry of external air, impurities, and microorganisms.
[0029] The positioning rod 8 first passes through the through hole 12 on the upper cover plate 5 into the chamber 13, then through the through hole 12 on the lower cylinder cover 3 to the space between the lower cylinder cover 3 and the lower cover plate 6, and then through the through hole 12 on the lower cover plate 6. Then the cap 9 is placed below the lower cover plate 6, and one end of the positioning rod 8 is inserted into the insertion hole 14 on the cap 9 and pressed to make one end of the positioning rod 8 engage and fix with the insertion hole 14. Because the other end of the positioning rod 8 has a fixing rod, the diameter of the fixing rod is larger than the diameter of the positioning rod 8 and the through hole 12. When the positioning rod 8 and the cap 9 are fixed, the fixing rod is attached to the upper cover plate 5, and external air, impurities and microorganisms will not enter the space between the upper cover plate 5 and the lower cover plate 6 through the through hole 12, thus achieving a sealing effect.
[0030] Working principle: The upper sealing plate 5 is on the cylinder head 3, and the lower sealing plate 6 is fitted on the outside of the cylinder body 1. The upper sealing plate 5 and the lower sealing plate 6 are fixed by plugging. The cylinder head 3 is set to reduce the entry of external air, impurities and microorganisms from the cylinder body 1. Through the upper sealing plate 5 and the lower sealing plate 6, external air, impurities and microorganisms are prevented from entering between the cylinder head 3 and the cylinder body 1. The double sealing enhances the sealing effect. Then, the connecting rod 7 passes through the upper sealing plate 5, the cylinder head 3 and the lower sealing plate 6 respectively. Finally, the connecting rod 7 is engaged and fixed with the cap 9. Through the cooperation of the upper sealing plate 5, the lower sealing plate 6 and the connecting rod 7, the stability between the upper sealing plate 5, the cylinder head 3 and the lower sealing plate 6 is strengthened, so the sealing structure is simple and the operation is convenient.
[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any ordinary changes and substitutions made by those skilled in the art within the scope of the technical solution of the present utility model should be included within the protection scope of the present utility model.
