[0002] As a traditional fermented food, the control of the fermentation environment is particularly important during the production process of fermented bean curd. As the main equipment for fermentation tank production, the sealing performance of the fermentation tank directly affects the fermentation quality and safety of fermented bean curd. However, the sealing structure of traditional fermentation tanks often has problems such as poor sealing effect and inconvenient operation, which makes it difficult to meet the needs of modern production.

[0023] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0024] A sealing structure of a fermented bean curd fermentation tank comprises a fermentation tank 1 and a top cover 3 hinged to the top thereof by a hinge 6, an annular sealing chamber 12 is provided at the top of the fermentation tank 1, an annular plate 33 inserted into the annular sealing chamber 12 is fixedly installed below the top cover 3, an oil tank 2 is fixedly installed on the outer wall of the fermentation tank 1, an oil inlet pipe 21 and an oil outlet pipe 20 of the oil tank 2 are both connected to the inside of the annular sealing chamber 12, an oil pump 200 is installed on the oil outlet pipe 20, an oil inlet pipe valve 210 is installed on the oil inlet pipe 21, a discharge pipe 14 is installed at the bottom of the fermentation tank 1, a discharge pipe valve 15 is installed on the discharge pipe 14, and at least three legs 4 are installed at the bottom of the fermentation tank 1. By arranging the annular sealing chamber 12, the annular plate 33, the oil tank 2, the oil inlet pipe 21, the oil outlet pipe 20, the oil pump 200 and other components, the fermentation tank 1 is effectively sealed by oil sealing, the entry of external air and impurities is prevented, and the quality and safety of fermented bean curd fermentation are guaranteed. At the same time, the sealing structure also has the advantages of simple structure, convenient operation and good sealing effect.

[0025] As a preferred embodiment of the present invention, an outer sealing gasket 13 is fixedly installed inside the annular sealed chamber 12 on both the inner and outer sides of the annular plate 33, and an inner sealing gasket 34 is fixedly connected to the outer ring wall of the annular plate 33. By arranging the outer sealing gasket 13 and the inner sealing gasket 34 inside the annular sealed chamber 12, the sealing effect is further enhanced, the gas and liquid inside the fermentation tank 1 are prevented from leaking, and the fermentation efficiency is improved.

[0026] As a preferred embodiment of the present invention, an L-shaped stopper 30 is integrally formed at one end of the top cover 3 away from the hinge 6, and a connecting block 10 used in conjunction with the stopper 30 is integrally formed on the outer wall of the fermentation tank 1, and the stopper 30 and the connecting block 10 are connected by a stopper pin 32. The stopper 30, the stopper pin 32 and the connecting block 10 are provided to connect the end of the top cover 3 away from the hinge 6 to the fermentation tank 1. It should be noted that the stopper pin 32 passes through the stopper block 30 and is threadedly connected to the connecting block 10.

[0027] As a preferred embodiment of the present invention, a pressing rod 31 is welded and fixed on the outer wall of the limiting block 30. This facilitates the operator to open and close the top cover 3, thereby improving work efficiency.

[0028] As a preferred embodiment of the present invention, a glass window 11 is provided on the outer wall of the fermentation tank 1, and the glass window 11 is made of tempered glass, so that the operator can observe the situation inside the fermentation tank 1 at any time, understand the fermentation progress and status in time, and facilitate adjustment and control.

[0029] As a preferred embodiment of the present invention, a liquid level sensor 16 is fixedly mounted on the inner wall of the annular sealing chamber 12, and the liquid level sensor 16 is located above the outer sealing pad 13. The oil level in the annular sealing chamber 12 can be monitored in real time, and when the oil level is too low, the operator is reminded to add sealing oil in time, thereby ensuring the continuity and stability of the seal.

[0030] As a preferred embodiment of the present invention, a gasket 5 is fixedly connected to the top of the fermentation tank 1 and the bottom of the top cover 3, and the two gaskets 5 are directly opposite each other. The sealing between the top of the fermentation tank 1 and the top cover 3 is enhanced, the leakage of gas and liquid is prevented, and the sealing effect is improved.

[0031] As a preferred embodiment of the present invention, a conical depression is provided at the bottom of the fermenter 1, with the bottom pointing to the top of the discharge pipe 14. This makes the discharge smoother, avoids the residue and blockage of the material during the discharge process, and improves the discharge efficiency.

[0032] When the sealing structure of the fermented bean curd fermentation tank of the present invention is used, when the fermentation tank 1 needs to be sealed, the operator first flips the top cover 3 to the top of the fermentation tank 1 through the hinge 6, and inserts the annular plate 33 into the annular sealing chamber 12. At this time, the inner sealing gasket 34 on the outer ring wall of the annular plate 33 is in close contact with the outer sealing gasket 13 in the annular sealing chamber 12, forming a first layer of sealing.

[0033] Next, the operator starts the oil pump 200 and pumps the sealing oil in the oil tank 2 into the annular sealing chamber 12 through the oil outlet pipe 20. The sealing oil accumulates in the annular sealing chamber 12 until it reaches the height of the liquid level sensor 16. At this time, the liquid level sensor 16 monitors the oil level in real time and sends a signal when the oil level is too low to remind the operator to add sealing oil in time.

[0034] After fermentation is completed, especially after a part of the inner sealing gasket 34 is separated from the outer sealing gasket 13, due to the gap between the inner and outer sealing gaskets, the oil inlet pipe valve 210 is opened. At this time, the oil in the annular sealing chamber 12 will flow back to the oil tank 2 through the oil inlet pipe 21. The top cover 3 can be opened after the oil in the annular sealing chamber 12 is discharged from the outer wall.

[0035] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
