[0002] A fermentation tank refers to a device used for microbial fermentation in industry. Fermentation tanks are widely used in industries such as dairy products, beverages, bioengineering, pharmaceuticals, and fine chemicals. Fermentation tanks are also used in the production process of mulberry fruit wine.
[0003] As the prior art (patent number: CN217398870U) discloses a fermentation tank pressure regulating mechanism, which includes an air pipe installed on the tank body. A pressure gauge is installed on the side of the air pipe. A first stop block is slidably installed in the middle of the sealing rod, and a second stop block is slidably installed on the other side of the sealing rod. A elastic cord is fixedly connected to the lower end of the second stop block. The moving plate and the piston plate are elastically connected by a first spring, and the movable plate is fixedly connected to the inner wall of the collecting box by a second spring.
[0004] In the above application, three elastic structures, namely an elastic cord, a first spring and a second spring, are arranged to cooperate with other structures to achieve the purpose of pressure relief. However, the elasticity of the elastic structure gradually decreases during long-term use. As the elasticity decreases, the pressure relief starts before the internal pressure of the fermentation tank reaches the initial ideal maximum value, thereby affecting the pressure relief effect.

[0024] As Figures 1-5 shown, an adjustable-pressure mulberry fruit fermentation device includes a fermentation tank 1. One end of the top of the fermentation tank 1 is fixedly provided with a connecting seat 2. A ventilation cavity 3 is opened inside the connecting seat 2. The outside of the connecting seat 2 is threadedly connected with an outer shell 4. A plurality of air outlet holes 5 are opened at the end of the outer shell 4. The top of the outer shell 4 is threadedly connected with an adjusting rod 6. A pressing plate 7 is rotatably provided at the bottom of the adjusting rod 6. A blocking block 8 is arranged below the pressing plate 7. The blocking block 8 is arranged in a conical shape. A spring 9 is arranged between the top of the blocking block 8 and the pressing plate 7. One end of the top of the fermentation tank 1 far from the outer shell 4 is fixedly provided with a feeding pipeline 14, and a sealing cover 15 is arranged on the feeding pipeline 14;
[0025] Through the threaded connection between the outer shell 4 and the connecting seat 2, it is convenient to remove the outer shell 4 and replace the spring 9 inside it. When the pressure inside the fermentation tank 1 is too high, the gas inside the fermentation tank 1 enters the ventilation cavity 3, and jacks up the blocking block 8 upward. The blocking block 8 moves upward along the guiding rod 16 under the force and squeezes the spring 9. As the blocking block 8 rises, the top of the ventilation cavity 3 opens, and the gas inside the fermentation tank 1 is discharged outward through the air outlet holes 5 to achieve pressure relief. By rotating the adjusting rod 6, the pressing plate 7 is driven to move up and down, so as to adjust the pressure of the spring 9 on the blocking block 8, and further adjust the automatic pressure relief for gases with different pressures, meeting the usage needs of users.
[0026] As Figure 1 and Figure 2 shown, a stirring motor 10 is fixedly provided at the top of the fermentation tank 1, and a stirring rod 11 is arranged on the output shaft of the stirring motor 10;
[0027] By starting the stirring motor 10, the stirring rod 11 is driven to rotate, stirring the mulberry fruits inside the fermentation tank 1, thereby improving the stirring effect on the mulberry fruits.
[0028] As shown Figure 4 in the figure, a sealing gasket 12 is arranged at the top of the ventilation cavity 3 and is arranged in a conical shape, and is adapted to the specifications and dimensions of the plugging block 8;
[0029] By arranging the sealing gasket 12, the sealing effect between the plugging block 8 and the sealing gasket 12 is improved.
[0030] As shown Figure 4 and Figure 5 in the figure, mounting seats 13 are fixedly arranged at the top of the plugging block 8 and the bottom of the pressing plate 7, and both ends of the spring 9 are respectively arranged inside the two mounting seats 13;
[0031] Guide rods 16 are fixedly arranged at both ends inside the housing 4. Both ends of the plugging block 8 and the pressing plate 7 are slidably sleeved outside the guide rods 16. The bottom ends of the guide rods 16 are threadedly connected with limit rings 17;
[0032] By arranging the guide rods 16 and the limit rings 17, when the spring 9 needs to be replaced, first rotate the housing 4, remove the housing 4, and then rotate the two limit rings 17 in turn. After removing them from the outside of the guide rods 16, the plugging block 8 can be taken out, so that the spring 9 between the pressing plate 7 and the plugging block 8 can be taken out. After removing the old spring 9, put the top of the new spring 9 into the mounting seat 13 at the bottom of the pressing plate 7, and then sleeved the plugging block 8 outside the two guide rods 16, and at the same time make the bottom of the spring 9 located inside the mounting seat 13 at the top of the plugging block 8. Finally, screw the two limit rings 17 onto the outside of the guide rods 16, and the replacement of the spring 9 is completed. The operation is simple and convenient to use.
[0033] The working principle of an adjustable-pressure mulberry fruit fermentation device provided by the present utility model is as follows:
[0034] When in use, by opening the sealing cover 15, the mulberry fruit raw materials are poured into the fermentation tank 1 through the feeding pipeline 14. During the fermentation process of the mulberry fruit, by starting the stirring motor 10, the stirring rod 11 is driven to rotate, so as to stir the mulberry fruit;
[0035] When the pressure inside the fermentation tank 1 is too high, the gas inside the fermentation tank 1 enters the ventilation cavity 3, and pushes up the plugging block 8. The plugging block 8 moves upward along the guide rod 16 under the force, and compresses the spring 9. As the plugging block 8 rises, the top of the ventilation cavity 3 opens, and the gas inside the fermentation tank 1 is discharged outwards through the air outlet hole 5, realizing pressure relief.
[0036] The above has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and all these changes and improvements fall within the scope of the present utility model claimed.
