Technical Field
[0001] The utility model relates to a fermentation tank, in particular to a fermentation tank with a pressing plate. Background Art
[0002] Food fermentation generally refers to fermenting raw materials with salt solution, allowing it to penetrate into the food tissue to increase its osmotic pressure and reduce its moisture content to prevent food spoilage or improve the quality and taste of food. During fermentation, the food to be fermented is first placed in a container. In order to prevent the food from floating on the surface of the liquid and causing the floating part to deteriorate, a heavy object such as a stone is placed on it to suppress it. Finally, a layer of plastic film is covered on the container or a simple lid is placed on it for simple sealing and dust prevention.
[0003] In food fermentation factories with large production volumes, large-capacity, open-top plastic barrels or cans are generally used, and a large weight is needed to press the food to solve the floating problem.

When the limit plate 44 is used to limit the pressure rod 4, there are requirements for the length of the limit plate 44 along the direction of the pressure rod 4 and the length of the pressure rod 4. Specifically, the length of the pressure rod 4 should be less than the distance from the end of the limit plate 44 away from the side wall of the tank body 1 to the end of the second U-shaped fixing part 42 close to the side wall of the tank body 1. At the same time, the length of the pressure rod 4 should also be greater than the distance from the end of the limit plate 44 away from the side wall of the tank body 1 to the end of the second U-shaped fixing part 42 away from the side wall of the tank body 1. Only in this way can the pressure rod 4 achieve its own detachability and the fixing effect on the pressure plate 3.
[0036] When using this embodiment, it can be used according to different food fermentation process requirements. One way is to put a certain amount of food into the fermentation tank according to the requirements, put in the pressing plate 3, put the two ends of the pressing rod 4 into the pressing rod fixing piece and fix it, so that the pressing rod 4 fixes the position of the pressing plate 3, and finally add the fermentation liquid and immerse the pressing plate 3 partially or completely in the fermentation liquid, cover the tank cover 2, and tighten the quick-opening bolt 6 to seal the fermentation tank; another way of using it can be: put the food and fermentation liquid into the fermentation tank according to a certain amount, put in the pressing plate 3, put the two ends of the pressing rod 4 into the pressing rod fixing piece and fix it, so that the pressing rod 4 fixes the position of the pressing plate 3, cover the tank cover 2, and tighten the quick-opening bolt 6. When the fermentation tank needs to be moved, it can be moved by the upper ear 71 and the lower ear 72 on the outside of the tank body 1 cooperating with each other.
