[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figures 1 to 4 As shown, the utility model provides a fermentation stirring device for fermented black beans, comprising a fermentation tank 1, and a tank cover 2 detachably arranged at the upper end of the fermentation tank 1 and capable of achieving sealing, a plurality of circular stirring plates 9 are stacked at the bottom of the inner cavity of the fermentation tank 1, the stirring plates 9 are preferably made of medical grade plastic and will not produce toxins even if soaked for a long time, a silicone ring 10 is glued and fixed around the stirring plate 9, and the silicone ring 10 is bent downward (such as Figure 4 As shown), the curved setting can avoid damage to the fermented black beans, and the transition is smoother. A circular through hole 12 for the pull rope 4 to pass through is provided in the middle of several stirring plates 9 and the middle of the tank cover 2. The diameter of the through hole 12 is smaller than the diameter of the silicone ball 8, and the range is 2 to 4MM. Because the silicone ball 8 is flexible, the stirring plate 9 can be limited under normal conditions. If the pull rope 4 is pulled hard, the silicone ball 8 can pass through the through hole 12 in the middle of the stirring plate 9.

[0025] The silicone ring 10 and the silicone ball 8 are both made of medical grade silicone, wherein the distance between every two silicone balls 8 should be greater than 2 mm of the thickness of the stirring plate 9 , thereby achieving better positioning of the stirring plate 9 .

[0026] The length of the pull rope 4 between the two stirring plates 9 is the same as the distance between the bottom of the inner cavity of the fermenter 1 and the lower end of the tank cover 2, so that when the stirring plate 9 moves from the bottom of the inner cavity of the fermenter 1 to fit the lower end of the tank cover 2, stirring can be achieved once. The number of stirring plates 9 set is equal to the number of stirring times, so the user can make specific settings as needed. A number of silicone balls 8 for limiting the stirring plates 9 are fixed on the surface of the pull rope 4.

[0027] A winding mechanism 3 for winding the draw cord 4 is provided on one side of the upper end of the tank cover 2. The winding mechanism 3 includes a bracket 31 fixed to one side of the upper end of the tank cover 2 by screws. The structure of the bracket 31 is as follows: Figure 1 As shown, a turning handle 32 is penetrated and rotatably provided at the inclined portion of the upper end of the bracket 31, and the connection between the turning handle 32 and the bracket 31 is rotatably provided through a bearing. This installation method is a prior art and will not be described in detail. A winding drum 33 is fixedly provided at the lower end of the turning handle 32, and the winding part of the winding drum 33 is fixed to one end of the pull rope 4, so that the pull rope 4 and the silicone ball 8 can be wound on the winding drum 33.

[0028] Specifically, when several stirring plates 9 are stacked, the pull rope 4 is coiled between two stirring plates 9, and a bottom plate 11 is fixed to one end of the pull rope 4 located at the bottom of the inner cavity of the fermenter 1. The bottom plate 11 is set to medical grade plastic, and the diameter of the bottom plate 11 is much larger than the diameter of the through hole 12. The bottom plate 11 fits against the stirring plate 9 to achieve positioning.

[0029] A circular collecting tray 6 is fixed in the middle of the upper end of the can cover 2, and an opening corresponding to and connected to the through hole 12 in the middle of the can cover 2 is opened in the middle of the collecting tray 6, and the diameter of the opening is larger than the diameter of the through hole 12. A slot 7 is opened on one side of the collecting tray 6, and a baffle 5 is detachably inserted in the slot 7. The collecting tray 6 is used to collect the fermented black beans dripping from the surface of the silica gel ball 8, thereby realizing the collection function, and the slot 7 is provided to facilitate the cleaning of the collecting tray 6.

[0030] It should be noted that the through hole 12 at the upper end of the tank cover 2 is always blocked by the silicone ball 8 to achieve sealing, thereby preventing air from entering the fermentation tank 1 and making the fermentation tank 1 have a better sealing effect.

[0031] Under normal conditions, the silicone ball 8 at the uppermost end of the pull rope 4 is located in the opening in the middle of the collecting tray 6 and abuts against the through hole 12 in the middle of the tank cover 2 .

[0032] Principle and process of this utility model:

[0033] The staff stacks a plurality of stirring plates 9 at the bottom of the fermentation tank 1 in advance, then puts the fermented black beans into the fermentation tank 1, and seals the tank cover 2 and the fermentation tank 1 to achieve fermentation.

[0034] When stirring is required, the user only needs to turn the handle 32, which drives the winding disk 33 to rotate and then causes the pull rope 4 to be wound and collected on the winding disk 33. At this time, the silicone ball 8 on the surface of the pull rope 4 is deformed by force and continues to pass through the through hole 12 on the tank cover 2. At this time, the stirring disk 9 gradually moves from the bottom of the inner cavity of the fermentation tank 1 to the upper part and fits with the tank cover 2 under the pulling of the pull rope 4 and the limitation of the silicone ball 8. During the movement of the stirring disk 9, the fermented black beans at the bottom of the fermentation tank 1 will be turned to the upper part, thereby achieving the stirring effect;

[0035] At this time, the user continues to rotate the handle 32 with force, and the silicone ball 8 on the surface of the pull rope 4 will deform and move out from the through hole 12 of the stirring plate 9 until the stirring plate 9 falls on the next silicone ball 8 and is fixed, thereby realizing the next stirring action in this cycle.

[0036] In summary, the device can fully stir the fermented black beans in the fermentation tank 1 while preventing the fermented black beans from being damaged by force.
