Description

Technical Field

[0001] The utility model relates to the technical field of wine fermentation tanks, in particular to a wine fermentation tank with a stirring function. Background Art

[0002] A wine fermentation tank is a container used for fermentation during the brewing process. It is usually made of materials such as stainless steel, ceramic or plastic, and is airtight and corrosion-resistant. The main function of a wine fermentation tank is to provide a suitable environment for yeast to convert sugar into alcohol and carbon dioxide. During the fermentation process, the wine fermentation tank needs to control the temperature, maintain an appropriate oxygen supply, and prevent the entry of external pollutants. Excessive stirring may disrupt the microbial community during the wine fermentation process and affect the fermentation effect and taste. A certain degree of stirring is required during the brewing process to ensure the uniformity and efficiency of the fermentation process, while minimizing interference with the microbial community. When the microorganisms attached to the inner wall of the tank participate in fermentation, the uneven stirring will lead to different degrees of acidification and fermentation, affecting the control of the wine body.

[0003] The patent with announcement number CN215906170U discloses a wine fermentation tank, and its technical highlights are: including a fermentation tank, an openable sealing cover is provided on the top of the fermentation tank, a rectangular filter frame with an opening on the top is provided at the bottom of the inner cavity of the fermentation tank, the side wall of the filter frame is abutted against the side wall of the inner cavity of the fermentation tank, connecting rods are symmetrically fixed at the four corners of the top of the rectangular filter frame, fixing strips are fixed between the two groups of connecting rods on the left and between the two groups of connecting rods on the right, and a feed hopper is provided on the top of the sealing cover. Although the above device solves the problem of collecting grain residues precipitated in the fermentation tank, there is still a problem of uneven stirring of the fermented material attached to the inner wall of the tank, which makes it easy to deteriorate.

[0009] Furthermore, a sealing ring is provided at the connection between the rotating rod and the circular opening.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0018] like Figures 1 to 4 As shown, a wine fermentation tank with a stirring function comprises a fermentation tank 1, a driving motor 3 connected to the top of the fermentation tank 1, an openable sealing cover 2 is provided on the top of the fermentation tank 1 and a discharge valve 4 is connected to the bottom of the fermentation tank 1, a stirring device is provided inside the fermentation tank 1, one end of the stirring device is passed through the middle position of the top of the fermentation tank 1 and is fixedly connected to the output end of the driving motor 3, and the other end is rotatably connected to the middle position of the bottom of the fermentation tank 1, the stirring device comprises a rotating rod 5 and a plurality of stirring blades 6, a circular opening 101 is provided in the middle position of the top of the fermentation tank 1, a rotating rod 5 is rotatably connected in the circular opening 101, the other end of the rotating rod 5 is rotatably connected to a limiting ring 102, the limiting ring 102 is fixedly connected to the middle position of the bottom of the fermentation tank 1, and the outer side of the rotating rod 5 is fixedly connected to the stirring blade 6.

[0019] like Figure 1 As shown, the wine fermentation tank with stirring function in the utility model is similar to the existing wine fermentation tank structure, such as the wine fermentation tank disclosed in the patent publication number CN215906170U. The main improvement of the utility model is that while stirring the wine body, the fermentation stability of the microorganisms in the tank is maintained. Figures 1 to 4 As shown, when a wine fermentation tank with a stirring function in the utility model is in use, the operator pours the fermented material from the sealing cover 2 into the fermentation tank 1, turns on the driving motor 3, and the driving motor 3 drives the stirring device to stir the fermented material in the tank. Here, a limit ring 102 is arranged in the middle of the bottom of the fermentation tank 1, and a bearing is arranged in the limit ring 102. The bearing makes the rotating rod 5 rotatably connected with the bottom of the fermentation tank 1, and the limit ring 102 fixes the rotating rod 5 in the middle position of the tank bottom; during the fermentation period, the operator can turn on the stirring device to stir the fermented material in the tank, and the rotating rod 5 drives the stirring blade 6 to rotate. After the fermentation of the wine body is completed, the wine is discharged from the discharge valve 4. Through the cooperation of the stirring device, the fermented material in the fermentation tank 1 is evenly fused, and the stirring blade 6 scrapes the microorganisms attached to the inner wall of the fermentation tank 1 to the bottom of the tank to prevent the accumulated microorganisms from fermenting at different degrees from the microorganisms in the tank, and the stirring blade 6 can prevent the microorganisms in the tank from being damaged during stirring.

[0020] like Figure 1 As shown, the plurality of stirring blades 6 are staggered and arranged with equal intervals.

[0021] Specifically, through this arrangement, the stirring blades 6 can evenly drive the fermented material to rotate in the fermentation tank 1, and the stirring blades 6 can drive the bottom of the fermentation tank 1 and the microorganisms in the tank to rotate together, preventing different temperatures in the tank caused by uneven fusion of the microorganisms, which affects the change of wine quality.

[0022] like Figure 1 As shown, one end of the stirring blade 6 is closely connected to the inside of the fermentation tank 1 .

[0023] Specifically, by setting the side walls of the stirring blades 6, the accumulated microorganisms on the inner wall of the fermentation tank 1 can be scraped off to the bottom of the tank, thereby improving the fermentation uniformity of the fermentation tank 1, and the width of multiple stirring blades 6 is equal to the length of the inner wall of the fermentation tank 1, thereby preventing the microorganisms attached to the inner wall of the fermentation tank 1 from remaining.

[0024] like Figure 1 As shown, circular holes 601 are provided on both sides of the stirring blade 6 connected to the upper half of the rotating rod 5 .

[0025] Specifically, by configuring the stirring blades 6 on the upper portion of the rotating rod 5 in this way, when stirring the microorganisms in the fermentation, the microorganisms can pass through the circular hole 601, thereby preventing the imbalance of the microorganisms caused by excessive stirring, and the stirring blades 6 on the lower portion of the rotating rod 5 drive the fermentation at the bottom of the tank to roll in the tank, so that the fermentation can be fully integrated.

[0026] like Figure 1 As shown, a sealing ring 7 is provided at the connection between the rotating rod 5 and the circular opening 101 .

[0027] Specifically, this arrangement prevents the fermented material from overflowing from the connection between the rotating rod 5 and the circular opening 101 to the outside of the fermentation tank 1 during fermentation, and also prevents oxygen from entering the fermentation tank 1 from the circular opening 101 to affect the anaerobic fermentation in the tank.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
