Abstract
Description
Technical Field
[0001] This invention relates to the field of baijiu brewing technology, specifically to a baijiu temperature-controlled fermentation device. Background Technology
[0002] The brewing process of baijiu (Chinese liquor) involves fermentation technology, through which microorganisms transform raw materials into alcohol and other flavor compounds. Temperature is a crucial factor affecting fermentation, therefore it needs to be controlled to ensure the smooth progress of the process.
[0003] Existing temperature-controlled fermentation equipment for baijiu only uses a stirring mechanism to stir the grain in the fermentation tank. However, the grain accumulates in the fermentation tank, and its weight increases after absorbing water. This makes it easy for the stirring mechanism to be damaged due to excessive resistance during the stirring process, or for the stirring mechanism to fail to move the grain at the bottom of the fermentation tank. Therefore, baijiu brewing companies reduce the amount of grain in the fermentation tank to ensure the fermentation effect of baijiu in the fermentation tank, which will lead to a decrease in the efficiency of baijiu brewing. Summary of the Invention
[0004] To address the shortcomings of existing technologies, this invention provides a temperature-controlled fermentation device for baijiu (Chinese liquor), which solves the problem that existing temperature-controlled fermentation devices for baijiu have poor stirring effects on the grains in the fermentation tank, leading to a reduction in the amount of grains in the fermentation tank to ensure the fermentation effect of baijiu, thereby reducing the fermentation efficiency of baijiu.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a temperature-controlled fermentation device for baijiu (Chinese liquor), comprising a fermentation tank, a liquid outlet pipe, a servo motor, a temperature sensor, and a circulating water tank. The fermentation tank has a feed inlet at its top, and the liquid outlet pipe is located on the side wall of the fermentation tank. The servo motor is fixedly connected to the top of the fermentation tank, and a drive rod is fixedly connected to the drive end of the servo motor. A U-shaped rod is fixedly connected to the bottom end of the drive rod, and a stirring rod is fixedly connected to the bottom of the U-shaped rod. Multiple stirring blades are fixedly connected at equal intervals to both sides of the stirring rod. A water outlet plate is provided on the inner bottom wall of the fermentation tank, and multiple water outlet pipes are fixedly connected to the outer surface of the water outlet plate. The temperature sensor is fixedly connected to the inner wall of the fermentation tank, and the circulating water tank is fixedly connected to the other side of the fermentation tank. The circulating water tank has a water injection pipe fixedly connected to the side wall away from the fermentation tank, and a water suction pipe fixedly connected to the side wall of the circulating water tank near the fermentation tank. The water suction pipe passes through the side wall of the fermentation tank and extends into the interior of the fermentation tank. A connecting pipe is fixedly connected to the bottom of the circulating water tank. The end of the connecting pipe away from the circulating water tank passes through the bottom of the fermentation tank and extends into the interior of the fermentation tank. The end of the connecting pipe away from the circulating water tank is rotatably connected to the water outlet plate. A movable sleeve is movably fitted on the outer surface of the vertical rod of the U-shaped rod. A connecting rod is fixedly connected to the outer surface of the movable sleeve. A limit rod is fixedly connected to the inner top wall of the fermentation tank. A dispersing mesh plate is rotatably connected to the bottom end of the limit rod. A connecting shaft is fixedly connected to the top of the dispersing mesh plate. The top end of the connecting shaft is rotatably connected to the connecting rod.
[0006] Preferably, the bottom end of the stirring rod is fixedly connected to the top of the water outlet plate.
[0007] Preferably, all of the multiple water outlet pipes are curved pipes, and the multiple water outlet pipes are arranged in a ring array with the central axis of the water outlet plate as the center.
[0008] Preferably, the bottom of the dispersing mesh is immersed in the wine liquid in the fermentation tank.
[0009] Preferably, the feed inlet is located on one side of the servo motor.
[0010] Preferably, the connecting shaft is fixedly connected to the top center position of the dispersing mesh plate.
[0011] Working Principle: During use, the grain to be fermented is placed into the fermentation tank through the feed inlet. The fermentation effect can also be observed through the feed inlet. When stirring is needed, liquid from the fermentation tank is drawn into the circulating water tank via the suction pipe. The liquid is then injected into the outlet plate via the connecting pipe on the circulating water tank. The curved outlet pipe continuously injects hot water into the fermentation tank, causing the grain at the bottom of the tank to move. As the liquid moves the grain, a servo motor drives the stirring blades on the stirring rod to rotate in the direction of the liquid flow, further accelerating the liquid flow and reducing the fermentation time. The load on the connection between the grain and the stirring blade in the fermentation tank is beneficial for increasing the amount of grain fermenting in the tank through stirring. At this time, the drive rod will move the movable sleeve on the U-shaped rod, causing the connecting rod on the movable sleeve to move. The connecting rod drives the dispersing screen to rotate around the limiting rod through the connecting shaft, causing the dispersing screen connected to the limiting rod to swing back and forth. The dispersing screen comes into contact with the liquid surface in the fermentation tank, causing the dispersing screen to beat the liquid surface and disperse the esters on the liquid surface, thus making the esters more readily incorporated into the liquid. Hot water from the fermentation tank can be injected into other fermentation tanks through the water injection pipe to reduce the heat required to heat the liquid in the fermentation tank, thereby reducing the cost of baijiu fermentation.
[0012] This invention provides a temperature-controlled fermentation device for baijiu (Chinese liquor). It has the following beneficial effects:
[0013] 1. This temperature-controlled fermentation device for baijiu (Chinese liquor) can draw liquid from the fermentation tank into the circulating water tank through the suction pipe on the circulating water tank, and inject the liquid from the circulating water tank into the water outlet plate through the connecting pipe on the circulating water tank. The water outlet pipe on the water outlet plate is a curved pipe, which allows the continuous injection of hot water into the fermentation tank through the water outlet pipe to move the grain at the bottom of the fermentation tank.
[0014] 2. This temperature-controlled fermentation device for baijiu uses a servo motor to drive the stirring blades on the stirring rod to rotate in the direction of the liquid flow in the fermentation tank. This allows the stirring blades to further accelerate the liquid flow in the fermentation tank, thereby reducing the load on the connection between the stirring blades and the stirring rod from the grains in the fermentation tank. This improves the stirring effect of the grains in the fermentation tank and increases the amount of grains fermenting in the tank.
[0015] 3. This temperature-controlled fermentation device for baijiu can inject hot water from the fermentation tank into other fermentation tanks through a water injection pipe, thereby reducing the heat required to heat the liquid in the fermentation tank and thus reducing the cost of baijiu fermentation.
[0016] 4. This temperature-controlled fermentation device for baijiu uses a drive rod to move the movable sleeve on the U-shaped rod, causing the dispersing mesh plate connected to the limit rod to swing back and forth. The dispersing mesh plate comes into contact with the surface of the liquor in the fermentation tank, causing the dispersing mesh plate to pat the surface of the liquor, thus breaking up the esters on the surface of the liquor and making the esters more readily integrated into the liquor.

Example
[0022] like Figure 1-3As shown, this embodiment of the invention provides a temperature-controlled fermentation device for baijiu (Chinese liquor), including a fermentation tank 1, a liquid outlet pipe 3, a servo motor 4, a temperature sensor 11, and a circulating water tank 12. The fermentation tank 1 has a feed inlet 2 at its top, and the liquid outlet pipe 3 is located on the side wall of the fermentation tank 1. The servo motor 4 is fixedly connected to the top of the fermentation tank 1, and a drive rod 5 is fixedly connected to the drive end of the servo motor 4. A U-shaped rod 6 is fixedly connected to the bottom end of the drive rod 5, and a stirring rod 7 is fixedly connected to the bottom of the U-shaped rod 6. Multiple stirring blades 8 are fixedly connected at equal intervals to both sides of the stirring rod 7. A water outlet plate 9 is provided on the inner bottom wall of the fermentation tank 1, and multiple water outlet pipes 10 are fixedly connected to the outer surface of the water outlet plate 9. The temperature sensor 11 is fixedly connected to the inner wall of the fermentation tank 1, and the circulating water tank 12 is fixedly connected to the other side wall of the fermentation tank 1, with the circulating water tank 12 located away from the fermentation tank 1. A water injection pipe 13 is fixedly connected to the side wall. A water suction pipe 14 is fixedly connected to the side wall of the circulating water tank 12 near the fermentation tank 1. The water suction pipe 14 passes through the side wall of the fermentation tank 1 and extends into the interior of the fermentation tank 1. A connecting pipe 15 is fixedly connected to the bottom of the circulating water tank 12. One end of the connecting pipe 15 away from the circulating water tank 12 passes through the bottom of the fermentation tank 1 and extends into the interior of the fermentation tank 1. The other end of the connecting pipe 15 away from the circulating water tank 12 is rotatably connected to the water outlet plate 9. A movable sleeve 16 is movably sleeved on the outer surface of the vertical rod of the U-shaped rod 6. A connecting rod 17 is fixedly connected to the outer surface of the movable sleeve 16. A limiting rod 18 is fixedly connected to the inner top wall of the fermentation tank 1. A dispersing mesh plate 19 is rotatably connected to the bottom end of the limiting rod 18. A connecting shaft 20 is fixedly connected to the top of the dispersing mesh plate 19. The top end of the connecting shaft 20 is rotatably connected to the connecting rod 17.
[0023] The bottom end of the stirring rod 7 is fixedly connected to the top of the water outlet plate 9, allowing the servo motor 4 to drive the stirring rod 7 to rotate the water outlet plate 9. This allows adjustment of the direction of the water outlet pipe 10 on the water outlet plate 9, ensuring that the hot water injected into the fermentation tank 1 through the water outlet pipe 10 moves the grain in the fermentation tank 1. Multiple water outlet pipes 10 are curved pipes, arranged in a circular array around the central axis of the water outlet plate 9. Because the multiple water outlet pipes 10 in the circular array are curved, the continuous injection of hot water into the fermentation tank 1 through the water outlet pipes 10 can move the grain at the bottom of the fermentation tank 1. The bottom of the dispersing mesh plate 19 is immersed in the water outlet plate 9. In the wine in fermentation tank 1, the dispersing mesh plate 19 is designed to contact the surface of the wine in fermentation tank 1, allowing the dispersing mesh plate 19 to tap the surface of the wine, thus breaking up the esters on the surface of the wine and making the esters more readily absorbed into the wine. The feed inlet 2 is located on one side of the servo motor 4. Through the feed inlet 2, grains to be fermented can be put into fermentation tank 1, and the fermentation effect of the grains in fermentation tank 1 can also be observed from the feed inlet 2. The connecting shaft 20 is fixedly connected to the top center of the dispersing mesh plate 19, so that the dispersing mesh plate 19 can be driven to swing back and forth around the limiting rod 18 through the connecting shaft 20 via the connecting rod 17.
