Description

Technical Field

[0001] The invention relates to the technical field of microbial brewing, in particular to a built-in stirrer for microbial brewing equipment. Background Art

[0002] A brewing jar is a device used for brewing wine, a process that uses microbial fermentation to produce alcoholic beverages with a certain concentration. Both raw materials and containers are essential for brewing grain-based wine. Archaeological discoveries of brewing utensils dating back over 5,000 years indicate that brewing existed during the legendary Yellow Emperor and Xia Yu eras, but that its origins predate these times.

[0003] There are still the following disadvantages in actual use of brewing tanks:

[0004] 1. Existing winemaking tanks need to be stirred during the winemaking process to accelerate microbial fermentation and fully ferment, so as to improve the quality of the wine. However, the existing technology usually involves opening the top cover of the equipment for manual stirring, which is inefficient, time-consuming and labor-intensive, and reduces the efficiency of winemaking. 2. Opening the top cover for manual stirring may allow some external microorganisms to enter the winemaking box, resulting in winemaking failure or reduced wine quality. 3. Stirring requires turning the raw materials at the bottom to the surface. Manual stirring is not easy to fully stir the raw materials in the winemaking tank, resulting in insufficient stirring.

[0005] Therefore, in view of the above situation, there is an urgent need to develop a built-in agitator for microbial brewing equipment to overcome the shortcomings in current practical applications. Summary of the Invention

[0006] The purpose of the present invention is to provide a built-in agitator for microbial brewing equipment to solve the problems raised in the above background technology.

[0007] To solve the above technical problems, the present invention is achieved through the following technical solutions:

[0008] The present invention is a built-in agitator for microbial brewing equipment, comprising a brewing tank, a stirring mechanism, and a constant temperature mechanism. The stirring mechanism is located in the brewing tank and is distributed in a circular array around its axis.

[0009] The stirring mechanism includes a servo motor, the output shaft of the servo motor is fixedly connected to the main drive shaft, a plurality of axial support rods are fixedly connected to the outer wall of the main drive shaft, a vertical spiral is fixedly connected to the outer wall of the main drive shaft, a middle spiral and a peripheral spiral are arranged on the outside of the main drive shaft, the outer wall of each of the axial support rods is fixedly connected to four fixed brackets, the fixed brackets are fixedly connected to the lower surfaces of the middle spiral and the peripheral spiral, a vortex stirring paddle is fixedly installed on the upper surface of the two peripheral spirals, the outer wall of the lowest axial support rod is fixedly connected to an axial stirring blade, longitudinal spoiler holes are opened on the outer walls of the two middle spirals, a scraper is fixedly connected to the outer wall of the main drive shaft, and the outer wall of each scraper is opened with axial spoiler holes, a filter is fixedly installed on the inner wall of the brewing tank, and a flow control component is provided below the filter.

[0010] Furthermore, the outer wall of the brewing tank is respectively provided with a feed port, a discharge port and a liquid outlet, and a high-pressure exhaust port, an equipment control panel and a motor cover are provided on the top of the brewing tank, and the feed port and the liquid outlet are respectively located on opposite sides of the brewing tank.

[0011] The above-mentioned technical solution plays an auxiliary role in the fermentation of raw materials. In order to ensure the stability of microorganisms, the interior of the brewing tank is a closed environment. Carbon dioxide and other gases will be produced during the fermentation and stirring process. In a closed environment, the internal air pressure is too high and an explosion will occur. The high-pressure exhaust port set on the top of the tank solves this problem, so that the air pressure inside the tank is always balanced with that outside the tank.

[0012] Furthermore, there are two central spiral members and two peripheral spiral members, and they are distributed in a circular array with the main drive shaft as the axis. The two central spiral members are staggered by 180 degrees, and the two peripheral spiral members are staggered by 180 degrees.

[0013] By adopting the above technical solution, the raw materials in the tank can be fully stirred. The vertical spiral, the middle spiral and the outer spiral rotate synchronously. The axial support rod plays a supporting role and can also mix the axial raw materials during the rotation process. Axial flow and radial flow can be generated simultaneously during the stirring process. The raw materials at the bottom can be turned to the surface during stirring. The vortex stirring paddle is conical, which produces a certain extrusion pressure on the raw materials during stirring, and also generates vortex, making the stirring more sufficient and efficient.

[0014] Furthermore, the scraper is fixedly connected to the lowest axial support rod, and the filter is located below the scraper and overlapped therewith.

[0015] The above technical solution can clear silt and block the filter. When the flow control element descends, the filter will filter the liquid to achieve solid-liquid separation. During filtration, the pores of the filter are easily blocked by the raw materials. At this time, the rotating scraper continuously scrapes the filter to ensure that it can filter out the liquid smoothly.

[0016] Furthermore, a threaded block is provided on the outer wall of one end of the main driving shaft away from the servo motor, the inner wall of the flow control part is threadedly connected to the threaded block, the outer wall of the flow control part is slidingly connected to the inner wall of the brewing tank, the discharge port is located above the filter screen, and the liquid outlet is located below the filter screen.

[0017] By adopting the above technical solution, the threaded block controls the flow control part. After fermentation is complete, the servo motor is started to rotate in the opposite direction. The rotation of the threaded block drives the flow control part to descend to the bottom of the brewing tank.

[0018] Furthermore, the constant temperature mechanism is located on the outer ring of the winemaking tank barrel wall, and the constant temperature mechanism includes a constant temperature controller and a constant temperature jacket.

[0019] The above technical solution can maintain a constant temperature in the tank. When the temperature of microbial wine fermentation is higher than 30℃, it is easy to produce acid and even yeast death. When the temperature is lower than 20℃, the raw material is difficult to ferment. Therefore, a constant temperature tool is needed to keep the temperature in the tank between 25-30℃.

[0020] The present invention has the following beneficial effects:

[0021] (1) In the present invention, the vertical spiral, the middle spiral and the outer spiral rotate synchronously. According to the basic laws of fluid mechanics, they can achieve a better mixing effect and cause less damage to the raw materials. The axial support rod plays a supporting role and can also mix the axial raw materials during the rotation process. Therefore, the stirring mechanism can simultaneously generate axial flow and radial flow during the stirring process, and can turn the raw materials at the bottom to the surface during stirring. The vortex stirring paddle is conical, which produces a certain extrusion force on the raw materials during stirring, and also generates vortex, making the stirring more sufficient and efficient.

[0022] (2) After fermentation is complete, start the servo motor to rotate in the opposite direction. The vertical spiral and the outer spiral rotate in the opposite direction to squeeze the raw materials downward, which can better filter out the liquid. The rotation of the screw block drives the flow control part to drop to the bottom of the brewing tank. During fermentation, the flow control part is close to the filter screen, and the liquid will not flow out through the filter screen. When the flow control part drops, the filter screen will filter the liquid to achieve solid-liquid separation. During filtration, the pores of the filter screen are easily blocked by the raw materials. At this time, the rotating scraper continues to scrape the filter screen to ensure that it can filter out the liquid smoothly.

[0023] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] See also Figures 1-9 As shown, the present invention is a built-in agitator for microbial brewing equipment, comprising a brewing tank 1, a stirring mechanism 2, and a constant temperature mechanism 3. The stirring mechanism 2 is located in the brewing tank 1 and is distributed in a circular array around its axis.

[0038] The stirring mechanism 2 includes a servo motor 201, the output shaft of the servo motor 201 is fixedly connected to the main drive shaft 202, a plurality of axial support rods 2021 are fixedly connected to the outer wall of the main drive shaft 202, a vertical spiral 2022 is fixedly connected to the outer wall of the main drive shaft 202, a middle spiral 2023 and a peripheral spiral 2024 are arranged on the outside of the main drive shaft 202, and the outer wall of each axial support rod 2021 is fixedly connected to four fixed brackets 2025, the fixed brackets 2025 are fixedly connected to the lower surfaces of the middle spiral 2023 and the peripheral spiral 2024, and a vortex stirring paddle 2026 is fixedly installed on the upper surface of the two peripheral spirals 2024. The wall is fixedly connected with an axial stirring blade, the outer walls of the two middle spirals 2023 are provided with longitudinal spoiler holes 2027, the outer wall of the main drive shaft 202 is fixedly connected with a scraper 203, the outer wall of each scraper 203 is provided with an axial spoiler hole 2031, and a filter 107 is fixedly installed on the inner wall of the brewing tank 1, and a flow control part 108 is provided below the filter 107. Start the servo motor 201, and the main drive shaft 202 drives the vertical spiral 2022, the middle spiral 2023 and the outer spiral 2024 to rotate synchronously to generate radial flow. The axial support rod 2021 plays a supporting role. While it can also mix the axial raw materials during the rotation process, the axial stirring blade at the bottom assists in mixing the raw materials at the bottom.

[0039] The outer wall of the brewing tank 1 is respectively provided with a feed port 101, a discharge port 102 and a liquid outlet 103. A high-pressure exhaust port 104, an equipment control panel 105 and a motor cover 106 are provided on the top of the brewing tank 1. The discharge port 102 and the liquid outlet 103 are respectively located on opposite sides of the brewing tank 1. In order to ensure the stability of microorganisms, the interior of the brewing tank 1 is a closed environment. Carbon dioxide and other gases will be produced during the fermentation and stirring process. In a closed environment, the internal air pressure is too high and an explosion will occur. The high-pressure exhaust port 104 arranged on the top of the tank solves this problem, so that the air pressure inside the tank is always balanced with that outside the tank.

[0040] There are two middle spirals 2023 and two outer spirals 2024, and they are distributed in a circular array with the main drive shaft 202 as the axis. The two middle spirals 2023 are staggered at 180°, and the two outer spirals 2024 are staggered at 180°. The staggered distribution of the two middle spirals 2023 can make the axial blades form a closed loop, and the raw materials on the same plane are radially mixed during rotation. The same is true for the outer spirals 2024. The axial support rod 2021 mixes the axial raw materials during rotation, and generates axial flow and radial flow at the same time during the stirring process, making the stirring more sufficient and efficient.

[0041] The scraper 203 is fixedly connected to the lowest axial support rod 2021. The filter screen 107 is located below the scraper 203 and overlaps with it. When the flow control member 108 is lowered, the filter screen 107 will filter the liquid to achieve solid-liquid separation. During filtration, the pores of the filter screen 107 are easily blocked by the raw materials. At this time, the rotating scraper 203 continuously scrapes the filter screen 107 to ensure that it can filter out the liquid smoothly. The setting of the axial flow disturbance hole 2031 can mix the raw materials around the scraper 203, such as Figure 2-3 shown.

[0042] A threaded block 2028 is provided on the outer wall of one end of the main driving shaft 202 away from the servo motor 201, and the inner wall of the flow control part 108 is threadedly connected to the threaded block 2028. The outer wall of the flow control part 108 is slidingly connected to the inner wall of the brewing tank 1. The discharge port 102 is located above the filter screen 107, and the liquid outlet 103 is located below the filter screen 107. After the fermentation is complete, the servo motor 201 is started to rotate in the opposite direction, and the threaded block 2028 rotates to drive the flow control part 108 to descend to the bottom of the brewing tank 1.

[0043] The constant temperature mechanism 3 is located on the outer ring of the barrel wall of the brewing tank 1. The constant temperature mechanism 3 includes a constant temperature controller 301 and a constant temperature jacket 302. When the temperature of microbial brewing fermentation is higher than 30°C, it is easy to produce acid or even die yeast. When the temperature is lower than 20°C, the raw material is difficult to ferment. Therefore, a constant temperature tool is needed to keep the temperature in the tank between 25-30°C.

[0044] The working principle and use process of the present invention:

[0045] The constant temperature mechanism 3 ensures that the temperature in the brewing tank 1 is kept at a constant temperature. Microbial brewing fermentation takes 7-14 days. During this period, multiple stirrings are required to fully mix the raw materials. When stirring is required, the servo motor 201 is started, and its output shaft drives the main drive shaft 202 to rotate clockwise. The main drive shaft 202 drives the vertical spiral 2022, the middle spiral 2023 and the outer spiral 2024 to rotate synchronously. This design has a good mixing effect and causes less damage to the raw materials. The axial support rod 2021 plays a supporting role. During the rotation process, the axial raw materials can also be mixed. Therefore, the stirring mechanism 2 can generate axial flow and radial flow at the same time during the stirring process. The raw materials at the bottom can be turned to the surface during stirring. The vortex stirring paddle 2026 is conical, which produces a certain extrusion force on the raw materials during stirring, and also produces The vortex makes the stirring more sufficient and efficient. After the fermentation is complete, the servo motor 201 is started to rotate in the opposite direction. The vertical spiral 2022 and the peripheral spiral 2024 rotate in the opposite direction to squeeze the raw materials downward, which can better filter out the liquid. The screw block 2028 rotates to drive the flow control part 108 to descend to the bottom of the brewing tank 1. During fermentation, the flow control part 108 is close to the filter screen 107, and the liquid will not flow out through the filter screen 107. When the flow control part 108 descends, the filter screen 107 will filter the liquid to achieve solid-liquid separation. During filtration, the pores of the filter screen 107 are easily blocked by the raw materials. At this time, the rotating scraper 203 continues to scrape the filter screen 107 to ensure that it can filter out the liquid smoothly. The liquid outlet 103 is opened to collect the liquid. After collection, the discharge port 102 can be opened to discharge the raw materials in the tank and clean the tank to prepare for the next fermentation.
