DETAILED DESCRIPTION

[0032] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0033] like Figure 1-4 As shown, an anaerobic aerobic beverage fermentation device includes a fermentation tank 1, a sealing chamber 9 is installed on the upper surface of the fermentation tank 1, a heating wire 3 and a water pipe 4 are installed in the tank body of the fermentation tank 1, and the water pipe 4 is arranged in a spiral shape;

[0034] A driving assembly is installed inside the sealing chamber 9, and the driving assembly is installed on the upper surface of the fermentation tank 1. The driving assembly is in transmission connection with the upper end of the stirring assembly 13, and the lower end of the stirring assembly 13 is installed inside the fermentation tank 1.

[0035] The upper end of the stirring assembly 13 is connected to one end of the gas-liquid inlet pipe 16, and the other end of the gas-liquid inlet pipe 16 passes through the sealing chamber 9 and is respectively connected to the gas supply assembly and the liquid supply assembly through the three-way valve 17; the outer wall of the gas-liquid inlet pipe is sealed with the sealing chamber to ensure the sealing performance when the gas-liquid inlet pipe is connected to the stirring assembly, to avoid leakage when the gas-liquid inlet pipe passes gas or liquid into the fermenter through the stirring assembly, and to avoid the internal space of the fermenter from contacting with the outside world to affect the fermentation of substances inside the fermenter;

[0036] An appropriate amount of clean air is introduced into the fermentation tank through the gas-liquid inlet pipe to meet the aerobic fermentation requirements of the substances inside the fermentation tank, so that the substances inside the fermentation tank can be converted into aerobic fermentation or anaerobic fermentation.

[0037] Specifically, a feed port 8 is provided on the upper side wall of the fermentation tank 1, a drain port 2 is provided on the lower side wall of the fermentation tank 1, and a slag discharge port 23 is provided at the bottom of the fermentation tank 1. The feed port can fill raw materials into the fermentation tube, the drain port can discharge the beverage that has been fermented and preliminarily filtered to the outside for collection, and the slag discharge port can discharge the residue formed after fermentation to the outside, which is convenient for subsequent cleaning of the interior of the fermentation tank and greatly reduces the cleaning pressure; further, sealing valves are installed at the feed port, the drain port and the slag discharge port to ensure the sealing requirements during the fermentation process of the fermentation tank.

[0038] Specifically, the tank body of the fermentation tank 1 is divided into an outer shell and an inner tank, the heating wire 3 and the water pipe 4 are spirally wound between the outer shell and the inner tank, and the heating wire 3 and the water pipe 4 are arranged at an upper and lower interval;

[0039] The space between the outer shell and the inner liner is in a vacuum state or filled with heat-insulating material;

[0040] The fermentation tank adopts a double-layer structure and achieves the insulation requirement by evacuating the interlayer and filling it with insulation materials to prevent the external environment from affecting the substances in the fermentation tank. The operator can heat or cool the substances in the fermentation tank by passing hot water or cold water into the water pipe as needed;

[0041] When it is necessary to heat the material inside the fermentation tank, the heating wire cooperates with the water pipe passing hot water to achieve heating and insulation of the material inside the fermentation tank; when working, the heating wire is made of copper wire, which has a small specific heat capacity and can quickly heat the material inside the fermentation tank. The hot water in the water pipe has a large specific heat capacity and can continuously keep the material inside the fermentation tank warm. The hot water passed through the water pipe in conjunction with the heating wire can effectively reduce power consumption, further reduce fermentation costs, and speed up the fermentation reaction rate.

[0042] Specifically, the driving assembly includes a motor 10, and the working end of the motor 10 is connected to the stirring assembly 13 through a gear set 11 or a belt transmission assembly. The driving assembly drives the stirring assembly to rotate so as to evenly mix and contact the substrate, microorganisms and culture medium, thereby providing more substrates for the microorganisms to participate in the reaction, and allowing the microorganisms to quickly assimilate the substrates, so as to speed up the reaction and improve the efficiency of fermentation; in addition, during the stirring process, more oxygen and nutrients can be provided to the microorganisms, thereby increasing the nutrient content of the fermentation and improving the quality and yield of the beverage;

[0043] Furthermore, during the stirring process, the microorganisms and culture medium can form a suspension, which prevents the accumulation and agglomeration of waste at the bottom, avoids the formation of fermentation being destroyed, and wastes substrate and microbial resources. At the same time, stirring can also promote the contact between oxygen and microorganisms, prevent oxygen from accumulating at the bottom, and reduce the generation of bubbles.

[0044] Furthermore, stirring can maintain a uniform temperature distribution in the fermentation environment, promote the mixing and contact of substrates, microorganisms and culture medium, increase the population density of microorganisms, stabilize enzyme activity, and reduce the presence of foreign matter;

[0045] The stirring assembly 13 includes a stirring shaft 1301 and a stirring rod 1302. The stirring shaft 1301 and the stirring rod 1302 are both hollow. The stirring shaft 1301 is connected to the stirring rod 1302. The stirring rod 1302 is provided with a through hole, which can facilitate the gas or liquid to be introduced into the gas-liquid inlet pipe and evenly distributed to the inside of the fermentation tank;

[0046] When aerobic fermentation is carried out, clean air can be evenly mixed into the substances in the fermentation tank through the stirring rod during the stirring process, ensuring the substance needs inside the fermentation tank during aerobic fermentation;

[0047] When cleaning, water enters the stirring shaft and the stirring rod through the gas-liquid inlet pipe, and the stirring rod rotates to spray the water evenly into the inner tank of the fermentation tank, achieving efficient and dead-angle cleaning of the inner tank.

[0048] Sterilization can also be achieved by passing high-temperature steam into the inner container through the stirring shaft and the stirring rod.

[0049] Specifically, a sealed bearing 12 is installed on the inner side wall of the upper end of the stirring shaft 1301, the outer ring of the sealed bearing 12 is sealedly connected to the inner side wall of the stirring shaft 1301, and the inner ring of the sealed bearing 12 is sealedly connected to the gas-liquid inlet pipe 16;

[0050] The gas-liquid inlet pipe 16 is fixedly mounted on the upper surface of the fermentation tank 1, so that the position of the gas-liquid inlet pipe remains fixed during operation, and further ensures the sealing performance during the connection process.

[0051] Specifically, the fermentation tank 1 is made of stainless steel as a whole, and an electromagnetic coil is arranged on the inner surface of the inner tank, and the electromagnetic coil is electrically connected to an external power supply.

[0052] Specifically, a guide rail 14 is installed on the outer wall of the stirring shaft 1301 , and a filter plate 15 is mounted on the outer peripheral surface of the stirring shaft 1301 , and the filter plate 15 abuts against the guide rail 14 .

[0053] Specifically, the filter plate 15 includes a plate body 1501, on which a plurality of fan-shaped through holes are evenly distributed in a circle, a filter screen 1502 is installed on the fan-shaped through holes, a stirring shaft through hole is provided at the center of the plate body 1501, and guide grooves 1503 are evenly provided around the stirring shaft through hole, and a stirring rod through groove 1504 is provided between two adjacent fan-shaped through holes, and the outer peripheral surface of the plate body 1501 is in contact with the electromagnetic coil, and after the electromagnetic coil is energized, the current flows from one of the electromagnetic coils through the plate body to the other electromagnetic coil, and the Lorentz force is used to make the plate body slide downward along the guide rail 14 to scrape the residual substances on the inner tank, and the filter screen 1502 is used to achieve preliminary solid-liquid separation of the substances in the inner tank; the plate body is moved up and down along the guide rail by changing the current direction between the electromagnetic coils, and the filtering and recovery operations of the filter plate are completed. The filter plate is moved up and down by the Lorentz force during operation, and no redundant driving device is used, thereby reducing the sanitary dead corners during the cleaning process;

[0054] Furthermore, an electromagnet is installed on the stirring shaft, which can attract the filter plate to the upper end of the stirring shaft.

[0055] Specifically, the liquid supply assembly includes a condensing water tank 20 and a heating water tank 21, the condensing water tank 20 is connected to the heating water tank 21, the water inlet of the condensing water tank 20 is connected to the outlet of the water pipe 4 through the cold pipe 19, and one water outlet of the heating water tank 21 is connected to the inlet of the water pipe 4 through the heat pipe 22;

[0056] Another water outlet of the heating water tank 21 is connected to the three-way valve 17 through the water supply pipe 18;

[0057] The air supply assembly includes an air purification device 5 and a fan 6. The air purification device 5 and the fan 6 are both installed on the side wall of the fermentation tank 1, and the air purification device 5 is connected to the fan 6. The fan 6 is connected to the three-way valve 17 through the air inlet pipe 7, and is connected to the gas-liquid inlet pipe through the three-way valve, so as to facilitate the liquid supply assembly and the air supply assembly to supply gas and liquid to the inside of the fermentation tank, thereby completing the functions of cleaning, high-temperature sterilization and aerobic fermentation. The structure is simple and the operation is convenient.
