Description

Technical Field

[0001] This utility model relates to the field of probiotic production technology, specifically to a sealed fermentation tank for fermenting probiotic beverages. Background Technology

[0002] Probiotic drinks are generally dairy products with added probiotics. The fermentation of dairy products by probiotics can convert some lactose into lactic acid and hydrolyze proteins, while also increasing the amount of soluble calcium, phosphorus and certain B vitamins.

[0003] For example, Chinese Patent (CN216445330U) discloses a sealed fermentation tank for fermenting probiotic beverages, relating to the field of beverage production and processing. This sealed fermentation tank for fermenting probiotic beverages has a tank body with a groove at the top. A push plate is movably inserted into the inner wall of the groove. This sealed fermentation tank for fermenting probiotic beverages utilizes a rotating column to drive a moving block backward, causing the top of a push support rod to move upward, thus moving the push plate upward. Furthermore, by setting a silicone pad that is tightly fitted to the inner wall of the tank, the silicone pad pushes the fermented material adhering to the inner wall of the tank upward, making it convenient for the user to remove the fermented material from the tank while preventing the fermented material from sticking to the inner wall and mixing with other fermented materials.

[0004] Since probiotics require stirring during fermentation, the above-mentioned methods still require manual stirring. Manual stirring is not only inefficient but also increases labor costs. During manual stirring, the operator's hands or tools may introduce contaminants, increasing the risk of contamination and affecting product quality. Furthermore, the silicone pad may deform after prolonged use, resulting in a poor seal between the silicone pad and the tank. Fermentation products can easily enter the area under the silicone pad through gaps, potentially damaging the equipment. To address these issues, a sealed fermentation tank for fermenting probiotic beverages is proposed. Utility Model Content

[0005] To address the aforementioned technical problems, a sealed fermentation tank for fermenting probiotic beverages is provided. This solves the problem that current solutions require manual stirring of probiotics during fermentation, which is inefficient, increases labor costs, and risks introducing contaminants through operator's hands or tools, affecting product quality. Furthermore, the silicone gasket may deform after prolonged use, resulting in a loose seal between the gasket and the tank, allowing fermentation products to easily seep under the gasket and damage the equipment.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a sealed fermentation tank for fermenting probiotic beverages, comprising a fermentation vessel, an insulation cylinder fixedly connected to the outside of the fermentation vessel, a cavity formed between the fermentation vessel and the insulation cylinder, a heating wire disposed inside the cavity, a lid fixedly connected to the top of the fermentation vessel by bolts, a cleaning assembly disposed inside the fermentation vessel, a thermometer fixedly connected to the front side of the top of the lid, a pressure relief pipe fixedly connected to the top of the lid and the right side of the thermometer, a pressure relief valve fixedly connected to the end of the pressure relief pipe, a pressure gauge fixedly connected to the end of the pressure relief pipe and above the pressure relief valve, a first micro switch fixedly connected to the front and rear sides of the lower part of the fermentation vessel, and a second micro switch fixedly connected to the front and rear sides of the upper part of the fermentation vessel.

[0007] Preferably, the cleaning component includes a support frame, which is fixedly connected to the middle position of the top of the reactor lid. A servo motor is fixedly connected above the support frame. The output end of the servo motor passes through the top of the reactor lid and is fixedly connected to a stirring shaft inside the fermentation vessel. A first pulley is fixedly connected to the outer surface of the stirring shaft and the top of the reactor lid.

[0008] Preferably, a threaded rod is rotatably connected to the left side of the reactor lid, and a scraping ring is threadedly connected to the surface of the threaded rod. A guide rod is fixedly connected to the bottom right side of the reactor lid, and the right side of the scraping ring is slidably connected to the guide rod. A support base for supporting the threaded rod and the guide rod is also fixedly connected to the lower part of the inside of the fermentation vessel.

[0009] Preferably, a second pulley is fixedly connected to the top of the threaded rod, and the second pulley is connected to the first pulley via a synchronous belt.

[0010] Preferably, a water inlet pipe is fixedly connected to the upper left side of the insulation cylinder, and a water outlet pipe is fixedly connected to the upper right side of the insulation cylinder.

[0011] Preferably, a feed pipe is fixedly connected to the rear side of the top of the reactor lid, and a discharge pipe is fixedly connected to the center of the bottom of the fermentation reactor.

[0012] Preferably, the bottom of the fermentation vessel is fixedly connected with support legs for support.

[0013] Compared with the prior art, the advantages of this utility model are as follows: By setting up a cleaning component, the stirring shaft can reciprocate under the cooperation of the first and second microswitches to stir the fermentation material. This prevents material from accumulating in certain dead corners or non-flowing areas of the container due to stirring in one direction, forming sediment, which would affect the activity of probiotics. This improves the stirring efficiency, makes the distribution of dissolved oxygen and nutrients more uniform, and improves the quality of fermentation. Furthermore, when the stirring shaft rotates, the scraping ring can move up and down to scrape off the fermentation material adhering to the inner wall of the fermentation vessel. The scraping ring can effectively remove the material adhering to the vessel wall during fermentation, allowing the stirrer to continuously and fully contact the fermentation liquid, ensuring the stability of the stirring and mixing effect. This helps to maintain the uniform distribution of the culture medium and probiotics, reduce material waste, and thus improve the efficiency of the fermentation process. In terms of temperature control, a water bath heating method is adopted. Water bath heating, through the high heat capacity of water, can provide a relatively uniform heat source, ensuring a uniform temperature distribution inside the fermentation vessel. Compared to direct heating, water bath heating can effectively avoid localized excessively high or low temperatures, thus preventing temperature fluctuations from affecting the growth and metabolic activities of probiotics.

[0022] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0023] Reference Figure 1-6 As shown, a sealed fermentation tank for fermenting probiotic beverages includes a fermentation vessel 1, with an insulation cylinder 2 fixedly connected to the outside of the fermentation vessel 1. A cavity is formed between the fermentation vessel 1 and the insulation cylinder 2, and a heating wire 9 is installed inside the cavity. The insulation cylinder 2 on the outside of the fermentation vessel 1 is designed to form an effective heat insulation layer, which can reduce the influence of the external environment on the temperature of the fermentation process and ensure that the fermentation process is carried out under stable temperature conditions. Meanwhile, the heating wire 9 inside the cavity can precisely control the fermentation temperature to meet the different temperature requirements of probiotic fermentation. The top of the fermentation vessel 1 is fixedly connected to the vessel lid 3 by bolts. The fermentation vessel 1 is equipped with a cleaning component 4. A thermometer 6 is fixedly connected to the front side of the top of the vessel lid 3. A pressure relief pipe 5 is fixedly connected to the top of the vessel lid 3 and the right side of the thermometer 6. A pressure relief valve 15 is fixedly connected to the end of the pressure relief pipe 5. A pressure gauge 14 is fixedly connected to the end of the pressure relief pipe 5 and above the pressure relief valve 15. The setting of the pressure relief pipe 5 and the pressure relief valve 15 can release the pressure inside the tank in time during the fermentation process to prevent equipment damage or safety accidents caused by excessive pressure. The first micro switch 12 is fixedly connected to the front and rear sides of the lower part of the fermentation vessel 1. The second micro switch 13 is fixedly connected to the front and rear sides of the upper part of the fermentation vessel 1. Both the first micro switch 12 and the second micro switch 13 are waterproof touch switches.

[0024] Specifically, the cleaning component 4 includes a support frame 401, which is fixedly connected to the middle position of the top of the lid 3. A servo motor 402 is fixedly connected above the support frame 401. The output end of the servo motor 402 passes through the top of the lid 3 and is fixedly connected to a stirring shaft 403 inside the fermentation vessel 1. A first pulley 404 is fixedly connected to the outer surface of the stirring shaft 403 and the top of the lid 3.

[0025] Specifically, a threaded rod 405 is rotatably connected to the left side of the lid 3, and a scraping ring 408 is threadedly connected to the surface of the threaded rod 405. A guide rod 407 is fixedly connected to the bottom right side of the lid 3. The right side of the scraping ring 408 is slidably connected to the guide rod 407. A support seat 7 for supporting the threaded rod 405 and the guide rod 407 is also fixedly connected to the lower part of the inside of the fermentation vessel 1.

[0026] Specifically, a second pulley 406 is fixedly connected to the top of the threaded rod 405. The second pulley 406 is connected to the first pulley 404 via a synchronous belt. The cleaning component 4 drives the stirring shaft 403 to stir via a servo motor 402. This not only achieves uniform mixing of the fermented material, but also cleverly drives the threaded rod 405 and the scraping ring 408 to move up and down through the synchronous belt drive of the first pulley 404 and the second pulley 406. This design not only simplifies the equipment structure, but also achieves the dual functions of stirring and scraping, greatly improving the cleaning efficiency and fermentation effect of the equipment.

[0027] Specifically, a water inlet pipe 10 is fixedly connected to the upper left side of the insulation cylinder 2, and a water outlet pipe 11 is fixedly connected to the upper right side of the insulation cylinder 2. The design of the water inlet pipe 10 and the water outlet pipe 11 on the insulation cylinder 2 facilitates the injection and discharge of clean water, thereby realizing flexible control of the heating wire 9.

[0028] Preferably, a feed pipe 8 is fixedly connected to the rear top of the lid 3, and a discharge pipe 16 is fixedly connected to the center of the bottom of the fermentation vessel 1. The design of the feed pipe 8 at the top of the lid 3 and the discharge pipe 16 at the bottom of the fermentation vessel 1 makes it very convenient to add raw materials and discharge fermented products. This design not only improves the production efficiency of the equipment, but also helps to maintain the cleanliness and hygiene of the fermentation environment.

[0029] Specifically, support legs 17 are fixedly connected around the bottom of the fermentation vessel 1. The support legs 17 around the bottom of the fermentation vessel 1 not only provide stable support for the equipment, but also help to maintain the balance and stability of the equipment. This design makes it less likely for the equipment to shake or tilt during the fermentation process, thus ensuring the smooth progress of the fermentation process.

[0030] Working principle: When fermenting probiotics, raw materials are first injected into the feed pipe 8 and then sealed. Water is injected into the cavity through the water inlet pipe 10. The water is heated by the heating wire 9 to maintain the required fermentation temperature inside the fermentation vessel 1. When stirring is needed, the servo motor 402 drives the stirring shaft 403 to stir the fermenting material. The rotation of the stirring shaft 403 synchronously drives the second pulley 406 to rotate via the first pulley 404 and the belt, which in turn drives the threaded rod 405 to rotate. Under the threaded engagement, the scraping ring 408 moves up and down. When the 05 rotates clockwise, it drives the scraping ring 408 to move downward. When the scraping ring 408 touches the first micro switch 12, the output end of the servo motor 402 will reverse and drive the threaded rod 405 to rotate counterclockwise, causing the scraping ring 408 to move upward. When the scraping ring 408 touches the second micro switch 13, the scraping ring 408 will move downward again. The stirring shaft 403 stirs the fermented material through this back and forth rotation. At the same time, the scraping ring 408 can also scrape off the fermented material adhering to the inner wall of the fermentation vessel 1 by moving up and down, preventing the fermented material from adhering to the inside of the fermentation vessel 1.
