Description

Technical Field

[0001] This invention relates to the field of beer fermentation technology, and in particular to a beer microbial conversion fermentation tank and its fermentation process. Background Technology

[0002] In traditional beer fermentation, uneven temperature control and low mixing efficiency often lead to damaged yeast activity and accumulation of byproducts, affecting the flavor and quality stability of the beer. Especially during the primary fermentation stage, the concentrated release of metabolic heat, if not promptly dissipated, easily creates localized high-temperature zones, causing premature yeast aging or the production of undesirable components such as fusel oils. Existing equipment generally relies on external cooling jackets for temperature control, which suffers from drawbacks such as heat transfer lag, condensation on the inner walls, and difficulty in cleaning. This not only makes it difficult to achieve precise temperature control and uniform mixing throughout the entire process, but also easily leads to damaged yeast activity due to uneven temperature control and low mixing efficiency. The accumulation of byproducts seriously affects the flavor and quality stability of beer. At the same time, during the yeast proliferation period, traditional stirring methods cannot ensure sufficient contact between yeast and wort, resulting in uneven distribution of nutrients, which in turn affects the yeast's proliferation efficiency and metabolic activity, leading to slow fermentation start-up and reduced beer production capacity. In addition, in multi-batch continuous fermentation operations, organic deposits are easily left on the inner wall of the tank, breeding miscellaneous bacteria and increasing the risk of cross-contamination, affecting the purity of subsequent batches of fermentation and the consistency of finished product quality. Furthermore, traditional cleaning methods are difficult to completely remove organic deposits, resulting in low cleaning efficiency and time-consuming and energy-intensive cleaning.

[0013] A beer microbial conversion fermentation process, using a beer microbial conversion fermentation tank, specifically includes the following steps: S1, cleaning the tank: The electric valve is closed, and the inlet pipe is connected to an external cleaning liquid storage tank. At this time, the water pump and motor inside the external cleaning liquid storage tank start. The cleaning liquid enters the interior of support pipe one through the inlet pipe and abuts against the electric valve, causing the electric valve to slide downwards via a slide cylinder. Water holes one and four correspond to each other. Support pipe one is connected to the support cylinder through water hole two, allowing the cleaning liquid to spray onto the inner wall of the tank and the interior of the support cylinder. After the motor starts, it rotates forward, driving support pipe one and support pipe two to rotate via a rotating shaft and rotating cylinder, allowing the cleaning liquid to thoroughly clean the inner wall of the tank. As support pipe one rotates with the rotating shaft, the spiral tube drives the support cylinder to move and rotate with support pipe one, continuously covering water hole one. When the spiral tube covers water hole one, the cleaning liquid is sprayed into the interior of the spiral tube and cleans the spiral tube. The inner wall of the tank is cleaned, and the cleaning liquid cleans the inner wall of the support cylinder from all directions through water hole two. During the process of the spiral tube covering water hole one, the alignment of water hole one with the guide groove of the spiral tube changes periodically, so that the cleaning liquid impacts the inside of the spiral tube and the inner wall of the tank in a pulse form, thereby enhancing the cleaning effect on the inner wall of the spiral tube and the inner wall of the tank and effectively removing the attached substances. Through the rotation of support tube one and the rotation of the spiral tube during the cleaning process, the cleaning liquid cleans the inner wall of the spiral tube and the inner wall of the tank from all directions, effectively avoiding cleaning blind spots and improving the uniformity and efficiency of cleaning. At the same time, the continuous coverage of water hole one by the spiral tube makes the cleaning liquid impact the inside of the spiral tube and the inner wall of the tank in a pulse form, thereby enhancing the cleaning effect on the inner wall of the spiral tube and the inner wall of the tank, effectively removing the attached substances, avoiding microbial residues, and further improving the thoroughness of cleaning and the cleanliness of the fermentation environment. After the tank is cleaned, the electric valve is opened, the slide plate is reset, and water hole one and water hole four are staggered, so that the cleaning liquid inside the tank is discharged through discharge pipe one.S2, Yeast Proliferation Phase: After cleaning the inside of the tank, the motor is started. Raw materials and yeast are discharged into the tank through the feed pipe. The motor rotates forward, driving support pipe one and support pipe two to rotate via the rotating shaft and rotating cylinder. The spiral tube drives the support cylinder to move and rotate along with support pipe one. During the process of feeding raw materials and yeast into the tank, support pipe one rotates around the rotating shaft, stirring the mixture inside the tank. This ensures that the raw materials and yeast are in full contact and evenly distributed, promoting rapid yeast proliferation. Simultaneously, the rotation of the spiral tube further stirs the mixture, enhancing the mixing effect and ensuring even distribution of yeast in the culture medium. During the feeding process, support pipe one... The rotation of the support tube and the self-rotation of the spiral tube ensure that the mixture is stirred during the feeding process, guaranteeing full contact and uniform distribution of the raw materials and yeast, promoting rapid yeast proliferation. Simultaneously, the rotation of the spiral tube further improves the uniformity of the mixture, effectively avoiding localized excessively high or low concentrations, ensuring the yeast is always in the optimal growth environment, and improving fermentation efficiency and product quality. S3, Alcoholic Fermentation Period: After feeding, both the drain pipe and the inlet pipe are connected to the coolant storage tank. At this time, the water pump and motor inside the coolant storage tank start. The coolant flows through the inlet pipe sequentially through the support tube one, support tube two, and the drain hole, and from the drain hole to the drain pipe. As the coolant flows through the support tube... During the process of mixing with the support tube 1 and the support tube 2, cooling water drives the rotating drum through the first blade, which in turn drives the second blade to rotate. This causes the second blade to drive the mixture inside the tank to flow from the support tube to the inside of the spiral tube. The mixture then flows from bottom to top on the outside of the support tube 1 and through the third water hole into the tank, effectively forming a dynamic circulation flow. Simultaneously, the spiral tube and the side of the support tube 1 that contacts the spiral tube are open, allowing the mixture to directly contact the side wall of the support tube 1, improving the heat transfer efficiency of the mixture and ensuring a uniform temperature distribution during fermentation. This prevents localized overheating that could affect yeast activity. When the mixture passes the point where the spiral tube contacts the first water hole, it overflows from the spiral tube into the tank, thus achieving a smooth mixing process. The diversion and redistribution of the mixed liquid enhances the fluidity of the liquid inside the tank, effectively improving the uniform cooling and heat exchange of the mixed liquid. The motor starts and drives the rotating shaft to reverse, which in turn drives the movable cylinder to move up and down reciprocally. The movable cylinder drives the spiral tube, support tube one, and support tube two to move laterally, allowing the spiral tube to circulate and cool the mixed liquid at different locations inside the tank. This ensures that the temperature gradient in each area of ​​the tank is minimized, effectively maintaining the stability of the fermentation system and preventing yeast metabolic imbalance caused by temperature differences, further ensuring the smooth progress of alcohol fermentation. S4, Settling Period: After fermentation, the water pump and motor inside the coolant storage tank are turned off, and the mixed liquid inside the tank is allowed to settle.

[0014] Compared with existing technologies, the beneficial effects of this invention are as follows: 1. During the cleaning process, the rotation of the support tube and the rotation of the spiral tube allow the cleaning liquid to thoroughly clean the inner walls of the spiral tube and the tank, effectively avoiding blind spots and improving the uniformity and efficiency of cleaning. At the same time, the continuous coverage of the water hole 1 by the spiral tube allows the cleaning liquid to impact the inside of the spiral tube and the inner wall of the tank in a pulsed manner, thereby enhancing the cleaning effect on the inner walls of the spiral tube and the tank, effectively removing attachments, avoiding microbial residues, and further improving the thoroughness of cleaning and the cleanliness of the fermentation environment.

[0015] 2. During the feeding process, the rotation of the support tube and the rotation of the spiral tube ensure that the support tube stirs the mixture, ensuring that the raw materials and yeast are in full contact and evenly distributed, promoting rapid yeast proliferation. The rotation of the spiral tube further improves the uniformity of the mixture, effectively avoiding local concentrations that are too high or too low, ensuring that the yeast is always in the optimal growth environment, and improving fermentation efficiency and product quality.

[0016] 3. The design of the spiral tube and the support tube having an open side allows the mixed liquid to directly contact the side wall of the support tube during circulation, improving the heat transfer efficiency of the mixed liquid, making the temperature distribution uniform during fermentation, and avoiding local overheating that could affect yeast activity.

[0017] 4. By overflowing the mixture during the circulation process, when the mixture comes into contact with the water hole through the spiral tube, it will overflow from the inside of the spiral tube into the inside of the tank, thereby realizing the diversion and redistribution of the mixture, enhancing the fluidity of the mixture inside the tank, and effectively improving the uniform cooling and heat exchange of the mixture.

[0018] 5. The spiral tube, support tube one, and support tube two move laterally back and forth, so that the spiral tube circulates and cools the mixed liquid in different positions inside the tank, ensuring that the temperature gradient in each area of ​​the tank is minimized, effectively maintaining the stability of the fermentation system, and preventing yeast metabolic imbalance caused by temperature difference, thus further ensuring the smooth progress of alcohol fermentation.

Therefore, they should not be construed as limitations on this invention.

[0023] Reference Figure 1 - Figure 12 As shown, a beer microbial conversion fermentation tank includes a tank body 1. An agitator is movably installed inside the tank body 1. The agitator includes a rotating shaft 21, four support pipes 22 and four support pipes 221. A mounting base 125 is integrally formed at the bottom of the tank body 1. The rotating shaft 21 is rotatably mounted above the mounting base 125. The four support pipes 22 and four support pipes 221 correspond one-to-one and are evenly distributed in a circular shape on the outside of the rotating shaft 21. A rotating cylinder 231 is rotatably mounted between the support pipes 22 and the support pipes 221. Two rotating cylinders 222, one above the other, are rotatably mounted on the side wall of the rotating shaft 21. The support pipes 22 and 221 are slidably mounted on the side walls of the two rotating cylinders 222. An annular groove 227 is opened on the inner side of each of the two rotating cylinders 222. The support pipes 22 and 221 are respectively connected to the two annular grooves 227. A temperature control component is movably installed on the outside of each support tube 22. The temperature control component includes a spiral tube 23, which is rotatably fitted onto the outside of the support tube 22. The spiral tube 23 is open to one side of the support tube 22. A support cylinder 236 is integrally formed at the bottom of the spiral tube 23, and a rotating cylinder 231 is located inside the support cylinder 236.

[0024] like Figure 2 , Figure 3 and Figure 5 As shown, the rotating shaft 21 has a drain hole 213 and a water inlet hole 214 inside. A fixed cylinder 13 is fixedly installed inside the tank body 1. The rotating shaft 21 is rotatably installed inside the fixed cylinder 13. The fixed cylinder 13 is located above the two rotating cylinders 222. The fixed cylinder 13 has two annular grooves 131, one above the other. The two ends of the drain hole 213 are respectively connected to the lower annular groove 131 and the lower annular groove 227 inside the lower rotating cylinder 222. The two ends of the water inlet hole 214 are respectively connected to the upper annular groove 131 and the upper annular groove 227 inside the upper rotating cylinder 222.

[0025] like Figure 1 , Figure 5 and Figure 6 As shown, a drain pipe 123 is fixedly connected to the side wall of the lower annular groove 131, and a water inlet pipe 124 is fixedly connected to the side wall of the upper annular groove 131. Both the drain pipe 123 and the water inlet pipe 124 pass through the top of the tank body 1 to the outside. A discharge port 126 is opened at the bottom of the mounting base 125. A discharge pipe 11 is fixedly connected to the bottom of the tank body 1. The discharge pipe 11 and the discharge port 126 are connected. A feed pipe 121 and a discharge pipe 122 are fixedly connected to the side wall of the tank body 1.

[0026] During the cleaning of tank 1, the water inlet pipe 124 is connected to the external cleaning liquid storage tank. During the fermentation process, the water inlet pipe 124 is connected to the coolant storage tank, and the drain pipe 123 is always connected to the coolant storage tank. After the external liquid enters the upper annular groove 131, the liquid flows through the water inlet hole 214 to the interior of the upper annular groove 227, causing the liquid to flow into the interior of the support pipe 1 22 and the support pipe 2 221. When the liquid flows through the support pipe 2 221 to the interior of the lower annular groove 227, the liquid flows through the drain hole 213 to the interior of the lower annular groove 131 and is discharged through the drain pipe 123.

[0027] like Figure 3 , Figure 5 , Figure 8 and Figure 11 As shown, the rotating cylinder 222 located below is rotatably mounted on the top of the mounting base 125. A ratchet 228 is provided between the rotating cylinder 222 and the mounting base 125. Spring locking blocks 224 are slidably installed inside the two rotating cylinders 222. A locking groove 215 is opened on the side wall of the rotating shaft 21. The spring locking block 224 is slidably inserted into the side wall of the locking groove 215. An electric motor 211 is fixedly installed on the top of the tank body 1. The output shaft of the electric motor 211 is fixedly connected to the rotating shaft 21.

[0028] When the motor 211 drives the rotating shaft 21 to rotate forward, the ratchet 228 is in the unlocked state, so that the rotating shaft 21 drives the rotating cylinder 222 to rotate forward through the spring locking block 224. The rotating cylinder 222 drives the first support tube 22 and the second support tube 221 to rotate. When the motor 211 drives the rotating shaft 21 to rotate in reverse, the ratchet 228 is in the locked state, so that the spring locking block 224 slides out of the lock groove 215 during the reverse rotation of the rotating shaft 21. At this time, the rotating cylinder 222, the first support tube 22 and the second support tube 221 are in a stationary state.

[0029] like Figure 2 , Figure 3 and Figures 7-9 As shown, a gear 132 is fixedly installed at the bottom of the fixed cylinder 13, and a gear 3 134 is rotatably installed on the side wall of each support tube 22. The gear 3 134 meshes with the gear 132. A gear 2 133 is fixedly connected below the gear 3 134. A gear 4 232 is fixedly installed at the top of the spiral tube 23. The gear 2 133 meshes with the gear 4 232.

[0030] During the process of rotating the cylinder 222 driving the support tube 1 22 and the support tube 2 221 to rotate, the gear 1 132 drives the gear 3 134 to rotate, the gear 3 134 drives the gear 2 133 to rotate, which in turn drives the gear 4 232 to rotate, and the gear 4 232 drives the spiral tube 23 to rotate, so that the spiral tube 23 rotates on its own axis during the process of the support tube 1 22 driving the spiral tube 23 to move.

[0031] like Figure 4 , Figure 9 and Figure 10 As shown, support tube 1 22 and support tube 221 are both connected to the inner side of rotating cylinder 231. Several uniformly distributed blades 1 234 are integrally formed on the inner side of rotating cylinder 231. Support cylinder 236 and rotating cylinder 231 are connected to the inside of spiral tube 23. Several uniformly distributed blades 235 are welded to the outer side of rotating cylinder 231. Blades 235 are located inside support cylinder 236. Through grooves 226 are opened on the side wall of support cylinder 236 and the side wall of support tube 221. Water hole 3 233 is opened on the top of spiral tube 23.

[0032] During the process of the liquid flowing through the inside of the first support pipe 22 and the second support pipe 221, the liquid passes through the inside of the rotating drum 231, causing the rotating drum 231 to rotate through the first blade 234. The first blade 234 and the second blade 235 are tilted in opposite directions, causing the second blade 235 to drive the mixture inside the support cylinder 236 to flow upward. After the mixture flows to the top of the spiral tube 23, it flows into the inside of the tank 1 through the third water hole 233, so that the mixture circulates inside the tank 1.

[0033] like Figure 3 , Figure 4 and Figure 9 As shown, a sliding plate 32 is slidably installed inside the support tube 22. The side wall of the sliding plate 32 has several evenly distributed water holes 321. The side wall of the support tube 22 has several evenly distributed water holes 223 and one water hole 225. Water holes 321 and water holes 223 correspond one-to-one. Water hole 225 is connected to the support cylinder 236. The top and bottom of the sliding plate 32 are integrally formed with a sliding cylinder 324. A spring 322 is provided between the upper sliding cylinder 324 and the inner wall of the support tube 22. The lower sliding cylinder 324 is located above the rotating cylinder 231. An electric valve 323 is provided inside the lower sliding cylinder 324.

[0034] The electric valve 323 is closed only when cleaning the tank 1. When the cleaning fluid enters the interior of the support tube 22, it abuts against the electric valve 323, causing the slide plate 32 to slide downward. At this time, the water hole 321 corresponds to the water hole 223. The interior of the support cylinder 236 is connected to the interior of the support tube 22 through the water hole 225, so that the cleaning fluid is flushed to the inner wall of the tank 1 and the inner wall of the support cylinder 236.

[0035] like Figure 4 , Figure 7 , Figure 11 and Figure 12 As shown, a movable cylinder 31 is movably fitted on the outer side of the rotating shaft 21, and a collar 312 is rotatably fitted on the outer side of each support cylinder 236. A connecting rod 311 is provided between the collar 312 and the movable cylinder 31. A bidirectional sliding groove 212 is provided on the outer side of the rotating shaft 21, and a sliding ball 313 is integrally formed on the inner side of the movable cylinder 31. The sliding ball 313 is slidably installed inside the bidirectional sliding groove 212.

[0036] When the rotating shaft 21 reverses and the first support tube 22 is stationary, the rotating shaft 21 drives the movable cylinder 31 to reciprocate up and down through the bidirectional sliding groove 212 and the sliding ball 313. The movable cylinder 31 drives the spiral tube 23 to reciprocate laterally through the connecting rod 311. The spiral tube 23 drives the first support tube 22 and the second support tube 221 to reciprocate.

[0037] A beer microbial conversion fermentation process, which uses the above-mentioned beer microbial conversion fermentation tank, specifically includes the following steps: S1, cleaning the tank 1: closing the electric valve 323, connecting the water inlet pipe 124 to the external cleaning liquid storage tank, at this time the water pump and motor 211 inside the external cleaning liquid storage tank are started, the cleaning liquid enters the interior of the support pipe 1 22 through the water inlet pipe 124 and abuts against the electric valve 323, causing the electric valve 323 to drive the slide plate 32 downward through the slide cylinder 324, at this time the water hole 1 223 and the water hole 4 321 correspond, the support pipe 1 22 through the water hole 2 25 is connected to the support cylinder 236, allowing the cleaning fluid to be sprayed onto the inner wall of the tank 1 and the interior of the support cylinder 236. After the motor 211 starts, it rotates forward, driving the support pipe 1 22 and support pipe 221 to rotate via the rotating shaft 21 and the rotating cylinder 222. This allows the cleaning fluid to clean the inner wall of the tank 1 from all angles. As the support pipe 1 22 rotates with the rotating shaft 21, the spiral tube 23 drives the support cylinder 236 to move and rotate along with the support pipe 1 22, continuously covering the water hole 223. When the spiral tube 23 covers the water hole 223, the cleaning fluid is sprayed into the spiral tube. The cleaning fluid cleans the inside of the spiral tube 23 and its inner wall. Simultaneously, the cleaning fluid, through water hole 225, thoroughly cleans the inner wall of the support cylinder 236. As the spiral tube 23 covers the water hole 223, the alignment of the water hole 223 with the guide groove of the spiral tube 23 changes periodically, causing the cleaning fluid to impact the inside of the spiral tube 23 and the inner wall of the tank 1 in a pulsed manner. This enhances the cleaning effect on the inner walls of the spiral tube 23 and the tank 1, effectively removing deposits. During the cleaning process, the rotation of the support tube 22 and the rotation of the spiral tube 23 further clean the inner walls of the spiral tube 23 and the tank 1. The comprehensive cleaning effectively avoids blind spots and improves the uniformity and efficiency of cleaning. At the same time, the spiral tube 23 continuously covers the water hole 223, so that the cleaning liquid impacts the inside of the spiral tube 23 and the inner wall of the tank 1 in a pulse form, thereby enhancing the cleaning effect on the inner wall of the spiral tube 23 and the inner wall of the tank 1, effectively removing the attached substances, avoiding microbial residues, and further improving the thoroughness of cleaning and the cleanliness of the fermentation environment. After the tank 1 is cleaned, the electric valve 323 is opened, the slide plate 32 is reset, and the water hole 223 and the water hole 321 are staggered to discharge the cleaning liquid inside the tank 1 through the discharge pipe 11.S2, Yeast Proliferation Period: After cleaning the inside of tank 1, motor 211 starts, and raw materials and yeast are discharged into the inside of tank 1 through feed pipe 121. After starting, motor 211 rotates forward, and drives support pipe one 22 and support pipe two 221 to rotate through rotating shaft 21 and rotating cylinder 222. Spiral tube 23 drives support cylinder 236 to move and rotate with support pipe one 22. During the process of raw materials and yeast being discharged into tank 1, support pipe one 22 rotates around rotating shaft 21 and stirs the mixture inside tank 1, so that the raw materials and yeast are in full contact and evenly distributed. This process promotes rapid yeast proliferation, while the rotation of the spiral tube 23 further stirs the mixture, enhancing the mixing effect and ensuring uniform distribution of yeast in the culture medium. During the feeding process, the rotation of the support tube 22 and the rotation of the spiral tube 23 ensure that the raw materials and yeast are in full contact and evenly distributed, promoting rapid yeast proliferation. At the same time, the rotation of the spiral tube 23 further improves the uniformity of mixing, effectively avoiding local concentrations that are too high or too low, ensuring that the yeast is always in the optimal growth environment, and improving fermentation efficiency and product quality.S3, Alcoholic Fermentation Period: After feeding is completed, both drain pipe 123 and inlet pipe 124 are connected to the coolant storage tank. At this time, the water pump and motor 211 inside the coolant storage tank start. The coolant flows through the inlet pipe 124 sequentially through the interior of support pipe 1 22, support pipe 2 221, and drain hole 213, and flows from the interior of drain hole 213 into the interior of drain pipe 123. During the process of the coolant flowing through support pipe 1 22 and support pipe 2 221, the cooling water drives the rotating drum 23 through blade 1 234. 1. The rotating drum 231 drives the blades 235 to rotate, causing the mixed liquid inside the tank 1 to flow from the support cylinder 236 to the inside of the spiral tube 23. This causes the mixed liquid to flow from bottom to top on the outside of the support tube 22 and flow into the inside of the tank 1 through the water hole 233, effectively forming a dynamic circulation flow. Simultaneously, the spiral tube 23 and the support tube 22 are open on the contact side, allowing the mixed liquid to directly contact the side wall of the support tube 22, improving the heat transfer efficiency of the mixed liquid. The temperature is evenly distributed during fermentation to avoid localized overheating that could affect yeast activity. When the mixture passes through the spiral tube 23 and contacts the water hole 223, it overflows from the spiral tube 23 into the tank 1, thus achieving diversion and redistribution of the mixture, enhancing its fluidity, and effectively improving uniform cooling and heat exchange. The motor 211 starts and drives the rotating shaft 21 to reverse, which in turn drives the movable cylinder 31 to move up and down reciprocally. The movable cylinder 31 drives the spiral tube 23, support tube 22, and support tube 221 to move laterally, allowing the spiral tube 23 to circulate and cool the mixture at different locations within the tank 1. This minimizes the temperature gradient in each area of ​​the tank, effectively maintaining the stability of the fermentation system and preventing yeast metabolic imbalance caused by temperature differences, further ensuring the smooth progress of alcohol fermentation. S4, Settling Period: After fermentation, the water pump and motor 211 inside the coolant storage tank are turned off, and the mixture inside the tank 1 is allowed to settle.

10. A microbial conversion fermentation process for beer, characterized in that: The fermentation process uses a beer microbial conversion fermentation tank as described in claim 9, and specifically includes the following steps: S1. Cleaning the tank (1): Close the electric valve (323), connect the water inlet pipe (124) to the external cleaning fluid storage tank. At this time, the water pump and motor (211) inside the external cleaning fluid storage tank are started. The cleaning fluid enters the interior of the support pipe (22) through the water inlet pipe (124) and abuts against the electric valve (323), causing the electric valve (323) to drive the slide plate (32) to slide downward through the slide cylinder (324). At this time, the water hole one (223) and the water hole four (321) correspond to each other. The support pipe one (22) is connected to the support cylinder (236) through the water hole two (225), so that the cleaning fluid flows into the inner wall of the tank (1) and the support cylinder (236). The cleaning fluid is sprayed internally. After the motor (211) starts, it rotates forward and drives the support pipe 1 (22) and support pipe 2 (221) to rotate through the rotating shaft (21) and rotating cylinder (222), so that the cleaning fluid cleans the inner wall of the tank (1) in all directions. As the support pipe 1 (22) rotates with the rotating shaft (21), the spiral tube (23) drives the support cylinder (236) to move and rotate with the support pipe 1 (22), so that the spiral tube (23) continuously covers the water hole 1 (223). When the spiral tube (23) covers the water hole 1 (223), the cleaning fluid is sprayed into the interior of the spiral tube (23) and cleans the inner wall of the spiral tube (23). During cleaning, the cleaning fluid cleans the inner wall of the support cylinder (236) through water hole two (225). As the spiral tube (23) covers water hole one (223), the alignment of water hole one (223) with the guide groove of the spiral tube (23) changes periodically, causing the cleaning fluid to impact the inside of the spiral tube (23) and the inner wall of the tank (1) in a pulse form, thereby enhancing the cleaning effect on the inner wall of the spiral tube (23) and the inner wall of the tank (1) and effectively removing the attached substances. During the cleaning process, the rotation of support tube one (22) and the rotation of the spiral tube (23) enable the cleaning fluid to clean the inner wall of the spiral tube (23) and the inner wall of the tank (1) in an all-round way. Effectively avoid cleaning blind spots, improve the uniformity and efficiency of cleaning, and continuously cover water hole one (223) through spiral tube (23) so that the cleaning liquid impacts the inside of spiral tube (23) and the inner wall of tank (1) in a pulse form, thereby enhancing the cleaning effect on the inner wall of spiral tube (23) and tank (1), effectively removing attachments, avoiding microbial residues, further improving the thoroughness of cleaning and the cleanliness of fermentation environment. After cleaning the tank (1), open the electric valve (323), reset the slide plate (32), and water hole one (223) and water hole four (321) intersect each other, and discharge the cleaning liquid inside the tank (1) through discharge pipe one (11); S2, Yeast Proliferation Period: After cleaning the inside of the tank (1), the motor (211) is started. The raw materials and yeast are discharged into the inside of the tank (1) through the feed pipe (121). After the motor (211) starts, it rotates forward and drives the support pipe one (22) and support pipe two (221) to rotate through the rotating shaft (21) and rotating cylinder (222). The spiral tube (23) drives the support cylinder (236) to move and rotate with the support pipe one (22). During the process of the raw materials and yeast being discharged into the tank (1), the support pipe one (22) rotates around the rotating shaft (21) and stirs the mixture inside the tank (1), so that the raw materials and yeast can be mixed together. The yeast is fully in contact and evenly distributed, promoting rapid yeast proliferation. At the same time, the rotation of the spiral tube (23) further stirs the mixture, which further enhances the mixing effect and ensures that the yeast is evenly distributed in the culture medium. During the feeding process, the rotation of the support tube (22) and the rotation of the spiral tube (23) make the support tube (22) stir the mixture, ensuring that the raw materials and yeast are fully in contact and evenly distributed, promoting rapid yeast proliferation. At the same time, the rotation of the spiral tube (23) further improves the uniformity of the mixture, effectively avoiding the phenomenon of excessively high or low local concentrations, ensuring that the yeast is always in the best growth environment, and improving fermentation efficiency and product quality. S3, Alcoholic Fermentation Period: After feeding is completed, both the drain pipe (123) and the inlet pipe (124) are connected to the coolant storage tank. At this time, the water pump and motor (211) inside the coolant storage tank are started. The coolant flows through the inlet pipe (124) sequentially through the interior of support pipe one (22), support pipe two (221), and drain hole (213), and flows from the interior of drain hole (213) to the interior of drain pipe (123). During the process of the coolant flowing through support pipe one (22) and support pipe two (221), the cooling... Water drives the rotating drum (231) to rotate via blade one (234), and the rotating drum (231) drives blade two (235) to rotate, causing blade two (235) to drive the mixture inside the tank (1) to flow from the support cylinder (236) to the inside of the spiral tube (23). This causes the mixture to flow from bottom to top on the outside of the support tube one (22) and flow into the inside of the tank (1) through water hole three (233), effectively forming a dynamic circulation flow. At the same time, the contact side between the spiral tube (23) and the support tube one (22) is open. The opening shape allows the mixture to directly contact the side wall of the support tube (22), improving the heat transfer efficiency of the mixture and ensuring a uniform temperature distribution during fermentation. This prevents local overheating from affecting yeast activity. When the mixture passes through the spiral tube (23) and contacts the water hole (223), it overflows from the spiral tube (23) into the tank (1), thus achieving the diversion and redistribution of the mixture, enhancing the fluidity of the mixture inside the tank (1), and effectively improving the uniform cooling and heat exchange of the mixture. The motor (211) starts. And drive the rotating shaft (21) to reverse, the rotating shaft (21) drives the movable cylinder (31) to move up and down back and forth, the movable cylinder (31) drives the spiral tube (23), support tube one (22) and support tube two (221) to move back and forth laterally, so that the spiral tube (23) circulates and cools the mixed liquid in different positions inside the tank (1), ensuring that the temperature gradient in each area of ​​the tank is minimized, effectively maintaining the stability of the fermentation system, while preventing yeast metabolism imbalance caused by temperature difference, and further ensuring the smooth progress of alcohol fermentation; S4. Settling period: After fermentation, the water pump and motor (211) inside the coolant storage tank are turned off, and the mixture inside the tank (1) is allowed to settle.
