Description

Technical Field

[0001] This invention belongs to the field of fermentation, specifically relating to a fermentation device and fermentation process for producing pomegranate beverages. Background Technology

[0002] This equipment is a complete set of equipment specifically designed for producing pomegranate fermented beverages through microbial fermentation of pomegranate juice in a closed, sterile environment.

[0003] Patent publication number CN213961640U relates to a probiotic beverage fermentation device, including a storage mechanism with a filter mechanism attached to its inner side. The beneficial effects of this invention are: raw materials enter the storage tank through the feed pipe, are filtered through a filter cloth to remove impurities, and then flow into the bottom of the storage tank. A motor is started to rotate the stirring blades, stirring the bottom of the raw materials to ensure thorough fermentation. After fermentation, the lid is pulled, causing the stirring rod to be withdrawn from the storage tank, simultaneously disengaging the locking block from the first locking slot, thus detaching the filter plate from the storage tank. The filter cloth and stirring blades are then cleaned. This effectively achieves the existing probiotic beverage fermentation device's ability to filter impurities from the raw materials during addition, and to stir the bottom of the storage tank during fermentation to ensure thorough fermentation, while also facilitating the cleaning of the filter plate and stirring blades.

[0004] In existing technologies, probiotic beverage fermentation devices can filter impurities from raw materials when adding them, and can also stir the raw materials at the bottom of the storage tank during fermentation to ensure full fermentation. This also facilitates cleaning of the filter plate and stirring blades. However, during fermentation, ordinary stirring can only cause localized tumbling and lacks the ability to transport materials upwards. The materials can only slowly rise, resulting in a difference in fermentation status between the bottom and top. Additionally, nitrogen needs to be injected into the tank during fermentation, but the nitrogen tends to accumulate at the top of the tank, leading to poor mixing between the nitrogen and the raw materials at the bottom. Summary of the Invention

[0005] The present invention addresses the problem of overly simplistic solutions in existing technologies by providing a significantly different solution. Specifically, the present invention aims to provide a fermentation device and fermentation process for pomegranate beverage production, thereby resolving the issue of discrepancies between the fermentation states of the bottom and top raw materials mentioned in the background.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a fermentation device for pomegranate beverage production, comprising: a fermentation tank; a support frame, the support frame being fixedly installed on the surface of the fermentation tank; a motor, the motor being fixedly installed on the top of the fermentation tank; a feed inlet, the feed inlet being located on the top of the fermentation tank; an air inlet pipe, the air inlet pipe being located on the top of the fermentation tank, and a nitrogen tank being located on the top of the air inlet pipe; a hollow tube being fixedly installed at the output end of the motor, and stirring blades being fixedly installed on the circumferential surface of the hollow tube; a hollow tank being fixedly installed on the inner wall of the fermentation tank; and the hollow tank being connected to... The hollow tube is rotatably connected, and a spiral tube is fixedly installed on the top of the inner wall of the hollow tube. A reciprocating screw is threaded on the inner wall of the spiral tube. A sealing plate is fixedly installed at the bottom of the reciprocating screw. A hollow column is fixedly installed at the bottom of the sealing plate. A circular plate is fixedly installed at the bottom of the hollow column. A long rod is fixedly installed on the inner wall of the hollow tank. The long rod passes through the circular plate. A first-way valve is fixedly installed on the top of the hollow tank. An inlet pipe is fixedly installed on the top of the first-way valve. When the circular plate moves downward, it synchronously drives the sliding rod and the L-shaped frame to move downward. The L-shaped frame pushes the filter cover downward.

[0007] In some embodiments, a filter cover is slidably mounted on the surface of the inlet pipe, a slide rod is fixedly mounted on the bottom of the circular plate, an L-shaped frame is fixedly mounted on the surface of the slide rod, one end of the L-shaped frame away from the slide rod is fixedly mounted on the bottom of the filter cover, and a second one-way valve is fixedly mounted on the surface of the hollow tube. The first one-way valve is used for liquid inlet and only allows liquid to enter, while the second one-way valve is used for liquid outlet and only allows liquid to be discharged.

[0008] A fermentation process for a fermentation device used in pomegranate beverage production includes the following steps: Step 1: Start the motor. The motor drives the hollow tube and stirring blades to rotate synchronously. The rotating stirring blades mix the raw materials inside the fermentation tank, improve the contact efficiency between the raw materials and the inoculum, and promote uniform fermentation. Step 2: As the hollow tube rotates, it drives the spiral tube to rotate synchronously. The spiral tube drives the reciprocating screw, sealing plate, hollow column and circular plate to move up and down along the long rod. When the circular plate moves downward, a negative pressure is formed inside the hollow tank. Under the action of the negative pressure, the raw material liquid at the bottom of the fermentation tank is drawn in through the No. 1 one-way valve and the liquid inlet pipe. Step 3: The raw material liquid enters the hollow tank through the No. 1 one-way valve and the inlet pipe; when the circular plate moves upward, the circular plate squeezes the liquid in the hollow tank and discharges the raw material at the bottom upward through the No. 2 one-way valve, thereby realizing the bottom-to-top reciprocating circulation of raw material in the fermentation tank, avoiding long-term accumulation of raw material in the dead corner area at the bottom of the tank, preventing local fermentation abnormalities, and ensuring the overall fermentation consistency. Step 4: As the circular plate moves downward, it simultaneously drives the sliding rod and L-shaped frame to move downward. The L-shaped frame pushes the filter cover downward. During the downward movement of the filter cover, the pomegranate pulp and seeds are pushed aside, allowing the liquid to enter the filter cover through the gaps. Then, it is sucked into the hollow tank under negative pressure, effectively preventing pomegranate seeds and pulp from clogging the liquid inlet pipe and ensuring the continuous and stable circulation of raw materials.

[0009] In some embodiments, the fermenter is equipped with an extraction device and a regulating device to prevent gas accumulation. The extraction device includes an air inlet, an air inlet groove, and a third one-way valve. The air inlet is fixedly installed on the surface of the hollow tube, and a first one-way air inlet valve is installed inside the air inlet. The air inlet groove is opened on the surface of the spiral tube, and a second one-way air inlet valve is installed inside the air inlet groove. The third one-way valve is located at the bottom of the hollow tank and is used for gas discharge. When the sealing plate moves upward, the sealing plate will squeeze the gas inside the hollow tube into the air inlet groove, and then along the spiral tube and hollow column into the interior of the hollow tank, and then the nitrogen gas is discharged through the third one-way valve.

[0010] In some embodiments, a sliding rod slides through the surface of the hollow tube, a ring is fixedly installed on the top of the sliding rod, a sealing ring is fixedly installed on the inner wall of the air inlet pipe, an L-shaped rod slides through the surface of the sealing ring, and a sealing plug is fixedly installed on the top of the L-shaped rod, so that nitrogen gas enters the fermenter. When the circular plate moves downward, the sealing plug will reseal the sealing ring.

[0011] In some embodiments, a first spring is provided between the hollow tube and the sliding rod, and the sliding rod is reset by the elastic force of the first spring. A second spring is provided between the sealing ring and the L-shaped rod, and the L-shaped rod is reset by the elastic force of the second spring.

[0012] In some embodiments, the adjusting device includes a connecting plate, a connecting frame, and a scraper. The connecting plate is fixedly installed on the circumferential surface of the filter cover, the connecting frame is fixedly installed on the surface of the connecting plate, and the scraper is fixedly installed on the top of the connecting frame. The upward movement of the filter cover drives the connecting plate, the connecting frame, and the scraper to move upward. At the same time, the liquid discharged from the No. 2 one-way valve may splash onto the inner wall of the fermenter.

[0013] In some embodiments, a connecting rod is fixedly installed on the top of the inner wall of the inlet pipe, a short plate is slidably installed on the inner wall of the filter cover, a sliding tube is fixedly installed on the surface of the short plate, a spiral groove is formed on the inner wall of the sliding tube, and a short rod is fixedly installed at the bottom of the connecting rod. When the sliding tube moves downward, it will drive the spiral groove to move upward. When the spiral groove moves upward, it will contact the short rod, and the short rod will rotate against the spiral groove. The rotation of the spiral groove will drive the sliding tube.

[0014] In some embodiments, the short rod slides on the inner wall of the spiral groove, and the scraper contacts the inner wall of the fermenter to scrape the inside of the fermenter.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention utilizes rotating stirring blades to mix the raw materials inside the fermentation tank, improving the contact efficiency between the raw materials and the inoculum, and promoting uniform fermentation. When the circular plate moves downward, a negative pressure is created inside the hollow tank. Under this negative pressure, the raw material liquid from the bottom of the fermentation tank is drawn in through the first one-way valve and the inlet pipe. The raw material liquid then enters the hollow tank through the first one-way valve and the inlet pipe. When the circular plate moves upward, it compresses the liquid inside the hollow tank, and the raw material from the bottom is discharged upward through the second one-way valve. This achieves a reciprocating cycle of raw material being drawn in from the bottom and discharged from the top within the fermentation tank, preventing long-term accumulation of raw material in dead zones at the bottom of the tank, preventing localized fermentation abnormalities, and ensuring overall fermentation consistency.

[0016] 2. This invention, by moving the circular plate downwards, simultaneously drives the sliding rod and L-shaped frame downwards, and the L-shaped frame pushes the filter cover downwards. During the downward movement of the filter cover, the pomegranate pulp and seeds are pushed aside, allowing the liquid to flow towards the squeezing position. The liquid can enter the interior of the filter cover through the gaps and then be sucked into the hollow tank under negative pressure, which can more fully absorb the liquid and avoid the presence of solids that may affect the liquid absorption effect. At the same time, it effectively prevents pomegranate seeds and pulp from clogging the liquid inlet pipe, ensuring the continuous and stable circulation of raw materials.

[0017] 3. This invention improves fermentation efficiency by injecting nitrogen into the bottom of the raw materials, preventing nitrogen from accumulating on the top of the fermentation tank wall, which would prevent the nitrogen from mixing with the raw materials and affecting the fermentation effect. When the circular plate moves downward, the sealing plug will reseal the sealing ring. By intermittently opening the sealing plug, nitrogen can be injected into the fermentation tank, maintaining the pressure inside the fermentation tank and preventing direct injection from causing the tank pressure to accumulate continuously, which would require the exhaust valve to be opened frequently and affect the fermentation effect.

[0018] 4. In this invention, when the filter cover moves downward, it drives the connecting plate, connecting frame, and scraper downward. The downward movement of the scraper pushes down the liquid splashed on the inner wall of the fermentation tank, allowing the liquid to remix with the raw materials and preventing the liquid from sticking to the inner wall of the fermentation tank, which would affect the mixing effect of the raw materials. When the filter cover moves downward, it drives the short plate and sliding tube downward. When the liquid is sucked in by negative pressure, the sliding tube moves slowly downward to suck in solutions at different levels, preventing the continuous sucking of liquid from one place, which would prevent the liquid at the bottom of the fermentation tank from being sucked in and affect the mixing effect. At the same time, the short rod will rotate against the spiral groove, and the rotation of the spiral groove will drive the sliding tube to rotate. The rotation of the sliding tube and its upward movement will generate disturbance, which can break up the thick pectin and sediment at the bottom, making the raw materials more thoroughly mixed.

[0022] The following is in conjunction with the appendix Figure 1 - Figure 7 This application will be described in further detail.

[0023] This application discloses a fermentation device and fermentation process for producing pomegranate beverages.

[0024] refer to Figure 1 - Figure 7The system includes: a fermenter 1; a support frame 2, which is fixedly installed on the surface of the fermenter 1; a motor 3, which is fixedly installed on the top of the fermenter 1; a feed inlet 4, which is located on the top of the fermenter 1; an air inlet pipe 5, which is located on the top of the fermenter 1, and a nitrogen tank is installed on the top of the air inlet pipe 5; a hollow tube 6 is fixedly installed at the output end of the motor 3, and an agitator blade 7 is fixedly installed on the circumference of the hollow tube 6; a hollow tank 8 is fixedly installed on the inner wall of the fermenter 1, and the hollow tank 8 is rotatably connected to the hollow tube 6; a spiral tube 9 is fixedly installed on the top of the inner wall of the hollow tube 6, and a reciprocating screw 10 is threaded on the inner wall of the spiral tube 9; and the reciprocating screw 10... A sealing plate 11 is fixedly installed at the bottom of the lead screw 10. A hollow column 12 is fixedly installed at the bottom of the sealing plate 11. A circular plate 13 is fixedly installed at the bottom of the hollow column 12. A long rod 14 is fixedly installed on the inner wall of the hollow tank 8. The long rod 14 passes through the circular plate 13. A first-way valve 19 is fixedly installed at the top of the hollow tank 8. An inlet pipe 15 is fixedly installed at the top of the first-way valve 19. During the downward movement of the filter cover 16, the pomegranate pulp and seeds are pushed aside, allowing the liquid to enter the interior of the filter cover 16 through the gaps. Then, it is sucked into the hollow tank 8 under negative pressure, effectively preventing pomegranate seeds and pulp from clogging the inlet pipe 15 and ensuring the continuous and stable circulation of raw materials.

[0025] A filter cover 16 is slidably mounted on the surface of the inlet pipe 15. A slide rod 17 is fixedly mounted on the bottom of the circular plate 13. An L-shaped bracket 18 is fixedly mounted on the surface of the slide rod 17. The end of the L-shaped bracket 18 away from the slide rod 17 is fixedly mounted on the bottom of the filter cover 16. A second check valve 20 is fixedly mounted on the surface of the hollow tube 6. A first check valve 19 is used for liquid inlet and only allows liquid to enter. A second check valve 20 is used for liquid outlet and only allows liquid to be discharged.

[0026] A fermentation process for a fermentation device used in pomegranate beverage production includes the following steps: Step 1: Start motor 3. Motor 3 drives hollow tube 6 and stirring blade 7 to rotate synchronously. The rotation of stirring blade 7 stirs and mixes the raw materials inside fermentation tank 1, improves the contact efficiency between raw materials and bacteria, and promotes uniform fermentation. Step 2: As the hollow tube 6 rotates, it drives the spiral tube 9 to rotate synchronously. The spiral tube 9 drives the reciprocating screw 10, sealing plate 11, hollow column 12 and circular plate 13 to move up and down along the long rod 14. When the circular plate 13 moves downward, a negative pressure is formed inside the hollow tank 8. Under the action of the negative pressure, the raw material liquid at the bottom of the fermenter 1 is drawn in through the first one-way valve 19 and the liquid inlet pipe 15. Step 3: The raw material liquid enters the hollow tank 8 through the first one-way valve 19 and the liquid inlet pipe 15; when the circular plate 13 moves upward, the circular plate 13 squeezes the liquid in the hollow tank 8, and the bottom raw material is discharged upward through the second one-way valve 20. This realizes the bottom-to-top circulation of raw material in the fermentation tank, avoiding long-term accumulation of raw material in the dead corner area at the bottom of the tank, preventing local fermentation abnormalities, and ensuring the overall fermentation consistency. Step 4: When the circular plate 13 moves downward, it simultaneously drives the slide rod 17 and the L-shaped frame 18 to move downward. The L-shaped frame 18 pushes the filter cover 16 downward. During the downward movement of the filter cover 16, the pomegranate pulp and seeds are pushed aside, allowing the liquid to enter the interior of the filter cover 16 through the gaps. Then, it is sucked into the hollow tank 8 under negative pressure, effectively preventing pomegranate seeds and pulp from clogging the liquid inlet pipe 15 and ensuring the continuous and stable circulation of raw materials.

[0027] In this embodiment, during operation: Motor 3 is started, driving the hollow tube 6 and stirring blade 7 to rotate synchronously; the rotating stirring blade 7 stirs and mixes the raw materials inside the fermentation tank 1, improving the contact efficiency between the raw materials and the inoculum, and promoting uniform fermentation. Simultaneously, the rotation of the hollow tube 6 drives the spiral tube 9 to rotate synchronously. The spiral tube 9 drives the reciprocating screw 10, sealing plate 11, hollow column 12, and circular plate 13 to reciprocate up and down along the long rod 14. When the circular plate 13 moves downwards, a negative pressure is formed inside the hollow tank 8. Under this negative pressure, the raw material liquid from the bottom of the fermentation tank 1 is drawn in through the first one-way valve 19 and the inlet pipe 15. The raw material liquid enters the hollow tank 8 through the first one-way valve 19 and the inlet pipe 15. When the circular plate 13 moves downwards... 3. When moving upward, the circular plate 13 squeezes the liquid in the hollow tank 8, and discharges the bottom raw material upward through the second one-way valve 20. This achieves a reciprocating cycle of bottom intake and top discharge of raw material in the fermentation tank, avoiding long-term accumulation of raw material in the dead corner area at the bottom of the tank, preventing local fermentation abnormalities, and ensuring the consistency of overall fermentation. When the circular plate 13 moves downward, it simultaneously drives the slide rod 17 and L-shaped frame 18 to move downward. The L-shaped frame 18 pushes the filter cover 16 downward. During the downward movement of the filter cover 16, the pomegranate pulp and seeds are pushed aside, allowing the liquid to enter the interior of the filter cover 16 through the gaps, and then be sucked into the hollow tank 8 under negative pressure. This effectively prevents pomegranate seeds and pulp from clogging the liquid inlet pipe 15 and ensures the continuous and stable circulation of raw materials.

[0028] Please see Figure 1 - Figure 7Based on the above embodiments, in another embodiment of the present invention, the fermenter 1 is provided with an exhaust device and a regulating device to prevent gas accumulation. The exhaust device includes an air inlet 211, an air inlet groove 212, and a third one-way valve 213. The air inlet 211 is fixedly installed on the surface of the hollow tube 6, and a first one-way air inlet valve is provided inside the air inlet 211. The air inlet groove 212 is opened on the surface of the spiral tube 9, and a second one-way air inlet valve is provided inside the air inlet groove 212. The third one-way valve 213 is located at the bottom of the hollow tank 8 and is used for gas discharge. Injecting nitrogen into the bottom of the raw material helps to improve fermentation efficiency and prevents all nitrogen from accumulating on the top of the inner wall of the fermenter 1, which would prevent the nitrogen from being repeatedly mixed with the raw material for fermentation and affect the fermentation effect.

[0029] A sliding rod 214 slides through the surface of the hollow tube 6. A ring 215 is fixedly installed on the top of the sliding rod 214. A sealing ring 217 is fixedly installed on the inner wall of the air inlet pipe 5. An L-shaped rod 216 slides through the surface of the sealing ring 217. A sealing plug 218 is fixedly installed on the top of the L-shaped rod 216. By intermittently opening the sealing plug 218, nitrogen gas is injected into the fermenter 1 from the nitrogen tank. This maintains the pressure inside the fermenter 1 and prevents the pressure from accumulating continuously due to direct injection, which would require frequent opening of the exhaust valve and affect the fermentation effect.

[0030] A first spring is installed between the hollow tube 6 and the sliding rod 214. The sliding rod 214 is reset by the elastic force of the first spring. A second spring is installed between the sealing ring 217 and the L-shaped rod 216. The L-shaped rod 216 is reset by the elastic force of the second spring.

[0031] In this embodiment, during operation: the sealing plate 11 moves downward to create negative pressure. This negative pressure causes nitrogen gas at the top of fermenter 1 to enter the hollow tube 6 through the air inlet 211 and the first one-way air inlet valve. When the sealing plate 11 moves upward, it compresses the gas inside the hollow tube 6, allowing it to enter the air inlet slot 212 through the second one-way air inlet valve. The gas then flows along the spiral tube 9 and the hollow column 12 into the hollow tank 8. Finally, the nitrogen gas is discharged through the third one-way valve 213. Injecting nitrogen gas into the bottom of the raw material helps improve fermentation efficiency and prevents nitrogen gas from accumulating on the top of the inner wall of fermenter 1, which would prevent the nitrogen gas from mixing with the raw material and affecting the fermentation effect. At the same time, the downward movement of the sealing plate 11 pushes the sliding... When rod 214 moves upward, the upward movement of sliding rod 214 will drive ring 215 to move upward. The upward movement of ring 215 will push L-shaped rod 216 to move upward. The upward movement of L-shaped rod 216 will drive sealing plug 218 to move upward. The upward movement of sealing plug 218 will disengage from sealing ring 217, allowing nitrogen to enter fermenter 1. When circular plate 13 moves downward, sealing plug 218 will reseal sealing ring 217. By intermittently opening sealing plug 218, nitrogen can be injected into fermenter 1 from nitrogen tank, which can maintain the pressure inside fermenter 1 and prevent direct injection from causing continuous pressure accumulation in the tank, which would require frequent opening of the exhaust valve and affect the fermentation effect.

[0032] The adjusting device includes a connecting plate 221, a connecting frame 222, and a scraper 223. The connecting plate 221 is fixedly installed on the circumferential surface of the filter cover 16, the connecting frame 222 is fixedly installed on the surface of the connecting plate 221, and the scraper 223 is fixedly installed on the top of the connecting frame 222. When the filter cover 16 moves downward, the connecting plate 221, the connecting frame 222, and the scraper 223 also move downward. The downward movement of the scraper 223 pushes down the liquid splashed on the inner wall of the fermenter 1, allowing the liquid to remix with the raw materials and preventing the liquid from sticking to the inner wall of the fermenter 1 and affecting the mixing effect of the raw materials.

[0033] A connecting rod 224 is fixedly installed on the top of the inner wall of the inlet pipe 15. A short plate 225 is slidably installed on the inner wall of the filter cover 16. A sliding tube 226 is fixedly installed on the surface of the short plate 225. A spiral groove 228 is opened on the inner wall of the sliding tube 226. A short rod 227 is fixedly installed at the bottom of the connecting rod 224. By rotating and moving upward through the sliding tube 226, the self-rotation generates disturbance that can break up the thick pectin and sediment at the bottom, so that the raw materials are mixed more thoroughly.

[0034] The short rod 227 slides on the inner wall of the spiral groove 228, and the scraper 223 contacts the inner wall of the fermenter 1, scraping the inside of the fermenter 1 through the scraper 223.

[0035] The upward movement of the filter cover 16 causes the connecting plate 221, connecting frame 222, and scraper 223 to move upward as well. Simultaneously, liquid discharged from the second one-way valve 20 may splash onto the inner wall of the fermenter 1. When the filter cover 16 moves downward, the connecting plate 221, connecting frame 222, and scraper 223 also move downward. The downward movement of the scraper 223 pushes down the liquid splashed onto the inner wall of the fermenter 1, allowing the liquid to remix with the raw materials and preventing the liquid from sticking to the inner wall of the fermenter 1, thus affecting the mixing effect. At the same time, the downward movement of the filter cover 16 causes the short plate 225 and sliding tube 226 to move downward, drawing in liquid through negative pressure. When the liquid is in the liquid stage, the sliding tube 226 moves slowly downward to draw in solutions at different levels, preventing the continuous drawing of liquid from one place and thus preventing the liquid at the bottom of the fermenter 1 from being drawn in, which would affect the mixing effect. At the same time, the downward movement of the sliding tube 226 will drive the spiral groove 228 to move upward. The upward movement of the spiral groove 228 will bring it into contact with the short rod 227, which will rotate against the spiral groove 228. The rotation of the spiral groove 228 will drive the sliding tube 226 to rotate. The rotation and upward movement of the sliding tube 226 will generate disturbance that can break up the thick pectin and sediment at the bottom, making the raw materials more thoroughly mixed.

The connecting plate (221) is fixedly installed on the circumferential surface of the filter cover (16), the connecting frame (222) is fixedly installed on the surface of the connecting plate (221), and the scraper (223) is fixedly installed on the top of the connecting frame (222).

7. A fermentation apparatus for pomegranate beverage production according to claim 6, characterized in that, A connecting rod (224) is fixedly installed on the top of the inner wall of the liquid inlet pipe (15), a short plate (225) is slidably installed on the inner wall of the filter cover (16), a sliding tube (226) is fixedly installed on the surface of the short plate (225), a spiral groove (228) is opened on the inner wall of the sliding tube (226), and a short rod (227) is fixedly installed at the bottom of the connecting rod (224).

8. A fermentation apparatus for pomegranate beverage production according to claim 7, characterized in that, The short rod (227) slides on the inner wall of the spiral groove (228), and the scraper (223) contacts the inner wall of the fermenter (1).

9. A fermentation process for a fermentation apparatus for producing pomegranate beverages, using the fermentation apparatus for producing pomegranate beverages as described in claim 8, characterized in that, Includes the following steps: Step 1: Start the motor (3). The motor (3) drives the hollow tube (6) and the stirring blade (7) to rotate synchronously. The stirring blade (7) rotates to stir and mix the raw materials inside the fermentation tank (1), improves the contact efficiency between the raw materials and the bacteria, and promotes uniform fermentation. Step 2: As the hollow tube (6) rotates, it drives the spiral tube (9) to rotate synchronously. The spiral tube (9) drives the reciprocating screw (10), sealing plate (11), hollow column (12) and circular plate (13) to move up and down along the long rod (14). When the circular plate (13) moves downward, a negative pressure is formed inside the hollow tank (8). Under the action of the negative pressure, the raw material liquid at the bottom of the fermenter (1) is drawn in through the first one-way valve (19) and the liquid inlet pipe (15). Step 3: The raw material liquid enters the hollow tank (8) through the first one-way valve (19) and the liquid inlet pipe (15); when the circular plate (13) moves upward, the circular plate (13) squeezes the liquid in the hollow tank (8) and discharges the raw material from the bottom upward through the second one-way valve (20). This achieves the bottom-to-top circulation of raw material in the fermentation tank, which avoids long-term deposition of raw material in the dead corner area at the bottom of the tank, prevents local fermentation abnormalities, and ensures the overall fermentation consistency. Step 4: When the circular plate (13) moves downward, it simultaneously drives the slide bar (17) and the L-shaped frame (18) to move downward. The L-shaped frame (18) pushes the filter cover (16) downward. During the downward movement of the filter cover (16), the pomegranate pulp and seeds are pushed away to the sides, so that the liquid can enter the filter cover (16) through the gap and then be sucked into the hollow tank (8) under negative pressure. This effectively avoids the pomegranate seeds and pulp clogging the liquid inlet pipe (15) and ensures that the raw material circulation continues stably.
