Description

Technical Field

[0001] The present invention relates to the technical field of enzyme fermentation, in particular to a fermentation process for producing enzyme food. Background Art

[0002] Enzymes, also known as enzymes, are biologically active substances composed of amino acids and found in all living plants and animals. Enzyme ingredients include various nutrients provided by plant materials and microorganisms, functional plant chemical components from natural plants, and some physiologically active substances produced by fermentation, including vitamins, amino acids, polysaccharides, peptides, polyphenols, flavonoids, mineral elements, and organic acids. The enzyme concentrates or enzyme beverages currently on the market are products made by fermenting various fruits or plants for a long time. Fruits, plants, grains, meats, etc. can all be fermented. Traditional fermented products include yogurt, natto, fermented black beans, and kimchi.

[0003] During enzyme fermentation, the raw materials need to be stirred. This promotes thorough mixing, accelerates the fermentation process, and prevents deterioration of the unsoaked top layer of raw materials. Stirring also helps create a more uniform fermentation environment. After fermentation, solid residues are removed through filtration and centrifugation to obtain a clarified fermentation broth.

[0004] In the existing enzyme fermentation process, a stirring rod is generally used to stir the raw materials. The stirring method of the stirring rod can only mix the raw materials as evenly as possible, and the fermentation of the raw materials is carried out from the outside to the inside. For large raw materials, it is difficult to release the internal fermentable components in time even if they are stirred, and the fermentation time cannot be effectively shortened. After the fermentation of the raw materials is completed, after filtering, centrifuging, etc. to remove the enzyme residue, some fermentable substances in the enzyme residue will still be mixed into the fermentation liquid during filtration and centrifugation. The existing filtration method generally introduces the feed liquid into a new device for filtration. This filtration method will destroy the original fermentation environment, resulting in the fermentation liquid produced by the fermentable substances mixed into the fermentation liquid being unable to undergo secondary fermentation, resulting in the produced fermentation liquid being of low quality. To this end, we propose an enzyme food production and fermentation process. Summary of the Invention

[0005] The purpose of the present invention is to provide an enzyme food production fermentation process that can effectively solve the problems raised in the background technology.

[0006] To solve the above technical problems, the present invention is achieved through the following technical solutions: The present invention is a fermentation process for producing enzyme food, which uses an enzyme device for fermentation. The enzyme device includes a sealed fermentation tank body, a processing component, a filtering component, and a discharge component, and specifically includes the following steps: S1. Add crushed fermentation raw materials and bacterial liquid for raw material fermentation into the fermentation tank; S2. Use processing components to crush and stir the fermenting raw materials: The processing assembly includes a vertical tube and a spiral rod arranged in the middle of the fermentation tank body, and a crushing spike arranged on the spiral leaf of the spiral rod. The middle and upper section of the vertical tube is provided with a liquid permeable hole, and the middle and upper section of the spiral leaf of the spiral rod is provided with a leakage hole. The spiral rod is used to transport the liquid at the bottom of the fermentation tank body upward through the vertical tube to stir the liquid. The crushing spikes crush the raw materials to release fermentable components. The crushing spikes scratch the bubble film on the surface of the raw materials to release gas. Part of the liquid transported in the vertical tube is discharged through the liquid permeable hole to reduce the amount of liquid discharged from the top of the vertical tube. The liquid on the spiral leaf of the spiral rod passes through the leakage hole to slow down the rising speed of the liquid in the vertical tube. S3. After the primary fermentation is completed, the enzyme residue is separated using a filter assembly, and the enzyme residue is discharged using a discharge assembly to obtain a fermentation liquid; the filter assembly includes a filter screen; when in use, the filter screen is moved above the vertical pipe, and the screw rod transports the feed liquid to the filter screen to filter out the enzyme residue, and the screw rod continues to transport the enzyme residue to the discharge assembly to be discharged from the fermentation tank; S4. Continue fermenting the fermentation liquid in the fermentation tank for one month to obtain the enzyme stock solution.

[0007] Preferably, the processing assembly further comprises a spiral baffle, a plurality of spiral baffles are evenly spaced on the spiral blade surface of the spiral rod, the crushing spikes are fixedly mounted above the spiral baffles, and the crushing spikes are evenly spaced above the spiral baffles; In S2, the spiral baffle raises the height of the crushing spikes on the spiral blade surface of the spiral rod. During the process of the spiral rod conveying the liquid, the spiral baffle blocks the large raw materials on the surface of the spiral rod, so that the crushing spikes contact the large raw materials above the spiral baffle and crush the large raw materials.

[0008] Preferably, the spiral baffle is fixedly arranged at the middle and lower section of the spiral blade surface of the spiral rod, the leakage hole is located at the middle and upper section of the spiral blade of the spiral rod, the lowermost liquid permeable hole and the lowermost leakage hole are at the same height, and the height of the fermentation raw materials and bacterial liquid added into the fermentation tank body is lower than the height of the uppermost liquid permeable hole; In S2, under the conveying action of the spiral rod, part of the liquid is discharged from the liquid permeable hole and enters the upper middle part of the fermentation tank body, and the remaining liquid and raw materials are discharged from the upper opening of the vertical pipe into the upper part of the fermentation tank body, so that the raw materials and liquid are dispersed. The liquid at the bottom of the fermentation tank body is conveyed into the vertical pipe by the spiral rod, and the liquid deposited at the bottom of the fermentation tank body is conveyed to the upper part of the fermentation tank body, forming a circular agitation. The gas generated by the agitation rises in the liquid. As the liquid is discharged from the vertical pipe through the liquid permeable hole, the raw materials near the outside of the vertical pipe are displaced by the liquid discharged from the vertical pipe. The gas discharged from the liquid permeable hole rises rapidly from the liquid and is discharged into the upper part of the fermentation tank body.

[0009] Preferably, two sets of filter assemblies are provided on the fermentation tank body, and the filter assemblies further include a hydraulic assembly and a connecting frame, wherein the hydraulic assembly is fixedly provided on the outside of the upper end of the fermentation tank body, and the output end of the hydraulic assembly penetrates the tank wall of the fermentation tank body and extends into the interior of the fermentation tank body, the connecting frame is provided inside the fermentation tank body and fixedly connected to the output end of the hydraulic assembly, and the filter screen is fixedly mounted on the side of the connecting frame; In S3, after one fermentation is completed, two hydraulic components are used to push the connecting frame and the filter screen, so that the two connecting frames are stuck in the upper opening of the vertical pipe, and the two filter screens are just above the vertical pipe. When the screw rod transports the slurry into the two filter screens, the liquid in the slurry passes through the mesh of the filter screen, and the height of the slurry entering the filter screen is higher than the liquid level of the slurry outside the vertical pipe. The liquid in the slurry transported by the screw rod in the filter screen flows downward through the leakage hole, slowing down the speed of the liquid transporting upward, and the liquid flowing downward flows outward on the spiral blades of the screw rod due to centrifugal action. When the slurry passes through the filter screen, all the liquid in the slurry passes through the mesh of the filter screen and is filtered out. The remaining enzyme residue is continued to be transported upward to the discharge component and discharged from the fermentation tank body, completing the filtration of the enzyme residue.

[0010] Preferably, the discharge assembly includes a collecting box fixedly arranged above the fermentation tank body, a discharge pipe fixedly arranged on one side of the collecting box, and a suction pump fixedly arranged at the discharge end at the bottom of the discharge pipe. The collecting box is connected to the interior of the fermentation tank body, and the enzyme residue transported by the screw rod enters the collecting box; In S3, the suction pump draws away the enzyme residue in the collection box through the discharge pipe, completing the discharge of the enzyme residue.

[0011] Preferably, an air pressure detector is fixedly installed inside the fermentation tank; In S2, when it is detected that the gas pressure value in the fermentation tank body exceeds a threshold value, the suction pump discharges excess gas in the fermentation tank body through the discharge pipe and the collection box.

[0012] Preferably, the processing assembly further comprises a power assembly for driving the screw to rotate, the power assembly is fixedly arranged below the fermentation tank body, and an observation window is provided on the upper side of the fermentation tank body; In S2, the screw is driven to rotate by the power assembly. When the liquid is processed, the specific situation of the liquid being stirred outside the vertical pipe is observed through the observation window. If the liquid is stirred violently, the power of the power assembly is reduced.

[0013] Preferably, a feed inlet is provided on the upper side of the fermentation tank body; In S1, fermentation raw materials and bacterial liquid are added to the fermentation tank through the feed port, and the feed port is closed after the addition is completed.

[0014] Preferably, a liquid outlet valve is provided on one side of the lower end of the fermentation tank body; In S4, after the fermentation of the enzyme stock solution is completed, the liquid outlet valve is opened to discharge the enzyme stock solution from the fermentation tank through the liquid outlet valve.

[0015] The present invention has the following beneficial effects: 1. The present invention uses crushing spikes to crush the raw materials during the fermentation process, which can release the fermentable components within the raw materials, effectively increasing the fermentation speed of the raw materials. By breaking up the raw materials, the surface area of ​​the raw materials in contact with the liquid can be significantly increased, allowing for more complete contact between the microorganisms or enzymes in the liquid and the raw materials, thereby accelerating the chemical reaction rate and shortening the fermentation time. By stirring and crushing the raw materials during the fermentation process, the problem of excessively high or low local concentrations of components can be avoided, ensuring the consistency of fermentation conditions.

[0016] 2. The present invention can effectively eliminate bubbles attached to the surface of the raw materials by crushing the raw materials and breaking up the potholes and gaps on the surface of the raw materials.

[0017] 3. The present invention utilizes a liquid permeable hole to reduce the amount of liquid discharged from the upper portion of the vertical tube, thereby reducing the flow rate of liquid discharged from the upper outlet of the vertical tube. This prevents liquid discharged from the vertical tube from colliding with liquid outside the vertical tube, causing significant disturbance and foaming of the external liquid, thereby preventing the balance and stability of the external liquid from being disrupted. By utilizing the liquid leakage hole to direct liquid above the spiral blades to below the spiral blades, the spiral rod can discharge more liquid through the liquid permeable hole.

[0018] 4. The present invention utilizes the openings of the liquid-permeable and liquid-leaking holes to break up the surface of the raw material, further breaking up the raw material and promoting contact between the microorganisms or enzymes in the liquid and the raw material. The spiral rod conveys the raw material multiple times, scraping off the surface layer by layer, thereby increasing the fermentation time.

[0019] 5. The present invention uses a filter to filter the liquid after the first fermentation is completed. By centrifugation, the fermentable components in the enzyme residue can be separated. After filtration, these components re-enter the fermentation tank body with the liquid, and these fermentable components can be fermented again in the fermentation tank body. During the secondary fermentation, these fermentable components can be removed, so that the final enzyme stock solution is of higher quality. By filtering out the enzyme residue in the fermentation tank body, the entry of external bacteria can be prevented. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention. Example:

[0024] See also Figures 1-7 As shown, an enzyme food production fermentation process uses an enzyme device for fermentation, the enzyme device includes a closed fermentation tank body 1, a processing component 3 and a filtering component 4, and a discharge component 5, and specifically includes the following steps: S1. Add crushed fermentation raw materials and bacterial liquid for raw material fermentation into the fermentation tank body 1; the fermentation raw materials are selected from fresh fruits, vegetables and natural plant materials of herbs that are not rotten or odorous. After the raw materials are cleaned and dried to remove surface moisture, they are crushed, sliced, cut into pieces, or pulped and enzymatically hydrolyzed. Then, sugar substances are added as needed, and the selected raw materials are added to the fermentation tank body 1 for fermentation.

[0025] S2. Use processing component 3 to crush and stir the fermented raw materials: The processing assembly 3 includes a vertical tube 31 fixedly arranged at the middle part of the inner side of the fermentation tank body 1, a spiral rod 32 movably arranged inside the vertical tube 31, and a crushing spike 33 fixedly arranged on the surface of the spiral blade in the spiral rod 32. The middle and upper part of the vertical tube 31 is provided with a liquid permeable hole 2, and the middle and upper part of the spiral blade of the spiral rod 32 is provided with a leakage hole 6. The spiral rod 32 is used to transport the liquid at the bottom of the fermentation tank body 1 upward through the vertical tube 31 to stir the liquid. The crushing spike 33 crushes the raw material to release fermentable components. The crushing spike 33 cuts the bubble film on the surface of the raw material to release gas. Part of the liquid transported in the vertical tube 31 is discharged through the liquid permeable hole 2 to reduce the amount of liquid discharged from the top of the vertical tube 31. The liquid on the spiral blade of the spiral rod 32 passes through the leakage hole 6 to slow down the rising speed of the liquid in the vertical tube 31. Based on this step, by using the crushing spikes 33 to crush the raw materials during the fermentation process, the fermentable components inside the raw materials can be released, which can effectively increase the fermentation speed of the raw materials. By crushing the raw materials, the surface area of ​​the raw materials in contact with the liquid can be significantly increased, so that the contact between the microorganisms or enzymes in the liquid and the raw materials is more complete, thereby accelerating the chemical reaction rate and shortening the fermentation time. After fermentation reaches a certain level, it is easy to have the problem of local component concentration being too high or too low. By stirring and crushing the raw materials during the fermentation process, the problem of local component concentration being too high or too low can be avoided, ensuring the consistency of the fermentation conditions.

[0026] Based on this step, since gas is generated during the fermentation process, it easily adheres to the surface of the raw materials and above the liquid, forming a bubble film. These bubble films not only hinder the contact between oxygen and microorganisms, affecting respiration and metabolic efficiency, and reducing fermentation speed, but also interfere with mass and heat transfer efficiency, reducing production capacity. During the fermentation process, irregular pits will form on the surface of the raw materials. Once bubbles are generated in these pits, they are not easily stirred by traditional stirring methods using a stirring rod. This process can effectively eliminate bubbles attached to the raw material surface by breaking up the pits and gaps on the raw material surface.

[0027] This step utilizes liquid permeation holes 2 to reduce the amount of liquid discharged from the top of vertical tube 31, thereby reducing the flow rate of liquid discharged from the top outlet of vertical tube 31. This prevents liquid discharged from vertical tube 31 from colliding with the liquid outside of vertical tube 31, significantly disturbing the liquid outside and causing a large amount of foam, thereby preventing the balance and stability of the liquid outside from being disrupted. Liquid leak holes 6 are used to direct liquid above the spiral lobes of screw 32 to below the spiral lobes, allowing screw 32 to discharge more liquid through liquid permeation holes 2.

[0028] In this step, the openings of the liquid permeable holes 2 and the liquid leakage holes 6 are used to break up the surface of the raw material. As the raw material passes through the openings of the liquid permeable holes 2 and the liquid leakage holes 6, friction with the openings of the liquid permeable holes 2 and the liquid leakage holes 6 not only scrapes away and removes bubbles from the raw material, but also breaks up the surface of the raw material, further breaking up the raw material and promoting contact between microorganisms or enzymes in the liquid and the raw material. Multiple conveyances of the raw material by the screw 32 can scrape the surface of the raw material layer by layer, thereby increasing the fermentation time.

[0029] S3. After the primary fermentation is completed, the enzyme residue is separated by the filter assembly 4, and the enzyme residue is discharged by the discharge assembly 5 to obtain the fermentation liquid; the filter assembly 4 includes a filter screen 41; when in use, the filter screen 41 is moved above the vertical pipe 31, and the screw rod 32 transports the liquid to the filter screen 41 to filter out the enzyme residue, and the screw rod 32 continues to transport the enzyme residue to the discharge assembly 5 to be discharged from the fermentation tank body 1; Based on this step, after one fermentation is completed, the feed liquid is filtered using a filter 41 to separate the enzyme residue. During the filtering process, the fermentable components in the enzyme residue can be separated by centrifugation. After filtration, these components re-enter the fermentation tank body 1 along with the liquid, enabling these fermentable components to undergo secondary fermentation in the fermentation tank body. During the secondary fermentation, these fermentable components can be removed, so that the final enzyme stock solution has higher quality. In this step, by filtering out the enzyme residue in the fermentation tank body 1, the entry of external bacteria can be avoided. The existing filtering method is to introduce the feed liquid into a new device for filtration. This filtering method will destroy the original fermentation environment, causing the filtered fermentation liquid to be unable to undergo secondary fermentation, resulting in the fermentation liquid produced being of low quality.

[0030] S4. Continue fermenting the fermentation liquid in the fermentation tank 1 for one month to obtain the enzyme stock solution.

[0031] The processing assembly 3 further includes a spiral baffle 34. A plurality of spiral baffles 34 are evenly spaced on the spiral blade surface of the spiral rod 32. The crushing spikes 33 are fixedly mounted above the spiral baffles 34. The crushing spikes 33 are evenly spaced above the spiral baffles 34. In S2, the spiral baffle 34 raises the height of the crushing spike 33 on the spiral blade surface of the spiral rod 32. During the process of the spiral rod 32 conveying the liquid, the spiral baffle 34 blocks the large raw materials on the surface of the spiral rod 32, so that the crushing spike 33 contacts the large raw materials above the spiral baffle 34 and crushes the large raw materials.

[0032] If the crushing spikes 33 are too long, they will block the raw materials in the liquid. If they are too short, they will not be able to crush the raw materials in the liquid. The length of the crushing spikes 33 ranges from 5mm to 1cm. The spiral baffles 34 are used to increase the distance between the crushing spikes 33 and the spiral blade surface of the spiral rod 32, allowing the crushing spikes 33 to contact the raw materials at a higher position on the spiral blade surface of the spiral rod 32, thereby crushing more raw materials. The spiral baffles 34 hinder the raw materials, preventing them from being directed towards the inner wall of the vertical tube 31 during the raw material conveying process, making them more easily crushed by the crushing spikes 33.

[0033] The spiral retaining bar 34 is fixedly mounted on the lower middle section of the spiral blade surface of the spiral rod 32. The leakage hole 6 is located on the upper middle section of the spiral blade of the spiral rod 32. The lowest permeable hole 2 and the lowest leakage hole 6 are at the same height. The height of the fermentation raw materials and bacterial liquid added to the fermentation tank body 1 is lower than the height of the highest permeable hole 2. In S2, under the conveying action of the screw rod 32, part of the liquid is discharged from the liquid permeable hole 2 and enters the upper middle part of the fermentation tank body 1, and the remaining liquid and raw materials are discharged from the upper opening of the vertical pipe 31 into the upper part of the fermentation tank body 1, so that the raw materials and liquid are dispersed. The liquid at the bottom of the fermentation tank body 1 is conveyed into the vertical pipe 31 by the screw rod 32, and the liquid deposited at the bottom of the fermentation tank body 1 is conveyed to the upper part of the fermentation tank body 1, forming a circular agitation. The gas generated by the agitation rises in the liquid. As the liquid is discharged from the vertical pipe 31 through the liquid permeable hole 2, the raw materials near the outside of the vertical pipe 31 are displaced by the liquid discharged from the vertical pipe 31, and the gas discharged from the liquid permeable hole 2 rises rapidly from the liquid and is discharged into the upper part of the fermentation tank body 1.

[0034] Based on this step, during the rotation of the screw 32, by discharging the liquid in the upper middle portion of the vertical tube 31 out of the vertical tube 31, the screw 32 can draw the raw materials deposited at the bottom of the fermentation tank 1 into the vertical tube 31, thereby preventing the raw materials from depositing and agglomerating at the bottom of the fermentation tank 1. This also allows the gas discharged from the liquid permeable hole 2 to easily rise in the liquid outside the vertical tube 31 and discharge the liquid.

[0035] Among them, two groups of filter assemblies 4 are set on the fermentation tank body 1. The filter assembly 4 also includes a hydraulic assembly 42 and a connecting frame 43. The hydraulic assembly 42 is fixedly arranged on the outside of the upper end of the fermentation tank body 1. The output end of the hydraulic assembly 42 passes through the tank wall of the fermentation tank body 1 and extends into the interior of the fermentation tank body 1. The connecting frame 43 is arranged inside the fermentation tank body 1 and is fixedly connected to the output end of the hydraulic assembly 42. The filter screen 41 is fixedly mounted on the side of the connecting frame 43; In S3, after one fermentation is completed, two hydraulic components 42 are used to push the connecting frame 43 and the filter 41, so that the two connecting frames 43 are stuck in the upper opening of the vertical pipe 31, and the two filter screens 41 are just above the vertical pipe 31. When the screw rod 32 transports the feed into the two filter screens 41, the liquid in the feed passes through the mesh of the filter screen 41, and the height of the feed entering the filter screen 41 is higher than the liquid level of the feed outside the vertical pipe 31. The liquid in the feed transported by the screw rod 32 in the filter screen 41 flows downward through the leakage hole 6, slowing down the speed of the liquid transporting upward. The downward flowing liquid flows outward on the spiral leaves of the screw rod 32 due to centrifugal action. When the feed passes through the filter screen 41, all the liquid in the feed passes through the mesh of the filter screen 41 and is filtered out. The remaining enzyme residue is continued to be transported upward to the discharge component 5 and discharged from the fermentation tank body 1, completing the filtration of the enzyme residue.

[0036] Based on this step, the screw rod 32 continuously transports the enzyme residue, and the enzyme residue is constantly rubbed against the leakage hole 6 and the mesh of the filter screen 41, which can separate the fermentable substances in the enzyme residue. The filtered enzyme residue is promptly discharged by the discharge component 5, which can avoid the accumulation of enzyme residue at the mesh of the filter screen 41, and can ensure that the filter screen 41 always has a high filtering capacity for the enzyme residue and improve the filtering efficiency. The screw rod 32 continuously transports the enzyme residue, plays the role of centrifugal filtration on the feed liquid, can throw out the fermentable substances in the enzyme residue, so that the enzyme residue can be fully utilized.

[0037] The discharge assembly 5 includes a collecting box 51 fixedly mounted above the fermentation tank 1, a discharge pipe 52 fixedly mounted on one side of the collecting box 51, and a suction pump 53 fixedly mounted at the discharge end of the bottom of the discharge pipe 52. The collecting box 51 is connected to the interior of the fermentation tank 1, and the enzyme residue transported by the screw 32 enters the collecting box 51. In S3, the suction pump 53 draws away the enzyme residue in the collection box 51 through the discharge pipe 52, completing the discharge of the enzyme residue.

[0038] Based on this step, an electrically controlled valve is installed at the connection between the collection box 51 and the internal part of the fermentation tank body 1. When the enzyme residue does not need to be discharged, the electrically controlled valve is closed to prevent bacteria from entering the device. An air inlet valve connected to the outside world is provided in the collection box 51. When the suction pump 53 is working, the outside air enters the collection box 51 to form an airflow that blows the enzyme residue into the discharge pipe 52.

[0039] Among them, an air pressure detector is fixedly installed inside the fermentation tank body 1; In S2 , when it is detected that the gas pressure value in the fermentation tank body 1 exceeds a threshold value, the suction pump 53 discharges excess gas in the fermentation tank body 1 through the discharge pipe 52 and the collection box 51 .

[0040] The processing assembly 3 further includes a power assembly 35 for driving the screw rod 32 to rotate. The power assembly 35 is fixedly arranged below the fermentation tank body 1. An observation window 7 is provided on the upper side of the fermentation tank body 1. In S2 , the screw rod 32 is driven to rotate by the power assembly 35 . When the liquid is processed, the specific situation of the liquid being stirred outside the vertical pipe 31 is observed through the observation window 7 . If the liquid is stirred violently, the power of the power assembly 35 is reduced.

[0041] Among them, a feed inlet 8 is provided on the upper side of the fermentation tank body 1; In S1 , fermentation raw materials and bacterial liquid are added to the fermentation tank body 1 through the feed port 8 , and the feed port 8 is closed after the addition is completed.

[0042] Among them, a liquid outlet valve 9 is provided on one side of the lower end of the fermentation tank body 1; In S4 , after the fermentation of the enzyme stock solution is completed, the liquid outlet valve 9 is opened to discharge the enzyme stock solution from the fermentation tank body 1 through the liquid outlet valve 9 .

The fermentation process for producing an enzyme food according to claim 2, characterized in that: The spiral retaining bar (34) is fixedly arranged on the middle and lower section of the spiral blade surface of the spiral rod (32), the leakage hole (6) is located on the middle and upper section of the spiral blade of the spiral rod (32), the lowermost permeable hole (2) and the lowermost leakage hole (6) are at the same height, and the height of the fermentation raw materials and bacterial liquid added into the fermentation tank body (1) is lower than the height of the uppermost permeable hole (2); In S2, under the conveying action of the screw rod (32), part of the liquid is discharged from the liquid permeable hole (2) and enters the upper middle part of the fermentation tank body (1), and the remaining liquid and raw materials are discharged from the upper opening of the vertical pipe (31) and enter the upper middle part of the fermentation tank body (1), so that the raw materials and liquid are dispersed. The liquid at the bottom of the fermentation tank body (1) is conveyed into the vertical pipe (31) by the screw rod (32), and the liquid deposited at the bottom of the fermentation tank body (1) is conveyed to the upper part of the fermentation tank body (1), forming a circulating agitation. The gas generated by the agitation rises in the liquid. As the liquid is discharged from the vertical pipe (31) through the liquid permeable hole (2), the raw materials near the outside of the vertical pipe (31) are displaced by the liquid discharged from the vertical pipe (31). The gas discharged from the liquid permeable hole (2) rises rapidly from the liquid and is discharged into the upper part of the fermentation tank body (1).

4. The fermentation process for producing an enzyme food according to claim 1, characterized in that: Two groups of filter assemblies (4) are provided on the fermentation tank body (1), and the filter assembly (4) further includes a hydraulic assembly (42) and a connecting frame (43). The hydraulic assembly (42) is fixedly provided on the outside of the upper end of the fermentation tank body (1), and the output end of the hydraulic assembly (42) penetrates the tank wall of the fermentation tank body (1) and extends into the interior of the fermentation tank body (1).

The filter screen (41) is fixedly installed on the side of the connecting frame (43); In S3, after one fermentation is completed, two hydraulic components (42) are used to push the connecting frame (43) and the filter (41), so that the two connecting frames (43) are stuck at the upper opening of the vertical pipe (31), and the two filter screens (41) are just above the vertical pipe (31). When the screw rod (32) transports the liquid into the two filter screens (41), the liquid in the liquid passes through the mesh of the filter screen (41), and the height of the liquid entering the filter screen (41) is higher than the liquid outside the vertical pipe (31). The liquid in the feed liquid transported by the screw rod (32) in the filter (41) flows downward through the leakage hole (6), slowing down the speed of the liquid transported upward. The liquid flowing downward flows outward on the spiral blades of the screw rod (32) due to the centrifugal effect. When the feed liquid passes through the filter (41), all the liquid in the feed liquid is filtered out through the mesh of the filter (41), and the remaining enzyme residue is continued to be transported upward to the discharge component (5) and discharged from the fermentation tank body (1), completing the filtration of the enzyme residue.
