Description

Technical Field

[0001] This invention relates to the field of fermentation equipment for food and medicine homology, and in particular to a fermentation device for intelligent quantitative supply of food and medicine homology and its usage method. Background Technology

[0002] Foods that combine nutritional value with medicinal benefits, and are compound food-medicine homologous foods prepared using microbial fermentation technology, can effectively extract active nutrients from raw materials and improve the absorption rate of food. They have become a research and production hotspot in the health food industry. In actual industrial-scale fermentation production, the precision of material supply, sealing performance, material mixing effect, and oxygen regulation capacity of the fermentation device directly determine the quality of the fermented product.

[0003] Currently, traditional food and medicinal homology fermentation devices on the market still have many technical shortcomings: First, most fermentation devices only have a single feeding structure, which cannot classify and store solid and liquid food and medicinal homology fermentation materials in different forms and independently feed them in proportion. It is difficult to control the accuracy of material proportioning, which can easily cause imbalance of fermentation substrate and reduce the quality of finished product. Second, the conventional silo cover sealing structure is simple and mostly adopts a single-layer sealing structure, which has poor sealing and protection performance. The fermentation materials are easily affected by moisture and contamination by external bacteria, and are also prone to material volatilization loss. Third, traditional feeding structures cannot achieve precise feeding. Precise and quantitative feeding is problematic because outside air can easily mix in during the feeding process, making highly active food and medicinal materials prone to oxidation and deterioration. Furthermore, backflow of materials can affect the sterile environment inside the fermenter. Fourth, existing stirring structures are mostly single-rotation stirring modes, only capable of revolution stirring, resulting in large stirring blind spots, poor material mixing uniformity, and an inability to adapt to the fermentation needs of complex food and medicinal materials. Fifth, conventional fermentation equipment features a fixed gas injection structure, making it impossible to achieve differentiated oxygen control in different areas of the tank, and difficult to simultaneously adapt to anaerobic, aerobic, and facultative anaerobic fermentation processes, resulting in low equipment versatility. Summary of the Invention

[0004] The purpose of this invention is to provide an intelligent, quantitative fermentation device for food and medicine homology and its usage method, which enables independent storage of solid and liquid materials, precise quantitative anaerobic feeding, full-area stirring without blind spots, and differentiated oxygen control by region, adapting to various fermentation processes and improving the quality and production efficiency of fermented food and medicine homology products.

[0009] Preferably, the stirring unit includes a stirring motor fixed to the top of the fermentation tank, the output shaft of the stirring motor extending into the fermentation tank and fixedly connected to an eccentric wheel; several eccentric shafts are vertically mounted on the surface of the eccentric wheel, the upper end of the eccentric shaft is connected to a secondary drive assembly, and the lower end is coaxially fixedly connected to a linkage rod; the upper and lower ends of the linkage rod are respectively fixed to a first connecting seat and a second connecting seat with circular structures, and multiple vertical stirring rods are evenly arranged circumferentially between the first connecting seat and the second connecting seat; a support rod is fixed at the center of the lower surface of the eccentric wheel, the lower end of the support rod is rotatably connected to a support seat, and fixed rods are evenly arranged on the outer circumference of the support seat, the end of the fixed rod being rotatably connected to the bottom end of the corresponding linkage rod through a bearing.

[0010] Preferably, the secondary drive assembly includes a driven gear fixed to the upper end of the eccentric shaft; the upper surface inside the fermenter is provided with an annular drive tooth groove coaxial with the eccentric wheel, the outer teeth of the driven gear mesh with the inner teeth of the annular drive tooth groove, and when the eccentric wheel rotates, it drives the stirring rod to perform a circular stirring motion around the axis of the linkage rod through gear meshing.

[0011] Preferably, the gas injection unit includes multiple sets of gas injection rings arranged vertically and evenly along the axis of the fermenter, the gas injection rings being embedded in the inner wall of the fermenter; the inner wall of the gas injection rings is evenly provided with a plurality of gas injection holes, the gas injection holes being provided with a one-way membrane, and all gas injection rings being uniformly connected to an external aseptic gas injection device for supplying aseptic gas into the fermenter.

[0012] This invention also discloses a method for using an intelligent, quantitative fermentation device for supplying food and medicine homologous products, comprising the following steps: S1. Different types of food and medicine homologous fermented materials are put into the first feeding hopper and the second feeding hopper respectively, and the sealing cover is fastened and the hopper is sealed by the double-layer sealing component. S2. Change the metering wheel according to the material form, start the drive motor, and complete the precise material feeding through the metering wheel; close the second sealing valve, open the first sealing valve, and feed the material into the buffer chamber through the metering wheel. After the material feeding is completed, close the first sealing valve, open the air exchange valve to replace the air inside the buffer chamber, and then open the second sealing valve to transport the material into the fermentation tank in an oxygen-free manner. S3. Match the working conditions according to the fermentation process. During anaerobic fermentation, close the gas injection unit.

With the help of the secondary drive component, achieve low-speed rotation, uniformly mix the materials and improve the dissolved oxygen effect. S4. After the fermentation process is completed, open the bottom discharge pipe to discharge the fermented food and medicine homology finished product.

[0013] Therefore, the present invention, employing the above-mentioned intelligent quantitative supply fermentation device and its method for producing food and medicine of the same origin, has the following technical advantages: (1) The present invention is equipped with two independent feeding chambers, which can store solid and liquid fermentation materials of food and medicine homology respectively, realize the classification and independent feeding of solid and liquid materials, and avoid the defects of single feeding structure that cannot be adapted to the fermentation of compound materials; with two independent quantitative units, different types of quantitative tanks can be changed according to the material form, accurately control the material feeding ratio, ensure the rationality of the fermentation substrate ratio from the source, and improve the fermentation quality of the finished product.

[0014] (2) The filling hopper cover of the present invention is equipped with an annular baffle and a double-layer sealing component. The double-layer sealing ring, together with the connecting column and the special sealing groove structure, forms a double sealing protection structure. Compared with the traditional single-layer sealing structure, the sealing level is higher, which can effectively isolate external water vapor, bacteria and oxygen, prevent the material inside the hopper from getting damp and oxidized, and be contaminated by bacteria. At the same time, it avoids the loss of volatile materials and extends the material storage cycle.

[0015] (3) The present invention adds a buffer feeding unit. Through the coordinated cooperation of the double sealing valve and the air exchange valve, the air inside the buffer chamber can be replaced before the material is fed, so as to realize oxygen-free feeding and avoid the problem of food and medicine homologous active materials oxidizing and deteriorating when in contact with air. At the same time, the connecting pipeline is equipped with an anti-backflow check valve, which can block the backflow of materials and gas in the fermenter into the feeding structure, and ensure the stability of the entire feeding system and the sterile fermentation environment inside the fermenter.

[0016] (4) The stirring unit of the present invention adopts a dual driving mode of revolution + rotation. The eccentric wheel drives multiple sets of stirring rods to complete a large-scale global revolution, eliminating the blind spot of stirring in the fermentation tank. Relying on the meshing of the annular driving tooth groove and the driven gear, the single set of stirring rods is driven to rotate at low speed, which enhances the local material mixing effect. The combination of the two can greatly improve the uniformity of solid-liquid mixtures and optimize the dissolved oxygen distribution in the tank under aerobic fermentation conditions, which is suitable for the fermentation needs of high viscosity, multi-component food and medicine homology materials.

[0020] The technical solution of the present invention will be further described below with reference to the accompanying drawings and embodiments.

Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0022] like Figures 1 to 11 As shown, a fermentation device for intelligent quantitative supply of food and medicine homology food has a main structure including a vertical cylindrical fermentation tank 1. The top of the fermentation tank 1 is symmetrically and fixedly equipped with a first feeding chamber 2 and a second feeding chamber 3. The first feeding chamber 2 is used to store solid food and medicine homology fermentation raw materials, and the second feeding chamber 3 is used to store liquid fermentation materials such as plant extracts and fermentation liquid, so as to realize the independent storage of solid and liquid materials.

[0023] The first feeding bin 2 and the second feeding bin 3 are respectively equipped with the first quantitative unit 4 and the second quantitative unit 5 at their discharge ends. The two sets of quantitative units are the core structure for quantitative material supply. The discharge ends of the quantitative units are connected to the first buffer feeding unit 6 and the second buffer feeding unit 7. The buffer feeding unit serves as a transfer structure to complete the anaerobic feeding operation. The fermentation tank 1 integrates a stirring unit 8 and an aeration unit 9, which are responsible for mixing and stirring the materials and regulating the oxygen in the tank, respectively. The discharge pipe 10 is connected to the center of the bottom of the fermentation tank 1. The discharge pipe 10 is equipped with an electrically controlled valve for the automatic discharge of the finished product after fermentation.

[0024] Both the first filling bin 2 and the second filling bin 3 are set as a circular cylindrical integrated steel structure. A circular cover plate 11 can be detachably installed at the opening position at the upper end of the bin. The cover plate 11 is fixed to the bin by bolt locking, which is convenient for disassembly and assembly and facilitates the replenishment of materials by the staff.

[0025] An annular baffle 12 and a double-layer sealing assembly are coaxially welded to the lower surface of the cover plate 11. The inner diameter of the annular baffle 12 matches the outer wall of the injection chamber. After assembly, the inner wall of the annular baffle 12 fits tightly against the outer wall of the injection chamber, achieving initial positioning and dust protection. The double-layer sealing assembly consists of a first sealing ring 13 and a second sealing ring 14 arranged in parallel. Both sealing rings are made of food-grade silicone, which is corrosion-resistant, high-temperature resistant, non-toxic, and harmless, and meets food production standards. 4-6 sets of connecting posts 15 are welded in a circumferential array between the two sets of sealing rings to ensure the stability of the sealing ring structure. Correspondingly, a first sealing groove 38, a second sealing groove 39, and a connecting hole 40 are sequentially opened at the upper opening of the injection chamber. After the cover plate 11 is assembled, the first sealing ring 13, the second sealing ring 14, and the connecting post 15 are respectively embedded into the corresponding grooves and holes, forming a double-sealed structure that completely blocks the exchange of gases between the inside and outside.

[0026] The first metering unit 4 includes a sealed first sealing cavity 16, which is connected to the discharge port of the first filling bin 2 via a flange structure, ensuring no material leakage. Inside the first sealing cavity 16, a first metering wheel 17 is horizontally rotatably mounted, and 6-8 sets of metering grooves 18 are arranged in a ring around the outer periphery of the metering wheel 17. For solid materials, a rectangular deep groove with a depth of 20-30mm is selected, and the amount of solid material dispensed at one time is fixed by relying on the volume of the groove. For liquid materials, an arc-shaped shallow groove is selected, and the quantitative dispensing is completed by utilizing the surface tension of the liquid and the volume of the groove.

[0027] The first metering wheel 17 is coaxially fixedly connected to the shafts on both sides. The outer connecting shaft passes through the first sealed cavity 16 and is connected to the servo drive motor 19. The servo motor can precisely control the rotation angle and speed of the metering wheel 17, thereby adjusting the amount and rate of material fed at one time. The internal structure, size and driving method of the second metering unit 5 are completely the same as those of the first metering unit 4, and it can independently complete the quantitative feeding operation of liquid materials.

[0028] The first buffer feeding unit 6 includes a cylindrical sealed first buffer chamber 20. The upper feed end of the first buffer chamber 20 is connected to the lower discharge end of the first sealed chamber 16 by welding. The lower end of the first buffer chamber 20 is connected to the inner cavity of the fermenter 1 through a corrosion-resistant food-grade pipe. A backflow prevention check valve 21 is connected in series in the middle of the pipe. The check valve 21 only allows the material to flow into the fermenter 1 in one direction, thus preventing the backflow of material and fermentation gas.

[0029] The first buffer chamber 20 is equipped with an electrically controlled first sealing valve 22 and a second sealing valve 23 from top to bottom. The two sealing valves divide the buffer chamber into three independent areas: upper, middle and lower. A ventilation valve 24 is installed through the side wall of the buffer chamber. The ventilation valve 24 is connected to a vacuum replacement device and a sterile gas supply device, which can extract the air inside the buffer chamber and fill it with sterile inert gas to achieve an oxygen-free feeding environment. The second buffer feeding unit 7 has the same structure as the first buffer feeding unit 6 and is suitable for the oxygen-free transfer and delivery of liquid materials.

[0030] The stirring unit 8 includes a vertical stirring motor 25, which is fixed to the center of the top of the fermentation tank 1 by bolts. The output shaft of the stirring motor 25 extends vertically downward into the interior of the fermentation tank 1, and the bottom end is fixedly connected to an eccentric wheel 26.

[0031] Three to five sets of eccentric shafts 27 are vertically mounted through the surface of the eccentric wheel 26. A secondary drive assembly is mounted on the upper end of each eccentric shaft 27, and a cylindrical linkage rod 28 is coaxially fixed to the lower end. A circular first connecting seat 29 and a second connecting seat 30 are welded to the upper and lower ends of the linkage rod 28, respectively. Four vertical stainless steel stirring rods 31 are evenly distributed around the circumference between the two seats, forming an independent stirring assembly. A support rod 32 is vertically welded to the center of the lower surface of the eccentric wheel 26. The lower end of the support rod 32 is rotatably connected to a circular support seat 33. A fixed rod 34 is fixed to the outer circumference of the support seat 33 according to the number of stirring assemblies. The end of the fixed rod 34 is rotatably connected to the bottom end of the linkage rod 28 through a sealed bearing, providing support and limiting for the stirring assembly and reducing vibration amplitude during revolution.

[0032] The secondary drive assembly includes a driven gear 35 fixed to the upper end of the eccentric shaft 27. An annular drive tooth groove 36, coaxially arranged with the eccentric wheel 26, is formed on the inner top wall of the fermenter 1. Meshing teeth are machined on the inner side of the annular drive tooth groove 36. The outer teeth of the driven gear 35 mesh with the inner teeth of the annular drive tooth groove 36. During operation, the stirring motor 25 drives the eccentric wheel 26 to revolve, causing the driven gear 35 to move in a circular motion along the annular drive tooth groove 36. Relying on the meshing force of the gears, the eccentric shaft 27 and the stirring rod 31 rotate slowly around their own axes, achieving a combined revolution and rotation stirring mode.

[0033] The gas injection unit 9 comprises 3-4 sets of equidistant, vertically arranged annular gas injection rings 37. Each gas injection ring 37 is embedded and fixed within a pre-set groove on the inner wall of the fermenter 1, facilitating easy disassembly and maintenance. The inner wall of each gas injection ring 37 has evenly spaced micro-injection holes with a diameter of 2-3 mm. These holes are fitted with food-grade rubber one-way membranes, which allow sterile gas to flow only in one direction into the fermenter, preventing fermentation materials from seeping into the gas injection rings 37 and causing blockages. All gas injection rings 37 are connected to an external sterile gas injection device via an integrated main pipe. Operators can individually control the start and stop of each set of gas injection rings 37, achieving differentiated oxygen control in multiple areas (upper, middle, and lower) within the fermenter.

[0034] A method for using a fermentation device for intelligently and quantitatively supplying food that is both food and medicine includes the following steps: S1. Material loading and sealing: The staff opens the cover plates 11 of the two sets of feeding hoppers, puts the pre-treated solid food and medicine homologous raw materials into the first feeding hopper 2, and puts the liquid fermentation liquid and auxiliary materials into the second feeding hopper 3; after the feeding is completed, the cover plates 11 are fastened, and the cover plates are pressed so that the double-layer sealing components are completely embedded in the corresponding sealing grooves. The cover plates are locked with bolts to complete the all-round sealing of the hopper and isolate external bacteria and oxygen.

[0035] S2. Precise Anaerobic Quantitative Feeding: Based on the material morphology, a rectangular deep-groove quantitative wheel is installed inside the first quantitative unit 4, and an arc-shaped shallow-groove quantitative wheel is installed inside the second quantitative unit 5; the operating parameters of the servo drive motor 19 are set to determine the single feeding amount and feeding frequency. In the initial state, the second sealing valve 23 is closed, the first sealing valve 22 is opened, the drive motor 19 is started, and the quantitative wheel 17 rotates, causing the material to fall into the buffer chamber 20; after feeding is completed, the first sealing valve 22 is closed, the ventilation valve 24 is opened, the air inside the buffer chamber 20 is extracted and sterile nitrogen is introduced to complete the air replacement; finally, the second sealing valve 23 is opened, and the material is anaerobically transported to the fermenter 1 through the connecting pipe and check valve 21, completing the feeding operation.

[0036] S3. Fermentation Condition Control: Operators adjust equipment operating conditions according to fermentation process requirements. For anaerobic fermentation of probiotics, all aeration rings 37 are closed to maintain a sealed, oxygen-free environment in fermenter 1. For aerobic fermentation of molds and yeasts, aeration rings 37 at the corresponding height are activated based on the material level in the tank to introduce sterile air into the designated area and adjust the dissolved oxygen concentration. Simultaneously, the stirring motor 25 is started, and the eccentric wheel 26 drives multiple stirring components to rotate throughout the entire area. At the same time, the driven gear 35, in conjunction with the annular drive tooth groove 36, drives the stirring rod 31 to rotate. This dual stirring mode works in tandem to mix materials and optimize dissolved oxygen distribution.

[0037] S4. Automated Discharge: After the fermentation operation is completed according to the preset fermentation temperature, time and dissolved oxygen parameters, the stirring unit 8 and the gas injection unit 9 are turned off, the electrically controlled valve of the bottom discharge pipe 10 is opened, and the finished food and medicine homologous fermented material in the tank is discharged under the action of gravity. After the discharge is completed, the valve is closed and the tank waits for the next round of production.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solutions of the present invention, and these modifications or equivalent substitutions cannot cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.
