TECHNICAL FIELD

[0001] The present application relates to the technical field of probiotic production, in particular to a separation and filtration device for probiotic production. BACKGROUND

[0002] The separation and filtration in probiotic production is a key link to ensure the activity, purity and quality of probiotics. The main function of separation and filtration is to separate probiotics with specific functions from complex microbial populations and remove impurities in the fermentation broth.

[0003] During the filtration process, temperature and pressure control are particularly important. Temperature fluctuations can affect the activity of probiotics, so control must be performed. And during the filtration process, pressure directly affects filtration efficiency and probiotic activity. Too high pressure can cause the filtration membrane to be more clogged, and can also cause mechanical damage to probiotics and insufficient filtration, affecting product purity. And probiotics in solution may aggregate and precipitate due to interaction, affecting the separation and filtration effect. Therefore, the above problems need to be improved. SUMMARY

[0011] As a preferred embodiment of the present invention: the centrifugal motor and the controller are electrically connected; the stirring shaft is electrically connected to the controller via a power supply; the diameter of the through hole is adapted to the diameter of the slide rod, and the through hole is sleeved on the outer wall of the slide rod; the stirring shaft is made of copper enameled wire, and the shape of the stirring shaft is a solenoid; the spiral plates are spirally distributed on the inner wall of the chamber, and the projected diameter of the spiral plates is adapted to the diameter of the circular groove; the filter membrane is a microfiltration and ultrafiltration membrane made of polyvinylidene fluoride.

[0012] As a preferred embodiment of the present invention: the temperature control component includes a friction roller, a bevel gear one is fixedly installed at the end of the friction roller away from the support frame, a bevel gear two meshes with the top of the bevel gear one, a small gear is fixedly installed on the top of the bevel gear two, a large gear meshes with the outer wall of the small gear, a rotating rod is fixedly installed on the top of the small gear, a heat collection cylinder is provided on the top of the large gear, a sealing cover is installed at the bottom of the heat collection cylinder, and a fixing sleeve is fixedly installed on the top of the inner wall of the heat collection cylinder.

[0013] As a preferred technical solution of the present invention: a central rotating shaft is rotatably sleeved on the inner wall of the fixed sleeve, a friction disk one is fixedly sleeved on the bottom outer edge of the fixed sleeve, a friction disk two is provided at the bottom of the friction disk one, a hot gas conveying pipe is clamped at one end of the heat collecting cylinder near the limiting installer, and an air inlet pipe is fixedly clamped on the outer wall of the end of the heat collecting cylinder away from the hot gas conveying pipe.

[0014] As a preferred embodiment of the present invention: the top of the rotating rod is rotatably connected to the bottom of the limiting installer; the top of the large gear is fixedly installed to the bottom of the central rotating shaft; the second friction disc is fixedly sleeved on the outer wall of the central rotating shaft; the hot gas conveying pipe is clamped to the inner wall of the limiting installer; and the end of the hot gas conveying pipe away from the heat collection cylinder is connected to the inner wall of the heating shell through a connecting groove; the friction roller rotates on the outer wall of the limiting installer; and the outer wall of the friction roller is in contact with the bottom of the filter disc.

[0015] The present invention has the following beneficial effects: 1. This probiotic production separation and filtration device, through the rotation of the filter disc, contacts the outer wall of the friction roller and rotates. It can also drive the rotation of the second bevel gear via the first bevel gear, causing the small gear to rotate and in turn driving the large gear. This allows the second friction disc to contact the bottom of the first friction disc during rotation, generating friction between them and converting this mechanical energy into heat energy. The heat generated is located at the top of the inner wall of the heat collection cylinder and can be transported to the inner wall of the heating shell through a hot air delivery pipe. This allows the inner wall of the chamber to maintain a temperature between 25℃ and 37℃, ensuring that the probiotics are kept at a suitable temperature during the separation and filtration process. Maintaining the filtration temperature is essentially the same as the fermentation temperature, preventing the probiotics from losing activity due to environmental changes. Temperature control ensures that the probiotics retain high activity and high purity after separation and filtration.

[0016] 2. This probiotic production separation and filtration device, activated by a centrifugal motor, causes the stirring shaft to rotate a spiral plate within the chamber. This accelerates the flow of the probiotic fermentation broth, and high-speed centrifugation separates the bacteria from the liquid, effectively improving separation efficiency. The stirring provides external force, ensuring the probiotics remain evenly dispersed in the solution. Continuous agitation disrupts the aggregation of probiotics, preventing them from forming large aggregates that settle to the bottom of the container. Simultaneously, the rotating stirring shaft causes a connecting shaft to rotate a scraper on top of the filter disc, scraping away impurities. The rotation of the spiral plate utilizes the properties of the filter membrane to effectively avoid adverse effects on the probiotics, improve filtration efficiency, and reduce the loss of probiotic activity during filtration.

[0017] 3. This probiotic production separation and filtration device uses a stirring shaft to drive a spiral plate to rotate at high speed inside the chamber. This causes the flocculent matter in the probiotics to adhere to the surface of the filter membrane, thus achieving the purpose of pre-treatment and separation of the probiotics. Multiple separations of the probiotics improve the extraction rate and enhance environmental performance. By controlling temperature and pressure, combined with efficient filtration and centrifugation technology, the production efficiency and product quality of probiotics can be significantly improved. Furthermore, by cleaning the filter discs, the frequency of filter disc replacement is reduced, further lowering production costs and improving the environmental friendliness of the process.

[0018] 4. The separation and filtration device for probiotic production has two sets of separation and filtration components and two sets of temperature control components, which enables the device to separate and filter two different probiotics at the same time. The bacteria left after separation and filtration flow to the inner wall of the chamber for final collection, which effectively improves the efficiency of the device in separating and filtering probiotics, while reducing working time and costs.

[0019] 5. This probiotic production separation and filtration device, when the filter disc rotates to the bottom of the limiting plate, can trigger the controller to send a signal to start the water pump. This pump draws water from the inner wall of the water tank onto the inner wall of the spray pipe, and sprays it from the nozzle onto the top of the filter disc. This cleans the top surface of the filter disc after use, ensuring it remains clean when it rotates to the bottom of the separation and filtration assembly again. This effectively prevents clogging after use and enables continuous separation and filtration of probiotics, improving separation efficiency and making the entire separation and filtration process more efficient.

[0020] 6. This probiotic production separation and filtration device, through a controller signal, can start a servo motor, enabling sprocket one to drive sprocket two to rotate via a chain. This causes the central rod to drive the turntables at both ends to rotate synchronously, thus causing the connecting rod to move in a circular motion around the virtual center line of the turntable. This, in turn, causes the sliding rod to slide up and down on the inner wall of the separation and filtration assembly, thereby pressing the probiotics on the inner wall of the separation and filtration assembly by the pressure plate. By controlling the pressure, the probiotics can be effectively induced to form a structure conducive to separation and filtration, thereby improving separation efficiency and product quality.

[0021] 7. This probiotic production separation and filtration device, when the controller sends a signal, allows current to pass through an electromagnetic coil, thereby generating a magnetic field around it. By changing the magnitude of the current flowing through the coil, the strength and direction of the magnetic field can be flexibly adjusted. This allows the target probiotics to be separated from other bacterial groups by utilizing the differences in surface charge and physical properties of the bacterial community. For some probiotics that carry charges or have magnetic responses, the magnetic field can change the interaction force between them, making the downward pressure effect more significant. Moreover, this combined action will produce some special physical changes inside the probiotics, further facilitating subsequent separation and filtration operations, while also increasing the uniqueness of the technology.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figure 1 - Figure 9A separation and filtration device for probiotic production includes a collection box 1, a filter disc 2 rotatably connected to the top of the collection box 1, a support frame 3 and a drive motor 16 fixedly installed on the bottom of the inner wall of the collection box 1, a pressure control component 4 provided on the outer wall of the support frame 3, a limit frame 5 and a limit installer 7 fixedly mounted at both ends of the support frame 3, a separation and filtration component 6 provided at the bottom of the limit frame 5, a temperature control component 8 provided at the end of the limit installer 7 away from the limit frame 5, a water tank 9 fixedly installed on the inner wall of the support frame 3, a water pump 10 provided on the inner wall of the water tank 9, a water spray pipe 11 installed at both ends of the water pump 10, a nozzle 12 fixedly mounted at the bottom of the water spray pipe 11, a limit plate 13 snapped onto the top of the water spray pipe 11, a filter hole 14 opened on the top of the filter disc 2, a driven gear 15 fixedly installed on the inner wall of the filter disc 2, the power output shaft of the drive motor 16 fixedly connected to the drive gear 17 through a coupling, and a limit seat 18 installed on the top of the support frame 3. In the above structure, through the setting of the support frame 3 and the installation position characteristics of the support frame 3, it can be seen that the support frame 3 can keep the device balanced and make the placement of the separation filter component 6 more stable. When probiotics are placed at different depths on the inner wall of the separation filter component 6, the device will not be unbalanced. At the same time, due to the setting of the limiting seat 18 and the installation position characteristics of the limiting seat 18, the limiting seat 18 can play a limiting role on the pressure control component 4, so that the pressure control component 4 will not easily fall off after installation.

[0026] In a preferred embodiment: there are two spray pipes 11, two nozzles 12 and two limiting plates 13, and the two spray pipes 11, two nozzles 12 and two limiting plates 13 are symmetrically distributed at both ends of the water tank 9. The water pump 10 is electrically connected to the controller. The end of the limiting plate 13 away from the nozzle 12 is fixedly installed on the outer wall of the water tank 9. The inner wall of the spray pipe 11 is connected to the inner wall of the nozzle 12. In the above structure, the controller sends a signal to start the water pump 10, which draws water from the inner wall of the water tank 9 to the inner wall of the spray pipe 11, and sprays it from the nozzle 12 onto the top of the filter disc 2. This allows the top surface of the filter disc 2 to be cleaned after use, ensuring that the filter disc 2 remains clean when it rotates to the bottom of the separation filter assembly 6 next time. This effectively prevents the filter disc 2 from becoming clogged after use and extends the service life of the filter disc 2.

[0027] In a preferred embodiment: the drive motor 16 is electrically connected to the controller, the outer wall of the drive gear 17 meshes with the driven gear 15, the filter disc 2 rotates on the top of the collection box 1 via the driven gear 15, the number of filter holes 14 is several, and the several filter holes 14 are evenly distributed on the top of the filter disc 2, the filter disc 2 is made of stainless steel, and the top of the filter disc 2 is in contact with the bottom of the separation filter assembly 6. In the above structure, the controller sends a signal to start the drive motor 16, which in turn causes the drive gear 17 to rotate. The driven gear 15, which meshes with the drive gear 17, drives the filter disc 2 to rotate, allowing the filter disc 2 to move in a circular motion at the bottom of the separation and filtration assembly 6. This enables the device to continuously filter probiotics. Furthermore, the rotation of the filter disc 2 facilitates other operations, thus effectively avoiding the need for frequent filter replacements, thereby improving filtration efficiency and reducing the risk of filter clogging. Meanwhile, because the filter disc 2 is made of stainless steel, it is known that the filter disc 2 will not easily rust or corrode, which can effectively ensure the service life of the filter disc 2 and reduce the replacement efficiency. It can also ensure that the device maintains the best effect of separating and filtering probiotics at all times, and there is no need to replace the filter disc 2 frequently, which reduces production costs and improves filtration efficiency.

[0028] In a preferred embodiment: the pressure control assembly 4 includes a mounting base 401, a servo motor 402 is fixedly mounted on the top of the mounting base 401, a sprocket 403 is fixedly mounted on the power output shaft of the servo motor 402 via a coupling, one end of a chain 404 is engaged with the outer wall of the sprocket 403, and the other end of the chain 404 is engaged with a sprocket 405, a center rod 406 is fixedly mounted at the center of the sprocket 405, a turntable 407 is fixedly mounted at both ends of the center rod 406, a fixing post 408 is fixedly mounted on the outer wall of the turntable 407, a connecting rod 409 is mounted at the bottom of the fixing post 408, one end of a mounting post 410 is mounted at the bottom of the connecting rod 409, and a sliding rod 411 is mounted at the other end of the mounting post 410, a lower pressure plate 412 is fixedly mounted at the bottom of the sliding rod 411, and a circular groove 413 is provided on the top of the lower pressure plate 412; In the above structure, the servo motor 402 can be started by the controller sending a signal, so that the first sprocket 403 can drive the second sprocket 405 to rotate through the chain 404. This can cause the central rod 406 to drive the turntables 407 at both ends to rotate synchronously, so that the connecting rod 409 can move in a circle around the virtual center line of the turntable 407. This can then drive the slide rod 411 to slide up and down on the inner wall of the separation filter assembly 6, so that the pressure plate 412 can press down on the probiotics on the inner wall of the separation filter assembly 6.

[0029] In a preferred embodiment: the servo motor 402 is electrically connected to the controller. There are two turntables 407, two fixed columns 408, two connecting rods 409, two mounting columns 410, two sliding rods 411, two pressure plates 412 and two circular grooves 413. The two turntables 407, two fixed columns 408, two connecting rods 409, two mounting columns 410, two sliding rods 411, two pressure plates 412 and two circular grooves 413 are symmetrically distributed at both ends of the central rod 406. The mounting base 401 is fixedly installed on the outer wall of the support frame 3. The diameter of the first sprocket 403 is smaller than the diameter of the second sprocket 405. The pressure plate 412 is located on the inner wall of the separation filter assembly 6. In the above structure, by controlling the rotation speed of the sprocket 403 to adjust the downward pressure of the slide bar 411, the initial pressure of the device can be controlled at a low level, and then the pressure can be slowly increased to ensure the stability of filtration and the integrity of probiotics. It can also meet the different aggregation or dispersion characteristics of different types of probiotics under different pressure conditions, and at the same time facilitate their separation by the filter disc 2. Furthermore, by controlling the downward pressure, the probiotics can be effectively induced to form a structure that is conducive to separation and filtration, thereby improving separation efficiency and product quality.

[0030] In a preferred embodiment: the separation and filtration assembly 6 includes a chamber 601, a top cover 602 is installed on the top of the chamber 601, a through hole 603 is opened on the top of the top cover 602, a centrifugal motor 604 is fixedly installed on the top of the top cover 602, a stirring shaft 605 is fixedly assembled on the power output shaft of the centrifugal motor 604 through a coupling, a spiral plate 606 is fixedly installed on the outer wall of the stirring shaft 605, an electromagnetic coil 607 is wound on the outer wall of the stirring shaft 605, a filter membrane 608 is embedded in the inner cavity of the spiral plate 606, a connecting shaft 609 is fixedly assembled on the bottom of the stirring shaft 605, a scraper 610 is fixedly installed on the outer wall of the connecting shaft 609, a heating shell 611 is sleeved on the outer wall of the chamber 601, and a connecting groove 612 is opened at the end of the heating shell 611 away from the through hole 603; In the above structure, the flow of probiotic fermentation broth in the spiral plate 606 achieves bacterial sedimentation and separation, reducing replacement time and improving filtration efficiency. Furthermore, a signal is sent by the controller to start the centrifugal motor 604, causing the stirring shaft 605 to drive the spiral plate 606 to rotate within the chamber 601. This accelerates the flow of the probiotic fermentation broth, and high-speed centrifugation separates the bacteria from the liquid, effectively improving separation efficiency. Simultaneously, during the rotation of the stirring shaft 605, the connecting shaft 609 drives the scraper 610 to rotate on top of the filter disc 2, allowing the scraper 610 to scrape the top of the filter disc 2, effectively reducing the risk of clogging and improving the ease of subsequent cleaning.

[0031] In a preferred embodiment: the centrifugal motor 604 is electrically connected to the controller, the stirring shaft 605 is electrically connected to the controller via a power source, the diameter of the through hole 603 is adapted to the diameter of the slide rod 411, and the through hole 603 is sleeved on the outer wall of the slide rod 411, the stirring shaft 605 is made of copper enameled wire, and the shape of the stirring shaft 605 is solenoid, the spiral plate 606 is spirally distributed on the inner wall of the chamber 601, the projected diameter of the spiral plate 606 is adapted to the diameter of the circular groove 413, and the filter membrane 608 is a microfiltration and ultrafiltration membrane made of polyvinylidene fluoride; In the above structure, the filter membrane 608 is compatible with the probiotic fermentation broth, which can effectively avoid adverse effects on the probiotics. The filter membrane 608 has the advantages of good chemical stability, non-toxicity, and non-adsorption of probiotics, thereby effectively reducing interference with the activity of probiotics and improving filtration efficiency. At the same time, it reduces the loss of probiotic activity during filtration. When the centrifugal motor 604 is started, it can drive the spiral plate 606 to rotate at high speed inside the chamber 601 through the stirring shaft 605, so that the flocculent matter in the probiotics will adhere to the surface of the filter membrane 608, thereby achieving the purpose of pre-treatment, separation and filtration of probiotics.

[0032] In a preferred embodiment: the temperature control assembly 8 includes a friction roller 801, a bevel gear 802 is fixedly installed at the end of the friction roller 801 away from the support frame 3, a bevel gear 803 meshes with the top of the bevel gear 802, a pinion 804 is fixedly installed with the top of the pinion 803, a large gear 805 meshes with the outer wall of the pinion 804, a rotating rod 806 is fixedly installed with the top of the pinion 804, a heat collection cylinder 807 is provided at the top of the large gear 805, a sealing cover 808 is installed at the bottom of the heat collection cylinder 807, and a fixing sleeve 810 is fixedly installed with the top of the inner wall of the heat collection cylinder 807. In a preferred embodiment: a central rotating shaft 809 is rotatably sleeved on the inner wall of the fixed sleeve 810, a friction disc 811 is fixedly sleeved on the bottom outer edge of the fixed sleeve 810, a second friction disc 812 is provided at the bottom of the first friction disc 811, a hot gas conveying pipe 813 is snapped into the end of the heat collection cylinder 807 near the limiting installer 7, and an air inlet pipe 814 is fixedly snapped into the outer wall of the end of the heat collection cylinder 807 away from the hot gas conveying pipe 813. In the above structure, through the setting of the air inlet pipe 814 and the positional characteristics of the air inlet pipe 814, it can be seen that the air inside the heat collection cylinder 807 can be transmitted through the air inlet pipe 814, so that the device can use air as a medium to convert the friction force generated between the filter disc 2 and the friction roller 801 during rotation into heat energy, and convert this heat into maintaining the temperature of the chamber 601, thus saving energy.

[0033] In a preferred embodiment: the top of the rotating rod 806 is rotatably connected to the bottom of the limiting mount 7, the top of the large gear 805 is fixedly installed to the bottom of the central rotating shaft 809, the friction disc 812 is fixedly sleeved on the outer wall of the central rotating shaft 809, the hot gas conveying pipe 813 is snapped into the inner wall of the limiting mount 7, and the end of the hot gas conveying pipe 813 away from the heat collection cylinder 807 is connected to the inner wall of the heating shell 611 through the connecting groove 612, the friction roller 801 rotates on the outer wall of the limiting mount 7, and the outer wall of the friction roller 801 is in contact with the bottom of the filter disc 2; In the above structure, the filter disc 2 contacts the outer wall of the friction roller 801 during rotation, causing the friction roller 801 to rotate. This rotation, via the first bevel gear 802, drives the second bevel gear 803 to rotate, which in turn drives the small gear 804 to rotate, and in turn drives the large gear 805 to rotate. This allows the second friction disc 812 to contact the bottom of the first friction disc 811 during rotation, generating friction between the two. This mechanical energy is converted into heat energy, which is then placed at the top of the inner wall of the heat collection cylinder 807 and transported to the inner wall of the heating shell 611 through the hot air delivery pipe 813. This allows the inner wall of the chamber 601 to maintain a temperature between 25℃ and 37℃, ensuring that the probiotics are kept at a suitable temperature during the separation and filtration process. Maintaining the filtration temperature is essentially the same as the fermentation temperature, preventing the probiotics from losing their activity due to environmental changes, and thus resulting in higher purity of the separated and filtered probiotics.

[0034] Working principle: When using this device, the probiotic fermentation liquid to be separated is poured onto the inner wall of the chamber 601. At this time, the controller can send a signal to start the drive motor 16, so that the drive gear 17 can rotate and the driven gear 15 meshing with the drive gear 17 can drive the filter disc 2 to rotate. The filter disc 2 can move in a circle at the bottom of the separation filter assembly 6, so that the device can filter the probiotics continuously. During this process, the controller sends a signal to start the servo motor 402, so that the first sprocket 403 can drive the second sprocket 405 to rotate through the chain 404. This can drive the central rod 406 to drive the turntables 407 at both ends to rotate synchronously, so that the connecting rod 409 moves in a circle around the virtual center line of the turntable 407. This can drive the slide rod 411 to slide up and down on the inner wall of the separation filter assembly 6, so that the pressure plate 412 can press down on the probiotics on the inner wall of the separation filter assembly 6. At this time, the controller sends a signal to start the centrifugal motor 604, causing the stirring shaft 605 to drive the spiral plate 606 to rotate on the inner wall of the chamber 601. This allows the spiral plate 606 to accelerate the flow of the probiotic fermentation broth, and the high-speed centrifugation separates the bacteria from the liquid, effectively improving separation efficiency. The stirring also provides external force, keeping the probiotics evenly dispersed in the solution. Continuous agitation breaks down the aggregation forces between the probiotics, preventing them from forming large aggregates and settling to the bottom of the container. Simultaneously, as the stirring shaft 605 rotates, the connecting shaft 609 drives the scraper 610 on the filter disc. The top of the filter plate 2 rotates, allowing the scraper 610 to scrape the top of the filter plate 2. During the rotation of the spiral plate 606, the characteristics of the filter membrane 608 are utilized to make the filter membrane 608 compatible with the probiotic fermentation liquid, which can effectively avoid adverse effects on the probiotics and improve filtration efficiency. At the same time, it reduces the loss of probiotic activity during filtration. When the centrifugal motor 604 starts, it can drive the spiral plate 606 to rotate at high speed inside the chamber 601 through the stirring shaft 605, so that the flocculent matter in the probiotics will adhere to the surface of the filter membrane 608, thereby achieving the purpose of pre-treatment separation and filtration of probiotics. Meanwhile, when the controller sends a signal, current will pass through the electromagnetic coil 607, thereby generating a magnetic field around it. By changing the magnitude of the current flowing into the coil, the strength and direction of the magnetic field can be flexibly adjusted, thereby using the differences in surface charge and physical properties of the bacterial community to separate the target probiotics from other bacterial communities. Furthermore, during the rotation of the filter disc 2, it comes into contact with the outer wall of the friction roller 801, causing the friction roller 801 to rotate. This rotation, via the first bevel gear 802, drives the second bevel gear 803 to rotate, which in turn drives the small gear 804 to rotate and in turn drives the large gear 805 to rotate. This allows the second friction disc 812 to come into contact with the bottom of the first friction disc 811 during rotation, generating friction between the first friction disc 811 and the second friction disc 812. This mechanical energy is converted into heat energy, which is then placed at the top of the inner wall of the heat collection cylinder 807 and transported to the inner wall of the heating shell 611 through the hot air delivery pipe 813. This allows the inner wall of the chamber 601 to maintain a temperature between 25℃ and 37℃ through the transported heat. This ensures that the probiotics are kept at a suitable temperature during the separation and filtration process, and that the filtration temperature is basically the same as the fermentation temperature, thereby resulting in higher purity of the separated and filtered probiotics. When the filter disc 2 rotates to the bottom of the limiting plate 13, the controller can send a signal to start the water pump 10, which will draw water from the inner wall of the water tank 9 to the inner wall of the spray pipe 11 and spray it from the nozzle 12 to the top of the filter disc 2. This will clean the top surface of the filter disc 2 after use, ensuring that the filter disc 2 remains clean when it rotates to the bottom of the separation filter assembly 6 next time. This effectively prevents the filter disc 2 from becoming clogged after use and enables continuous separation and filtration of probiotics. Since both the separation filter assembly 6 and the temperature control assembly 8 are set in two groups, the device can simultaneously separate and filter two different types of probiotics, and the bacteria remaining after separation and filtration are collected on the inner wall of the chamber 601.
