Description

Technical Field

[0001] The invention relates to the technical field of fermentation devices, in particular to a probiotic fermentation device. Background Art

[0002] Probiotics are a class of active microorganisms that are beneficial to the host. They mainly colonize in the human intestines and reproductive system and can produce definite health effects, thereby improving the host's microecological balance and playing a beneficial role.

[0003] In the probiotic fermentation process, the existing fermentation methods often use a simple stirring method. However, this method cannot ensure that the probiotics are fully combined with oxygen. Due to the uneven stirring, some probiotics may not be able to obtain sufficient oxygen supply, which will affect their growth rate and metabolic activity, and further affect the effect of the entire fermentation process and the quality of the final product. Therefore, finding a more effective oxygen contact and combination method is crucial to improving the probiotic fermentation efficiency.

[0004] In addition, existing fermentation devices usually only focus on probiotic stirring and temperature control but cannot efficiently capture and process the gases produced during the fermentation process of probiotics, which directly leads to the difficulty in achieving precise control of oxygen supply during aerobic respiration. Due to the lack of an effective gas collection mechanism, the gases produced by fermentation often diffuse at will, which not only causes a waste of resources, but also may have an adverse effect on the fermentation environment. At the same time, if the impurities and harmful substances that may be contained in the gas are not purified, once they are inhaled by probiotics, they will interfere with their normal physiological functions and metabolic activities, thereby affecting the stability of the fermentation process and the quality of the final product. Due to the inability to accurately measure and adjust the oxygen concentration in the fermentation environment, existing fermentation devices often cannot meet the precise control of the probiotics' oxygen demand, which may result in the probiotics being unable to obtain the best oxygen supply during aerobic respiration, thereby affecting their growth rate and the accumulation of metabolites.

[0005] Therefore, a probiotic fermentation device is proposed to solve the above problems. Summary of the invention

[0027] (2) Clean and disinfect: Clean and disinfect the stirring system and its contacting parts to eliminate potential pollution sources and ensure a sterile environment for the fermentation process;

[0030] (2) Set parameters: According to the technological requirements of probiotic fermentation, set parameters such as the rotation speed of the aerated shaft and the stirring time through the control system;

[0037] (2) Clean and maintain: After shutdown, thoroughly clean and maintain the stirring system and its contacting parts.

[0038] Compared with the prior art, the present invention provides a probiotic fermentation device, which has the following beneficial effects:

[0039] 1. In this solution, when the buffer block (23) slides down, the auxiliary plate (24) can drive the gas collecting plate (12) to reciprocate on the inner wall of the fermentation tank (1). Since a sealed space is formed between the gas collecting plate (12) and the inner wall of the fermentation tank (1), when the gas collecting plate (12) slides on the inner wall of the fermentation tank (1), the gas below the gas collecting plate (12) in the fermentation tank (1) is compressed. Through reciprocating compression, the gas can be more effectively mixed with the culture medium, ensuring that probiotics can obtain sufficient oxygen and other necessary gas components during the fermentation process, thereby promoting their growth and metabolism. At the same time, it is also beneficial to break the interfacial tension between the gas and the culture medium, making it easier for the gas to penetrate into the culture medium, and promoting the gas exchange inside the culture medium, improving the fermentation efficiency.

[0040] 2. The fine exhaust holes are evenly distributed in the ventilation stirring plate (33) to ensure the uniform distribution and precise supply of oxygen. The ventilation stirring plate (33) is firmly connected to the middle part of the ventilation shaft (14) to form an efficient oxygen transmission and mixing system. This system can quantitatively supply the required amount of oxygen to the fermentation tank (1) to meet the needs of the growth and metabolism of probiotics.

[0041] Compared with the prior art, when the ventilation shaft (14) rotates under the action of the driving force, it will drive the ventilation stirring plate (33) to move together, and comprehensively stir the mixed bacteria in the fermentation container. This stirring process not only promotes the uniform distribution of the bacteria, but also greatly enhances the contact opportunity between the bacteria and oxygen, thus significantly improving the fermentation rate and efficiency of probiotics.

[0042] 3. In this solution, a condensation filter screen (41) is added above the gas collecting plate (12). By cooling the condensation filter screen (41), the gas generated inside the fermentation tank (1) will form small liquid beads and adhere to the bottom of the condensation filter screen (41). At this time, when the ventilation shaft (14) rotates, it drives the middle scraper of the double-groove water collecting scraper (42) to scrape the bottom of the condensation filter screen (41). This can not only evenly collect the small liquid beads attached to the bottom of the condensation filter screen (41) into the water collecting grooves opened on both sides of the double-groove water collecting scraper (42). When the double-groove water collecting scraper (42) rotates to the upper drainage hole of the fermentation tank (1), the water in the water collecting groove of the double-groove water collecting scraper (42) will flow into the collecting tank (43) along the drainage hole for collection. The whole process is carried out in a closed environment.

[0043] Compared with the prior art, this solution not only effectively purifies the gas generated during the probiotic fermentation process, but also reasonably collects and utilizes these gases through an innovative collection mechanism. In addition, based on the gas generated by the fermentation of beneficial bacteria in the prior art, the oxygen injection volume can be calculated, so that the oxygen volume to be added to the main structure fermentation tank (1) can be accurately calculated, further improving the accuracy and controllability of the fermentation process. Moreover, this solution also fully considers the potential impact of the water droplets that may be generated at the bottom of the cooling component condensation filter screen (41) on the mixture fermentation. Through a clever scraper design and an accurate drainage mechanism, we have successfully avoided the dripping of water droplets and ensured the stability and purity of the fermentation environment.

[0056] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0057] The following further describes the present invention in detail according to the drawings and embodiments;

[0058] First embodiment

[0059] Please refer to Figures 1 to 7 as shown:

[0060] To solve the problems mentioned in the technical solution, the embodiment of the present application provides a probiotic fermentation device, including a fermentation tank 1, a tank cover 11 is installed on the fermentation tank 1, a fixing plate 13 is fixedly connected to the inner wall of the fermentation tank 1, a gas collection plate 12 is slidably connected above the fixing plate 13 on the inner wall of the fermentation tank 1, a ventilation shaft 14 is rotatably connected to the middle of the tank cover 11, the middle of the gas collection plate 12 is slidably connected to the outer surface of the ventilation shaft 14, and the middle outer surface of the ventilation shaft 14 is rotatably connected to the fixing plate 13. It also includes a fermentation collection mechanism 2, a multi-functional stirring fermentation mechanism 3, and a purification and cleaning mechanism 4;

[0061] Fermentation collection mechanism 2;

[0062] The fermentation collection mechanism 2 is arranged on the upper surface of the fixing plate 13, and the fermentation collection mechanism 2 is used for the fixing plate 13 to slide on the inner wall of the fermentation tank 1;

[0063] Multi-functional stirring fermentation mechanism 3;

[0064] The multi-functional stirring fermentation mechanism 3 is arranged on the ventilation shaft 14; the multi-functional stirring fermentation mechanism 3 is used for the uniform fermentation of probiotics;

[0065] Purification and cleaning mechanism 4;

[0066] The purification and cleaning mechanism 4 is arranged above the gas collection plate 12; the purification and cleaning mechanism 4 is used for the purification during the collection of probiotic fermentation gas;

[0067] Specifically, as Figure 3 shown, the threaded sleeve 21 is threadedly connected to the middle outer surface of the ventilation shaft 14, the elliptical extrusion plate 22 is fixedly connected to the outer surface of the ventilation shaft 14, buffer blocks 23 are symmetrically slidably connected to the upper surface of the fixing plate 13, and arc surface extrusion grooves are opened on one side of the buffer blocks 23 close to the elliptical extrusion plate 22;

[0068] The rotation of the ventilation shaft 14 can drive the elliptical extrusion plate 22 to rotate synchronously. Since the buffer block 23 is provided with an extrusion groove and is extruded with the outer periphery of the elliptical extrusion plate 22, the extrusion of the elliptical extrusion plate 22 will drive the buffer block 23 to slide on the upper surface of the fixed plate 13;

[0069] Furthermore, a buffer spring 25 is fixedly connected to the side of the buffer block 23 away from the elliptical extrusion plate 22. One end of the buffer spring 25 away from the buffer block 23 is fixedly connected to a limit block 26. The bottom of the limit block 26 is fixedly connected to the fixed plate 13. An auxiliary plate 24 is rotatably connected to the upper surface of the buffer block 23. One end of the auxiliary plate 24 away from the buffer block 23 is rotatably connected to the bottom of the air collecting plate 12. The air collecting plate 12 is uniformly provided with exhaust holes, and a one-way exhaust valve 27 is installed in the exhaust holes of the air collecting plate 12;

[0070] Wherein the buffer block 23 to the limit block 26 are symmetrically arranged on both sides of the elliptical extrusion plate 22.

[0071] In this solution, the reciprocating sliding of the air collecting plate 12 on the inner wall of the fermentation tank 1 can be driven by the buffer block 23 through the auxiliary plate 24. Since a closed space is formed between the air collecting plate 12 and the inner wall of the fermentation tank 1, when the air collecting plate 12 slides on the inner wall of the fermentation tank 1, the gas below the air collecting plate 12 in the fermentation tank 1 can be compressed; through reciprocating compression, the gas and the culture medium can be more effectively mixed, ensuring that the probiotics can obtain sufficient oxygen and other necessary gas components during the fermentation process, thereby promoting their growth and metabolism. At the same time, it is also beneficial to break the interfacial tension between the gas and the culture medium, making the gas more easily penetrate into the culture medium, and also promoting the gas exchange inside the culture medium, improving the fermentation efficiency.

[0072] Specifically, as Figure 5 and Figure 6 shown, the air storage chamber 31 is installed at the upper end of the ventilation shaft 14. An arc-shaped pushing plate 32 is fixedly connected to the outer surface of the ventilation shaft 14 near the lower part of the fixed plate 13. The outer surface of the ventilation shaft 14 is uniformly and fixedly communicated with ventilation stirring plates 33. The outer surface of the ventilation stirring plates 33 is fixedly connected to the arc-shaped pushing plate 32. One end of the ventilation stirring plates 33 away from the arc-shaped pushing plate 32 is fixedly connected to a vertical scraping plate 34;

[0073] Among them, micro-exhaust holes are uniformly distributed in the ventilation stirring plates 33 to ensure the uniform distribution and precise supply of oxygen. The ventilation stirring plates 33 are firmly connected to the middle part of the ventilation shaft 14 to form an efficient oxygen transmission and mixing system, which can quantitatively provide the required amount of oxygen into the fermentation tank 1 to meet the needs of the growth and metabolism of probiotics.

[0074] Compared with the prior art, when the ventilation shaft 14 rotates under the action of a driving force, it will drive the ventilation stirring plate 33 to move together, and comprehensively stir the mixed bacteria in the fermentation container. This stirring process not only promotes the uniform distribution of the bacteria, but also greatly enhances the contact opportunity between the bacteria and oxygen, thus significantly improving the fermentation rate and efficiency of probiotics.

[0075] A motor is installed on the tank cover 11, and the motor drive shaft is connected to the outer surface of the upper end of the ventilation shaft 14 through a belt drive. At the same time, the air storage chamber 31 is fixedly connected to the air inlet pipe of the oxygen input booster pump.

[0076] Further, the middle of the first gear 35 is fixedly connected to the bottom of the ventilation shaft 14. A second gear 36 is arranged on the outer circumference of the first gear 35. The tooth surface of the second gear 36 meshes with the first gear 35. The tooth surface of the second gear 36 on the side away from the first gear 35 meshes with an internal gear ring 37. The outer side of the internal gear ring 37 is rotatably connected to the bottom of the fermentation tank 1. The upper circumference of the internal gear ring 37 is fixedly connected to an air scraping plate 38. One end of the air scraping plate 38 away from the internal gear ring 37 is fixedly connected to an arc-shaped oxygen supply scraping plate 39. One-way ventilation valves are evenly installed in the arc-shaped oxygen supply scraping plate 39;

[0077] A gas collection device is arranged above the condensation filter screen 41, which can collect the preliminarily purified gas.

[0078] In this solution, the reverse movement of the internal gear ring 37 can be achieved by arranging the first gear 35 and the second gear 36 at the bottom of 4. At the same time, in this solution, by rotating the arc-shaped oxygen supply scraping plate 39 on the inner wall of the fermentation tank 1, not only can the phenomenon of stirring and supplementing on the inner wall of the fermentation tank 1 be prevented, but also the blockage of the one-way ventilation valve openings on the surface of 30 can be effectively reduced by the mutual scraping between the vertical scraping plate 34 and the arc-shaped oxygen supply scraping plate 39.

[0079] Specifically, as Figure 7 shown, the condensation filter screen 41 is installed on the inner wall of the fermentation tank 1 above the gas collecting plate 12. A double-groove water collecting scraping plate 42 is arranged at the bottom of the condensation filter screen 41. The double-groove water collecting scraping plate 42 is fixedly connected to the outer surface of the ventilation shaft 14. A convex scraping plate is arranged in the middle of the double-groove water collecting scraping plate 42. Water collecting grooves are opened on both sides of the convex scraping plate of the double-groove water collecting scraping plate 42; A collecting groove 43 is installed on the outer surface. A drain hole is opened in the fermentation tank 1 near the collecting groove 43. One end of the double-groove water collecting scraping plate 42 away from the ventilation shaft 14 is slidably connected to the inner wall of the fermentation tank 1, and the water collecting groove of the double-groove water collecting scraping plate 42 and the drain hole opened in the fermentation tank 1 are at the same level;

[0080] In this solution, a condensation filter screen 41 is added above the air collecting plate 12. By cooling the condensation filter screen 41, the gas generated inside the fermentation tank 1 will form small liquid beads when encountering the cold and adhere to the bottom of the condensation filter screen 41. At this time, when the ventilation shaft 14 rotates, the middle scraper of the double-groove water collecting scraper 42 scrapes the bottom of the condensation filter screen 41. This can not only evenly collect the small liquid beads attached to the bottom of the condensation filter screen 41 into the water collecting grooves opened on both sides of the double-groove water collecting scraper 42, but also when the double-groove water collecting scraper 42 rotates to the upper drainage hole of the fermentation tank 1, the water in the water collecting groove of the double-groove water collecting scraper 42 will flow into the collecting tank 43 along the drainage hole for collection. The whole process is carried out in a closed environment;

[0081] Compared with the prior art, this solution not only effectively purifies the gas generated during the probiotic fermentation process, but also reasonably collects and utilizes these gases through an innovative collection mechanism. In addition, through the prior art, the oxygen injection amount can be calculated based on the gas generated by the beneficial bacteria fermentation, so that the oxygen amount required to be added to the main structure fermentation tank 1 can be accurately calculated, further improving the accuracy and controllability of the fermentation process. And this solution also fully considers the potential impact of the water droplets that may be generated at the bottom of the cooling component condensation filter screen 41 on the mixture fermentation. Through a clever scraper design and an accurate drainage mechanism, we have successfully avoided the dripping of water droplets and ensured the stability and purity of the fermentation environment.

[0082] Second Embodiment

[0083] A method for fermenting probiotic agents, including:

[0084] S1, Preparation stage: Clean and disinfect the fermentation tank 1 and related accessories in the fermentation tank 1. According to the production formula of the probiotic agent, prepare the required raw materials. At the same time, check whether the functions of the fermentation device are normal to ensure that the equipment is in good condition and can meet the requirements of the fermentation process;

[0085] S2, Inoculation and cultivation stage: Under sterile conditions, inoculate the probiotic strains into the prepared fermentation tank 1. The inoculation amount should be reasonably controlled according to the production formula and the characteristics of the strains. According to the growth characteristics of the probiotics, set appropriate cultivation conditions, start the stirring system to evenly distribute the nutrients and probiotics in the culture medium, and adjust the ventilation volume of the air storage chamber 31 above the ventilation shaft 14 as needed to ensure that the probiotics obtain sufficient oxygen for respiration;

[0086] S3, Fermentation and monitoring stage: Real-time monitor various parameters during the fermentation process through sensors and control systems. Once abnormalities are found, measures should be taken immediately for adjustment. Regularly take samples to detect indicators such as the number, activity of the probiotics, and the content of metabolites. These detection data can provide a basis for subsequent production optimization.

[0087] A method for fermenting probiotic agents. The operation steps of starting the stirring system described in S2 include:

[0088] S2.1. Preparation stage:

[0089] (1) Check the stirring system: Before starting the stirring system, first check whether components such as the arc-shaped pushing plate 32, the ventilation stirring plate 33, the vertical scraping plate 34, the motor, the ventilation shaft 14, and the control system are intact to ensure that the stirring system can operate normally;

[0090] (2) Cleaning and disinfection: Clean and disinfect the stirring system and its contacting parts to eliminate potential pollution sources and ensure a sterile environment for the fermentation process;

[0091] S2.2. Starting and debugging stage

[0092] (1) Connect the power supply: Correctly connect the power cord of the stirring system to the power socket and ensure that the power supply voltage is stable and meets the equipment requirements;

[0093] (2) Set parameters: According to the technological requirements of probiotic fermentation, set parameters such as the rotation speed of the ventilation shaft 14 and the stirring time through the control system;

[0094] 3 Start stirring: After confirming that all settings are correct, start the stirring system, and the stirrer starts to rotate at the set speed, driving the culture medium to mix and distribute evenly;

[0095] When the motor installed above the tank cover 11 starts, the rotation of the motor will drive the ventilation shaft 14 to start rotating synchronously. At this time, when the ventilation shaft 14 rotates, it will directly drive the arc-shaped pushing plate 32, the ventilation stirring plate 33, and the vertical scraping plate 34 on the ventilation shaft 14 to rotate synchronously. The rotation of the arc-shaped pushing plate 32 will push the mixed bacteria at the bottom of the fermentation tank 1 towards the upper part of the fermentation tank 1. At this time, the vertical scraping plate 34 can drive the mixed colonies in the fermentation tank 1 to be continuously stirred. At the same time, as Figure 6 shown, the rotation of the ventilation shaft 14 will drive the first gear 35 to drive the second gear 36. The meshing of the second gear 36 with the internal gear ring 37 will cause the air scraping plate 38 to drive the arc-shaped oxygen-permeating scraping plate 39 to start rotating in the opposite direction to the ventilation shaft 14. At this time, the rotation of the arc-shaped oxygen-permeating scraping plate 39 can fully stir the mixture on the inner wall of the fermentation tank 1, and the contact between the vertical scraping plate 34 and the arc-shaped oxygen-permeating scraping plate 39 can effectively scrape the one-way air inlet holes inside the arc-shaped oxygen-permeating scraping plate 39 to prevent blockage. Moreover, through the combined stirring of the ventilation stirring plate 33 and the arc-shaped oxygen-permeating scraping plate 39, not only can the mixing uniformity of the colonies be increased, but also the blockage of the exhaust holes by the colonies can be effectively reduced;

[0096] S2.3. Monitoring and adjustment stage

[0097] (1) Observe the stirring effect: During the stirring process, closely observe the mixing situation in the fermentation tank 1. If problems such as uneven stirring or dead corners are found, the rotation speed or position of the stirrer should be adjusted in a timely manner to ensure that the cultured bacteria in the fermentation tank 1 can be fully mixed;

[0098] During its mixing and stirring process, as Figure 3 shown, when the ventilation shaft 14 rotates, it will drive the elliptical extrusion plate 22 to start rotating synchronously on the surface of the fixed plate 13. By the rotation of the elliptical extrusion plate 22, the buffer block 23 above the fixed plate 13 will start to slide reciprocally on the surface of the fixed plate 13. And through the reciprocating sliding of the buffer block 23, it will drive the air collecting plate 12 to reciprocate on the inner wall of the fermentation tank 1 to compress the gas at the bottom of the fermentation tank 1. And because bubbles will be generated during the stirring process, by continuously compressing the fermentation tank 1 through the air collecting plate 12, the generation of internal bubbles can be reduced. At the same time, since the one-way exhaust valves 27 are evenly installed on the air collecting plate 12, when gas is generated due to fermentation in the fermentation tank 1 and the gas below the air collecting plate 12 in the fermentation tank 1 reaches the threshold of the one-way exhaust valve 27, at this time, the one-way exhaust valve 27 will discharge the gas generated in the fermentation tank 1 through the one-way exhaust valve 27 to the upper part of the air collecting plate 12. At this time, its humid gas meets the condensation filter screen 41 whose surface is cooled by refrigeration. At this time, the humid gas will form small liquid beads attached to the bottom of the condensation filter screen 41. At this time, when the ventilation shaft 14 rotates, it drives the middle scraper of the double-groove water collecting scraper 42 to scrape the bottom of the condensation filter screen 41. Not only can the small liquid beads attached to the bottom of the condensation filter screen 41 be evenly collected into the water collecting grooves opened on both sides of the double-groove water collecting scraper 42, when the double-groove water collecting scraper 42 rotates to the drainage hole on the fermentation tank 1, the water in the water collecting groove of the double-groove water collecting scraper 42 will flow into the collecting groove 43 along the drainage hole for collection. The whole process is carried out in a closed environment;

[0099] Compared with the prior art, this solution not only realizes the effective purification of the gas generated during the probiotic fermentation process, but also reasonably collects and utilizes these gases through an innovative collection mechanism. In addition, through the existing technology, the injection amount of oxygen can be calculated based on the gas generated by the beneficial bacteria fermentation, so that the required oxygen amount to be added to the main structure fermentation tank 1 can be accurately calculated, further improving the accuracy and controllability of the fermentation process. And this solution also fully considers the potential impact of the water droplets that may be generated at the bottom of the cooling component condensation filter screen 41 on the mixture fermentation. Through a clever scraper design and an accurate drainage mechanism, we have successfully avoided the dripping of water droplets and ensured the stability and purity of the fermentation environment.
