Description

Technical Field

[0001] This utility model relates to the field of fermentation tank technology, and more specifically, to a probiotic-milk fat dynamic stratified fermentation tank. Background Technology

[0002] As a core piece of equipment in the field of biomanufacturing, the fermentation tank's core function is to provide a controllable metabolic environment for microorganisms. By precisely controlling parameters such as temperature, pH, and dissolved oxygen, it enables the efficient synthesis of target products. In the dairy processing industry, traditional fermentation tanks have been widely used in the production of products such as yogurt and cheese.

[0003] Existing fermenters have poor sterilization effects during use. Often, the position of the sterilization lamps inside the fermenter is fixed, resulting in incomplete sterilization and making them inconvenient for users.

[0004] A search revealed that Chinese patent CN213680618U discloses a fermenter with a layered function. A servo motor drives a rotating shaft to rotate, which in turn drives a crossbar to rotate. The crossbar then drives a side bar to rotate, which in turn drives the ultraviolet lamp to rotate. This achieves the advantage of good sterilization effect and solves the problem that existing fermenters often have poor sterilization effect, and the position of the sterilization lamp inside the fermenter is often fixed, resulting in incomplete sterilization and inconvenience for users.

[0005] In actual use, the fermenters with the aforementioned stratification function separate the probiotics into aerobic and anaerobic probiotics. Aerobic probiotics require sufficient oxygen for metabolism during fermentation. Traditional fermenters are prone to local hypoxia due to uneven dissolved oxygen. Anaerobic probiotics need to be in full contact with the substrate to obtain nutrients and produce acid through metabolism. Traditional stirring methods are difficult to effectively disperse high-viscosity milk fat, which limits the metabolic activity of anaerobic bacteria. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a probiotic-milk fat dynamic stratified fermentation tank to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A probiotic-milk fat dynamic stratified fermentation tank includes a tank body, and an inlet and an outlet installed on the tank body, wherein a mixing component is installed on the tank body; The mixing component includes a connecting housing fixedly connected to the top of the tank. A first variable frequency motor is installed at the top of the connecting housing. A first gear for driving is fixedly connected to the output end of the first variable frequency motor. A second gear meshes with one side of the first gear. A rotating cylinder is fixedly connected to the bottom end of the second gear. The rotating cylinder passes through the connecting housing and the tank and extends into the interior of the tank. A gas delivery mechanism is installed on the tank body. Three scraper frames are fixedly connected to the outside of the rotating drum. One side of the scraper frame is arc-shaped. A first crushing plate and a second crushing plate are fixedly connected to the inside of the scraper frame. Multiple crushing holes are opened on the surface of the first and second crushing plates, and the crushing holes on the first and second crushing plates are staggered. A second variable frequency motor is fixedly connected to the top of the connecting shell. A rotating shaft is fixedly connected to the output end of the second variable frequency motor. The rotating shaft passes through the rotating drum and is rotatably connected to the inside of the rotating drum. Three arc-shaped stirring blades are fixedly connected to the outside of the rotating shaft. The stirring blades are wavy in shape.

[0008] By adopting the above technical solution, a layered stirring and mixing effect can be achieved, which helps to promote the layering during the fermentation process, thereby optimizing the distribution of dissolved oxygen and metabolites.

[0009] As a further description of the above technical solution: the gas conveying mechanism includes a first gas conveying ring fixedly connected to the inner wall of the tank, and a second gas conveying ring fixedly connected to the inner wall of the tank. The inner sides of the first and second gas conveying rings are provided with a plurality of honeycomb-shaped gas conveying holes, and the diameter of the gas conveying holes on the first gas conveying ring is smaller than the diameter of the gas conveying holes on the second gas conveying ring. A diversion pipe is connected to one side of the first and second gas conveying rings. The diversion pipe extends through the tank and into the inner side of the first and second gas conveying rings. A connecting pipe is connected to one side of the diversion pipe.

[0010] By adopting the above technical solution, suitable oxygen bubbles can be delivered to different areas, realizing the stratified regulation of oxygen supply and thus meeting the metabolic needs of different strains.

[0011] The technical effects and advantages of this utility model are as follows: 1. By setting up a mixing component, compared with the existing technology, the multiple crushing holes on the first and second crushing plates are staggered, so that the three scrapers can achieve local shearing when rotating, so that the upper liquid forms a multi-directional flow and can improve the dissolved oxygen efficiency of the upper liquid, promote aerobic probiotics. At the same time, the wavy structure of the stirring blades increases the contact area with the lower liquid, and the vortex effect generated by rotation strengthens the shearing and dispersion of the high viscosity milk fat in the lower layer, promotes the full contact between anaerobic probiotics and the substrate, and enhances their metabolic activity. 2. By setting up a gas conveying mechanism, compared with the existing technology, the smaller gas conveying holes on the first gas conveying ring can generate finer bubbles, which is suitable for the uniform mixing of the upper fermentation liquid, promotes the slow release of oxygen, maintains a micro-aerobic environment, and is suitable for the growth of aerobic probiotics. The larger gas conveying holes on the second gas conveying ring can enhance the turbulence intensity of the lower fermentation liquid and generate large bubbles, which can quickly increase the dissolved oxygen content, promote the full contact between milk fat and bacteria, accelerate the release of metabolites, and enhance the stratified fermentation effect.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] The embodiments disclosed in this application are as follows: Figure 1-6 The probiotic-milk fat dynamic stratified fermentation tank shown includes a tank body 1, and an inlet and an outlet installed on the tank body 1. A mixing component is installed on the tank body 1. The mixing assembly includes a connecting housing 2 fixedly connected to the top of the tank 1. A first variable frequency motor 3 is installed at the top of the connecting housing 2. A first gear 4 for driving is fixedly connected to the output end of the first variable frequency motor 3. A second gear 5 is meshed on one side of the first gear 4. A rotating drum 6 is fixedly connected to the bottom end of the second gear 5. The rotating drum 6 passes through the housing 2 and the tank 1 and extends into the interior of the tank 1. A gas delivery mechanism is installed on the tank body 1. Three scraper frames 7 are fixedly connected to the outside of the rotating drum 6. One side of the scraper frame 7 is arc-shaped. A first crushing plate 8 and a second crushing plate 9 are fixedly connected to the inside of the scraper frame 7. Multiple crushing holes 10 are opened on the surface of both the first crushing plate 8 and the second crushing plate 9, and the crushing holes 10 on the first crushing plate 8 and the crushing holes 10 on the second crushing plate 9 are staggered. A second variable frequency motor 11 is fixedly connected to the top of the connecting shell 2. A rotating shaft 12 is fixedly connected to the output end of the second variable frequency motor 11. The rotating shaft 12 passes through the rotating drum 6 and is rotatably connected to the inside of the rotating drum 6. Three scraper frames 7 are fixedly connected to the outside of the rotating shaft 12. The arc-shaped stirring blades 13 have a wave-like shape. The second gear 5 can drive the three scraper frames 7 to rotate and stir via the rotating drum 6. The staggered distribution of the crushing holes 10 on the first crushing plate 8 and the second crushing plate 9 can disperse the stirring resistance during stirring, making the upper liquid form a multi-directional flow. The rotating shaft 12 can drive the three stirring blades 13 to rotate, which increases the contact area between the stirring blades 13 and the substrate and generates a vortex effect, which enhances the shear dispersion of the high-viscosity milk fat in the lower layer and achieves uniform distribution of the lower fermentation substrate, so as to optimize the distribution of dissolved oxygen and metabolites during fermentation.

[0021] Reference Figure 3 and 6 As shown, the gas supply mechanism includes a first gas supply ring 14 fixedly connected to the inner wall of the tank 1, and a second gas supply ring 15 fixedly connected to the inner wall of the tank 1. Multiple honeycomb-shaped gas supply holes 16 are provided on the inner sides of both the first and second gas supply rings 14 and 15. The diameter of the gas supply holes 16 on the first gas supply ring 14 is smaller than that on the second gas supply ring 15. A diversion pipe 17 is connected to one side of both the first and second gas supply rings 14 and 15. The diversion pipe 17 extends through the tank 1 to the inner side of the first and second gas supply rings 14 and 15. A connecting pipe 18 is connected to one side of the diversion pipe 17, which can divide the gas supply into appropriately sized oxygen bubbles. The upper layer of tiny bubbles can remain in the fermentation broth for a longer period, ensuring slow oxygen release and promoting the synthesis of aerobic bacteria metabolites. The lower layer of larger bubbles rises, driving the movement of milk fat particles and promoting full contact between the lower layer of anaerobic bacteria and the substrate, thereby meeting the metabolic needs of different bacterial strains.

[0022] Working principle of this utility model: This utility model designs a probiotic-milk fat dynamic stratified fermentation tank, the specific structure of which is shown in the attached instruction manual. Figure 1-6As shown, in this technical solution, through the cooperation between various structures, when fermentation of the probiotic-inoculated milk base material is required, the base material is first transported into the tank 1 through the feed inlet. Then, the second variable frequency motor 11 is started by the external control device, and the second variable frequency motor 11 drives the rotating shaft 12 so that the rotating shaft 12 can drive multiple stirring blades 13 to slowly stir and mix the base material, so that the bacterial liquid and milk fat in the tank 1 can be evenly mixed. Then, the first variable frequency motor 3 is started, and the first variable frequency motor 3 drives the first gear 4 to rotate, so that the first gear 4 can mesh and drive the second gear 5 to rotate. Then, the second gear 5 can drive the three scraper frames 7 to rotate at high speed through the rotating drum 6. With the multiple crushing holes 10 opened on the first crushing plate 8 and the second crushing plate 9 on the scraper frame 7 being staggered, the base material can pass through the first crushing plate 8 and the second crushing plate 9 in sequence during the rotation, generating collision and secondary shearing, while dispersing the stirring resistance, so that the upper liquid forms a multi-directional flow. Then, the connecting pipe 18 is connected to the external oxygen supply equipment. The oxygen can be dispersed into the first gas supply ring 14 and the second gas supply ring 15 by the diversion pipe 17, so that the first gas supply ring 14 and the second gas supply ring 15 can supply oxygen at different positions in the tank 1. The diameter of the gas supply hole 16 on the first gas supply ring 14 is smaller than that on the second gas supply ring 15, so that the oxygen output from the first gas supply ring 14 can generate microbubbles. Microbubbles can ensure that the oxygen is released slowly, avoid local over-oxygenation and oxidative damage to the strains, and promote the synthesis of aerobic bacteria metabolites. The oxygen output from the second gas supply ring 15 can release a large number of bubbles, forming a strong convection effect. The rising bubbles drive the movement of the milk fat particles, releasing the encapsulated nutrients and promoting full contact between anaerobic bacteria and the substrate. By utilizing the effects of stratified stirring and stratified oxygen delivery, a high-shear zone with intense gas-liquid mixing and rich oxygen is formed in the upper part of tank 1, while a primary fermentation layer with localized mild shear is formed in the lower part of the tank, thus forming a dynamic stratified fermentation process.
