Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of probiotic embedding production equipment, in particular to a kind of embedding type probiotic production equipment. BACKGROUND

[0002] As a kind of active microorganism beneficial to human health, the efficacy of probiotic depends on sufficient number of live bacteria reaching the intestine, however, probiotic is easily inactivated in production, storage and through the human upper digestive tract, resulting in a significant decrease in the number of live bacteria, which seriously affects its final efficacy, therefore, microcapsule embedding technology is widely used in industry to protect probiotic, the core of this technology is to wrap a layer or more layers of wall material on the surface of probiotic bacteria through physical or chemical methods, forming a microcapsule structure with protective function.

[0003] The above production process usually includes emulsification mixing and curing crosslinking key procedures, wherein, emulsification mixing process aims to mix probiotic bacteria and wall material solution sufficiently and uniformly, to form a stable emulsion system, laying a foundation for subsequent solidification molding, however, in this stirring mixing process, in order to realize uniform dispersion of bacteria and wall material, sufficient mixing power needs to be applied;But probiotic bacteria itself is extremely fragile, traditional stirring equipment usually relies on the working principle of generating high shear force and strong turbulence to realize efficient mixing, which will cause strong local shear stress and excessive energy input in stirring area, this mechanical action will directly cause mechanical damage to probiotic cell wall, resulting in a significant increase in the mortality rate of live bacteria. Therefore, we propose a kind of embedding type probiotic production equipment.

[0004] The above content is only used to assist understanding of the technical solutions of the present application, and does not represent the acknowledgement of the above content as the closest prior art. SUMMARY

[0005] The present application aims to provide a kind of embedding type probiotic production equipment to solve the problems raised in the above background technology, in order to achieve the above purpose, the present application provides the following technical scheme: a kind of embedding type probiotic production equipment, including tank body, further comprising: Feed pipe, through and fixedly installed on the side wall of tank body, for feeding probiotic and wall material raw materials; Servo motor, fixedly installed on the bottom center outer wall of tank body, for providing mixing power; Mixing unit, arranged in the interior of tank body, for low-damage mixing of probiotic and wall material; Wherein, the mixing unit comprises: Frame stirring assembly, arranged in the internal cavity of tank body, for longitudinal and small-scale transverse feeding stirring close to the inner wall of tank body; The longitudinal mixing component, located at the center of the tank, is used for the longitudinal, small-scale transport of probiotics and wall material raw materials. The vacuum assembly consists of two parts located on the inner and outer sides of the tank, used for degassing and removing air from the mixture; An eccentric oscillating component, located inside the tank, is used to turbulently move the probiotics and wall material materials on the top layer.

[0006] Preferably, the frame-type stirring assembly includes: The central column is rotatably installed at the center of the inner wall of the tank, and the bottom end of the central column is fixedly connected to the output end of the servo motor, so as to cooperate with the driving force of the servo motor to continuously rotate inside the tank. Two sets of connecting frames are respectively set on the bottom and middle side walls of the central column. The ends of the two sets of connecting frames are fixedly connected with arc-shaped levers, which are used to stir and longitudinally transport the probiotics and wall materials near the inner wall of the tank in conjunction with the continuous rotation of the central column. Several arc-shaped bands are evenly distributed on the outer surface of the arc-shaped baffle, which are used to push the probiotics and wall material in the direction of travel of the arc-shaped baffle in a small lateral direction.

[0007] Preferably, the outer surface of the arc-shaped deflector away from the central column is in contact with the inner wall of the tank, and the arc-shaped deflector is arranged in a large-pitch spiral shape, and the arc-shaped band is arranged in an inclined shape with a higher elevation near the center of the tank.

[0008] Preferably, the vertical mixing component includes: Two sets of forward spiral belts are set on the outer wall of the central column to transport the probiotics and wall material mixture in a longitudinal, localized, small-scale manner at the center of the tank. Two sets of counter-rotating spiral belts are set on the outer wall of the central column to longitudinally transport the probiotic and wall material mixture in a small local area at the center of the tank.

[0009] Preferably, the two sets of forward spiral bands and reverse spiral bands are arranged at intervals in the vertical direction, and the spiral directions of the forward spiral bands and reverse spiral bands are opposite.

[0010] Preferably, the vacuum assembly includes: A rotating connector is rotatably mounted on the top of the central column. A vacuum pump is fixedly connected to the top of the rotating connector via a hose to provide external suction force. A connecting cavity is formed inside the arc-shaped baffle. The inner wall of the arc-shaped baffle away from the arc-shaped band has several anti-blocking grooves, which are connected to the connecting cavity to adsorb air bubbles and air in the mixture of probiotics and wall material. The hollow cavity, located inside the central column, is used in conjunction with the anti-blocking groove to extract air bubbles and air from the tank to create a slight vacuum.

[0011] Preferably, the anti-blocking groove is S-shaped, and the interior of the connecting frame is hollow, with the two ends of the internal cavity of the connecting frame respectively communicating with the hollow cavity and the connecting cavity.

[0012] Preferably, the eccentric oscillating assembly includes: A sleeve is fixedly installed on the top lower surface of the connecting frame. A movable rod is slidably installed on the inner wall of the sleeve, and a spring is fixedly connected between the top end of the movable rod and the top inner wall of the sleeve. An eccentric plate is rotatably mounted on the bottom end face of the movable rod, and is used to make circular motion around the central column as the movable rod moves. Inclined grooves, located inside the eccentric plate, are used to turbulent the mixture of probiotics and wall material as the eccentric plate moves.

[0013] Preferably, the cross-section of the eccentric plate is set in the shape of a teardrop, and the edge of the inclined groove is rounded.

[0014] Compared with the prior art, the beneficial effects of the present invention are: This invention solves the problem of bacterial cell damage and emulsion system disruption caused by high shear and strong turbulence in traditional mixing equipment by using a frame-type stirring assembly and a longitudinal mixing assembly in synergy. The frame-type stirring assembly adopts a large-area, low-linear-speed stirring method that fits against the tank wall, driving the material to undergo a smooth macroscopic circulation. At the same time, the arc-shaped band on it generates a gentle radial guiding force, pushing the material towards the center. The longitudinal mixing assembly uses opposite forward and reverse spiral bands to create complex but extremely low-shear convection in the central area of ​​the tank, effectively eliminating mixing dead zones and achieving full-area three-dimensional uniform mixing under low speed and low energy input. This ensures that the probiotics and the wall material are fully dispersed and in contact, while maximizing the protection of bacterial activity and the initially formed emulsion structure, thereby improving encapsulation efficiency and product stability.

[0015] This invention also incorporates a vacuum assembly, enabling online, in-situ degassing during the mixing process. This optimizes the mixing environment, ensuring that the vacuum point is directly located within the high-speed flowing material. The degassing efficiency is high and uniform. The S-shaped anti-blocking groove effectively extracts air bubbles and dissolved air while providing excellent anti-clogging performance, creating a slight vacuum environment inside the container. This not only removes air bubbles from the material but also reduces dissolved oxygen content, thereby minimizing oxidative stress damage to probiotics during the mixing stage. This facilitates the production of encapsulated probiotic products with high survival rates.

[0016] This invention also improves the flowability of the material at the top of the mixing tank by setting an eccentric oscillating component, further ensuring the overall uniformity of mixing. Utilizing the principle of fluid resistance difference, the teardrop-shaped eccentric plate generates spontaneous and irregular oscillation and rotation as it revolves with the main shaft. Combined with the elastic floating setting of the movable rod, it can adapt to liquid surface fluctuations and generate continuous, dynamic, and gentle disturbance force on the surface material. Its rounded corner grooves further enhance the fluid segmentation and mixing effect, prevent high-concentration or viscous materials from forming a skin on the liquid surface, promote the exchange of materials between upper and lower layers, eliminate weak mixing areas on the surface, and ensure that the probiotics and wall materials in each part of the tank can undergo a similar mixing process, thereby ensuring the uniformity of the final encapsulated product within and between batches.

Detailed Implementation

[0019] 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.

[0020] Please seeFigures 1-7 The present invention provides a technical solution: an encapsulated probiotic production device, comprising a tank 1, and further comprising: Feed pipe 2 is installed through and fixedly on the side wall of tank 1 for feeding probiotics and wall material raw materials; Servo motor 3 is fixedly installed on the outer wall of the bottom center of tank 1 to provide power for mixing and stirring; Mixing unit 4, located inside tank 1, is used for low-damage mixing and stirring of probiotics and wall materials; The mixing unit 4 includes: The frame-type mixing assembly 41 is set in the internal cavity of the tank 1 and is used to fit against the inner wall of the tank 1 for longitudinal and small-scale transverse feeding and mixing near the edge of the tank 1. The longitudinal mixing component 42 is located at the center of the tank 1 and is used for longitudinal small-scale transport of probiotics and wall material raw materials. The vacuum assembly 43 is divided into two parts and is located on the inner and outer sides of the tank 1, and is used for degassing and removing air from the mixture. An eccentric oscillating component 44 is located inside the tank 1 and is used to turbulently move the probiotics and wall material raw materials on the top layer.

[0021] The feed pipe 2 is used for the centralized and controllable delivery of probiotics and wall material raw materials, ensuring that the materials can be quantitatively and specifically added to the reaction area inside the tank 1. The outer contour of the frame-type stirring component 41 fits the inner wall of the tank 1. When rotating, it scrapes the inner wall and drives the materials near the tank wall to perform the main longitudinal and small transverse circulation movements near the edge of the tank 1, preventing the wall material from sticking to the wall and forming a macroscopic circulation. The longitudinal mixing component 42 can locally and slightly vertically transport the probiotics and wall material raw materials accumulated in the central area of ​​the tank 1, breaking the flow dead zone in the central area. It works in synergy with the flow field of the frame-type stirring component 41. The vacuum component 43 performs online degassing and removes dissolved air from the materials during the mixing process, creating a mild vacuum environment to reduce oxidation and improve the subsequent encapsulation quality. The eccentric oscillating component 44 performs asymmetrical turbulence and agitation on the top layer of relatively stationary probiotics and wall material raw material liquid surface, preventing surface crusting and promoting the overall mixing uniformity of the materials in the entire tank.

[0022] Please see Figures 3-4 The frame-type stirring assembly 41 includes: The center column 411 is rotatably installed at the center of the inner wall of the tank 1, and the bottom end of the center column 411 is fixedly connected to the output end of the servo motor 3, so as to cooperate with the driving force of the servo motor 3 to continuously rotate inside the tank 1. Two sets of connecting frames 412 are respectively set on the bottom and middle side walls of the central column 411. The ends of the two sets of connecting frames 412 are fixedly connected with arc-shaped levers 413, which are used to cooperate with the continuous rotation of the central column 411 to stir and longitudinally transport the probiotics and wall materials near the inner wall of the tank 1. Several arc-shaped bands 414 are evenly distributed on the outer surface of the arc-shaped baffle 413, which are used to push the probiotics and wall material in the direction of travel of the arc-shaped baffle 413 in a small lateral direction.

[0023] The central column 411 is rotatably mounted on the center of the inner wall of the tank 1 via a bearing, and the bottom end of the central column 411 is fixedly connected to the output end of the servo motor 3 to transmit the rotational driving force of the servo motor 3 to the entire stirring frame. The two sets of connecting frames 412 serve as rigid support skeletons to transmit the rotational motion of the central column 411 to the arc-shaped baffle 413, which is used to cooperate with the continuous rotation of the central column 411 to stir and push the probiotics and wall material in the vicinity of the inner wall of the tank 1 in a large area and low linear velocity. Due to the arc-shaped setting of its travel direction, it can drive the material to move longitudinally along the tank wall. Several arc-shaped bands 414 can generate a component force pointing towards the center of the tank 1 on the probiotics and wall material in front of the arc-shaped baffle 413 in the travel direction, and push it laterally, thereby guiding the edge material to the central area and merging with the flow field of the longitudinal mixing component 42.

[0024] The outer surface of the arc-shaped baffle 413 on the side away from the central column 411 is in contact with the inner wall of the tank 1, and the arc-shaped baffle 413 is arranged in a spiral shape with a large pitch, and the arc-shaped band 414 is arranged in an inclined shape with a high position near the center of the tank 1.

[0025] The close fit or minimal clearance between the arc-shaped baffle 413 and the inner wall of the tank 1 effectively scrapes away viscous materials adhering to the inner wall, preventing local stagnation. Furthermore, the overall curved surface of the arc-shaped baffle 413 generates a clear and continuous longitudinal conveying force on the material during rotation, leading to a large-scale vertical circulation of the material within the tank. The inclined shape of the arc-shaped belt 414 utilizes fluid dynamics principles. When the arc-shaped baffle 413 pushes the material, the inclined surface of the arc-shaped belt 414 applies a component velocity toward the center of the tank 1 to the material, effectively promoting radial mixing and preventing the material from circulating only near the tank wall.

[0026] Please see Figures 2-3 The vertical mixing component 42 includes: Two sets of forward spiral belts 421 are set on the outer wall of the central column 411 for longitudinal local small-scale transport of the probiotic and wall material mixture at the center of the tank 1. Two sets of reverse spiral belts 422 are set on the outer wall of the central column 411 for longitudinal local small-scale transport of the probiotic and wall material mixture at the center of the tank 1.

[0027] When the central column 411 rotates, the two sets of reverse spiral belts 422 and the two sets of forward spiral belts 421 can locally and in a small range longitudinally transport the probiotic and wall material mixture in the middle. The forward spiral belts 421 and the reverse spiral belts 422 work together to create complex and gentle vertical convection in the central area of ​​the tank 1, effectively dispersing and mixing the materials.

[0028] Two sets of forward spiral bands 421 and reverse spiral bands 422 are arranged at intervals in the vertical direction, and the spiral directions of the forward spiral bands 421 and reverse spiral bands 422 are opposite.

[0029] The opposite spiral direction setting can generate local longitudinal flow at multiple height levels in the central region, making the mixing effect more uniform and thorough. It ensures that under the single rotation direction of the central column 411, adjacent spiral bands can generate axial thrust in opposite directions, thereby forming vertical shearing and convection within the limited central space and effectively eliminating axial mixing dead angles.

[0030] Figures 1-3 as well as Figure 6 The vacuum assembly 43 includes: Rotary connector 431 is rotatably mounted on the top of central column 411. Vacuum pump 433 is fixedly connected to the top of rotary connector 431 via hose 432 to provide external suction force. The connecting cavity 435 is opened inside the arc-shaped baffle 413. The inner wall of the arc-shaped baffle 413 away from the arc-shaped band 414 is provided with several anti-blocking grooves 436. The several anti-blocking grooves 436 are connected to the connecting cavity 435 and are used to adsorb air bubbles and air in the mixture of probiotics and wall material. The hollow cavity 434 is located inside the central column 411 and is used in conjunction with the anti-blocking groove 436 to extract air bubbles and air from the tank 1 to form a slight vacuum.

[0031] The rotating connector 431 is used to achieve a dynamic sealing connection between the rotating central column 411 and the external fixed vacuum pipeline. The connecting cavity 435 serves as a distribution chamber for vacuum pumping inside the stirring component. Several anti-blocking grooves 436 are connected to the internal connecting cavity 435 to act as vacuum suction ports, directly adsorbing air bubbles and entrained air in the mixture of probiotics and wall materials flowing near the arc-shaped baffle 413. The hollow cavity 434 continuously extracts air bubbles and air precipitated from the material inside the tank 1 to the outside, thereby forming and maintaining a slight vacuum environment inside the tank.

[0032] The anti-blocking groove 436 is S-shaped, and the interior of the connecting frame 412 is hollow. The two ends of the internal cavity of the connecting frame 412 are respectively connected to the hollow cavity 434 and the connecting cavity 435.

[0033] The shape of the anti-blocking groove 436 can effectively increase the gas entry path, while reducing the risk of solid or high-viscosity materials directly clogging the groove opening. It has self-cleaning potential, and the interior of the connecting frame 412 is hollow, forming a complete and closed vacuum pumping channel from the anti-blocking groove 436 through the connecting cavity 435, the internal cavity of the connecting frame 412 to the hollow cavity 434 of the central column 411, ensuring that the vacuum effect can be effectively transmitted to the end of the stirring component.

[0034] Please see Figure 7 The eccentric oscillating component 44 includes: Sleeve 441 is fixedly installed on the top lower surface of connecting frame 412. A movable rod 442 is slidably installed on the inner wall of sleeve 441. A spring 443 is fixedly connected between the top end of movable rod 442 and the top inner wall of sleeve 441. An eccentric plate 444 is rotatably mounted on the bottom end face of the movable rod 442, and is used to make circular motion around the central column 411 with the movable rod 442. The inclined groove 445, located inside the eccentric plate 444, is used to turbulent the mixture of probiotics and wall material as the eccentric plate 444 moves.

[0035] Sleeve 441 allows movable rod 442 to slide axially within a limited range, while spring 443 provides downward elastic support for movable rod 442 and allows it to float up and down with force. Eccentric plate 444 can rotate freely around its mounting point. When movable rod 442 moves in a circle around central column 411, its asymmetrical shape generates irregular disturbance force on the top layer material it passes through. Inclined chute 445 can further divide and disturb the liquid layer flowing over its surface when eccentric plate 444 moves, enhancing the mixing effect of surface material.

[0036] The cross-section of the eccentric plate 444 is set in the shape of a water droplet, and the edge of the inclined groove 445 is rounded.

[0037] When the eccentric plate 444 moves in the mixture of probiotics and wall material, the different fluid resistance on both sides makes it easier to induce a slight sway or rotation, thereby dynamically changing its turbulence pattern. In addition, the rounded corners at the edge of the inclined groove 445 can prevent sharp edges from cutting and damaging the fragile probiotic cells or the already formed preliminary encapsulation structure, ensuring the gentleness of the turbulence process.

[0038] Working principle: The servo motor 3 is started, which drives the central column 411 to rotate stably inside the tank 1. In conjunction with the connecting frame 412, the arc-shaped baffle 413 is rotated. Since the outer surface of the arc-shaped baffle 413 away from the central column 411 is in close contact with the inner wall of the tank 1, and its whole is in the shape of a large pitch spiral, the arc-shaped baffle 413 can effectively scrape off the material attached to the tank wall during the rotation process, and promote the probiotics and wall material mixture in the vicinity of the tank wall to make macroscopic circulation movement in the up and down direction along the inner wall of the tank 1, forming the main flow field inside the tank. At the same time, as the arc-shaped strips 414 evenly distributed on the outer surface of the arc-shaped baffle 413 move with the arc-shaped baffle 413, they will generate a component force on the material in front pointing towards the center of the tank 1, thereby pushing the material in the edge area towards the center area of ​​the tank 1 in a small and continuous manner, promoting radial mixing. In the central region of tank 1, two sets of forward spiral belts 421 and two sets of reverse spiral belts 422 are arranged vertically at intervals. The forward spiral belts 421 and reverse spiral belts 422 will apply axial thrust in opposite directions to the material in the central region, forming a relatively mild vertical convection and shear in the center of tank 1, thereby efficiently dispersing and mixing the material accumulated here, eliminating dead flow zones, and working in conjunction with the macroscopic circulating flow field formed by the frame stirring assembly 41 to achieve three-dimensional uniform mixing of the material in the entire tank. During this gentle mixing process, the vacuum pump 433 is activated, and the suction force is transmitted to the hollow cavity 434 inside the central column 411 through the hose 432 and the rotating connector 431. The suction force then passes through the hollow cavity inside the hollow connecting frame 412 and reaches the connecting cavity 435 opened inside the arc-shaped baffle 413. Finally, it is released from several S-shaped anti-blocking grooves 436 opened on the inner side wall of the arc-shaped baffle 413. Since these anti-blocking grooves 436 are directly immersed in the flowing material, they adsorb and remove air bubbles and dissolved air entrained or dissolved in the mixture online, creating and maintaining a slight vacuum environment inside the tank 1, which helps to reduce oxidative damage to probiotics and improve the subsequent encapsulation quality. Meanwhile, the eccentric plate 444, which is rotatably mounted at the bottom of the movable rod 442, moves in a circular motion with the central column 411. Since the cross-section of the eccentric plate 444 is teardrop-shaped, the resistance on both sides is uneven when it moves in the liquid, which will spontaneously produce slight swaying and rotation. At the same time, the movable rod 442 can slide in the sleeve 441 and is provided with elastic support by the spring 443, so that the eccentric plate 444 can adapt to the fluctuation of the liquid surface. The inclined groove 445 with rounded edges opened inside the eccentric plate 444 can further divide and disturb the material on the top layer during its irregular movement, effectively preventing the liquid surface from forming a skin and promoting the exchange between the surface and lower layers of material, thus ensuring the overall uniformity of mixing.
