Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of embedding probiotic production equipment, in particular to a probiotic crystal ball production device and probiotic crystal ball. BACKGROUND

[0002] Probiotics are a class of active microorganisms that are beneficial to human health when ingested in sufficient quantities. However, due to the high sensitivity of probiotic bacteria to the external environment, problems such as low survival rate or poor activity often occur during production, storage and consumption, which is not conducive to the exertion of their probiotic effects. Probiotic crystal balls are probiotics treated by embedding technology. Traditional extrusion embedding technology has some significant defects in actual production and use. The so-called extrusion method is to uniformly disperse probiotics in a polysaccharide solution such as sodium alginate or a polysaccharide and protein complex solution to form a colloidal mixture. The mixture is dropped into a fixing solution (such as a calcium chloride solution) through a titration tool. The Na + of the alginate is replaced by Ca 2+ and hardened to form particles. The probiotic crystal balls prepared by the extrusion method have a large particle size, resulting in poor uniformity, irregular shape, slow crystal ball formation speed and low yield. The existing equipment has a high risk of contamination by miscellaneous bacteria and is difficult to produce on a large scale.

[0003] Based on the above, the present application provides a probiotic crystal ball production device to ensure the cleanliness and large-scale production of the probiotic crystal ball production process, effectively improving the production efficiency and roundness of the crystal ball. SUMMARY

[0016] Optionally, the spiral generating device comprises a rotating shaft rotatably arranged on the second tank, the second tank being provided with a driving motor connected to the rotating shaft in a power manner, the second tank further comprising a rotating disc connected to the rotating shaft, and the rotating disc being provided with a plurality of paddles.

[0017] Optionally, each paddle is arranged around an axis of the rotating shaft, and each paddle is arranged in an arc shape.

[0018] Optionally, the separation device comprises a separation box, the separation box being provided with a screening plate in an inclined manner, an upper side of the separation box being connected to the discharge pipe along a height direction of the separation box, the separation box on a lower side of the screening plate being provided with a liquid discharge pipe, the liquid discharge pipe being connected to the backflow pipe, and the separation box being further provided with a discharge groove, a feeding end of the screening plate being connected to the discharge pipe along a flow direction of the crystal balls, and the discharge groove being located at a discharge end of the screening plate.

[0019] Correspondingly, the application further discloses a probiotic crystal ball produced by the production device.

[0020] Compared with the prior art, the application has the following beneficial effects:

[0021] The application comprises a storage tank and a titration pumping module, the inlet end of the titration pumping module is communicated with the storage tank, the production device further comprises a first tank body and a second tank body, the upper and lower sides of the first tank body are respectively provided with a feeding port and a discharging port, the outlet end of the titration pumping module extends into the first tank body through the feeding port; the first tank body is further provided with a liquid supplementing pipe for supplementing the stationary liquid; the top of the second tank body is provided with a feeding pipe, and the bottom of the second tank body is provided with a discharging pipe, the feeding pipe is connected with the discharging port; the second tank body is provided with a spiral generating device for generating spiral water flow; the discharging pipe is further connected with a separation device;

[0022] In use, the titration pumping module draws out the colloidal solution in the storage tank and sends it into the first tank body, in the first tank body, due to the surface tension of the colloid, the high viscosity characteristics of the colloid and the like, the colloid will drop drop by drop in the form of droplets, the droplets are separated from each other, the droplets falling into the stationary liquid will displace the calcium ions in the stationary liquid and thus realize the preliminary surface hardening, the droplets after the skin hardening will enter the second tank body with the stationary liquid through the feeding pipe, in the second tank body, the spiral generating device will drive the stationary liquid to form a spiral water flow when it works, at the same time, the spiral water flow is continuously discharged from the discharging pipe at the bottom, the droplets entering the second tank body will rotate and spin under the action of intermolecular force, spiral water flow and centrifugal force; so as to gradually realize the rounding of the droplets;

[0023] In the second tank body, the droplets will continue to contact with the stationary liquid and further interact with the calcium ions, in the above process, the droplets will gradually realize the overall hardening to form crystal balls, in the above process, the weight of the gradually hardened droplets will gradually increase, and thus gradually sink, and in the sinking process, the rotation and spinning will continue to shape the droplets, the crystal balls after hardening enter the separation device with the stationary liquid from the discharging pipe, in the separation device, the crystal balls are separated from the stationary liquid, so as to realize the collection of the crystal balls;

[0024] Compared with the prior art, first, the hardening process of the droplets in the application is divided into two steps and is completed in the first tank body and the second tank body respectively, wherein the primary hardening in the first tank body is mainly to harden the surface layer of the droplets, so as to form a protective film, limit the flowability of the glue liquid, avoid the rupture of the glue liquid due to rotation and spinning in the second tank body, and improve the forming rate and output rate of the crystal balls;

[0025] Since the crystal ball takes the glue liquid as the raw material, it has high fluidity, and the protective film formed by one-time hardening has limited strength, so it cannot be subjected to too much force during the rounding process. The traditional devices such as the rounding plate directly acting on the rounded object cannot be used. The spiral flow is formed in the second tank body by the spiral generating device, so that the liquid droplets are driven and centrifuged by the water flow to realize self-rotation and rotation, and the liquid droplets are gradually hardened into crystal balls. Therefore, the colloid fluidity will gradually decrease, and the plastic deformation will gradually increase, so that the rounding is realized in the process of continuous rotation, that is, the continuous rounding and shaping of the crystal ball is realized by the rotating spiral water flow.

[0026] Secondly, due to the continuous replacement of the colloid droplets and calcium ions, the local calcium ion content in the fixing liquid will gradually decrease. In the technical solution described in the application, the spiral water flow will be continuously mixed in the process of continuous rotation, so as to realize the redistribution of calcium ions and ensure the balance of calcium ion concentration between different regions, thereby ensuring the synchronization of the secondary hardening process of each crystal ball, and further ensuring the consistency of the products at the outlet end.

[0027] Finally, the spiral water flow can drive the liquid droplets to make a spiral motion downward in the second tank body, thereby prolonging the residence time of the liquid droplets in the second tank body as much as possible under the condition of limited height of the second tank body, realizing sufficient contact and replacement of the liquid droplets and calcium ions, and ensuring that the liquid droplets can be completely hardened to form crystal balls in the second tank body.

[0028] The probiotic crystal ball production device provided by the application is connected by pipelines and can be cleaned before and after production, effectively avoiding bacterial contamination during production. At the same time, the titration nozzle of the application can be provided with several titration nozzles. When a disc-shaped titration disc is used, the bottom surface of the titration disc can be arranged with titration nozzles. By replacing titration discs of different sizes, the size of the arrangement area of the titration nozzles can be controlled, effectively improving the production efficiency and realizing large-scale production.

[0045] A feeding port is arranged at the top of the storage tank 1 to realize the addition of raw materials; a discharge port is arranged at the bottom of the storage tank 1, the titration pumping module comprises a feeding pump 9 and a titration tube 10, wherein the feeding pump 9 is preferably a screw pump or a rotor pump, the inlet end of the feeding pump 9 is connected with the discharge port at the bottom of the storage tank 1 through a feeding pipe 11, and the outlet end of the feeding pump 9 is connected with one end of the titration tube 10;

[0046] The crystal ball production device further comprises a first tank body 2, the upper part or top of the first tank body 2 is further provided with a feeding port 3, the outlet end of the titration tube 10 extends into the first tank body 2 through the feeding port 3, and the end of the titration tube 10 located in the first tank body 2 is further provided with a plurality of titration nozzles 101, the outlets of the titration nozzles 101 are arranged in a vertical downward direction to facilitate the liquid drops to directly drop into the first tank body 2.

[0047] The titration nozzle 101 is in a cylindrical structure as a whole, and is provided with a channel for the flow of glue along the axial direction, the channel is in a cylindrical shape as a whole, the inner diameter of the channel is 2-5mm, and the caliber of the channel is determined according to the size of the crystal ball; the surface tension and viscosity of the glue are relatively high, and when the glue passes through the narrow channel, the glue will be self-separated into liquid drops at the outlet end of the titration nozzle.

[0048] Further, the burette 10 located in the first tank 2 is arranged in a ring shape, a spiral line shape, a disc shape or a W shape, and the specific shape can be set as required. A plurality of burette nozzles 101 are arranged on the bottom surface of the burette 10.

[0049] It should be noted that a titration disc can also be arranged in the first tank. The titration disc can be in a disc shape or a square shape. The titration disc is in communication with the burette, and each burette nozzle is connected to the titration disc, so that the glue solution is distributed again by the titration disc.

[0050] The titration disc can be arranged in a limited space to arrange more burette nozzles, so that more liquid drops are formed at the same time, which is beneficial to improve the production efficiency of the crystal ball.

[0051] Meanwhile, a support column 15 is arranged in the first tank 2. The top of the support column 15 is connected to the top cover of the first tank 2. A spiral plate 16 is arranged on the outer surface of the support column 15. The outer side of the spiral plate 16 is tightly attached to the inner wall of the first tank 2. Meanwhile, a discharge port 4 is arranged at the bottom of the first tank 2. The discharge port 4 is in communication with the outlet end of the spiral plate 16. The top of the spiral plate 16 is the inlet end thereof. Each burette 10 is opposite to the inlet end of the spiral plate 16.

[0052] The spiral plate 16 can prolong the residence time of the liquid drops in the first tank 2, so as to ensure the structural strength of the protective film on the surface of the liquid drops and avoid the rupture of the liquid drops in the second tank 6. On the other hand, since there is no stirring device in the first tank 2, the fixing liquid flows around the spiral plate 16 and enters the second tank 6. Due to the driving of the fixing liquid and the gravity of the liquid drops, the liquid drops roll on the surface of the spiral plate 16, so as to realize the preliminary rounding of the shape of the liquid drops.

[0053] Finally, the spiral plate 16 can also buffer the liquid drops in the early stage of hardening, so as to avoid the tearing of the liquid drops by the fixing liquid flowing into the second tank 6 from the first tank 2 at a too high speed, and improve the yield of the crystal ball.

[0054] Further, there is a space between the burette nozzle 101 and the inlet end of the spiral plate 16 in the vertical direction. The space is a cavity structure, which is a first hardening area 17. No component is arranged in the first hardening area 17.

[0055] The above arrangement can form a relatively static water flow area in the upper part of the first tank 2. Since the surface of the just titrated liquid drops has no hardening protective layer, the relatively static environment can avoid the tearing of the liquid drops by the disturbance of the solution flow after the titrated liquid drops enter the area, so as to improve the yield of the crystal ball.

[0056] The production device further comprises a second tank body 6, which is provided with a feeding pipe 7 at the top, the inlet end of the feeding pipe 7 is communicated with the discharge port 4 at the bottom of the first tank body 2, so that the first tank body 2 is communicated with the second tank body 6 through the feeding pipe 7;

[0057] The second tank body 6 is further provided with a spiral generating device, wherein the spiral generating device comprises a rotating shaft 18 and a driving motor 19, the driving motor 19 is arranged at the top of the second tank body 6, the rotating shaft 18 is rotatably arranged on the second tank body 6 through a thrust ball bearing, along the axis of the rotating shaft 18, the upper end of the rotating shaft 18 is located outside the second tank body 6, and the lower end of the rotating shaft 18 is located inside the second tank body 6, wherein the end located outside the second tank body 6 is connected with the driving motor 19 through a driving gear, and the end located inside the second tank body 6 is provided with a rotating disc 20;

[0058] Further, the bottom surface of the rotating disc 20 is a plane, and the top surface is a conical structure, the rotating disc 20 is coaxially connected with the rotating shaft 18, and a plurality of paddles 21 are further arranged on the rotating disc 20, the paddles 21 are uniformly arranged around the axis of the rotating disc 20, and the bottom surfaces of the paddles 21 are integrally connected with the conical top surface of the rotating disc 20 respectively;

[0059] When viewed along the axial direction of the rotating shaft 18, each of the paddles 21 is arranged in an arc shape;

[0060] The bottom of the second tank body 6 is further provided with a discharge pipe 8 for discharging the fixing liquid and the crystal ball;

[0061] In use, the rotating disc 20 is driven to rotate by the driving motor 19, the paddles 21 located on the top surface of the rotating disc 20 drive the fixing liquid stored in the second tank body 6 to rotate and form a spiral water flow, and at the same time, the fixing liquid with a low content of calcium ions is discharged from the discharge pipe 8 together with the crystal ball;

[0062] The rotating disc 20 and the paddles 21 can form a stable spiral water flow in the second tank body 6, and the rotation speed of the spiral water flow can be adjusted by adjusting the rotation speed of the rotating disc 20 and the number of the paddles 21, so as to realize accurate control of the hardening process;

[0063] Further, the production device further comprises a separation device, the separation device comprises a separation box 22, the top of the separation box 22 is open, and a collecting cover in a conical structure is integrally connected to the bottom of the separation box 22, and a liquid discharge pipe 25 is connected to the bottom of the collecting cover;

[0064] Meanwhile, a screening plate 23 is arranged in the middle of the separation tank 22, and a plurality of screening holes are arranged on the screening plate 23, and it is to be noted that the diameter of the screening holes is not greater than 30% of the diameter of the crystal ball, so as to ensure that only the stationary liquid can pass through the screening holes and enter the lower side of the screening plate 23;

[0065] The upper side space of the screening plate 23 is connected with the discharge pipe 8, and meanwhile, a discharge groove 24 is arranged on the upper side of the separation tank 22, and along the flow direction of the crystal ball, the discharge pipe 8 is arranged at the feeding end of the screening plate 23, and the discharge groove 24 is arranged at the discharging end of the screening plate 23;

[0066] Further, the screening plate 23 is arranged in an inclined manner, and the inclination angle is determined according to actual needs, and one end of the screening plate 23 towards the discharge pipe 8 is upwarping, and one end of the screening plate 23 towards the discharge groove 24 is sunken, so as to form a structure feature that the inlet end is high and the outlet end is low, and the flow separation of the material is realized by using the self-weight of the material;

[0067] Meanwhile, a guide plate 26 is arranged at the inlet end of the discharge groove 24, and the guide plate 26 is in an eight-shaped structure, and the guide plate 26 is connected with the discharge groove 24, so as to guide the crystal ball to flow to one side of the discharge groove 24;

[0068] It is to be noted that the discharge groove 24 can also adopt a closed pipe structure, and the outlet end of the discharge groove 24 is connected with a sorting device, so as to realize the fully-closed production of the crystal ball and improve the cleanliness of the product.

[0069] Further, the top of the separation tank 22 can also be provided with a cover plate, but in order to ensure the separation effect and avoid the stationary liquid from entering the discharge groove 24, the length of the separation tank 22 needs to be increased, and the screening plate 23 is also lengthened, so as to form enough separation space in the separation tank 22.

[0070] Further, the production device also comprises a stationary liquid storage tank 12, and the stationary liquid storage tank 12 is communicated with the liquid discharge pipe 25 at the bottom of the separation tank 22 through a backflow pipe 13, and a corresponding backflow pump can be additionally arranged on the backflow pipe 13;

[0071] Meanwhile, a liquid supplement pipe 5 is arranged on the first tank body 2, and the inlet end of the liquid supplement pipe 5 is communicated with the stationary liquid storage tank 12 through a circulating pump 14; a calcium salt supplement pipe, a liquid level sensor and a sensor for detecting the concentration of calcium salt are arranged on the stationary liquid storage tank 12;

[0072] Meanwhile, an adjusting valve for controlling the on-off state of the liquid supplement pipe 5 is arranged on the liquid supplement pipe 5;

[0073] The production device further comprises a controller, which comprises an industrial computer and a PLC, wherein the industrial computer is connected with the PLC through a data bus, and the PLC is connected with each automatic control element such as the feeding pump 9, the driving motor 19 and the adjusting valve, so as to realize the control and adjustment of the whole device.

[0074] By arranging the fixed liquid storage tank 12, the reflux pipe 13 and the liquid supplement pipe 5, a closed circulation loop is formed in the whole system, which starts from the fixed liquid storage tank 12, passes through the first tank body 2, the second tank body 6 and the separation box 22 and then enters the fixed liquid storage tank 12 again.

[0075] During the flowing process of the fixed liquid, on one hand, the fixed liquid can drive the liquid drops and the crystal balls to transfer between different devices, so as to realize the continuous production of the crystal balls. The above-mentioned mode ingeniously uses the flowing of the fixed liquid and does not need to increase additional equipment, which is beneficial to simplify the structure of the whole device. On the other hand, during the actual production process, with the continuous calcium ion exchange, the calcium ion content in the fixed liquid is continuously reduced. The circulation system formed by the fixed liquid storage tank 12 and various pipes can form a complete fixed liquid circulation system in the first tank body 2 and the second tank body 6, so as to timely discharge the solution with low calcium ion content and introduce the fixed liquid with high calcium ion content, so as to ensure the stability of the calcium ion content in the first tank body 2 and the second tank body 6, so as to ensure the continuous and stable calcium ion exchange hardening process and the continuous and stable production of the crystal balls, and improve the production efficiency.

[0076] Secondly, in the above-mentioned circulation pipeline, the distribution concentration of the fixed liquid is that the calcium ion concentration in the first tank body 2 is the highest, and the calcium ion concentration in the second tank body 6 is the second. The above-mentioned concentrations correspond to the two hardening processes of the liquid drops. During the first hardening process, the higher calcium ion concentration can effectively improve the hardening efficiency, so as to form the required protective film in a limited time. Although the calcium ion concentration in the second tank body 6 is lower, the spiral water flow can effectively prolong the residence time of the fixed liquid in the second tank body 6.

[0077] Through the distribution of the above-mentioned calcium ion concentration, the smooth progress of the whole exchange hardening process can be effectively ensured, and the smooth progress of the crystal ball production process can be ensured.

[0078] Further, a branch can be further arranged on the liquid supplement pipe 5, and an adjusting valve is arranged on the branch. The branch directly communicates with the second tank body 6.

[0079] When the calcium ion concentration in the second tank body 6 is abnormally reduced, the above-mentioned branch can be used to urgently supplement the fixed liquid with high concentration to the second tank body 6, so as to ensure the stability of the calcium ion concentration in the second tank body 6, and further ensure the production rate of the crystal balls.

[0080] When the production device is used, the colloid solution stored in the discharge tank is extracted by the feeding pump and sent into the first tank body. In the first tank body, due to the surface tension of the colloid and the high viscosity characteristics of the colloid, the colloid will be separated into individual droplets when passing through the titration nozzle 101, and the droplets falling into the fixing liquid will interact with the calcium ions in the fixing liquid to achieve preliminary surface hardening. Part of the hardened droplets will enter the second tank body with the fixing liquid through the feeding pipe. In the second tank body, the driving motor drives the rotating disc to rotate, thereby forming a spiral water flow, and the spiral water flow will be continuously discharged from the bottom discharge pipe into the second tank body. The semi-finished crystal ball in the second tank body will rotate under the action of the centrifugal force and the spiral water flow, and will also rotate along the inner wall of the second tank body. Thus, the droplets are gradually rounded during the rotation and rotation processes.

[0081] In the second tank body, the droplets will continue to contact with the fixing liquid and further interact with the calcium ions. In the above process, the droplets will gradually harden to form crystal balls. In the above process, the weight of the gradually hardened droplets will gradually increase, and then gradually sink. During the sinking process, the rotation and rotation will continue to shape the droplets, and the hardened crystal balls will enter the separation device with the fixing liquid from the discharge pipe. In the separation device, the crystal balls are separated from the fixing liquid, thereby realizing the recovery of the crystal balls.

[0082] It should be noted that the raw materials used in the preparation of the crystal balls in the present application include colloid and fixing liquid. The above-mentioned colloid is prepared by adding 2% sodium alginate into RO water and stirring to dissolve, heating to 90-95℃ and keeping for 20-30 min, cooling to room temperature, then adding probiotic solution and stirring to mix uniformly, and standing for 30 min until the bubbles disappear.

[0083] The fixing liquid is prepared by adding 1% calcium chloride into RO water and stirring to dissolve, heating to 90℃ and keeping for 10-15 min, and cooling to room temperature.

[0084] Compared with the prior art, first, the hardening process of the droplets is separated into two times and completed in the first tank body and the second tank body, respectively. The first hardening in the first tank body is mainly to harden the surface layer of the droplets, thereby forming a protective film to limit the flowability of the colloid and avoid its rupture in the second tank body due to rotation and rotation, thereby improving the forming rate and output rate of the crystal balls.

[0085] Since the crystal ball uses glue solution as raw material, it has high fluidity, and the protective film formed by one-time hardening has priority in strength, so it cannot be subjected to excessive force during rounding. Traditional devices such as rounding plates that directly act on the rounded object cannot be used. The present application forms a spiral water flow in the second tank body through the spiral generating device, thereby controlling the rotation and rotation of the droplet through the driving of the water flow and the centrifugal force. At the same time, during the rotation process, the droplet will gradually harden into a crystal ball, so the colloid fluidity will gradually decrease, and the plastic deformation will gradually increase, thereby realizing rounding in the process of continuous rotation, that is, the spiral water flow is rotated to realize the continuous rounding and shaping of the crystal ball.

[0086] Secondly, due to the continuous exchange of droplets and calcium ions, the calcium ion content in the fixing liquid will gradually decrease. In the technical solution described in the present application, the spiral water flow will continuously mix during continuous rotation, thereby realizing the redistribution of calcium ions and ensuring the balance of calcium ion concentration between different regions, thereby ensuring the synchronization of the secondary hardening process of each crystal ball, and further ensuring the consistency of the product at the outlet end.

[0087] Finally, the spiral water flow can drive the droplets to make a spiral motion downward in the second tank body, thereby prolonging the residence time of the droplets in the second tank body as much as possible under the condition of limited height of the second tank body, realizing sufficient contact and replacement of the droplets and calcium ions, and ensuring that the droplets can be completely hardened into crystal balls in the second tank body.

[0088] The above is only the preferred embodiment of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation using the content of the present application specification and drawings, or direct or indirect application in other related technical fields, is also included in the patent protection scope of the present application.
