Description

Technical Field

[0001] This invention relates to the field of dissolving equipment technology, and in particular to a lactic acid bacteria dissolving equipment and preparation process for regulating intestinal flora. Background Technology

[0002] Lactic acid bacteria, as probiotics, can regulate the balance of intestinal flora, improve intestinal barrier function, and inhibit the growth of harmful bacteria, thus directly affecting intestinal health. Therefore, they are widely used as probiotics in beverages for conditioning the intestines.

[0003] Currently, in the industrial production of beverages, the addition of microbial agents mainly includes: liquid fermentation agent addition method and freeze-dried microbial powder addition method. Both methods involve adding microbial powder to the beverage according to a predetermined ratio, and then mixing and stirring to make the microbial powder evenly mixed into the beverage.

[0004] Currently, the mixing of microbial agents with beverages often involves directly adding the microbial agents and then stirring. This method easily causes the microbial agents to clump together, affecting the uniformity of the mixture. Furthermore, due to the characteristics of microbial powder, it is not suitable for rapid and vigorous stirring, resulting in low mixing efficiency. Summary of the Invention

[0005] The purpose of this invention is to solve the above-mentioned problems by providing a lactic acid bacteria dissolving device and preparation process for regulating intestinal flora.

[0006] To achieve the above objectives, the present invention provides a lactic acid bacteria lysis device for regulating intestinal flora, comprising a stirring chamber, wherein the stirring chamber is equipped with a liquid inlet pipe, and further comprising:

[0007] The bacterial liquid chamber is located at the top of the stirring chamber. The bacterial liquid chamber is equipped with a liquid addition assembly, which includes a piston cylinder, a piston 1 disposed inside the piston cylinder, and a disturbance rod connected to the piston 1. The disturbance rod is provided with an internal channel communicating with the piston cylinder. The internal channel is equipped with a one-way valve 1. The piston cylinder is provided with a suction pipe communicating with the bacterial liquid chamber. The suction pipe is equipped with a one-way valve 2.

[0008] The reciprocating rod is connected to the piston and is used to drive the piston to reciprocate axially.

[0009] The mixing chamber is located at the bottom of the bacterial culture chamber;

[0010] The mixing chamber is connected to the lower end of the inlet pipe and the disturbance rod.

[0011] Furthermore, the reciprocating rod is connected to a reciprocating drive component, and the reciprocating drive frequency of the reciprocating drive component is proportional to the liquid pressure in the inlet pipe.

[0012] Furthermore, the reciprocating drive component is either a pneumatic cylinder or a hydraulic cylinder, and a reversing valve is configured on the inlet pipe. The reversing valve is located on the control path of the reciprocating drive component, and the switching frequency of the reversing valve is proportional to the liquid pressure in the inlet pipe.

[0013] Furthermore, the reversing valve includes a flange pipe, a driving component disposed on the flange pipe, and a valve body drivenly connected to the driving component. The driving component includes a piston rod guided on the side wall of the flange pipe, a cylinder disposed parallel to the piston rod, a second piston disposed in the cylinder, a driving rod guided at the end of the cylinder, and a second elastic element disposed between the second piston and the cylinder.

[0014] The piston rod is equipped with a second liquid passage, the piston rod is provided with a fourth liquid passage, and the end of the cylinder away from the piston rod is provided with a third liquid passage. The flow area of ​​the second liquid passage is larger than the flow area of ​​the fourth liquid passage but smaller than the flow area of ​​the third liquid passage. The drive rod is connected to the valve body.

[0015] Furthermore, the second elastic element is a compression spring disposed on the side of the piston away from the piston rod.

[0016] Furthermore, the other end of the third liquid passage is connected to a flange pipe, which is located at the end of the inlet pipe. The flange pipe has a constriction section inside, which is located between the third liquid passage and the piston rod.

[0017] Furthermore, a rigid cylinder is provided on the piston two, the drive rod is guided and cooperated with the rigid cylinder, a rigid plate is provided at the end of the drive rod that extends into the rigid cylinder, and compression springs three are provided on both sides of the rigid plate.

[0018] Furthermore, the reciprocating drive is located at the top of the bacterial liquid chamber, and the reciprocating rod connects the telescopic rod of the reciprocating drive and the piston.

[0019] Furthermore, located below the mixing chamber, a flow equalization component is also provided inside the stirring chamber. The flow equalization component includes:

[0020] Liquid tank one is located directly below the mixing chamber;

[0021] Multiple liquid tanks 2 are arranged around liquid tank 1 at intervals and interconnected, and are connected to liquid tank 1 through liquid pipe 1. Multiple micropores are provided at the bottom.

[0022] Furthermore, this application provides a process for preparing lactic acid bacteria for regulating intestinal flora by dissolving them, using any of the dissolving devices described above, and including the following steps:

[0023] Step 1: Mix the lactic acid bacteria powder according to the predetermined ratio to form a bacterial solution, and add the bacterial solution into the bacterial solution chamber;

[0024] Step 2: Pump the solution at a predetermined pressure into the inlet pipe. The solution flows into the mixing chamber through the inlet pipe.

[0025] Step 3: The reciprocating rod drives the piston to reciprocate according to the pumping pressure of the solution, transporting the bacterial solution in the bacterial solution chamber to the mixing chamber, and driving the disturbance rod to agitate the solution in the mixing chamber for preliminary mixing;

[0026] Step 4: The solution in the mixing chamber flows to the stirring chamber, where it is stirred and mixed again.

[0027] The lactic acid bacteria dissolving device and preparation process for regulating intestinal flora disclosed in this invention have the following advantages compared with the prior art: the reciprocating motion of piston one, combined with one-way valve one and one-way valve two, realizes the quantitative and stable delivery of bacterial solution. At the same time, the disturbance rod moves synchronously with piston one, which can disturb the solution in the mixing chamber, promote the initial mixing of bacterial solution and solution, and effectively reduce the clumping phenomenon. The setting of the mixing chamber allows the bacterial solution and solution to be initially mixed before entering the stirring chamber for further mixing, which improves the mixing uniformity. Compared with the traditional direct stirring and mixing method, the mixing efficiency is significantly improved. Attached Figure Description

[0047] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the invention in a schematic manner, and therefore only show the components relevant to the invention.

[0048] Example 1

[0049] Please refer to Figure 1 - Figure 4 This invention provides a lactic acid bacteria dissolving device for regulating intestinal flora. As a specific embodiment, it includes a stirring chamber 1, which is equipped with a liquid inlet pipe 12, and further includes:

[0050] The bacterial liquid chamber 2 is located at the top of the stirring chamber 1. The bacterial liquid chamber 2 is equipped with a liquid addition assembly 21. The liquid addition assembly 21 includes a piston cylinder 211, a piston 212 disposed in the piston cylinder 211, and a disturbance rod 213 connected to the piston 212. The disturbance rod 213 is provided with an internal channel 2130 communicating with the piston cylinder 211. The internal channel 2130 is equipped with a one-way valve 24. The piston cylinder 211 is provided with a suction pipe 210 communicating with the bacterial liquid chamber 2. The suction pipe 210 is equipped with a one-way valve 25.

[0051] The reciprocating rod 40 is connected to the piston 212 and is used to drive the piston 212 to reciprocate along the axial direction;

[0052] Mixing chamber 22 is located at the bottom of bacterial culture chamber 2;

[0053] The mixing chamber 22 is connected to the lower end of the liquid inlet pipe 12 and the disturbance rod 213.

[0054] For details, please refer to Figure 1 - Figure 3 The specific structure of the dissolving device provided by the present invention is as follows: it includes a stirring chamber 1, a stirring motor 11 is provided at the bottom of the stirring chamber 1, the stirring motor 11 is driven and connected to a stirring shaft, the stirring chamber 1 is provided with a top cover 10, wherein the bacterial liquid chamber 2 is fixedly provided on the top cover 10, the bacterial liquid chamber 2 is provided with a liquid inlet 20, the bottom of the stirring chamber 1 is provided with a liquid outlet pipe 13, the piston cylinder 211 is provided at the bottom of the bacterial liquid chamber 2, the upper end of the piston cylinder 2 extends into the bacterial liquid chamber 2, the disturbance rod 213 is integrally provided with or threadedly connected to the piston 212, and the disturbance rod 213 and the lower end of the piston cylinder 211 are guided and sealed together.

[0055] refer to Figure 9 - Figure 12 The upper end of the piston cylinder 211 is provided with a suction pipe 210, and the lower end of the suction pipe 210 is provided with a one-way valve 25. The internal channel 2130 inside the disturbance rod 213 is coaxially arranged with the disturbance rod 213, with its lower end being open and its upper end being provided with a one-way valve 24. The specific structure of the one-way valve 24 includes: a valve passage 240 communicating with the internal channel 2130, a valve element 241 provided at the end of the valve passage 240, a spherical element 243 abutting against the valve element 241, and a compression spring applying force to the spherical element 243. 1242, at least one one-way valve three is also provided on piston one 212. One-way valve three includes a conical groove 2122 provided on the lower surface of piston one 212, a valve element three 2121 guided at the bottom of conical groove 2122, and a plurality of liquid passages one 2120 provided around valve element three 2121. Liquid passages one 2120 pass through piston one 212 and the lower end is located in conical groove 2122. The lower end of valve element three 2121 is provided with a conical element adapted to conical groove 2122, and the upper end of valve element three 2121 is provided with a limit snap ring.

[0056] The inlet pipe 12 is used to deliver a solution (i.e., the base liquid for intestinal conditioning drinks) at a predetermined pressure into the equipment. The inlet pipe 12 is connected to an external pumping device to achieve stable delivery of the solution. The bacterial solution chamber 2 is used to store pre-prepared lactic acid bacteria solution, avoiding clumping problems caused by direct addition of bacterial powder. One end of the reciprocating rod 40 is fixedly connected to the piston 212, and the other end extends to the outside of the bacterial solution chamber 2 or is connected to the drive structure. The axial reciprocating motion of the reciprocating rod 40 drives the piston 212 to reciprocate synchronously. The mixing chamber 22 is located at the bottom of the bacterial solution chamber 2. The lower end of the agitator 213 extends into the mixing chamber 22, and the end of the inlet pipe 12 is connected to the top of the mixing chamber 22. During operation, the solution is delivered into the mixing chamber 22 at a predetermined speed, and the reciprocating rod 40 is driven to reciprocate at a certain frequency according to the delivery speed, thereby driving the piston 212 to reciprocate. When the piston 212 moves upward, the valve 2121 moves downward, and the liquid passage 2120 is opened. At this time, the flow above the piston cylinder 211... The medium can flow through one-way valve three to the bottom of piston cylinder 211. When piston one 212 moves downward, both one-way valve one 24 and one-way valve two 25 are closed. Valve three 2121 is impacted by the flowing medium and enters the conical groove 2122, blocking liquid passage one 2120. One-way valve three closes, and the pressure below piston one 212 increases, squeezing ball 243 to overcome the elastic force of spring one 242. One-way valve one 24 opens, and the flowing medium enters mixing chamber 22 through disturbance rod 213. The pressure above piston one 212 decreases, thereby generating negative pressure in suction tube 210. Under the action of negative pressure, one-way valve two 25 opens, drawing bacterial liquid from bacterial liquid chamber 2 into piston cylinder 211. This process repeats, achieving the effect of pumping bacterial liquid. By utilizing the reciprocating motion of piston 212 in conjunction with check valves 24 and 25, quantitative and stable delivery of bacterial solution is achieved. Simultaneously, the disturbance rod 213 moves synchronously with piston 212, which can agitate the solution in mixing chamber 22, promote the initial mixing of bacterial solution and solution, and effectively reduce clumping. The design of mixing chamber 22 allows bacterial solution and solution to be initially mixed before entering stirring chamber 1 for further mixing, which improves the mixing uniformity. Compared with the traditional direct stirring mixing method, the mixing efficiency is significantly improved.

[0057] Furthermore, as a preferred embodiment, refer to Figure 10 , Figure 17 A disturbance plate 23 is also provided at the lower end of the disturbance rod 213. The disturbance plate 23 is provided with a threaded hole 231 connected to the lower end of the disturbance rod 213 and liquid replenishment holes evenly distributed around the threaded hole 231. The lower end of the liquid distribution hole 230 is connected to the bottom of the threaded hole 231. By setting the disturbance plate 23, the disturbance mixing effect can be improved on the one hand, and the bacterial liquid can flow out through multiple liquid distribution holes 230 after passing through the internal channel 2130, which further improves the mixing uniformity of the bacterial liquid and the solution.

[0058] As a specific implementation method, refer to Figure 9 The bottom of the mixing chamber 22 is conical, with a bottom hole 221. The flow area of ​​the bottom hole 221 is relatively small. Multiple flow equalization holes 220 are provided on the middle side wall. The flow area of ​​the multiple flow equalization holes 220 is larger than the flow area of ​​the liquid inlet pipe 12. The flow equalization holes 220 are located above the disturbance plate 23. With this arrangement, the solution entering the mixing chamber 22 through the liquid outlet pipe 13 accumulates to a certain amount before flowing out through the flow equalization holes 220. At this time, the solution can submerge the disturbance plate 23, thereby ensuring that the bacterial solution mixes with the solution in the mixing chamber 22. When the solution flows out through the multiple flow equalization holes 220 after mixing, the mixing uniformity can be further improved. After the feeding is completed, the residual solution inside the mixing chamber 22 can flow out through the bottom hole 221.

[0059] Furthermore, as a specific implementation, the reciprocating rod 40 is driven to be connected to a reciprocating drive component 4, and the reciprocating drive frequency of the reciprocating drive component 4 is proportional to the liquid pressure in the inlet pipe 12.

[0060] Specifically, it can be understood that the reciprocating drive 4 can be a linear drive structure, with its output end fixedly connected to the end of the reciprocating rod 40 away from the piston 212, thereby driving the reciprocating rod 40. A pressure detection element (such as a pressure sensor) is mounted on the inlet pipe 12. This pressure detection element is electrically connected to the control module of the reciprocating drive 4, or linked through a mechanical structure, so that when the liquid pressure inside the inlet pipe 12 changes, the reciprocating drive frequency of the reciprocating drive 4 changes synchronously. For example, when the liquid pressure inside the inlet pipe 12 increases (i.e., the pumping flow rate of the solution increases), the reciprocating frequency of the reciprocating drive 4 increases, causing the piston 212 to reciprocate faster, thereby increasing the amount of bacterial solution delivered; when the liquid pressure inside the inlet pipe 12 decreases, the reciprocating frequency of the reciprocating drive 4 decreases, and the amount of bacterial solution delivered decreases accordingly. The above method achieves dynamic matching between the bacterial solution delivery rate and the dissolving solution delivery rate, avoiding imbalance in the ratio of bacterial solution to dissolving solution due to changes in the dissolving solution flow rate, and ensuring uniform and stable concentration of the mixed solution; it eliminates the need for manual adjustment of the bacterial solution delivery rate, improves the automation level of the equipment, and adapts to the flow rate changes required under different production conditions.

[0061] Furthermore, as a specific implementation method, refer to Figure 13 - Figure 16 The reciprocating drive 4 is either a pneumatic cylinder or a hydraulic cylinder. A reversing valve 3 is configured on the inlet pipe 12. The reversing valve 3 is located on the control path of the reciprocating drive 4. The switching frequency of the reversing valve 3 is proportional to the liquid pressure in the inlet pipe 12.

[0062] As a specific implementation method, the reciprocating drive component 4 is selected from a pneumatic cylinder or a hydraulic cylinder, preferably a double-acting pneumatic cylinder; when a pneumatic cylinder is selected, its air inlet and outlet are connected to the reversing valve 3 through an air pipe; when a hydraulic cylinder is selected, its oil inlet and outlet are connected to the reversing valve 3 through an oil pipe.

[0063] Specifically, the reversing valve 3 includes a valve body 32, and the cylinder includes two ports 41 at both ends. The valve body 32 includes two ports 320 and two ports 321. The two ports 320 are connected to the two ports 41 respectively, and one port 321 is connected to the power source, while the other end of the two ports 321 is connected to the atmosphere. The switching frequency of the reversing valve 3 is controlled by the liquid pressure in the inlet pipe 12, which can be achieved through a mechanical linkage structure or an electrical control structure. When the liquid pressure in the inlet pipe 12 increases, the switching frequency of the reversing valve 3 increases, thereby increasing the reciprocating frequency of the reciprocating drive component 4, and vice versa. Through the linkage between the reversing valve 3 and the pressure in the inlet pipe 12, the adaptive adjustment of the reciprocating drive frequency is achieved, further optimizing the accuracy of the ratio matching between bacterial solution and dissolving solution. The setting of the reversing valve 3 makes the switching of the movement direction of the reciprocating drive component 4 smoother, reduces the impact during equipment operation, and extends the service life of the equipment.

[0064] refer to Figure 16 The specific structure of the valve body 32 is as follows: it includes a valve cavity 324, a valve stem 325 disposed within the valve cavity 324, and two limiting members 326 disposed at both ends of the valve cavity 324. Along the axial direction, the outer circumferential surface of the valve stem 325 is provided with annular groove 1 327, annular groove 2 328, and annular groove 329 spaced apart. The valve stem 325 has a connecting liquid passage 3250 connecting annular groove 1 327 and annular groove 329. The two interfaces 1 320 and the two interfaces 2 321 are staggered. During operation, driving the valve stem 325 to move axially can achieve the connection effect between the two interfaces 1 320 and the two interfaces 2 321. (Refer to...) Figure 16 At this point, the reversing valve 3 is in the closed state, and the two ports 321 correspond to the outer circumferential surfaces of the valve stem 325 and are in a blocked state. When the valve stem 325 is moved axially, when the valve stem 325 abuts against the right limit member 326, the annular groove 327 can connect with the left port 320 and the left port 321, and the annular groove 328 can connect the right port 320 and the right port 321. When the valve stem 325 abuts against the left limit member 326, the right port 321 connects with the annular groove 329, and the annular groove 327 connects with the left port 321, thereby connecting the left port 320 with the right port 321, and the annular groove 328 connects the right port 320 with the left port 321, achieving the switching effect.

[0065] Example 2

[0066] This invention provides a lactic acid bacteria dissolving device for regulating intestinal flora. As a specific embodiment, the reversing valve 3 includes a flange pipe 30, a driving component 31 disposed on the flange pipe 30, and a valve body 32 drivenly connected to the driving component 31. The driving component 31 includes a piston rod 310 guided and disposed on the side wall of the flange pipe 30, a cylinder disposed parallel to the piston rod 310, a second piston 312 disposed in the cylinder, a driving rod 315 guided and disposed at the end of the cylinder, and an elastic component 2 disposed between the second piston 312 and the piston cylinder 211.

[0067] The piston rod 310 is provided with a second liquid passage 311, the piston 312 is provided with a fourth liquid passage 3120, and the end of the cylinder away from the piston rod 310 is provided with a third liquid passage 314. The flow area of ​​the second liquid passage 311 is larger than the flow area of ​​the fourth liquid passage 3120 and smaller than the flow area of ​​the third liquid passage 314. The drive rod 315 is connected to the valve body 32.

[0068] For details, please refer to Figure 15 The flange pipe 30 is fixedly assembled to the end of the inlet pipe 12 via a flange connection, facilitating disassembly and maintenance. The cylinder is threadedly assembled to the side wall of the flange pipe 30. The piston rod 310 is guided and assembled to the side wall of the flange pipe 30 via a guide sleeve, and can slide radially along the flange pipe 30. One end of the piston rod 310 extends into the flange pipe 30 and contacts the liquid in the inlet pipe 12, while the other end is fixedly connected to the cylinder. The cylinder is arranged parallel to the piston rod 310, and its interior is parallel to the axis of the piston rod 310. The piston 312 slides and seals with the inner wall of the cylinder, dividing the cylinder into two chambers. The drive rod 315 is guided and assembled to the end of the cylinder away from the piston rod 310 via a guide sleeve. One end extends into the cylinder and is fixedly connected to the piston 312, while the other end extends to the outside of the cylinder and is fixedly connected to the valve body 32. The elastic element 2 is disposed between the piston 312 and the piston cylinder 211 to provide the piston 312 with a restoring force to move in the direction of the piston rod 310. A second liquid passage 311 is axially formed inside the piston rod 310. One end of the second liquid passage 311 communicates with the interior of the flange pipe 30, and the other end passes through the side wall of the piston rod 310 near the second piston 312. A fourth liquid passage 3120 is axially formed on the second piston 312, and both ends of the fourth liquid passage 3120 communicate with two chambers of the cylinder, respectively. A third liquid passage 314 is formed at the end of the cylinder away from the piston rod 310. One end of the third liquid passage 314 communicates with the chamber of the cylinder away from the piston rod 310, and the other end can communicate with an external control pipeline or other chambers. The flow area of ​​the second liquid passage 311 is larger than that of the fourth liquid passage 3120 but smaller than that of the third liquid passage 314. A groove is provided along the axis on the outer circumference of the piston rod 310, and the groove communicates with the end of the second liquid passage 311 near the flange pipe 30. Through the above arrangement, in Figure 15In the state shown, valve stem 325 is in the initial state of contact with left limiting member 326. At this time, elastic member 2 is in the energy storage state. When supplying dissolving liquid into inlet pipe 12, the other end of flange pipe 30 is connected to liquid pump. The dissolving liquid flows through flange pipe 30 and then into inlet pipe 12. At this time, the dissolving liquid has a certain pressure. Part of the dissolving liquid will enter the cylinder through liquid passage 2 311. Since the flow area of ​​liquid passage 2 311 is larger than that of liquid passage 4 3120, the amount of dissolving liquid flowing into the cylinder is more than the amount of dissolving liquid flowing through piston 2 312. This will increase the pressure on the left side of piston 2 312, thus pushing piston 2 312 against the elastic force of elastic member 2. This drives valve stem 325 to move through drive rod 315. As piston 2 312 moves, the valve stem 325 moves. When the end of the second liquid passage 311 is blocked by the side wall of the flange pipe 30, the flow area decreases. When it is less than the flow area of ​​the fourth liquid passage 3120, the amount of dissolved liquid entering the cylinder through the second liquid passage 311 is less than the amount entering through the fourth liquid passage 3120. Then, the second piston 312 returns to its original position under the elastic force of the second elastic element until the opening of the second liquid passage 311 is opened, and the flow area is again greater than the flow area of ​​the fourth liquid passage 3120. Then, the second piston 312 resists the elastic force of the second elastic element again. This process repeats, achieving the effect of driving the valve stem 325 to reciprocate. The greater the pressure of the liquid pumped in the flange pipe 30, the faster the flow medium enters the cylinder through the second liquid passage 311, and the faster the frequency of the reciprocating motion of the second piston 312.

[0069] Furthermore, as a specific implementation, the second elastic element is a compression spring 313 disposed on the side of the second piston 312 away from the piston rod 310. This method has a simple structure and a reasonable layout.

[0070] Furthermore, as a specific implementation method, refer to Figure 15 The other end of the liquid passage 314 is connected to the flange pipe 30, which is located at the end of the liquid inlet pipe 12. The flange pipe 30 has a constriction section located between the liquid passage 314 and the piston rod 310. By providing the constriction section inside the flange pipe 30, a pressure difference can be generated between the inside of the flange pipe 30 and its end, thereby facilitating the flow of liquid from the cylinder through the liquid passage 314 to the end of the flange pipe 30, making the reversing effect of the drive component 31 more sensitive.

[0071] Furthermore, as a specific implementation method, refer to Figure 13 To ensure that the drive component 31 can effectively drive the valve stem 325, the valve body 32 and the drive component 31 are designed in a certain proportion to ensure that the stroke of the piston 312 during reciprocating motion meets the stroke requirements of the valve stem 325 of the directional valve 3. Generally, the stroke that the piston 312 can move is designed to be greater than the stroke required by the valve stem 325. (Refer to...) Figure 15 , Figure 16In this application, a rigid cylinder is provided on the piston 312, and the drive rod 315 is guided and engaged with the rigid cylinder. A rigid plate is provided at the end of the drive rod 315 that extends into the rigid cylinder. Compression springs 316 are provided on both sides of the rigid rod, and limiting members 326 are provided at both ends of the valve cavity 324. The two compression springs 316 have the same parameters. When the valve rod 325 abuts against the limiting member 326 and the piston 312 continues to move before reaching its stroke, one compression spring 316 can be compressed to compensate for displacement. The two compression springs 316 can compensate for displacement in both directions, ensuring that the drive member 31 can effectively switch the operation of the reversing valve 3.

[0072] Furthermore, as a specific implementation, the reciprocating drive 4 is disposed at the top of the bacterial liquid chamber 2, and the reciprocating rod 40 is connected to the telescopic rod of the reciprocating drive 4 and the piston 212.

[0073] Specifically, the reciprocating rod 40 is rigidly set, and its lower end can be threaded to the piston 212. The reciprocating rod 40 passes through the bacterial liquid chamber 2. The structure such as disturbance blades can be set on the outside of the reciprocating rod 40 to disturb the solution in the bacterial liquid chamber 2, which can further improve the mixing uniformity.

[0074] Furthermore, as a preferred embodiment, refer to Figure 4 - Figure 6 Located below the mixing chamber 22, the stirring chamber 1 is also equipped with a flow equalization component 14, which includes:

[0075] Liquid tank 140 is located directly below mixing chamber 22;

[0076] Multiple liquid tanks 142 are arranged around liquid tank 140 at intervals and interconnected, and are connected to liquid tank 140 through liquid pipe 143. Multiple microholes 1410 are provided at the bottom.

[0077] Specifically, a support plate 141 is provided on the top of the stirring chamber 1. Liquid tank 140 and liquid tank 2 142 are both provided on the support plate. Liquid tank 140 has an opening at the top to receive the preliminary mixed solution flowing out of the mixing chamber 22. Multiple liquid tanks 2 142 are arranged at intervals around liquid tank 140. Adjacent liquid tanks 2 142 are connected by a connecting pipe 144 to ensure that the solution level in each liquid tank 2 142 is consistent. Each liquid tank 2 142 is connected to liquid tank 140 through a liquid pipe 143. One end of the liquid pipe 143 is connected to the bottom of liquid tank 140, and the other end is connected to the top of liquid tank 2 142, so that the solution in liquid tank 140 can be evenly distributed into each liquid tank 2 142. Multiple microholes 1410 are evenly distributed along the bottom of each liquid tank 2 142. The diameter of the microholes 1410 can be set according to the actual mixing requirements (e.g., 0.5-2mm). The technical advantages of this claim are as follows: the uniform flow component 14 allows the initially mixed solution to first enter the liquid tank 140 for buffering, and then be evenly distributed to each liquid tank 142 through the liquid pipe 143. The solution flows out from the micropores 1410 at the bottom of the liquid tank 142, forming fine droplets or liquid streams, which increases the contact area between the solution and other solutions in the stirring chamber 1, making it easier to achieve more thorough mixing in the subsequent stirring process. The surrounding arrangement of multiple liquid tanks 142 allows the solution to be evenly dispersed to various areas of the stirring chamber 1, further reducing agglomeration and improving the mixing uniformity.

[0078] Example 3

[0079] Further, refer to Figure 18 This application provides a process for preparing lactic acid bacteria by dissolving them to regulate intestinal flora, using any of the dissolving devices described above, and including the following steps:

[0080] Step 1: Mix the lactic acid bacteria powder according to the predetermined ratio to form a bacterial solution, and add the bacterial solution to the bacterial solution chamber 2; mix the lactic acid bacteria powder with an appropriate amount of solvent (such as sterile water, physiological saline or part of the beverage base liquid) and stir to prepare a uniform bacterial solution, avoiding clumping caused by direct addition of bacterial powder, and then add the prepared bacterial solution into the bacterial solution chamber 2 through the feed port of the bacterial solution chamber 2, and seal the feed port after the addition is completed.

[0081] Step 2: Pump a solution of predetermined pressure into the inlet pipe 12. The solution flows into the mixing chamber 22 through the inlet pipe 12.

[0082] Step 3: The reciprocating rod 40 drives the piston 212 to reciprocate according to the pumping pressure of the solution, transporting the bacterial solution in the bacterial solution chamber 2 to the mixing chamber 22, and driving the disturbance rod 213 to agitate the solution in the mixing chamber 22 to achieve preliminary mixing; The reciprocating rod 40 automatically adjusts the driving frequency according to the pumping pressure of the solution in the inlet pipe 12, driving the piston 212 to reciprocate along the piston cylinder 211 axially, and the bacterial solution in the piston cylinder 211 is transported to the mixing chamber 22 through the internal channel 2130. At the same time, the disturbance rod 213 moves downward with the piston 212 to agitate the solution and bacterial solution in the mixing chamber 22 to achieve preliminary mixing of the two.

[0083] Step 4: The solution in mixing chamber 22 flows to stirring chamber 1, where it is stirred and mixed again. The solution initially mixed in mixing chamber 22 flows into stirring chamber 1 under the influence of gravity and the subsequent solution. The stirring structure (such as a stirring paddle) in stirring chamber 1 further stirs and mixes the solution. Simultaneously, the solution flows through the flow equalization component 14, further improving the mixing uniformity, ultimately resulting in a uniform intestinal flora conditioning beverage. The technical advantages of this claim are: the process steps are simple and reasonable, perfectly compatible with the aforementioned equipment; by pre-preparing the bacterial solution, the clumping problem of directly adding bacterial powder is avoided; the bacterial solution delivery volume and dissolving pressure are strongly linked, ensuring accurate mixing ratios; the combination of initial mixing and re-stirring, along with the flow equalization component 14, significantly improves mixing uniformity and efficiency, resulting in a uniform distribution of lactic acid bacteria in the produced beverage, ensuring product quality stability.

However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
