Description

Technical Field

[0001] The present invention relates to the field of fermentation technology, and particularly to a fermentation device for active probiotics. Background Art

[0002] Probiotics generally refer to live bacteria beneficial to the human body, such as lactic acid bacteria, bifidobacteria, etc. The fermentation process generally includes steps such as strain selection, culture medium preparation, sterilization, inoculation, fermentation control, harvesting, etc. The addition of strains (seed liquid) and auxiliary materials (such as culture medium components, feeding substances) has different stages and methods. Strains are usually added through a specific inoculation port into the sterilized fermentation tank, while auxiliary materials may be added before or after sterilization, depending on whether they are heat-resistant. For example, some culture medium components need to be sterilized together with the tank body, while some heat-sensitive auxiliary materials need to be added aseptically after sterilization. In the industrial fermentation of active probiotics, the feeding of strains (seed liquid) and auxiliary materials (such as carbon sources, nitrogen sources, trace elements) is a key link affecting fermentation efficiency and product quality.

[0003] In the existing process of discharging strains, in the case of open feeding, it is easy to mix in miscellaneous bacteria. While for feeding through pipelines, external pipelines need to be connected, and the pipeline disinfection process is complicated. Each time of feeding requires the pipeline to be disassembled for sterilization once, resulting in poor efficiency. Moreover, the existing technology can only disinfect the feeding pipeline and cannot treat the bacterial liquid being fed. Summary of the Invention

[0004] The purpose of the present invention is to provide a fermentation device for active probiotics, which has a fully enclosed process, reduces the mixing of miscellaneous bacteria, realizes internal and external sterilization treatment through the rotation of the distribution pipeline, eliminates the need for pipeline disassembly and cleaning, ensures that the pipeline for each feeding can be in a sterile state, controls the temperature outside the pipeline, enables the bacterial liquid to be fed at a proper temperature, and while ensuring the survival rate of live bacteria, greatly reduces the pollution risk.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A fermentation device for active probiotics, comprising:

[0006] A fermentation tank body, on the cover plate for closing at the top of the fermentation tank body, a feeding structure is assembled;

[0007] The feeding structure includes a connecting pipeline. At the upper middle part of the connecting pipeline, a seed liquid feeding pipeline is connected. Inside the connecting pipeline, a rotatable distribution pipeline is sleeved. Three through-holes are opened in the distribution pipeline. On both sides of the connecting pipeline, a pumping pipeline and a feeding pipeline that are intermittently communicated with the three through-holes are respectively connected. A separation channel is arranged between the connecting pipeline and the distribution pipeline. One end of the distribution pipeline is connected to a disinfection ring part. One end of the disinfection ring part is provided with a ventilation hole that is intermittently communicated with the distribution pipeline. An external through-hole that is intermittently communicated with the separation channel is opened on the disinfection ring part;

[0008] When the three through-holes are all connected to the seed liquid feeding pipeline, the material pumping pipeline and the material feeding pipeline and are in a three-way state, the ventilation hole is internally connected to the material distribution pipeline. When the material distribution pipeline rotates to a two-way state of the three through-holes, the outer through-hole is connected to the separation channel, and the ventilation hole is closed.

[0009] Furthermore, a sealing ring that fits the outer wall of the material distribution pipeline is connected to the inner wall at the middle of the connecting pipeline, and communication notches are respectively formed in the sealing ring for the seed liquid feeding pipeline, the material pumping pipeline and the material feeding pipeline.

[0010] Furthermore, the disinfection ring member further includes a ventilation pipeline installed inside the connecting pipeline. One end of the connecting pipeline is connected to a rotating member, and the driving rod of the rotating member is connected to one end of the material distribution pipeline.

[0011] Furthermore, a sealing ring is sleeved on the outer wall of one end of the material pipeline, and a notch that is intermittently docked with the outer through-hole is formed in the sealing ring.

[0012] Furthermore, high-temperature disinfection steam is introduced into one end of the ventilation pipeline through a pipeline.

[0013] Furthermore, pipelines for discharging waste water are provided on the material distribution pipeline, the material pumping pipeline and the material feeding pipeline.

[0014] Furthermore, one end of the material pumping pipeline is connected to a cylinder, and the material pumping pipeline serves as a container for quantitative feeding.

[0015] Furthermore, a piston plate is arranged inside the material pumping pipeline, and one end of the piston plate is connected to the output end of the cylinder.

[0016] Furthermore, a stirrer is installed inside the end of the material pumping pipeline far from the cylinder, and the stirrer is connected to the piston plate through a telescopic pipeline.

[0017] Furthermore, a driving inner rod penetrating through the piston plate is arranged at the inner end of the telescopic pipeline. One end of the driving inner rod is connected to the stirrer, and an inner groove for the driving inner rod to penetrate is formed in the output rod of the cylinder. A spiral groove is formed on the inner wall of the inner groove, and an insertion block is vertically installed on the driving inner rod, and the insertion block is inserted into the spiral groove.

[0018] The technical effects and advantages of the present invention:

[0019] 1. The present invention reduces the mixing of miscellaneous bacteria by setting a fully enclosed process for the feeding structure. The feeding and feeding are divided into two channels to achieve double-closed feeding and feeding, avoiding the connection of the feeding channel and the feeding channel during the feeding process, effectively isolating the entry of miscellaneous bacteria. Through the rotation of the distribution pipe, internal and external sterilization treatment is achieved. Before each feeding, the feeding pipe, the pumping pipe, and the feeding pipe can be sterilized without pipeline disassembly and cleaning, ensuring that the pipeline for each feeding is in a sterile state. Moreover, through the rotation of the distribution pipe, while switching the feeding channel, the sterilization state can be automatically adjusted to achieve in-tank sterilization before feeding. During feeding, the temperature is controlled outside the pipe, enabling the bacterial liquid to be fed at an over-temperature, greatly reducing the pollution risk while ensuring the survival rate of live bacteria.

[0020] 2. The present invention extends the over-temperature channel of the connecting pipe. When performing over-temperature disinfection, the seed liquid is in an over-temperature state when it enters the internal part of the distribution pipe. When it is pumped into the pumping pipe, the first over-temperature time is extended through the extended pipe. When the seed liquid passes through the distribution pipe from the pumping pipe and enters the feeding pipe, secondary over-temperature occurs. The extended pipe greatly extends the over-temperature time, improves the effect of over-temperature sterilization, ensures the aseptic degree of the seed liquid feeding again, and improves the quality of later preparation.

[0021] 3. By setting a stirrer, during the pumping process of the seed liquid, the stirrer can be driven to rotate automatically to stir the seed liquid in the pipe, enabling the seed liquid to be evenly over-temperature without affecting the activity of its own bacteria species, improving the quality of subsequent fermentation. The stirrer is driven to rotate by the method of groove clamping and limiting, avoiding the addition of extra power, and the drive is achieved through the movement of the output rod, ensuring that the stirrer can rotate to stir the seed liquid during the pumping process of the seed liquid.

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0039] To better understand a fermentation device for active probiotics provided in this embodiment, a brief introduction to the existing fermentation device for active probiotics will be given first. In the prior art, the seed tank and the fermentation tank are connected by pipelines. Using the pressure difference (positive pressure in the seed tank > 0.05 MPa and negative pressure in the fermentation tank), the seed liquid is pressed into the fermentation tank. When the sterilization at the pipeline connection is not thorough, the residual spores enter the fermentation tank through the pressure difference. In a tank with a volume > 5000 L, it is difficult to control the pressure by the pressure difference method, which is likely to cause flooding or uneven mixing. The specification aims to solve the above technical problems. The embodiment of this application provides a fermentation device for active probiotics. By setting a fully enclosed process for the feeding structure 2, the mixing of miscellaneous bacteria is reduced. The feeding and feeding are divided into two channels to achieve double-closed feeding and feeding, avoiding the connection of the feeding channel and the feeding channel during the feeding process, effectively isolating the entry of miscellaneous bacteria. Through the rotation of the distribution pipeline 23, internal and external sterilization treatment is realized. Before each feeding, the feeding pipe, the pumping pipe, and the feeding pipe can be sterilized to ensure that the pipeline for each feeding is in a sterile state. And through the rotation of the distribution pipeline 23, while switching the feeding channel, the sterilization state can be automatically adjusted to achieve in-tank sterilization before feeding. During feeding, the temperature is controlled outside the pipe, enabling the bacterial liquid to be fed at a proper temperature. While ensuring the survival rate of live bacteria, the pollution risk is greatly reduced.

[0040] Example 1: Refer to Figure 1 - Figure 7 , which is the first embodiment of the present invention, provides a fermentation device for active probiotics, including a fermentation tank body 1. A high-temperature steam disinfection system is equipped inside the fermentation tank body 1, which is used for overall high-temperature sterilization of the tank body before fermentation, effectively avoiding the growth of bacteria in the tank and affecting the subsequent fermentation. And the high-temperature steam disinfection system equipped inside the fermentation tank body 1 can be docked with the feeding structure 2, and the high-temperature steam is used for disinfection of the feeding structure 2.

[0041] On the cover plate 11 for closing the top of the fermentation tank body 1, a feeding structure 2 is assembled. The feeding structure 2 includes a connecting pipe 21. At the upper middle part of the connecting pipe 21, a seed liquid feeding pipe 22 is connected. Inside the connecting pipe 21, a rotatable material distributing pipe 23 is sleeved. A three-way hole 231 is opened in the material distributing pipe 23. On both sides of the connecting pipe 21, a material pumping pipe 24 and a material feeding pipe 25 which are intermittently communicated with the three-way hole 231 are respectively connected. A separation channel 211 is arranged between the connecting pipe 21 and the material distributing pipe 23. One end of the material distributing pipe 23 is connected to a disinfection ring member 26. One end of the disinfection ring member 26 is provided with a ventilation hole 261 which is intermittently communicated with the material distributing pipe 23. An outer through hole 262 which is intermittently communicated with the separation channel 211 is opened on the disinfection ring member 26. When the material distributing pipe 23 rotates, the three-way hole 231 can rotate into three states. The first state is the three-way state, which makes the seed liquid feeding pipe 22, the material pumping pipe 24 and the material feeding pipe 25 all communicate with each other. When adjusted to the three-way state, the disinfection ring member 26 automatically performs high-temperature steam sterilization on the inside of the material distributing pipe 23, and the high-temperature steam can simultaneously sterilize the inside of the seed liquid feeding pipe 22, the material pumping pipe 24 and the material feeding pipe 25 in the three-way state; realizing the pipeline cleaning and sterilization before each feeding;

[0042] The second state is the two-way liquid pumping state. In the two-way liquid pumping state, the seed liquid feeding pipe 22 and the material pumping pipe 24 communicate with each other, and the material feeding pipe 25 is separately closed. At this time, the material pumping pipe 24 serves as a measuring pipe for the incoming liquid to realize quantitative liquid pumping;

[0043] The third state is the two-way liquid feeding state. In the two-way liquid feeding state, the material pumping pipe 24 and the material feeding pipe 25 communicate with each other, and the seed liquid feeding pipe 22 is separately closed. And in the second state and the third state, the disinfection ring member 26 performs over-temperature feeding on the seed liquid passing through the material distributing pipe 23, realizing internal disinfection before feeding and external disinfection during feeding. Through the internal and external cooperation, while ensuring closed feeding, the sterilization treatment efficiency is greatly improved.

[0044] When the three-way hole 231 is all communicated with the seed liquid feeding pipe 22, the material pumping pipe 24 and the material feeding pipe 25 and is in the three-way state, the ventilation hole 261 is communicated with the inside of the material distributing pipe 23. When the material distributing pipe 23 rotates to the three-way hole 231 in the two-way state, the outer through hole 262 is communicated with the separation channel 211, and the ventilation hole 261 is closed. Through the material distributing pipe 23 and the disinfection ring member 26, while realizing feeding, the quality of the bacterial liquid can also be guaranteed, and the preparation effect of probiotics is improved.

[0045] A sealing inner ring that fits against the outer wall of the material distribution pipe 23 is connected to the inner wall at the middle of the connecting pipe 21. Intercommunication notches are respectively formed in the sealing inner ring for the seed liquid feeding pipe 22, the material pumping pipe 24, and the material feeding pipe 25. The sealing inner ring is used to seal the three-way hole 231 when the three-way hole 231 is not connected to the pipe. The sealing inner ring and the connecting pipe 21 are connected by three docking blocks, and notches that communicate with the seed liquid feeding pipe 22, the material pumping pipe 24, and the material feeding pipe 25 are also formed in the docking blocks. The cavities between the two ends inside the connecting pipe 21 and the material distribution pipe 23 are in a communicating state, facilitating the entry of high-temperature steam to perform a wrapped over-temperature treatment on the connecting pipe 21.

[0046] Extension pipes 213 are provided at both ends of the connecting pipe 21. The two extension pipes 213 respectively wrap around one end of the material pumping pipe 24 and the material feeding pipe 25, and the extension pipes 213 communicate with the inside of the connecting pipe 21. The extension pipes 213 extend the over-temperature channel of the connecting pipe 21. When performing over-temperature disinfection, the seed liquid is in an over-temperature state when it enters the interior of the material distribution pipe 23. When it is pumped into the material pumping pipe 24, the first over-temperature time is extended by the extension pipes 213. When the seed liquid passes from the material pumping pipe 24 through the material distribution pipe 23 and into the material feeding pipe 25, a secondary over-temperature occurs. The extension pipes 213 greatly extend the over-temperature time, improve the over-temperature sterilization effect, ensure the aseptic degree of the seed liquid feeding again, and improve the quality of later preparation.

[0047] The disinfection ring member 26 further includes a ventilation pipe 263. The ventilation pipe 263 is installed inside the connecting pipe 21. One end of the connecting pipe 21 is connected to a rotating member. The driving rod 212 of the rotating member is connected to one end of the material distribution pipe 23. The driving rod 212 is driven by the rotating member. The rotating member can be a motor or a rotating cylinder. The driving rod 212 rotates under the drive of the rotating member, and then drives the material distribution pipe 23 to rotate, thereby adjusting the rotation state of the three-way hole 231. The rotation of the material distribution pipe 23 cooperates with the disinfection ring member 26 to achieve closed feeding adjustment while achieving internal and external disinfection.

[0048] A plugging ring 232 is sleeved on the outer wall of one end of the distribution pipe 23, and a groove is provided on the plugging ring 232 which intermittently connects with the outer through hole 262. A section of outer expansion ring is provided on the ventilation pipe 263, and the outer through hole 262 is provided on one end face of the outer expansion ring, and the outer through hole 262 is semi-annular. A steam inlet 233 which is intermittently interconnected with the ventilation hole 261 is provided on the contact end face of the distribution pipe 23 and the ventilation pipe 263. The plugging ring 232 rotates with the distribution pipe 23. When the three-way hole 231 is in an interconnected state with the seed liquid feeding pipe 22, the extraction pipe 24 and the delivery pipe 25, the plugging ring 232 is staggered with the outer through hole 262, and the outer through hole 262 is closed by the plugging ring 232. When the three-way hole 231 rotates to the two-way state, the air hole 261 and the steam inlet hole 233 are in a conducting state, and the disinfection steam connected to the air pipe 263 enters the distribution pipe 23, and then the high-temperature gas is dispersed to the seed liquid feeding pipe 22, the extraction pipe 24 and the feeding pipe 25 by the three-way hole 231 to achieve high-temperature sterilization of the inside of the pipe. When the three-way hole 231 rotates to the two-way state, the air hole 261 and the steam inlet hole 233 are staggered to the blocking state. The blocking ring 232 is aligned and connected with the outer hole 262, and the gas enters the cavity between the distribution pipe 23 and the connecting pipe 21, and heats the outside of the distribution pipe 23, the extraction pipe 24 and the feeding pipe 25, so that the seed liquid passing through is over-temperature sterilized, thereby improving the sterilization effect.

[0049] One end of the ventilation pipe 263 is connected to high-temperature sterilizing steam through a pipe. The high-temperature sterilizing steam is not only used to sterilize the inside of the feed structure 2, but also used to sterilize the inside of the fermentation tank body 1 at high temperature.

[0050] The distribution pipe 23, the extraction pipe 24 and the feeding pipe 25 are all provided with pipes for discharging waste water. When high-temperature disinfection is carried out in the pipe, the steam is easily condensed in the pipe wall and finally gathers at the bottom of the pipe, and the gathered waste water is discharged through the pipe. It should be noted that during the pipe disinfection process, the pipe is continuously discharging waste water. When the disinfection is completed, if there are still water droplets attached to the inner wall of the pipe, the piston plate 241 in the extraction pipe 24 can be used for suction or squeezing, and repeated positive and negative pressures can be used to make the collection easier to discharge, which effectively solves the problem of beads hanging on the inner wall of the pipe.

[0051] One end of the pumping pipe 24 is connected to the cylinder, and the pumping pipe 24 serves as a container for quantitative feeding. The suction volume of the pumping pipe 24 determines the quantitative amount of feeding at one time.

[0052] A piston plate 241 is provided in the extraction pipeline 24, and one end of the piston plate 241 is connected to the output end of the cylinder. The cylinder drives the piston plate 241 to move in the extraction pipeline 24, thereby realizing the extraction and transportation of the seed liquid and improving the convenience of material transportation.

[0053] Example 2: Reference Figure 8 - Figure 9, which is the second embodiment of the present invention. This embodiment is different from the first embodiment. During the implementation of the first embodiment, it was found that during the process of extracting and transporting the seed liquid, the disinfection ring 26 conducts heat on the outer wall of the pipeline, and the seed liquid undergoes over-temperature treatment when being pumped through the pipeline. However, during the pumping process, the temperature of the seed liquid in contact with the pipe wall inside the pipeline is the highest, and the internal seed liquid cannot be evenly over-temperature. Moreover, if the temperature of the seed liquid in contact with the inner wall of the pipeline is too high for a long time, it will affect the activity of the bacteria.

[0054] To solve the above problems, in this embodiment, a stirrer 242 is provided. During the process of pumping the seed liquid, it can drive the stirrer 242 to rotate automatically, stir the seed liquid inside the pipeline, enable the seed liquid to be evenly over-temperature, and at the same time, it will not affect the activity of its own bacteria, improving the subsequent fermentation quality.

[0055] A stirrer 242 is installed inside the end of the pumping pipeline 24 away from the cylinder. The stirrer 242 is connected to the piston plate 241 through a telescopic pipeline 2421. The inner end of the telescopic pipeline 2421 is provided with a driving inner rod 243 penetrating through the piston plate 241. One end of the driving inner rod 243 is connected to the stirrer 242, and an inner groove for the driving inner rod 243 to penetrate is provided in the output rod 3 of the cylinder. A spiral groove 31 is provided on the inner wall of the inner groove. A plug-in block 2431 is vertically installed on the driving inner rod 243, and the plug-in block 2431 is inserted into the spiral groove 31. When the output rod 3 of the cylinder moves, through the cooperation of the spiral groove 31 and the plug-in block 2431, the driving inner rod 243 is driven to rotate, thereby driving the stirrer 242 to rotate. By using the method of groove clamping and limiting, the stirrer 242 is driven to rotate, avoiding the addition of extra power, and being driven by the movement of the output rod 3 to ensure that the stirrer 242 can rotate to stir the seed liquid during the process of pumping the seed liquid.

[0056] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
