Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of fermentation, in particular to a fermentation device for active probiotics. BACKGROUND

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

[0003] In the existing strain feeding process, open feeding is prone to contamination with foreign bacteria, and feeding through a pipeline requires an external pipeline, and the pipeline sterilization process is complicated. Each feeding requires disassembly of the pipeline for sterilization, resulting in poor efficiency. Moreover, the existing technology can only sterilize the feeding pipeline, but cannot treat the bacterial liquid. SUMMARY

[0004] The present application aims to provide a fermentation device for active probiotics, which has a fully closed feeding process, reduces the contamination of foreign bacteria, and realizes internal and external sterilization treatment through the rotation of the distribution pipeline, without the need for pipeline disassembly and washing. This ensures that the pipeline for each feeding is in a sterile state, and the temperature outside the pipeline is controlled, allowing the bacterial liquid to be fed at an appropriate temperature. This not only ensures the survival rate of live bacteria but also greatly reduces the risk of contamination.

[0005] To achieve the above-mentioned purpose, the present application provides the following technical solution: a fermentation device for active probiotics, comprising:

[0006] A fermentation tank body, the top end of the fermentation tank body is used to close the cover plate, and a feeding structure is assembled on the cover plate;

[0007] The feeding structure includes a connecting pipeline, a seed liquid feeding pipeline is connected to the upper end of the middle part of the connecting pipeline, a rotatable distribution pipeline is sleeved inside the connecting pipeline, a three-way hole is formed in the distribution pipeline, an extraction pipeline and a feeding pipeline are connected to the two sides of the connecting pipeline, and the extraction pipeline and the feeding pipeline are intermittently connected to the three-way hole, a separation channel is arranged between the connecting pipeline and the distribution pipeline, one end of the distribution pipeline is connected to a sterilization ring, a ventilation hole is formed in one end of the sterilization ring and is intermittently connected to the distribution pipeline, and an outer hole is formed in the sterilization ring and is intermittently connected to the separation channel;

[0008] When the three-way hole is connected to the seed liquid feed pipe, the extraction pipe and the delivery pipe and is in a three-way state, the vent hole is connected to the inside of the distribution pipe. When the distribution pipe is rotated until the three-way hole is in a two-way state, the outer hole is connected to the separation channel and the vent hole is closed.

[0009] Furthermore, a blocking ring is connected to the inner wall in the middle of the connecting pipe and is in contact with the outer wall of the distribution pipe, and the blocking ring is respectively provided with slots communicating with the seed liquid feed pipe, the extraction pipe and the delivery pipe.

[0010] Furthermore, the disinfection ring also includes a ventilation pipe, which is installed inside the connecting pipe. One end of the connecting pipe is connected to a rotating part, and the driving rod of the rotating part is connected to one end of the distribution pipe.

[0011] Furthermore, a sealing ring is sleeved on the outer wall of one end of the distribution pipe, and a notch is provided on the sealing ring for intermittently docking with the external through hole.

[0012] Furthermore, one end of the ventilation pipe is connected to high-temperature disinfection steam through a pipe.

[0013] Furthermore, the material distribution pipeline, the material extraction pipeline and the material delivery pipeline are all provided with pipelines for discharging wastewater.

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

[0015] Furthermore, a piston plate is provided in the pumping pipe, and one end of the piston plate is connected to the output end of the cylinder.

[0016] Furthermore, an agitator is installed inside the end of the extraction pipe away from the cylinder, and the agitator is connected to the piston plate through a telescopic pipe.

[0017] Furthermore, a driving inner rod passing through the piston plate is provided at the inner end of the telescopic pipe, one end of the driving inner rod is connected to the agitator, and an inner groove for the driving inner rod to penetrate is provided in the output rod of the cylinder, a spiral groove is provided on the inner wall of the inner groove, and an insert block is vertically installed on the driving inner rod, and the insert block is inserted in the spiral groove.

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

[0019] 1. The present invention reduces the mixing of miscellaneous bacteria by setting a fully enclosed process of the feeding structure, divides the feeding and feeding into two channels, realizes double-enclosure of feeding and feeding, avoids the connection of the feeding channel and the feeding channel during the feeding process, effectively isolates the entry of miscellaneous bacteria, and realizes internal and external sterilization through the rotation of the distribution pipe. The feeding pipe, the extraction pipe and the feeding pipe can be sterilized before each feeding, without the need to disassemble and clean the pipes, ensuring that the pipes for each feeding are in a sterile state, and by rotating the distribution pipe, the sterilization state can be automatically adjusted while switching the feeding channel, realizing sterilization in the tank before feeding.

[0020] 2. The extended pipe of the present invention extends the over-temperature channel of the connecting pipe. When over-temperature disinfection is carried out, the seed liquid is in an over-temperature state when it enters the distribution pipe. When it is extracted into the extraction pipe, the first over-temperature time is extended through the extended pipe. When the seed liquid passes through the extraction pipe and into the feeding pipe, it is over-heated for the second time.

[0021] 3. By setting up a stirrer, during the process of pumping the seed liquid, the stirrer can be driven to rotate automatically to stir the seed liquid in the pipeline, so that the seed liquid can be evenly overheated without affecting the activity of the bacteria itself, thereby improving the quality of subsequent fermentation. The stirrer is driven to rotate by the groove locking limit method to avoid adding additional power, and the drive is achieved by moving the output rod to ensure that the stirrer can rotate to stir the seed liquid during the process of pumping the seed liquid.

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] In order to better understand the fermentation device of an active probiotic provided in this embodiment, the following first briefly introduces the existing fermentation device of active probiotics. The seed tank and the fermentation tank in the prior art are connected by a pipeline. The positive pressure of the seed tank is greater than 0.05MPa, and the negative pressure of the fermentation tank is used to press the seed liquid into the fermentation tank. When the sterilization of the pipeline connection is not thorough, the residual spores enter the fermentation tank through the pressure difference. The pressure control method is difficult in a tank body greater than 5000L, which can easily cause liquid overflow or uneven mixing. The specification is intended to solve the above technical problems. The embodiment of the present application provides a fermentation device of active probiotics, which is fully enclosed by setting a feeding structure 2 process , reduce the mixing of miscellaneous bacteria, divide the feeding and feeding into two channels, realize double closure of feeding and feeding, avoid the feeding channel and feeding channel being connected during the feeding process, effectively isolate the entry of miscellaneous bacteria, and realize internal and external sterilization through the rotation of the distribution pipe 23. The feeding pipe, the extraction pipe and the feeding pipe can be sterilized before each feeding to ensure that the pipe for each feeding can be in a sterile state, and the distribution pipe 23 can be rotated to automatically adjust the sterilization state while switching the feeding channel to realize sterilization in the tank before feeding. During feeding, the temperature outside the tube is controlled so that the bacterial solution can be fed at overtemperature, which greatly reduces the risk of contamination while ensuring the survival rate of live bacteria.

[0040] Example 1: Reference 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. The fermentation tank body 1 is equipped with a high-temperature steam disinfection system, which is used to perform high-temperature overall sterilization on the tank body before fermentation, effectively avoiding the growth of bacteria in the tank and affecting the later fermentation. The high-temperature steam disinfection system equipped in the fermentation tank body 1 can be connected to the feeding structure 2, and the high-temperature steam is used to disinfect the feeding structure 2.

[0041] The top of the fermentation tank body 1 is equipped with a feed structure 2 on the cover 11 for sealing. The feed structure 2 includes a connecting pipe 21. The upper end of the middle of the connecting pipe 21 is connected to a seed liquid feed pipe 22. A rotatable distribution pipe 23 is sleeved inside the connecting pipe 21. A three-way hole 231 is opened in the distribution pipe 23. The two sides of the connecting pipe 21 are respectively connected to a pumping pipe 24 and a feeding pipe 25 that are intermittently connected to the three-way hole 231. A separation channel 211 is provided between the connecting pipe 21 and the distribution pipe 23. One end of the distribution pipe 23 is connected to a disinfection ring 26. One end of the disinfection ring 26 is opened with a connection to the distribution pipe. The vent hole 261 of the channel 23 is intermittently connected, and the disinfection ring 26 is provided with an external through hole 262 which is intermittently connected to the separation channel 211. When the distribution pipe 23 rotates, the three-way hole 231 can be rotated into three states. The first state is the three-way state, so that the seed liquid feeding pipe 22, the extraction pipe 24 and the feeding pipe 25 are all interconnected. When adjusted to the three-way state, the disinfection ring 26 automatically performs high-temperature steam sterilization on the distribution pipe 23, and the high-temperature steam can simultaneously sterilize the seed liquid feeding pipe 22, the extraction pipe 24 and the feeding pipe 25 in the three-way state; the pipeline cleaning and sterilization before each feeding is realized;

[0042] The second state is the two-way pumping state. In the two-way pumping state, the seed liquid feed pipe 22 and the pumping pipe 24 are interconnected, and the feed pipe 25 is closed alone. At this time, the pumping pipe 24 serves as a liquid inlet measuring pipe to achieve quantitative liquid pumping;

[0043] The third state is the two-way liquid inlet state. In the two-way liquid inlet state, the extraction pipe 24 and the feeding pipe 25 are interconnected, and the seed liquid feeding pipe 22 is closed separately. In the second state and the third state, the disinfection ring 26 feeds the seed liquid through the distribution pipe 23 at a superheated temperature, realizing internal disinfection before feeding and external disinfection during feeding. Through internal and external coordination, while ensuring closed feeding, the sterilization treatment efficiency is greatly improved.

[0044] When the three-way hole 231 is connected to the seed liquid feed pipe 22, the extraction pipe 24 and the delivery pipe 25 and is in a three-way state, the vent hole 261 is connected to the inside of the distribution pipe 23. When the distribution pipe 23 is rotated to the three-way hole 231 and is in a two-way state, the outer hole 262 is connected to the separation channel 211, and the vent hole 261 is closed. While feeding is achieved through the distribution pipe 23 and the disinfection ring 26, the quality of the bacterial liquid can be guaranteed, thereby improving the preparation effect of probiotics.

[0045] A sealing inner ring is connected to the inner wall in the middle of the connecting pipe 21, which is in contact with the outer wall of the distribution pipe 23, and the sealing inner ring is respectively provided with slots communicating with the seed liquid feed pipe 22, the extraction pipe 24 and the 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, and the sealing inner ring and the connecting pipe 21 are connected by three docking blocks, and the docking blocks are also provided with slots communicating with the seed liquid feed pipe 22, the extraction pipe 24 and the feeding pipe 25. The cavities between the two ends of the inside of the connecting pipe 21 and the distribution pipe 23 are in a state of communication, which is convenient for high-temperature steam to enter and overheat the connecting pipe 21 in a wrapped manner.

[0046] Extension pipes 213 are provided at both ends of the connecting pipe 21. The two extension pipes 213 are respectively covered on one end of the extraction pipe 24 and the feeding pipe 25, and the extension pipes 213 are interconnected with the connecting pipe 21. The extension pipes 213 extend the overtemperature channel of the connecting pipe 21. When overtemperature disinfection is carried out, the seed liquid is in an overtemperature state when it enters the inside of the distribution pipe 23. When it is extracted into the extraction pipe 24 and passes through the extension pipe 213, the first overtemperature time is extended. When the seed liquid passes from the extraction pipe 24 through the distribution pipe 23 and enters the feeding pipe 25, it is overheated for the second time. The extension pipe 213 greatly extends the overtemperature time, improves the effect of overtemperature sterilization, and once again ensures the sterility of the seed liquid feeding, thereby improving the quality of later preparation.

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

[0048] A sealing ring 232 is sleeved on the outer wall of one end of the distribution pipe 23, and a notch is provided on the sealing ring 232 that 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 that 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 sealing ring 232 rotates with the distribution pipe 23. When the three-way hole 231 and the seed liquid feeding pipe 22, the extraction pipe 24 and the feeding pipe 25 are in an interconnected state, the sealing ring 232 and the outer through hole 262 are staggered, and the outer through hole 262 is closed by the sealing ring 232. When the three-way hole 231 rotates to the two-way state, the air vent 261 and the steam inlet 233 are in a conducting state, and the disinfection steam connected to the ventilation pipe 263 enters the distribution pipe 23, and then the high-temperature gas is dispersed to the seed liquid feed pipe 22, the extraction pipe 24 and the feeding pipe 25 to realize high-temperature sterilization of the inside of the pipe. When the three-way hole 231 rotates to the two-way state, the air vent 261 and the steam inlet 233 are staggered to the blocked state. The blocking ring 232 is aligned with the outer hole 262 and is connected. 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 sterilization steam through a pipe. The high-temperature sterilization steam is not only used to sterilize the inside of the feed structure 2, but also 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 wastewater. When high-temperature disinfection is carried out in the pipe, steam is easily condensed in the pipe wall and finally gathers at the bottom of the pipe, and the gathered wastewater is discharged through the pipe. It should be noted that during the pipe disinfection process, the pipe is continuously discharging wastewater. When the disinfection is completed, if there are still water droplets attached to the inner wall of the pipe, it can be sucked or squeezed through the piston plate 241 in the extraction pipe 24, and repeated positive and negative pressures are used to make the collection easy 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 pipe 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 pipe 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 when the seed liquid was extracted and transported, the disinfection ring 26 conducted heat to the outer wall of the pipeline, and the seed liquid was overheated when it was pumped through the pipeline. However, during the pumping process, the temperature of the seed liquid in contact with the pipe wall in the pipeline was the highest, and the internal seed liquid could not be evenly overheated. If the temperature of the seed liquid in contact with the inner wall of the pipeline was too high for a long time, it would affect the activity of the bacteria.

[0054] In order to solve the above problems, this embodiment sets an agitator 242. During the process of pumping the seed liquid, the agitator 242 can be driven to rotate automatically to stir the seed liquid in the pipeline, so that the seed liquid can be evenly overheated without affecting the activity of the bacteria itself, thereby improving the quality of subsequent fermentation.

[0055] The end of the pumping pipe 24 away from the cylinder is provided with an agitator 242. The agitator 242 is connected to the piston plate 241 through a telescopic pipe 2421. The inner end of the telescopic pipe 2421 is provided with a driving inner rod 243 that penetrates the piston plate 241. One end of the driving inner rod 243 is connected to the agitator 242, and an inner groove for driving the 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. An insert block 2431 is vertically installed on the driving inner rod 243, and the insert block 2431 is inserted in the spiral groove 31. When the output rod 3 of the cylinder moves, the spiral groove 31 cooperates with the insert block 2431, and then drives the driving inner rod 243 to rotate, thereby driving the agitator 242 to rotate. The groove is engaged and limited to drive the agitator 242 to rotate, avoiding the addition of extra power, and the drive is achieved by moving the output rod 3 to ensure that the agitator 242 can rotate to stir the seed liquid during the seed liquid pumping process.

[0056] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
