Description

Technical Field

[0001] This utility model relates to the field of lactic acid bacteria processing technology, specifically to a pre-storage device for pre-storing and transferring lactic acid bacteria fermentation broth. Background Technology

[0002] In industries such as dairy products, probiotic preparations, functional foods, and biopharmaceuticals, lactic acid bacteria serve as core fermentation strains, and the quality of their fermentation broth directly affects the activity, stability, and safety of the final product. After fermentation, lactic acid bacteria fermentation broth requires temporary storage, transportation, and subsequent inoculation or bottling. Currently, the equipment for storing and transferring lactic acid bacteria fermentation broth generally involves transferring the fermentation broth to ordinary stainless steel drums via pipelines or pumps after fermentation, covering them for temporary storage or transportation, and then manually disassembling and cleaning, high-temperature steaming, or chemical sterilization after use. However, during the transfer process, the drums and lids are exposed to the air, which can easily introduce contaminants. Therefore, a new type of pre-storage device for pre-storing and transferring lactic acid bacteria fermentation broth is needed. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the above-mentioned technical defects and provide a novel pre-storage device for pre-storing and transferring lactic acid bacteria fermentation broth.

[0004] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a pre-storage device for pre-storing and transferring lactic acid bacteria fermentation broth, including a pre-storage tank, a material tank, and a cleaning and disinfection mechanism; The bottom of the pre-storage tank is equipped with multiple evenly placed support columns. The material tank is placed inside the pre-storage tank, with the top open and sealed by a cover plate. The bottom of the material tank extends to the outside of the pre-storage tank and is equipped with a discharge pipe. The pre-storage tank has a feeding pipe at the top inside. The feeding pipe is a telescopic pipe. Valves are installed in the feeding pipe and the unloading pipe. After the lifting mechanism moves the cover plate to be close to or away from the tank, the cleaning and disinfection mechanism disinfects the inside of the tank and the cover plate. Both the feeding pipe and the unloading pipe are connected to the disinfected disposable pipe through a connecting mechanism.

[0005] As an improvement, the lifting mechanism includes a pair of hydraulic telescopic rods, which are fixed between the cover plate and the inner wall of the top of the pre-storage tank.

[0006] As an improvement, a rubber plug is also provided on the bottom surface of the cover plate, which is in close contact with the inner wall of the material barrel. Under the push of the hydraulic telescopic rod, it forms a seal against the inner wall of the material barrel to prevent shaking and leakage.

[0007] As an improvement, the cleaning and disinfection mechanism includes a heating plate, a temperature sensor, and a temperature controller; The heating plate is installed on the inner wall around the pre-storage container, and the temperature sensor is installed at the top inside the pre-storage container and connected to the temperature controller on the outer wall of the pre-storage container. The temperature sensor and the temperature controller work together to achieve constant temperature sterilization.

[0008] As an improvement, a water level sensor is also included. The water level sensor is embedded in the bottom surface of the cover plate. After clean water is injected into the material bucket through the feed pipe, the water level sensor works with the cover plate to soak and clean it. After cleaning, the material bucket is disinfected by a cleaning and disinfection mechanism. The water level sensor works with automatic water injection to reduce manual intervention and improve operational consistency.

[0009] As improvements, the intake and exhaust pipes are also included; The air inlet pipe and the exhaust pipe are installed on the top wall of the pre-storage tank to maintain stable pressure inside the tank. The air inlet pipe and the exhaust pipe maintain stable pressure inside the tank and prevent leakage or equipment damage caused by pressure fluctuations due to heating or liquid flow.

[0010] As an improvement, the connection mechanism includes an external threaded sleeve and an internal threaded sleeve; Both the feed pipe and the discharge pipe extend to the outside of the pre-storage tank and are connected to external threaded sleeves. The end of the disposable feed pipe is equipped with an internal threaded sleeve that matches the external threaded sleeve.

[0011] The advantages of this utility model compared with the prior art are as follows: 1. The material hopper is completely enclosed in the pre-storage hopper and connected to a disposable material pipe through telescopic feeding and unloading pipes, avoiding contact with outside air during operation and greatly reducing the risk of contamination; 2. Equipped with a water level sensor and a cleaning and disinfection mechanism, it can automatically fill water and soak for cleaning, and heat the material to above 121℃ via a heating plate for dry heat or wet heat sterilization, ensuring that the inside of the material tank and cover plate reaches a sterile state; 3. The upper and lower feed ports are connected by a disposable feed tube using an external threaded sleeve and an internal threaded sleeve. This makes disassembly and assembly convenient, and a new tube is replaced after each use, completely avoiding residue and cross-contamination. Attached Figure Description

[0019] The present invention will now be described in further detail with reference to the accompanying drawings.

[0020] Example 1 Pre-storage device for pre-storing and transferring lactic acid bacteria fermentation broth, combined with attached Figure 1 and 3 As shown in Figure -4, the device includes a pre-storage tank 1, a material tank 2, and a cleaning and disinfection mechanism. The bottom of the pre-storage tank 1 has multiple evenly spaced support columns 3. The material tank 2 is located inside the pre-storage tank 1, with an open top and a cover plate 4. The bottom of the material tank 2 extends to the outside of the pre-storage tank 1 and is equipped with a discharge pipe 5. The top of the inside of the pre-storage tank 1 is equipped with a feed pipe 6, which is a telescopic pipe. Valves are installed inside both the feed pipe 6 and the discharge pipe 5. A lifting mechanism moves the cover plate 4 to be close to or away from the material tank 2. The lifting mechanism includes a pair of hydraulic telescopic rods 8, which are fixed between the cover plate 4 and the inner wall of the top of the pre-storage tank 1. A rubber plug 9 is also provided on the bottom surface of the cover plate 4, which is in close contact with the inner wall of the material tank 2. After the lifting mechanism moves the cover plate 4 away from the material bucket 2, the cleaning and disinfection mechanism disinfects the inside of the material bucket 2 and the cover plate 4. The cleaning and disinfection mechanism includes a heating plate 10, a temperature sensor 11, and a temperature controller 12. The heating plate 10 is set on the inner wall of the pre-storage bucket 1. The temperature sensor 11 is set at the top inside the pre-storage bucket 1 and is connected to the temperature controller 12 on the outer wall of the pre-storage bucket 1. It also includes a water level sensor 13, which is embedded in the bottom surface of the cover plate 4. After clean water is injected into the material bucket 2 through the feed pipe 6, the water level sensor 13 works with the cover plate 4 to soak and clean it. The cleaned material bucket 2 is then disinfected by the cleaning and disinfection mechanism. Water is injected through the feed pipe 6. After the water level sensor 13 detects that the liquid level has reached the set height, the water injection stops, immersing and rinsing the inside of the material tank 2 and the cover plate 4. After the wastewater is discharged through the discharge pipe 5, the valve of the discharge pipe 5 is closed. The hydraulic telescopic rod 8 pulls the cover plate 4 away from the material tank 2, and the heating plate 10 is activated. The temperature controller 12 sterilizes the inside of the pre-storage tank 1 and the surface of the material tank 2 at high temperature according to the set program (such as maintaining 121℃ for 30 minutes). After sterilization, it naturally cools to a safe temperature. The hydraulic telescopic rod 8 extends, pushing the cover plate 4 down. The rubber block 9 is tightly attached to the inner wall of the material tank 2 to form an airtight seal, and the fermentation liquid can then be injected into the sterilized material tank 2. It also includes an air inlet pipe 14 and an exhaust pipe 15; the air inlet pipe 14 and the exhaust pipe 15 are disposed on the top wall of the pre-storage tank 1 to maintain the pressure inside the pre-storage tank 1 stable.

[0021] Example 2 Based on Example 1, combined with Appendix Figure 2 and 5 As shown, both the feed pipe 6 and the discharge pipe 5 are connected to the sterilized disposable feed pipe 7 via a connecting mechanism, which includes an external threaded sleeve 16 and an internal threaded sleeve 17. The ends of both the feed pipe 6 and the discharge pipe 5 extend to the outside of the pre-storage tank 1 and are connected to the external threaded sleeve 16. The end of the disposable feed pipe 7 is provided with an internal threaded sleeve 17 that matches the external threaded sleeve 16. The disposable feed pipe 6 is connected to the feed pipe 6 via the external threaded sleeve 16, and the other end is connected to the outlet of the upstream fermentation tank. When the valve of the feed pipe 6 is opened, the fermentation liquid enters the feed tank 2 through the telescopic feed pipe 6. When transfer is required, the disposable discharge pipe 5 is connected to the discharge pipe 5, which leads to the downstream filling machine or reactor. The valve of the discharge pipe 5 is opened, and the fermentation liquid is transported to the next process by gravity or pumping, thereby achieving aseptic transfer.

[0022] In specific implementation of this utility model, clean water is injected through the feeding pipe 6. After the water level sensor 13 detects that the liquid level has reached the set height, the water injection stops, and the inside of the material tank 2 and the cover plate 4 are soaked and rinsed. After the sewage is discharged through the discharge pipe 5, the valve of the discharge pipe 5 is closed. The hydraulic telescopic rod 8 pulls the cover plate 4 away from the material tank 2, the heating plate 10 is activated, and the temperature controller 12 performs high-temperature sterilization on the inside of the pre-storage tank 1 and the surface of the material tank 2 according to the set program (such as maintaining 121℃ for 30 minutes). After sterilization, it is naturally cooled to a safe temperature. The hydraulic telescopic rod 8 extends, pushing the cover plate 4 down. The rubber block 9 is tightly attached to the inner wall of the material bucket 2 to form an airtight seal. The disposable feeding pipe 6 is connected to the feeding pipe 6 through the external threaded sleeve 16, and the other end is connected to the discharge port of the upstream fermentation tank. The valve of the feeding pipe 6 is opened, and the fermentation liquid enters the material bucket 2 through the telescopic feeding pipe 6. When transfer is required, connect the disposable feed pipe 5 to the feed pipe 5, which leads to the downstream filling machine or reactor. Open the valve of the feed pipe 5 and transport the fermentation liquid to the next process by gravity or pumping. The air inlet pipe 14 and the exhaust pipe 15 automatically adjust the pressure in the pre-storage tank 1 to prevent pressure buildup or backflow. After the transfer is completed, close all valves, disassemble the disposable material tube 7 and material tank 2, and dispose of them as medical waste. Perform the above-mentioned cleaning and disinfection process on material tank 2 in preparation for the next cycle of use.
