Description

Technical Field

[0001] This utility model relates to the technical field of lactobacillus production equipment, specifically to a centrifugal filtration device for mass production of lactobacillus. Background Technology

[0002] The fermentation process of Lactobacillus is carried out in a liquid culture medium. After fermentation, the resulting fermentation broth is a mixture containing bacterial cells (target product), residual culture medium, and water. Before further processing of Lactobacillus, centrifugation and filtration are required to separate the bacterial cells from the culture medium in the fermentation broth, and the bacterial cells are extracted and transported to the subsequent processing equipment.

[0003] The prior art, Chinese utility model patent number CN220413366U, discloses a centrifugal filter for probiotic production. This centrifugal filter for probiotic production is equipped with a first magnet block and a second magnet block. Through the mutual repulsion between the first magnet block and the second magnet block with the same magnetic pole, the transmission shaft drives the filter frame to rotate while the filter frame can also move horizontally. At the same time, with the arrangement of the crossbar and the ball, the filter frame can impact the rubber ball, thereby avoiding blockage inside the filter frame and facilitating the centrifugal filtration operation of the filter frame.

[0004] In the aforementioned existing technical solutions, the cap and outer shell need to be separated after each centrifugation filtration to remove the bacteria from the filter frame, which is cumbersome and reduces work efficiency. Furthermore, since the bacteria are in a "wet mud" state, they easily adhere to the inner wall of the filter frame, forming an adhesive layer. The vibration generated by impacting the frame with a ball is relatively weak and still difficult to dislodge them, resulting in product waste. Utility Model Content

[0013] Furthermore, the cleaning assembly also includes a water storage tank and a spray pump. The water storage tank is connected to the input end of the spray pump via a pipe, and the output end of the spray pump is connected to a spray pipe.

[0014] Furthermore, the connecting part is a rotary joint, the discharge port at the bottom of the filter cylinder is connected to the rotating end of the rotary joint, the stationary end of the rotary joint is connected to the discharge pipe, the discharge pipe passes through the outer cylinder and extends out, and a recycling port is provided on the discharge pipe and a recycling pipe is connected to the recycling port.

After the culture medium is discharged after solid-liquid separation, the ball valve on the gas supply pipe is opened, and air is blown into the outer wall of the filter cylinder through each jet head. Some gas will enter the cylinder from the filter hole on the filter cylinder, thereby changing the adhesive layer formed on the inner wall of the filter cylinder from a dense state to a loose state, making it easier for the adhesive layer to fall off and be collected.

[0021] (3) By designing cleaning components, after the separated bacteria are discharged, the spray pump is started and the inner wall of the filter cartridge is rinsed through the spray head, thereby cleaning and recycling the bacteria remaining in the filter cartridge. This not only reduces resource waste, but also reduces clogging problems by rinsing the filter cartridge. Attached Figure Description

[0032] like Figures 1 to 5 As shown, this utility model provides a centrifugal filtration device for mass production of lactobacillus, characterized in that it includes a centrifugal filtration component, an air blowing component, and a cleaning component;

[0034] The air blowing assembly and the cleaning assembly are respectively located on the side of the centrifugal filter assembly, and the air blowing assembly and the cleaning assembly are respectively mounted on the support frame 1;

[0035] The air jet in the blowing assembly extends into the outer cylinder 21, and the air jet is located between the outer wall of the filter cylinder 22 and the inner wall of the outer cylinder 21, for blowing air onto the outer wall of the filter cylinder 22; the spray in the cleaning assembly extends into the inner filter cylinder 22, for spraying and cleaning the inner wall of the filter cylinder 22.

[0036] Specifically, through Figure 1 The overall structural diagram shows that the top of the outer cylinder 21 is equipped with a top cover 211, on which a feed inlet 212 is provided. As shown in the figure, the top cover 211 and the outer cylinder 21 are separate units, connected by a flange. The bottom of the outer cylinder 21 is connected to a drain pipe 213. Figure 4 From a certain perspective, the drain pipe 213 is provided with an exhaust port and an exhaust pipe 214 is installed at the exhaust port.

[0037] The connection between the filter cartridge 22 and the discharge pipe 23 is a rotary joint 24. This rotary joint 24 is a commercially available component used as a transitional part for connecting dynamic and static inertial navigation systems. It has two connecting ends: a rotating end for connecting to a rotating pipe and a stationary end for connecting to a static pipe. Therefore, its specific structure will not be described in detail. In this application, the discharge port at the bottom of the filter cartridge 22 is connected to the rotating end of the rotary joint 24, and the stationary end of the rotary joint 24 is connected to the discharge pipe 23, completing the adaptive connection between the filter cartridge 22 and the discharge pipe 23.

[0038] Depend on Figure 2 as well as Figure 3 As can be seen from the enlarged view, the air blowing assembly also includes an air storage tank 32. The air inlet of the air storage tank 32 is connected to the air outlet of the air compressor, and the air outlet of the air storage tank 32 is connected to an air delivery pipe 31. The air delivery pipe 31 extends into the outer cylinder 21 and is vertically arranged. The air delivery pipe 31 is fixed to the inner wall of the outer cylinder 21 by clamps. Multiple sets of air jets 311 are arranged at intervals on the air delivery pipe 31. The air compressor is a commercially available device, and its input end is connected to an air source. The air source must be a sterile inert gas, such as sterile nitrogen, to meet the aseptic production and processing requirements of lactobacillus fermentation products.

[0039] pass Figure 5The internal structure of the filter cartridge 22 is shown in the diagram. The cleaning assembly also includes a water storage tank 42 and a spray pump 43. The water storage tank 42 is connected to the input end of the spray pump 43 via a pipe, and the output end of the spray pump 43 is connected to a spray pipe 41.

The water storage tank 42 is provided with a water inlet and a water outlet for filling the water storage tank 42 and for periodic cleaning and drainage. The water in the water storage tank 42 is sterile water that has been sterilized.

[0040] In addition, a control box 5 is fixedly installed on one side of the support frame 1. Ball valves are installed on the air supply pipe 31, discharge pipe 23, recovery pipe 231, liquid discharge pipe 213 and exhaust pipe 214 in the centrifugal filtration device. Each ball valve, air compressor, spray pump 43 and drive motor 25 are electrically connected to the control box 5. The start and stop control of these electronic components is realized through the control box 5, so that the entire centrifugal water filtration process can be automated.

[0041] The working principle and process of this utility model are as follows:

[0042] During centrifugal filtration: The lactobacillus fermentation material is fed into the filter cylinder 22 through the feed inlet 212. The drive motor 25 is started to control the rotation of the filter cylinder 22. The rotation generates centrifugal force, causing the fermentation material to be thrown against the inner wall of the filter cylinder 22. The liquid is filtered out through the filter cylinder 22 and enters the cavity between the filter cylinder 22 and the outer cylinder 21, completing the solid-liquid separation. The ball valve on the drain pipe 213 is opened to discharge the separated culture medium. After the culture medium is discharged, the drive motor 25 and the ball valve on the drain pipe 213 are closed, while the ball valve on the discharge pipe 23 is opened to discharge the bacteria in the filter cylinder 22.

[0043] During air collection: To collect and discharge the bacteria that have formed an adhesive layer on the filter cylinder 22, the control box 5 controls the start of the air compressor and the opening of the ball valves on the air supply pipe 31 and the exhaust pipe 214, while closing the ball valve on the discharge pipe 23. The control box 5 also controls the drive motor 25 to rotate smoothly, causing the air jet 311 to blow air onto the outer wall of the filter cylinder 22. The gas enters the cylinder through the filter holes, thus changing the dense adhesive layer on the inner wall of the filter cylinder 22 into a loose state, facilitating its fall and collection into the conical bottom of the filter cylinder 22. The blown gas is then discharged through the exhaust pipe 214. After collection, the activated electronic components are turned off, and the ball valve on the discharge pipe 23 is opened to discharge the bacteria.

[0044] During rinsing and recycling: the spray pump 43 is started by the control box 5, and the drive motor 25 is controlled to rotate smoothly. The spray head 411 rinses the inner wall of the filter cylinder 22, so that the residual bacteria are discharged through the recycling pipe 231 for recycling. The rinsing water between the outer cylinder 21 and the filter cylinder 22 is discharged from the drain pipe 213 at the bottom of the outer cylinder 21.

[0045] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made within the scope of this utility model should still fall within the scope of this patent.
