The support frame 6 is retractable. Before use, the components of the device must be connected according to their respective connections. All electrical components within the device are externally connected to a power source and control switch to ensure proper operation. The working tank 1 serves as the main container of the device, housing the probiotic sample and performing the separation and concentration operations. The working leg 2 is disposed at the bottom of the working tank 1 to provide support and ensure stable positioning of the working tank 1. The sealing assembly 3 is mounted on the working tank 1 to ensure the sealing of the working tank 1, preventing leakage during operation that could affect the probiotic separation and concentration effect, and protecting against external contamination. The working assembly 4 is also disposed on the working tank 1 and is a key component directly involved in the probiotic separation and concentration process. It is connected to an auxiliary component 5, which is arranged on one side of the working tank 1. By cooperating with the working component 4, specific operations on the probiotics are achieved. The auxiliary component 5 is located on one side of the working tank 1, and a placement rack 6 is provided at the bottom. The placement rack 6 is retractable. This design enables the auxiliary component 5 to adjust its position according to actual needs to better cooperate with the working component 4. When it is necessary to get closer to the working tank 1 for precise operation, the placement rack 6 can be retracted; when it is necessary to make room for other components or perform maintenance, the placement rack 6 can be extended. The pressurizing component 7 is arranged at the bottom of the working tank 1 to create a certain pressure environment in the working tank 1, which helps the separation and concentration process of the probiotics and promotes the separation of the probiotics from impurities or solvents through the pressure difference.

[0026] Specifically, if Figure 1-Figure 5As shown, the working component 4 described in this embodiment includes a working bracket 41, which is arranged on the sealing component 3, and the working bracket 41 is connected to the sealing component 3. A working motor 42 is provided on the working bracket 41, and the working motor 42 is connected to a transmission box 43 through a connecting belt. The transmission box 43 is connected to a working main shaft 44, and the transmission box 43 is connected to an auxiliary rotating shaft 45.

A working plate 46 is provided at the top of the working main shaft 44, and a through hole 47 is provided on the working plate 46. A bent rod 48 is provided at the top of the auxiliary rotating shaft 45. The auxiliary assembly 5 includes an auxiliary chamber 51, a placement rack 6 is provided at the bottom of the auxiliary chamber 51, a heating pipe 52 is provided in the auxiliary chamber 51, and the heating pipe 52 is arranged on the inner wall of the auxiliary chamber 51. A heat dissipation vent 53 is provided at the top of the auxiliary chamber 51, and a cooling fan 54 is provided in the heat dissipation vent 53. A connecting discharge pipe 55 is provided in the auxiliary chamber 51, and the connecting discharge pipe 55 is connected to the transition pipe 310. A spiral tube 56 is provided at the bottom of the connecting discharge pipe 55, and an auxiliary air pipe 57 is connected to the connecting discharge pipe 55. The top of the auxiliary air pipe 57 is externally connected to an air pump, and the top of the spiral tube 56 is provided with a discharge valve 58. An auxiliary sealing door 59 is provided on the side of the auxiliary chamber 51. The working bracket 41 is arranged on the sealing assembly 3 and is tightly connected to the sealing assembly 3. During installation, it is necessary to ensure that the installation position of the working bracket 41 is accurate to ensure the normal installation and operation of subsequent components. The working motor 42 is installed on the working bracket 41 and connected to the transmission box 43 via a connecting belt. During installation, ensure that the tension of the connecting belt is moderate—neither too loose, resulting in low transmission efficiency, nor too tight, affecting the service life of the connecting belt, motor, and transmission box 43. Transmission box 43 is connected to the working spindle 44 and auxiliary rotating shaft 45, respectively. Both the working spindle 44 and auxiliary rotating shaft 45 are located within the working tank 1. During installation, the coaxiality of the working spindle 44 and auxiliary rotating shaft 45 must be ensured to reduce vibration and noise during operation. A dedicated coaxiality detection tool can be used for testing and adjustment to ensure that the error is within the allowable range. A working plate 46 is provided at the top of the working spindle 44, and a through hole 47 is provided in the working plate 46. The provision of through hole 47 facilitates the circulation of solution or gas exchange during operation. Its aperture and position should be designed according to actual process requirements. For example, the aperture of through hole 47 can be selected based on the size of the probiotic particles and the flow rate of the solution to ensure that the probiotics can pass smoothly while impurities are effectively trapped. A curved rod 48 is located at the top of the auxiliary shaft 45. The shape and size of the curved rod 48 should be designed according to specific operating requirements. A retractable shelf 6 is located below the auxiliary chamber 51. When installing the auxiliary chamber 51, place it on the shelf 6 and adjust the height and position of the shelf 6 as needed. A heating pipe 52 is located on the inner wall of the auxiliary chamber 51 to provide heat to the auxiliary chamber 51. When installing the heating pipe 52, ensure that it fits tightly against the inner wall of the auxiliary chamber 51 to improve heating efficiency.The heating tube 52 can be secured to the inner wall of the auxiliary chamber 51 using materials such as thermally conductive silicone. At the same time, ensure the wiring of the heating tube 52 is secure to avoid safety hazards such as short circuits. A heat dissipation vent 53 is located at the top of the auxiliary chamber 51, and a cooling fan 54 is installed within the vent 53. The cooling fan 54 dissipates heat from the auxiliary chamber 51 to maintain a stable temperature within the auxiliary chamber 51. When installing the cooling fan 54, ensure that it is securely mounted and that the airflow direction is correct to effectively dissipate heat from the auxiliary chamber 51. For example, the installation angle of the cooling fan 54 can be adjusted to optimize heat dissipation. A connecting drain pipe 55 is located within the auxiliary chamber 51 and connects to the transition pipe 310. A spiral tube 56 is located at the bottom of the connecting drain pipe 55. The design of the spiral tube 56 helps increase the residence time of the solution within the pipe, improving heat exchange efficiency. During installation, ensure that the connection between the connecting drain pipe 55, the transition pipe 310, and the spiral tube 56 is properly sealed to avoid leakage. Sealing can be achieved using materials such as gaskets or sealant. An auxiliary air pipe 57 is connected to the connecting discharge pipe 55, and an air pump is externally connected to the top of the auxiliary air pipe 57. The function of the air pump is to fill the auxiliary warehouse 51 with gas to meet the gas demand during the working process. When installing the air pump, ensure that it is firmly connected to the auxiliary air pipe 57, and the inflation pressure and flow can be adjusted according to the actual process requirements. A discharge valve 58 is provided at the top of the spiral tube 56, and the discharge valve 58 is used to control the discharge of the solution in the spiral tube 56. When installing the discharge valve 58, ensure that it is flexible in operation and has good sealing performance. An auxiliary sealing door 59 is provided on the side of the auxiliary warehouse 51. The function of the auxiliary sealing door 59 is to facilitate the inspection and maintenance of the components in the auxiliary warehouse 51. When installing the auxiliary sealing door 59, ensure that it is well sealed with the auxiliary warehouse 51, and the opening and closing of the auxiliary sealing door 59 should be flexible and convenient. The auxiliary sealing door 59 can be installed in a hinged connection manner, and a suitable locking device can be provided to ensure the stability of the auxiliary sealing door 59 during the working process.

[0027] Specifically, such as Figure 1-Figure 5As shown, the sealing assembly 3 of this embodiment includes a sealing cover 31, which is mounted on the working tank 1. A sealing strip 32 is disposed between the sealing cover 31 and the working tank 1. A connecting base 33 is provided on the sealing cover 31, which is connected to the working support 41 via a connecting shaft 34. A telescopic cylinder 35 is connected to the upper portion of the connecting base 33, which is connected to the working support 41 via a connecting shaft 36. A mounting bracket 37 is provided at the bottom end of the telescopic cylinder 35, which is mounted on the side of the working tank 1. A connecting pipe 38 is provided on the sealing cover 31, which is equipped with a filter pump 39. The filter pump 39 is connected to the auxiliary assembly 5 via a transition pipe 310. A pressure relief port 311 is provided on the sealing cover 31. The sealing cover 31 is mounted on the working tank 1. During installation, ensure that the sealing cover 31 is fully aligned with the opening of the working tank 1. A sealing strip 32 is installed at the corresponding position between the edge of the working tank 1 opening and the sealing cover 31. The sealing strip 32 should be made of a material with good elasticity and corrosion resistance, such as silicone. Evenly stick the sealing strip 32 on the opening edge of the working tank 1, then slowly place the sealing cover 31 on the working tank 1, and gently press it to make it fit tightly with the sealing strip 32 to initially form a sealing effect. The sealing cover 31 is provided with a connecting seat 33, and the connecting seat 33 is connected to the working bracket 41 through a connecting shaft 34. During installation, first firmly fix the connecting seat 33 on the sealing cover 31, which can be connected by welding or bolting. Then insert the connecting shaft 34 into the corresponding holes of the connecting seat 33 and the working bracket 41, and ensure that the connecting shaft 34 can rotate flexibly to ensure the smoothness of the sealing cover 31 during the opening and closing process. A telescopic cylinder 35 is connected to the upper part of the connecting seat 33, and the telescopic cylinder 35 is connected to the working bracket 41 through a connecting shaft 36. First, install the bottom end of the telescopic cylinder 35 on the mounting bracket 37, which is located on the side of the working tank 1. Use bolts to firmly secure the mounting bracket 37 to the side of the working tank 1. Then, connect the bottom end of the telescopic cylinder 35 to the mounting bracket 37 via a pin, ensuring that the telescopic cylinder 35 can rotate around the pin. Then, connect the top end of the telescopic cylinder 35 to the working bracket 41 via the connecting shaft 36. Similarly, ensure that the connecting shaft 36 can rotate flexibly so that the telescopic cylinder 35 can normally extend and retract to open and close the sealing cover 31. When the sealing cover 31 needs to be opened, the telescopic cylinder 35 is activated, and the telescopic cylinder 35 retracts, driving the working bracket 41 upward via the connecting shaft 36. The working bracket 41 then drives the connecting seat 33 and the sealing cover 31 upward via the connecting shaft 34, thereby opening the sealing cover 31. During the opening process, pay attention to the movement of the sealing cover 31 to ensure that it rises smoothly and avoids collision with the working tank 1 or other components. When the sealing cover 31 needs to be closed, the telescopic oil cylinder 35 is started to extend, and the sealing cover 31 moves downward through the above reverse transmission process, fits tightly with the working tank 1, and is sealed by the sealing strip 32.After closing, the seal can be tested by filling working tank 1 with gas at a certain pressure and observing the pressure change. If there is no significant pressure drop, the seal is good. During operation, the filter pump 39 extracts the solution from working tank 1 through connecting pipe 38. After filtration, it is then transported through transition pipe 310 to auxiliary assembly 5 for further processing. The flow rate and pressure of filter pump 39 should be selected and adjusted according to actual process requirements. When the pressure in working tank 1 exceeds the set safety value, the pressure relief valve automatically opens to release the excess pressure, ensuring that the pressure in working tank 1 remains within a safe range.

[0028] Further, such as Figure 1-Figure 5 As shown, the pressurizing assembly 7 described in this embodiment includes a pressurizing tube 71, a pressurizing piston 72 is provided at the bottom end of the pressurizing tube 71, the pressurizing piston 72 is connected to a pressurizing shaft 73, and a pressurizing turntable 74 is provided at the top end of the pressurizing shaft 73. The bottom end of the pressurizing tube 71 is connected to the bottom of the working tank 1 to ensure that the connection is well sealed to prevent pressure leakage. The pressurizing tube 71 can be fixed to the working tank 1 by welding or flange connection. When welding, the quality of the weld must be ensured to avoid defects such as pores and slag inclusions; for flange connection, suitable sealing gaskets must be selected and the bolts must be tightened according to the specified torque. The pressurizing piston 72 is installed in the pressurizing tube 71. The size of the pressurizing piston 72 should match the inner diameter of the pressurizing tube 71 to ensure that it can slide smoothly and seal well in the pressurizing tube 71. During installation, slowly place the pressurizing piston 72 into the pressurizing tube 71 and ensure that the sealing ring is installed in place without distortion or damage. The pressurizing shaft 73 and the pressurizing piston 72 are fixed together by a threaded connection or other reliable connection method. After connection, check the coaxiality of the pressurizing shaft 73 and the pressurizing piston 72 to ensure that the pressurizing shaft 73 can drive the pressurizing piston 72 to move vertically in the pressurizing tube 71 to avoid deviation that may cause the piston to become stuck or the seal to fail.
