[0002] Microbial fermentation has wide applications in modern biotechnology, pharmaceuticals, food, and many other fields. After the microbial fermentation process is complete, the fermentation products need to be extracted.

[0003] Chinese Patent CN222455011U discloses a novel microbial fermentation extraction device, comprising a fermenter and a filter tank. The filter tank contains two sets of circular support frames, each with a fixed circular plate at its center. This invention enables the activation of a primary motor via a control panel. The motor's output drives a transmission wheel, which in turn drives a driven wheel. The driven wheel's rotation causes two sets of cleaning scrapers to continuously clean the surfaces of filter screens one and two, effectively removing fermentation residue from these screens and preventing clogging of the mesh, thus improving the efficiency of microbial sample extraction.

[0004] Regarding the aforementioned technologies, this device has some shortcomings. In actual use, the stirring mechanism is difficult to achieve uniform stirring, resulting in insufficient contact between microorganisms and the culture medium, which affects the fermentation effect and reduces the yield and quality of fermentation products. Therefore, it is necessary to provide a microbial fermentation extraction device to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a microbial fermentation extraction device to solve the problems mentioned in the background art.

[0017] 1. This utility model utilizes the combined use of a fermenter, support legs, feed pipe, vent pipe, track, connecting block, hydraulic telescopic rod, toothed plate, stirring shaft, heating plate, spiral blades, fixing frame, gears, and slider. Activating the hydraulic telescopic rod causes the gears to rotate in both directions, which in turn drives the stirring shaft, which in turn causes the spiral blades to rotate. Due to the spiral structure of the spiral blades and the continuous switching between forward and reverse states, the material inside the fermenter circulates vertically, achieving uniform stirring and effectively increasing the contact between microorganisms and the culture medium, further improving fermentation efficiency and product quality. Simultaneously, the controllable heating plate allows for temperature adjustment within the fermenter to meet the fermentation needs of different microorganisms, enhancing the functionality of the fermenter.

[0018] 2. This utility model utilizes a connecting column, filter box, liquid outlet pipe, mounting port, filter plate, sealing plate, discharge pipe, and valve in conjunction. After fermentation, opening the valve allows the fermentation liquid to flow into the filter box through the discharge pipe. The filter plate performs solid-liquid separation, and the liquid is discharged through the liquid outlet pipe. The filter plate is detachable; when not in operation, releasing the lock and pulling the sealing plate allows the filter plate to be pulled out from the mounting port. This simple disassembly method facilitates efficient cleaning of solid residues on the filter plate, ensuring thorough cleaning, maintaining good filter plate permeability, and demonstrating high practicality.

A gear 21 is fixedly installed at the top end of stirring shaft 17.

[0028] The top of the fermenter 1 is fixedly installed behind the stirring shaft 17 with a track 5. A slider 22 is slidably installed on the track 5. A toothed plate 8 is fixedly installed on the top of the slider 22, and the toothed plate 8 meshes with the gear 21.

[0029] A drive mechanism is located at the top of fermenter 1 behind track 5, a feed pipe 3 is located at the front of the top of fermenter 1, and a discharge pipe 15 is located at the bottom of fermenter 1.

[0030] A connecting column 9 is fixedly installed on the outer wall of the support leg 2. The filter box 10 is fixedly installed on the support leg 2 through the connecting column 9. The bottom end of the discharge pipe 15 passes through the top of the filter box 10 and is connected to the inside of the filter box 10. An installation port 12 is opened on the back of the filter box 10. A filter plate 13 is slidably inserted into the filter box 10 through the installation port 12. A sealing plate 14 is fixedly installed on the back of the filter plate 13. A locking buckle is provided at the connection between the sealing plate 14 and the back of the filter box 10. A liquid outlet pipe 11 is fixedly inserted into the bottom of the filter box 10, realizing solid-liquid separation of the fermentation liquid.

[0031] In one embodiment, a vent pipe 4 is fixedly installed on the top of the fermenter 1 on one side of the feed pipe 3, which can introduce gas as needed to meet the requirements of the fermentation gas environment.

[0032] In one preferred embodiment, a heating plate 18 is fixedly installed on the inner surface of the fermenter 1, which can flexibly adjust the temperature inside the tank to adapt to the fermentation needs of different microorganisms and improve fermentation efficiency and product quality.

[0033] In one embodiment, the drive mechanism includes a fixed frame 20, which is fixedly installed on the top of the fermenter 1 behind the track 5. A hydraulic telescopic rod 7 is fixedly installed on the fixed frame 20, and a connecting block 6 is fixedly installed on one side of the back of the toothed plate 8. The connecting block 6 is fixedly connected to the drive end of the hydraulic telescopic rod 7, which can drive the toothed plate 8 through the hydraulic telescopic rod 7. The fixed frame 20 ensures stable installation, and the connecting block 6 achieves reliable connection, providing stable power for the rotation of the stirring shaft 17 and the stirring of materials.

[0034] In one preferred embodiment, a valve 16 is provided on the discharge pipe 15, which can flexibly control the flow rate and on / off state of the fermentation liquid flowing from the fermentation tank 1 into the filter box 10, so as to accurately control the fermentation and separation process.

[0035] The working principle of this utility model is as follows: All electrical components mentioned are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer for control, and existing publicly available power connection technologies are not elaborated here. Parts not mentioned in this device are the same as or can be implemented using existing technologies. In use, microbial inoculum and culture medium are first introduced into the fermenter 1 through the feed pipe 3, followed by the introduction of sterile air through the vent pipe 4. The hydraulic telescopic rod 7 is activated, and its drive end, via the connecting block 6, drives the toothed plate 8 to perform a lateral reciprocating motion. During this process, the toothed plate 8 drives the slider 22 to slide on the track 5, thereby ensuring the stability of the lateral movement of the toothed plate 8. Based on the meshing action between the toothed plate 8 and the gear 21, the gear 21 achieves forward and reverse rotation. The rotation of the gear 21 then drives the stirring shaft 17 to rotate, which in turn causes the spiral blades 19 to rotate. Given the spiral structure of the spiral blades 19 and their continuous switching between forward and reverse rotation, the material inside the fermenter 1 circulates vertically, achieving uniform mixing and effectively increasing the contact between microorganisms and the culture medium, thereby further improving fermentation efficiency and product quality. Simultaneously, the controllable heating plate 18 regulates the temperature inside the fermenter 1 to meet the fermentation needs of different microorganisms, enhancing the functionality of the fermenter 1.

[0036] After fermentation, valve 16 is opened, and the fermentation broth flows into the filter box 10 through the discharge pipe 15. The filter plate 13 inside the filter box 10 performs solid-liquid separation on the fermentation broth, and the separated liquid is discharged through the liquid outlet pipe 11. For the solid residue trapped on the filter plate 13, when the device is not in operation, the lock between the sealing plate 14 and the filter box 10 is released, and the sealing plate 14 is pulled outwards to move the filter plate 13. The filter plate 13 can then be pulled out of the filter box 10 through the installation port 12 to clean the solid residue on the filter plate 13. The filter plate 13 is detachable and easy to disassemble, which facilitates efficient cleaning of the filter plate 13 by the staff. This direct disassembly cleaning method ensures the thoroughness of the cleaning of the filter plate 13, maintains good permeability of the filter plate 13, and has high practicality.
