Description

Technical Field

[0001] The present application relates to the technical field of microbial fermentation, and more specifically, to equipment for microbial fermentation. Background Art

[0002] Microbial fermentation is a process that uses microorganisms to convert raw materials into products needed by humans through specific metabolic pathways under suitable conditions; the fermentation conditions mainly include suitable temperature, pH value, water activity and necessary nutrients.

[0003] In the related art, in order to prevent microorganisms from sticking to the inside of the fermentation equipment, resulting in incomplete fermentation and inconvenience in cleaning, for example, the patent with the prior art publication number CN221371146U provides a microbial fermentation tank that avoids sinking. The device fills the interior of the fermentation tank body with fermented materials through a feed pipe. After the fermented materials are filled, the user closes the feed pipe and then waits for the fermentation process. During the fermentation process, the user can start the first motor and rotate the first motor cam. When the cam rotates, the fermentation tank body can be lifted and then dropped through the connection between the cam and the bearing, so that the fermented materials inside the fermentation tank body vibrate, so that the fermented materials inside can be evenly mixed and fermented, and when unloading, it can also effectively prevent the fermented materials from sticking to the inner wall of the fermentation tank body and making it difficult to unload.

[0004] Although the above-mentioned prior art solution can achieve the effect of uniform mixing and complete fermentation of the fermented products by vibrating the fermentation tank body driven by a motor, when the fermented products are mixed and unloaded by relying on the vibration of the fermentation tank, the cleaning efficiency of the fermented products attached to the inner wall of the fermentation tank is low, which increases the unloading time of the fermented products.

When the equipment is unloading, the driving mechanism 5 is reversed to drive the piston 4 to repeatedly rise and fall in the inner cylinder 2 to discharge the material from the discharge port 21. At the same time, the stirring frame 31 rotates around the inner cylinder 2 to scrape the fermented material on the inner wall of the equipment, thereby ensuring that the equipment can scrape the fermented material attached to the inner wall of the fermentation tank, reducing the unloading time, and increasing the unloading efficiency of the equipment. In addition, during the fermentation process, the fermentation temperature can be adjusted by the cooling plate and the heating plate to ensure smooth fermentation.

[0052] Under the action of the one-way bearing A43, when the connecting tube 54 is reversed, the transmission rod 42 rotates to drive the reciprocating screw 41 to rotate, thereby driving the piston 4 to reciprocate and lift, so that the piston 4 releases the seal on the discharge port 21 through the guide port 45 to discharge the material, wherein the limit groove 44 limits the piston 4 to prevent the piston 4 from rotating.

[0053] Reference Figure 1 , Figure 3 and Figure 6 A bottom shell 46 is fixedly provided at the bottom of the reciprocating screw rod 41 for scraping and cleaning the outer side of the piston 4 . A guide frame 47 is provided on the outer side of the bottom shell 46 , and a slope 48 is provided on the inner side of the guide frame 47 .

[0054] The guide frame 47 blocks the fermented material falling from the guide port 45 to prevent the fermented material from splashing, so that the fermented material falls along the guide port 45 and the inclined surface 48 on the guide frame 47. While the piston 4 is raised and lowered, the bottom shell 46 can scrape the fermented material on the surface of the piston 4.

[0055] Reference Figure 1 , Figure 3 and Figure 7 A detection mechanism 6 is fixedly arranged on the top of the outer cylinder 1. The detection mechanism 6 includes a detection rod 61. A plurality of detection heads 611 are arranged at the bottom of the detection rod 61 for detecting the fermentation conditions in the equipment.

[0056] By lifting and lowering the detection rod 61, the detection head 611 is driven to rise and fall inside the outer cylinder 1 to detect the fermentation conditions such as the temperature and pH value inside the equipment, thereby ensuring the fermentation effect of the equipment.

The bottom of the track shell 66 is fixedly arranged on the top of the outer cylinder 1, and the detection rod 61 is fixedly arranged on the outer side of the track shell 66.

[0058] When the driving motor 51 rotates forward, the transmission column 62 is driven to rotate through the one-way bearing B63, thereby driving the connecting plate 64 and the ball head rod 65 connected thereto to rotate inside the track shell 66, so that the ball head rod 65 drives the track shell 66 to rise and fall, thereby driving the detection rod 61 to rise and fall. When the detection rod 61 descends to the inside of the outer cylinder 1, the stirring frame 31 just passes through the bottom of the detection rod 61, so that the stirring frame 31 and the detection rod 61 will not collide, thereby ensuring the detection effect of the equipment.

The top of the connecting pipe 54 is provided with a feed pipe 73, and the outer side of the feed pipe 73 is provided with a valve 74.

[0064] Liquid material is input through the feed pipe 73, and the material flows into the spray block 71 from the opening 541 through the connecting pipe 54. Under the sealing effect of the sealing ring 711, the material will not flow out. When passing through the outer shell 712, the material is sprayed from multiple nozzles 72, among which the valve 74 can open and close the feed pipe 73, ensuring the normal use of the equipment.

[0065] In summary, when the microbial fermentation device disclosed in the embodiment of the present application is used, the fermentation material is added between the outer cylinder 1 and the inner cylinder 2 through the feed port 12, and the driving mechanism 5 is started to rotate forward through the display controller 11, driving the gear B52 to rotate, thereby driving the gear C53 and the connecting pipe 54 connected thereto to rotate, and the connecting pipe 54 drives the connecting rod 32 to rotate, thereby driving the stirring frame 31 to rotate, and the fermentation material is mixed and stirred. At the same time, the connecting rod 32 drives the stirring frame 31 to rotate, thereby driving the stirring rod 34 to rotate, and the stirring rod 34 rotates under the action of the transmission structure 33 to stir the fermentation material, so that the fermentation material is stirred more fully;

[0066] When the equipment is unloading: the driving mechanism 5 is reversed to drive the gear B52 to rotate, thereby driving the gear C53 and the connecting pipe 54 connected thereto to rotate. Under the action of the one-way bearing A43, the transmission rod 42 rotates to drive the reciprocating screw rod 41 to rotate, thereby driving the piston 4 to reciprocate and lift, so that the piston 4 releases the seal of the discharge port 21 through the guide port 45, so that the material is discharged from the discharge port 21, and the fermented material falling from the guide port 45 is blocked by the guide frame 47 to prevent the fermented material from splashing, so that the fermented material falls along the guide port 45 and the guide frame 47. While the piston 4 is being lifted and lowered, the bottom shell 46 can scrape the fermented material on the surface of the piston 4. At the same time, the connecting pipe 54 drives the connecting rod 32 to rotate, thereby driving the stirring frame 31 to rotate, and scraping the fermented material on the inner wall of the equipment, ensuring that the equipment scrapes the fermented material attached to the inner wall of the fermentation tank, achieving the effect of unloading while cleaning the inner wall, reducing the unloading time, and increasing the unloading efficiency of the equipment.
