Description

Technical Field

[0001] The invention relates to the technical field of plant extract fermentation, in particular to a plant extract fermentation device. Background Art

[0002] Plant extracts have extensive and important applications in numerous fields, including food, cosmetics, and medicine. Fermentation technology, as an emerging and highly promising method, is gradually emerging in the field of plant extracts. During the fermentation process, microorganisms secrete dozens of extracellular enzymes, including proteases, cellulases, hemicellulases, amylases, and pectinases, into the culture medium. These enzymes can disrupt plant cell structure, causing cell rupture and increasing intercellular spaces. This significantly reduces the mass transfer resistance of the cell wall and intercellular matrix to the diffusion of plant active ingredients from the cell to the extraction medium, significantly improving the extraction rate of the active ingredients. Furthermore, the fermentation process may also promote the conversion of macromolecules in the plant into more easily absorbed small molecules, thereby enhancing the bioavailability of the extract.

[0003] The stirring rods in existing fermentation tanks are typically positioned at a fixed height. When the liquid level of the fermentation liquid changes, the stirring rods may not fully contact the fermentation liquid, resulting in uneven stirring and affecting the fermentation effect. Furthermore, the fixed-height stirring rods have poor adaptability when handling fermentation liquids of varying volumes, making it difficult to meet diverse fermentation needs. Therefore, it is necessary to propose a plant extract fermentation device. Summary of the Invention

[0004] In view of the problems in the prior art, the present invention provides a plant extract fermentation device.

The lower end of the threaded rod is rotatably connected to a downward pressure rod through a bearing. The rod wall of the downward pressure rod is fixedly connected to a downward pressure block. The interior of the fixed tube is slidably connected to a fixing ring, and a floating sleeve is slidably sleeved on the outer wall of the fixed tube. A floating stirring rod is fixedly connected to the outer wall of the floating sleeve. A sliding hole is opened through the wall of the fixed tube above the stirring rod, and a slider is slidably connected in the sliding hole. The fixing ring, floating sleeve, floating stirring rod and slider are all made of low-density engineering plastics, and the two ends of the slider are fixedly connected to the fixing ring and the floating sleeve respectively.

[0006] Specifically, the drive assembly includes a motor, which is installed on the upper surface of the fermentation tank. The output end of the motor is fixedly connected to a first bevel gear through a coupling. A second bevel gear is fixedly installed on the outer tube wall of the top end of the fixed tube, and the first bevel gear is meshed with the second bevel gear.

[0007] Specifically, the heating assembly includes an annular cavity, which is opened on the inner wall of the fermentation tank outside the reaction chamber, and a heating coil is fixedly installed in the annular cavity.

[0008] Specifically, the feed and discharge assembly includes a feed pipe and a discharge pipe. The feed pipe is fixedly installed at the top of the fermentation tank, and the discharge pipe is fixedly installed at the bottom of the fermentation tank. Solenoid valves are installed on both the feed pipe and the discharge pipe.

[0011] Specifically, the lower surface of the floating stirring rod is arranged in a fitted manner with the upper surface of the stirring rod.

[0012] Beneficial effects of the present invention: When in use, the plant extract fermentation device described in the present invention can drive the lower pressure rod and the lower pressure block to rise or fall by rotating the threaded rod. By controlling the downward pressure of the fixed ring, under the buoyancy of the plant extract in the fermentation tank, the floating sleeve in the liquid drives the floating stirring rod to rise, and until the floating sleeve is against the stirring rod above, thereby increasing the number of stirring rods inside the liquid. More stirring rods rotate under the drive of the motor, which can more fully stir the plant extract, improve the stirring efficiency, promote the uniform distribution of substances in the extract and the metabolic activity of microorganisms, and improve the uniformity of the extract fermentation.

A sliding hole 11 is opened through the tube wall of the fixed tube 3 above the stirring rod 4. A slider 12 is slidably connected in the sliding hole 11. The fixed ring 8, floating sleeve 9, floating stirring rod 10 and slider 12 are all made of low-density engineering plastics (such as polypropylene PP or polyethylene PE), and the interior of the floating sleeve 9 and the floating stirring rod 10 is filled with hard foam filling composite materials to reduce weight and enhance buoyancy. The two ends of the slider 12 are fixedly connected to the fixed ring 8 and the floating sleeve 9 respectively; The drive assembly includes a motor 13, which is mounted on the upper surface of the fermentation tank 1. The output end of the motor 13 is fixedly connected to a first bevel gear 14 via a coupling. A second bevel gear 15 is fixedly mounted on the outer wall of the top end of the fixed tube 3. The first bevel gear 14 meshes with the second bevel gear 15. The heating assembly includes an annular cavity 16, which is opened on the inner wall of the fermentation tank 1 outside the reaction chamber 2, and a heating coil 17 is fixedly installed in the annular cavity 16; The feed and discharge components include a feed pipe 18 and a discharge pipe 19.
