Abstract
Description
Technical Field
[0001] This utility model relates to the field of edible fungi polysaccharide extraction technology, specifically to a stirring device for edible fungi polysaccharide extraction. Background Technology
[0002] Edible fungi polysaccharides are a special class of bioactive substances, acting as biological response enhancers and regulators with multiple functions such as boosting immunity and antioxidation. Our team's research revealed that the current production of edible fungi polysaccharides involves a large amount of waste. For example, shiitake mushrooms are mostly extracted from their fruiting bodies rather than their stems, and Poria cocos is extracted from the dried sclerotia of Poria cocos (Schw.) Wolf. Poria peel and its outer layer are discarded as industrial "waste" after processing, resulting in waste. It has been reported that tens of thousands of tons of Poria peel are generated annually during Poria processing. The waste composition is complex, with some sugar extracts exhibiting low activity, and the yield and purity of high-activity polysaccharides being low. Using conventional stirring devices for extraction has the following drawbacks: most are single, fixed stirring blades, making it impossible to adjust the blade morphology, leading to poor stirring effects. Furthermore, residue easily accumulates on the inner wall of the device, and there is no corresponding cleaning structure to clean the inner wall, affecting subsequent use. Therefore, we propose using a stirring device for edible fungi polysaccharide extraction to solve the above-mentioned problems. Utility Model Content

[0013] (III) Beneficial Effects
[0014] Compared with the prior art, the present invention provides a stirring device for extracting polysaccharides from edible fungi, which has the following beneficial effects:
[0015] This stirring device for extracting polysaccharides from edible fungi is widely applicable and can efficiently extract highly active polysaccharides from edible fungi scraps. By incorporating a stirring mechanism and a cleaning mechanism, a drive motor rotates a rotating rod, causing the stirring blades and cleaning mechanism to move. A return spring pushes a locking block into a rectangular groove on a vertical plate, fixing the slider position, and the stirring blades are horizontally extended. When the angle of the stirring blades needs adjustment, pressing the pressure block pushes the push rod to the left, moving the baffle and compressing the return spring. The push rod then pushes a right-angle plate, causing the locking block to disengage from the vertical plate. Manually moving the slider up and down causes a swing plate to oscillate via a connecting rod, adjusting the angle of the stirring blades. Releasing the right-angle plate releases the return spring, causing the locking block to re-engage and lock the angle, thus achieving adjustable stirring blades. A fixed cylinder is connected to a cleaning roller via a mounting rod, rotating synchronously with the rotating rod. The cleaning roller adheres tightly to the inner wall of the processing cylinder, scraping away materials adhering during stirring, avoiding manual cleaning during machine downtime, improving production continuity, and achieving the purpose of the cleaning structure.

[0033] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0034] In summary, this stirring device for extracting polysaccharides from edible fungi, by setting up a stirring mechanism 6 and a cleaning mechanism 7, drives the motor 601 to drive the rotating rod 602 to rotate, which in turn drives the stirring blade 607 and the cleaning mechanism 7 to move. The return spring 616 pushes the locking block 614 into the rectangular groove of the vertical plate 610, fixing the position of the slider 604. The stirring blade 607 is horizontally extended. When it is necessary to adjust the angle of the stirring blade 607, pressing the pressure block 612 pushes the push rod 611 to the left, the baffle 615 moves and compresses the return spring 616, the push rod 611 pushes the right-angle plate 613, causing the locking block 614 to disengage from the vertical plate 610. The slider 604 is manually moved up and down, which drives the swing plate 605 to swing through the connecting rod 608 to adjust the stirring. The angle of blade 607 is adjusted, releasing the right-angle plate 613. The reset spring 616 causes the locking block 614 to re-engage and lock the angle, thus achieving the purpose of adjustable stirring blades. The fixed cylinder 71 is connected to the cleaning roller 73 through the mounting rod 72 and rotates synchronously with the rotating rod 602. The cleaning roller 73 is in close contact with the inner wall of the processing cylinder 42 to scrape off the material adhering during the stirring process, avoiding manual cleaning during machine stoppage, improving production continuity, and achieving the purpose of having a cleaning structure. This solves the problem that most stirring blades are single and fixed, which cannot adjust the shape of the stirring blades, resulting in poor stirring effect and easy residue on the inner wall of the device. Without a corresponding cleaning structure to clean the inner wall, it affects the next use.
