Description

Technical Field

[0001] The invention relates to the technical field of 999 technology, and in particular to a device for extracting proanthocyanidins from alfalfa plants. Background Art

[0002] Proanthocyanidins are a class of polyphenolic compounds widely found in plants. They are polymerized from monomers such as catechins and epicatechins with varying degrees of polymerization. They are mostly dark brown powders in appearance and have strong antioxidant properties. They can efficiently remove free radicals, protect cells from oxidative damage, delay aging, enhance human immunity, and help maintain cardiovascular health and prevent atherosclerosis. They are commonly found in plants such as grapes, blueberries, and alfalfa. After extraction, they are used in health products, food, cosmetics and other industries.

[0003] The extraction of proanthocyanidins from alfalfa plants is to first put the harvested, washed and crushed alfalfa into a suitable organic solvent, then use methods such as immersion, reflux, ultrasound or microwave assistance to dissolve the proanthocyanidins into the solvent, then filter out impurities, concentrate and dry to finally obtain the proanthocyanidin product. During the immersion process, the crushed alfalfa absorbs the organic solvent, resulting in residual proanthocyanidins in the plant, which is easy to cause waste during extraction. Therefore, we proposed a device for extracting proanthocyanidins from alfalfa plants. Summary of the invention

The scraper 345 scrapes the residue entering the gap between the outer shell 2 and the cylinder 31, and gradually sweeps the residue into the residue unloading plate 5. The scraper 345 rotates, driving the cross plate 346 to rotate, and the cross plate 346 sweeps the residue on the top of the cylinder 31. Finally, all the residue is discharged from the residue unloading plate 5.
