The invention discloses a
polygonatum polysaccharide extraction device, and relates to the technical field of
plant substance extraction. The problem that the filtering efficiency is poor is solved. The device specifically comprises a tank body and further comprises a top cover fixed to the top end of the tank body through bolts, a stirring rod arranged at the bottom end of a vibrating structure, stirring blades fixed to the outer side of the stirring rod, a liquid outlet fixed to one side of the bottom end of the bottom cover, and a separation structure arranged in the tank body. Large-particle impurities are intercepted through the coarse filter screen, then fine chippings are intercepted through the fine filter screen, meanwhile, a stirring rod drives a scraping plate and a
brush to rotate synchronously, the surfaces of the two filter screens are swept and cleaned, and therefore the efficient filtering function of the device is achieved, the filtering efficiency of a
polygonatum sibiricum
polysaccharide extracting solution is improved, and the filtering effect of the
polygonatum sibiricum
polysaccharide extracting solution is improved. Meanwhile, the surfaces of the two groups of filter screens are automatically cleaned, so that the filter screens are prevented from being blocked, smooth circulation of an extracting solution is guaranteed, continuous and stable operation of the device is maintained, and manual cleaning frequency and maintenance cost are reduced.
