Description

Technical Field

[0001] The utility model relates to the technical field of polysaccharide extraction, in particular to a device for extracting medicinal fungus polysaccharides. Background Art

[0002] The ultrasonic extraction of edible fungus polysaccharides utilizes the high-frequency oscillation, cavitation effect and mechanical shear effect of ultrasound to enhance the mass transfer from solid particles to liquid and promote the diffusion of the extractant to the solid-liquid interface. In addition, the shock waves and jets generated by cavitation can destroy the plant cell wall and cell membrane structure and remove some substances that hinder the contact between enzymes and substrates, thereby increasing the penetration of cell contents through the cell membrane. Solid particles and associated water molecules are also crushed into tiny masses, thereby increasing the dissolution rate of effective ingredients and thus increasing the yield of polysaccharides.

[0003] In the process of extracting polysaccharides from edible fungi by ultrasonic method, some solid particles float on the extract as the ultrasound proceeds, affecting the effect of high-frequency oscillation and reducing the efficiency of edible fungi polysaccharide extraction. Therefore, it is necessary to design an extraction device for medicinal fungi polysaccharides with strong practicality and high extraction efficiency. Utility Model Content
