The utility model relates to the technical field of extraction devices, and discloses a
phellinus igniarius combined
polysaccharide extraction device which comprises a box body, the top end of the box body is fixedly sleeved with a feeding
pipe, and the bottom end of the feeding
pipe is fixedly sleeved with a primary crushing cylinder; through the flow design of multi-stage crushing, vibration screening and circulating treatment, the
phellinus igniarius is crushed twice by the first crushing cutter and the second crushing cutter, coarse crushing is converted into fine crushing, the particle size of materials can be fully reduced, high-quality raw materials are provided for subsequent
polysaccharide extraction, the extraction efficiency is remarkably improved, and the production cost is reduced. Then, a double-groove belt wheel drives a
cam on a transmission shaft through a second belt, a screening plate vibrates, screening holes are effectively prevented from being blocked, it is ensured that the screening process is smooth, the screening efficiency is improved, it is ensured that the particle size of discharged materials is uniform, and finally unqualified large-particle materials are conveyed back to the primary crushing
barrel through an
auger and a conveying
pipe in the feeding box to be circularly treated. The particle size of the finally discharged material reaches the standard, the
raw material quality is guaranteed, and the
polysaccharide extraction effect is stabilized.
