Cichoric acid extraction device

The utility model discloses a chicoric acid extraction device, which belongs to the technical field of traditional Chinese medicinal material production equipment and comprises a spiral squeezing mechanism, a juicing component and a driving oil cylinder. Wherein a piston screw rod is inserted into the top of the spiral squeezing mechanism, the piston screw rod extends into a cylindrical inner cavity of the spiral squeezing mechanism, and the side part of the juicing component is communicated with an inlet of the circulating feeding device through a discharging assembly, so that a material returning circulation is formed. During use, the piston screw rod can crush raw materials and convey the crushed raw materials into the juicing component to squeeze juice, then residual residues enter the spiral squeezing mechanism again through the circulating feeding device, and ethyl alcohol is used as an extracting agent to continue squeezing. On the basis, the plant residues can be circularly squeezed for multiple round
