step (1) - - -obtaining a slurry: adding water and lower alcohol into selected plant raw materials, putting the plant raw materials into the discharge hopper (3), starting the crushing device (2) for crushing, enabling the crushed materials to flow into the rolling hopper (7), starting the first telescopic cylinder (5) to drive the rolling head (6) to roll and discharge pulp, and dripping the pulp into the liquid receiving tank (10) to obtain slurry;

step (2) - -obtaining a supernatant: injecting an extraction solvent into the slurry in the liquid receiving tank (10) through the first liquid inlet pipe (1001), starting the ultrasonic vibrator (11), and performing oscillation and centrifugation by the aid of the heating device (12) to obtain a supernatant;

step (3) - -automatic extraction of supernatant: the hard infusion tube (15) is moved to a supernatant position, the metering pump (14) is started to extract the supernatant, and the supernatant is discharged into the standing chamber (18);

step (4) - -obtaining the finished product: whether the detection liquid is injected into the standing chamber (18) through the second liquid inlet pipe (181) or not is selected for detection, and if the detection is not needed, the product is obtained by directly utilizing an output pipe (19) arranged in the standing chamber (18) after standing for a period of time.

9. The extraction process according to claim 8, wherein in step (1), the lowering speed of the milling head (6) does not exceed 1cm/s and the number of milling is not less than 10.

10. The extraction process according to claim 8, wherein the heating temperature in the step (2) is controlled to 50 to 80 ℃.
