During the reciprocating motion of the movable frame (10), the guide rod (11) on the end surface of the movable frame (10) can push and pull the lifting rod (17) through the connecting rod (15), so that the blocking block (19) can move up and down inside the feeding pipe (21). When the lifting rod (17) moves downward, the blocking block (19) moves downward as a whole, and a certain gap is generated between the end of the inclined surface with a lower horizontal height and the pipe opening of the feeding pipe (21), so that the raw material can flow out from the gap. When the lifting rod (17) moves upward, the blocking block (19) moves upward as a whole, and the blocking block (19) can push the raw material inside the feeding pipe (21) to the storage hopper. (22), the raw materials are prevented from adhering to the inner wall of the feeding pipe (21), and the device can realize alternating feeding so that the two raw materials can be mixed more fully, the two raw materials are fresh peppercorns and clean water, and pectinase is added to the clean water at a pH of 5.0-5.5, the fresh peppercorns are added to the stirring barrel (1) at a material-liquid ratio of 1:5-1:10 kg / L, 0.1-0.2% w / w pectinase based on the mass of fresh pepper is added to the clean water, the temperature inside the stirring barrel (1) is heated to 50-55°C by a temperature sensor and a heating device, and the stirring is carried out at a speed of 1000-1500 r / min for 2-3 hours to obtain peppercorns; S3. At the same time, under the action of the synchronization rod (24), the driving plate (25) moves up and down synchronously with the lifting rod (17). Through the up and down movement of the driving plate (25), the rack (26) at the end of the driving plate (25) drives the third gear (28) to rotate, and the third gear (28) drives the fourth gear (29) to rotate. Under the rotation of the fourth gear (29), the second stirring rod (30) inside the stirring barrel (1) rotates. Under the rotation of the second stirring rod (30), the raw materials can be transported in the direction of the first stirring rod (7). Finally, the peppercorns and waste liquid can be discharged through the discharge port at the bottom of the stirring barrel (1), thereby realizing the peeling of fresh pepper.
