step two: after the feeding is finished, a switch of a first servo motor (19) is turned on, an output shaft of the first servo motor (19) drives a rotating rod (15) to rotate, the rotating rod (15) drives a plurality of stirring main rods (16) and stirring support rods (17) to rotate so as to stir the raw materials in the stirring cavity (2), and meanwhile, a rubber scraper (18) rotates to scrape the raw materials attached to the inner wall of the stirring cavity (2);
step three: the switch of a second servo motor (31) is turned on while stirring, the output shaft of the second servo motor (31) drives a conveying auger (27) to rotate, the raw materials positioned at the bottom of the stirring cavity (2) are injected into the conveying cavity (26) through a circulating inlet pipe (28) along with the rotation of the conveying auger (27), and the raw materials are conveyed to the upper part of the conveying cavity (26) through the rotation of the conveying auger (27) and are discharged into the stirring cavity (2) through a circulating outlet pipe (29) to be stirred next time;
step four: after the stirring is finished, the switches of the first servo motor (19) and the second servo motor (31) are closed, the discharge valve (24) is opened, the raw materials in the stirring cavity (2) are discharged from the stirring cavity (2) through the discharge pipe (23), after the raw materials in the stirring cavity (2) are discharged, the switch of the second servo motor (31) is opened, the raw materials remained in the conveying cavity (26) are all discharged from the conveying cavity (26) and injected into the stirring cavity (2) through the rotation of the conveying auger (27), the switch of the second servo motor (31) is closed, and the raw materials in the stirring cavity (2) are discharged through the discharge pipe (23).
