In the step c, an operator starts a second driving motor 604 of the feeding structure 6, the second driving motor 604 drives a hollow rotating shaft 610 to rotate through a hexagonal inserted bar 611, the hollow rotating shaft 610 drives materials passing through the filter plate 703 to enter a second blanking pipe 602 and then enter the stirring tank 1, then a first driving motor 5 is started, the first driving motor 5 drives a stirring shaft 11 to rotate, the stirring shaft 11 drives a stirring plate 8 to rotate, the stirring plate 8 drives a first inclined plate 9 and a second inclined plate 12 to rotate, the directions of the first inclined plate 9 and the second inclined plate 12 are opposite, the material stirring speed is increased, the production efficiency is improved, meanwhile, the stirring plate 8 drives a scraping plate 10 to rotate, the scraping plate 10 is convenient to clean the materials on the inner wall of the stirring tank 1, the materials are prevented from being bonded on the inner wall of the stirring tank 1, and the cleanliness of the stirring tank 1 is guaranteed;

the fixing bolt 607 of the feeding structure 6 fixes the insert sleeve 606 and the insert block 608, so that the cover plate 609 is convenient to assemble and disassemble, the hollow rotating shaft 610 is convenient to install on the hexagonal insert rod 611, the cover plate 609 is convenient to drive the middle idle shaft 610 to assemble and disassemble in the feeding barrel 601, and the hollow rotating shaft 610 is convenient to replace.

And d, adding water into the stirring tank 1 for continuous stirring for 350-420 s.
