[0087] Step 1, soaking the beans that have been screened for impurities and then grinding them, and then filtering the soy milk after the grinding process;

[0088] Step 2, the technician injects soybean milk into the liquid tank 2, and then starts the heating mechanism 3 to heat the soybean milk until the temperature of the soybean milk is within the temperature threshold;

[0089] Step 3: Then start the linear motion part A603 to push the piston plate 604 to perform a vertical linear motion in the box body 601, thereby pushing the coagulant in the box body 601 to be injected into the liquid tank 2 through the injection tube 606. At the same time, the piston plate 604 pushes the push column to slide along the spiral groove provided on the rod body 6051, thereby pushing the two rod bodies 6051 to perform a vertical rotational motion. The rod body 6051 pushes the disk body 6054 to perform a vertical rotational motion. The disk body 6054 The arc-shaped pulley disc 6055 is driven to rotate synchronously by the linear motion part B installed thereon, and the three annularly distributed arc-shaped pulley discs 6055 further drive the rotating shaft 6052 and the sleeve 6053 to rotate in opposite directions in the vertical direction through the elastic belt 6058. At this time, the rotating shaft 6052 and the sleeve 6053 push the two corresponding stirring blades 6057 to rotate in opposite directions in the vertical direction, so as to stir the soy milk injected with the coagulant in the liquid tank 2;

[0090] Step 4: According to the amount of coagulant injected, the linear moving part B is adjusted to push the arc-shaped pulley 6055 to perform linear motion in the horizontal direction, and the radius of the driving end of the elastic belt 6058 is changed to achieve the technical effect of adjusting the rotation speed of the stirring blade 6057;
