The linkage assembly includes a driven bevel gear sleeved on the outer periphery of the fixed shaft, a linkage shaft 21 rotatably mounted on the outer periphery of the rotating shaft, and a fixed gear ring 20 fixed to the bottom surface of the mounting frame 4. The fixed gear ring 20 is coaxially arranged with the rotating shaft 7, the linkage shaft 21 is located on the inner side of the fixed gear ring 20, and the outer circumference of the linkage shaft 21 is sleeved with a linkage gear 22 meshing with the inner ring of the fixed gear ring 20, and the bottom of the linkage shaft 21 is fixed with an active bevel gear meshing with the driven bevel gear. When the rotating shaft 7 rotates, it will drive the winding mechanism 8 to rotate with it, while the fixed gear ring 20 does not rotate, so that the linkage gear 22 rotates while following the revolution of the rotating shaft 7, and then drives the fixed shaft 803 to rotate, so that the two winding rods 801 rotate while following the revolution of the rotating shaft 7, so that the solidified tofu skin on the inner surface of the cooking pot can be rolled up to prevent it from being mixed in the soy milk.

[0053] The implementation principle of this embodiment is as follows: when boiling soybean milk, pour soybean milk into the boiling pot 1, and ensure that the top surface of soybean milk not only covers one of the coiling rods 801 but also does not contact the bottom surface of the suction tube 6, and then turn on the heating device in the heating layer 2 to heat the boiling pot 1, and while heating, start the transmission motor to drive the rotating shaft 7 to rotate, and after the rotating shaft 7 rotates, it drives the stirrer to stir the soybean milk in the boiling pot 1;

[0054] When the shaft rotates, the suction pipe 6 and the transmission shaft 18 are driven to rotate, and then the fan 17 is driven to rotate. When the fan 17 rotates, suction is generated, so that the floating foam in the cooking pot 1 is sucked into the suction pipe 6 through the suction hole 19. Then, the floating foam in the suction pipe 6 enters the shaft 7 through the connecting pipe, and finally falls into the collection tank 13.

[0055] As the rotating shaft 7 rotates, it drives the winding mechanism 8 to follow its revolution. Since the fixed gear ring 20 does not rotate, the linkage gear 22 will rotate under the action of the fixed gear ring 20 while following the revolution of the rotating shaft 7, thereby driving the fixed shaft 803 to rotate while following the revolution of the rotating shaft 7, thereby driving the two winding rods 801 to rotate while revolving, so that the solidified tofu skin on the inner surface of the cooking pot can be rolled up to prevent it from being mixed in the soy milk.

[0058] The implementation principle of this embodiment is: when discharging, the cooking pot 1 is tilted, and the soy milk in the cooking pot 1 is discharged from the discharge port 10, and then discharged to other external containers along the guide plate 9 for cooling.

[0059] Embodiment 3:
