Through the rotating shaft, the motor can drive the blades to rotate at high speed. When the blades rotate at high speed, they quickly stir the raw materials inside the cylinder and make the raw materials diffuse throughout the interior of the cylinder, thereby quickly mixing the raw materials, thereby improving the mixing efficiency of the raw materials and achieving uniform mixing of the raw materials. After the raw materials are evenly mixed, the first cylinder and the second cylinder pull the first push rod and the second push rod downward respectively, so that the bottom cover moves downward, and then the second cylinder pushes the second push rod upward, so that the bottom cover tilts, so that the evenly mixed raw materials can be discharged, and then the motor drives the blades to rotate slowly, and the blades push the raw materials inside the cylinder to move to the bottom cover to discharge the cylinder, so as to achieve the complete discharge of the raw materials. The discharge plate is convenient for discharging the evenly mixed raw materials, the observation hole is convenient for observing whether the raw materials inside the cylinder are evenly mixed, and the transparent plate and the baffle are to prevent the raw materials from splashing out of the cylinder.
