[0023] 1. Through the configuration mechanism, the second motor drives the stirring blade to rotate around the configuration cylinder while simultaneously flipping it. During the mixing process, the steam generator introduces high-temperature steam into the heating plate. The heating plate rotates together with the second rotating shaft to heat the raw materials. When the stirring blade flips the raw materials, it can turn the raw materials from different layers toward the heating plate, thus avoiding local dead corners and ensuring full contact between the raw materials and the heating plate. The tumbling action continuously refreshes the raw material layers, shortening the melting time. The coordinated movement of the heating plate and the stirring blade prevents the raw materials from accumulating on the cylinder wall due to centrifugal force, further enhancing the heat transfer efficiency. Furthermore, the raw materials are continuously transported to the surface of the heating plate, promoting the uniform distribution of components such as wax, pigments, and additives.

[0024] 2. By setting up a preheating conveying mechanism, the motor drives the spiral blades to rotate and convey the prepared raw materials. At the same time, it drives the mixing plate to rotate and quickly stir the high-temperature steam in the insulation pipe evenly. This ensures that the temperature fluctuation range of the raw materials is small during the conveying process, ensures the fluidity of the raw materials, avoids wax phase change, and reduces the viscosity of the raw materials, reducing the residue on the spiral blades and cylinder wall.
