Combination of heater and chiller for melting mixing process

1.The heater is mainly used to heat the raw materials to a molten state. For example, in plastic processing, screw extruders are equipped with electric heating coils or resistance wire heating elements to ensure that polymer raw materials can reach the temperature of molten flow.

2.The chiller plays a role in cooling and solidifying molten materials or adjusting the process temperature. For example, in an extrusion production line, after the molten material passes through the mold to form a product, it will be rapidly cooled by a water or air cooling system for easy shaping and subsequent processing.

In some complex melting and mixing processes, heating and cooling may alternate between different parts of the same equipment, or achieve step-by-step temperature changes by connecting multiple devices in series. For example, in some continuous reaction processes, the material may first be melted and mixed in the heating section, and then immediately enter the cooling section to control the reaction rate or avoid adverse reactions caused by overheating.

In addition, some special melting and mixing equipment may also be equipped with advanced temperature control systems, which monitor and adjust the output of heating and cooling systems in real time through technologies such as sensors and PID controllers, ensuring that the material always stays within the ideal temperature range, thereby optimizing product quality and production efficiency.
