Efficient Temperature-Controlled Conveying Applications of Heat Exchange Screw Conveyors in Chemical Engineering

In chemical production, heat-exchange screw conveyors achieve simultaneous material transport and temperature control through their unique design. A chemical enterprise employed this equipment to handle viscous polymers. By circulating steam or cooling water through the internal channels of the screw blades, the system effectively prevented material caking or degradation caused by temperature fluctuations during conveyance.

The core advantage lies in its integrated design. While material advances through the U-shaped trough propelled by the screw blades, precise temperature control is achieved via the heat exchange medium channels within the hollow shaft and blades. This design not only saves space but also eliminates the process flaws of traditional methods that involve conveying first and heating later, significantly boosting production efficiency.

In practical applications, this equipment demonstrates outstanding performance. For instance, in plastic pellet drying processes, the heat exchange screw conveyor elevates material temperature from ambient to 120°C while simultaneously conveying it, reducing drying time by 40% and lowering energy consumption by 25%. Its sealed structure design also effectively prevents dust leakage, improving the working environment.

Regarding maintenance, the equipment's modular design enables quick and easy replacement of worn components. Feedback from enterprises indicates a 30% reduction in maintenance costs and a 50% decrease in downtime compared to traditional equipment.

This case demonstrates that the heat exchange screw conveyor is an ideal choice for achieving efficient, energy-saving production in the chemical industry, particularly suited for handling temperature-sensitive materials.
