Thermal Plastic Dryers

Remove moisture content from processed plastics easily with our range of thermal plastic dryers, perfect for waste to energy and recycling applications.

Operation of thermal plastic dryers

Rotajet manufacture the RDD rotary thermal plastic dryers for the reduction of moisture in plastics during processing. This machine is a rotating Archimedes drum dryer and is an incredibly effective way of dewatering film and rigid plastic materials down to below 0.5%.

Shredded or granulated plastics are typically fed into the Rotajet thermal dryer by an incline conveyor. The dryer is fitted with a high volume air blower to remove moisture from the input material. To increase energy efficiency, the hot air is re-circulated for reuse and maintains the operating temperature in a short time cycle.

Typically the Rotajet RDD thermal dryers are used when very low moisture levels are required or when there is waste heat energy from a plant; the waste heat can be transferred by a heat exchanger into the thermal dryer to maximise energy efficiency.
