Rumtoo High-Efficiency Centrifugal Dryer: The Ideal Choice for Plastics Recycling Pre-Drying

Introducing the Rumtoo Centrifugal Dryer – a highly effective, low-energy drying solution engineered specifically for the plastics recycling industry. It utilizes powerful centrifugal force to significantly remove surface moisture from washed plastics (like PE film, PET flakes), making it an indispensable component in modern plastic washing and recycling lines.

Working Principle: Combining Centrifugal Force & Friction Cleaning

Rumtoo’s horizontal centrifugal dryer operates similarly to a high-speed friction washer. At its core, a robust central shaft equipped with multiple wear-resistant paddles spins at high speed (typically over 1000 RPM) inside a precision-engineered mesh screen tunnel. The entire rotating assembly is housed within a sturdy metal enclosure and driven by an efficient external electric motor.

As wet plastic flakes or film enter the machine via the inlet, the rapid rotation of the shaft generates intense centrifugal force. This force throws the plastic material against the inner wall of the mesh screen. Water attached to the plastic surface is effectively separated by this force, passing through the screen openings and collecting at the bottom of the unit for discharge, facilitating easy water recovery or disposal.

After processing through the centrifugal dryer, the moisture content of the plastic is significantly reduced from high levels (post-washing) down to approximately **20%-30%**. This pre-drying step creates an optimal condition for subsequent thermal drying processes (e.g., hot air drying systems), drastically reducing the energy consumption and time required for final drying. Notably, the high-speed paddles also provide a degree of friction cleaning as they tumble the material, helping to further remove contaminants and cool the plastic, achieving the dual benefits of dewatering and enhanced cleaning.
