Heat Pump Paddle Dryers 

Kerone engineers the paddle or disc geometry, shaft rotation speed and trough length of its Heat Pump Paddle Dryers specifically around the rheology of your material as it transitions from wet cake through the sticky, transitional phase to dry, free-flowing product, since this phase transition is where most paddle dryer failures occur if the equipment is not designed for it. Our team draws on process trials with customer material samples to confirm heat transfer rates, torque requirements and residence time before finalizing the design, since undersized drive systems and inadequate heating surface area are common causes of underperformance in poorly specified paddle dryers. Kerone’s integration of the heat pump heating circuit into the paddle shaft and trough jacket design is engineered to deliver stable, controllable surface temperatures across the full length of the trough, rather than a single uniform temperature that ignores the very different heat transfer needs of wet feed material versus nearly-dry discharge material. With decades of thermal processing experience across sludge, chemical and food-processing byproduct handling, Kerone understands the mechanical robustness needed to run paddle equipment continuously on abrasive or corrosive materials. Kerone also specifies wear-resistant paddle tip and trough lining materials appropriate to the abrasiveness of your specific material, recognising that sludges and mineral-bearing pastes can accelerate wear on standard carbon steel surfaces far faster than typical process design assumptions would suggest.
