Heat Pump Rotary Dryers 

Kerone engineers the internal flight design, drum slope and rotation speed of its Heat Pump Rotary Dryers around the specific bulk density, particle size range and cascading behaviour of your material, since flight geometry that works well for one bulk material can produce poor material lift and uneven exposure to air for another. Our team calculates residence time and drum sizing based on your required throughput and moisture removal target, and validates cascading behaviour through trials or detailed engineering review before the drum is fabricated. Kerone’s integration of the heat pump circuit with the rotary drum’s air handling system is designed to work with the dust loading and particulate carryover typical of rotary drying, including appropriately sized cyclone or filter separation ahead of the heat pump evaporator coil to prevent fouling. With five decades of experience building rotary thermal processing equipment for Indian and international bulk material processors, Kerone brings proven mechanical drum design, bearing and drive selection to a technology that lives or dies on mechanical reliability under continuous duty. Kerone also pays close attention to seal design at the drum inlet and discharge points, since air infiltration through poorly sealed rotary joints is a frequent source of both energy loss and reduced heat pump dehumidification effectiveness in rotary drying systems.
