The present study investigated the kinetics of heat pump drying of cocoa beans under stepwise drying conditions and the heat and mass transfer analysis carried out using 3-D computer simulation. The fermented cocoa beans were subject to drying at constant temperature (56 °C), step up temperature (30...
