8,000 kilograms of dressed poultry are blast-frozen on hand trucks each day (24 hrs) in a freezing tunnel. The poultry is to precooled to 7°C before entering the freezer where it is frozen and its temperature is lowered to -20°C for storage. The specific heat of poultry above and below freezing are 3.18 and 1.55 kJ/kg- °C, respectively. The latent heat is 246 kJ/kg and the freezing temperature is -2.75°C. Neglecting the heat load from the hand trucks, determine the amount of heat needed to be removed from the dressed poultry in kW.
