The first step in producing a cinnamon glazed coconut chips is placing the coconut meat in a P&S dryer. Supposed that the dryer processes 7,777.77 kg of desiccated coconut per hr. The coconut meat are to be dried from an initial moisture content of 20% at 21C to a final moisture content of 1.5 % at 38C. Air enters the dryer at 20% relative humidity and dry bulb temperature of 71C. The barometer reading is at 89.6 kPa. If the specific heat capacity of the coconut meat is 0.754 kJ/ kg-K' and the density of the coconut meat from the shearing and washing section as determined from the pilot testing is 1.520 kg/m3 . Calculate : (A) mass of the water evaporated, (B) total heating requirement of the system. During the calculation of your heating duty, you will notice that there are negative values of heat. Use the negative values of heat and account the min the calculation of your heating duty.
