The technical feasibility of pneumatic drying for coconut meat particulates through modeling and simulation procedures was investigated. A thin-layer drying experiment was conducted to determine the drying constants for a temperature range 70-110 deg C, particle size range 1.6 - 2.4 mm and initial moisture content range 53-41%. The drying constants of the Exponential Model were highly influenced by the particle size and initial moisture content of the sample but not by the drying air temperature. The predicted retention time and energy consumption were in agreement with validated values. The drying time for a particle size of 1.6 mm, 105 deg C air temperature, 43 to 50% initial MC [moisture content] and 6% final MC was about 4 to 5 minutes with specific thermal energy consumption of 7.5 KJ per kg water removed. Electrical energy consumption of the system was 1.9 kWhr/1 kg.
