Abstract

To produce copra coconut farmers during this drying of fresh coconut in a conventional manner, ie with the sun heating the ground and using a furnace with direct heating fuel from wood or coconut shells. Constraints of the two processes produced copra contaminated with dust and microbe are moldy, temperature / heating temperature can not be determined with certainty.The purpose of this research is to develop a model of mechanical copra dryer type tray dryer and conduct the technical evaluation, analyze the quality of copra is dried with dryer type tray dryer.The results of the technical evaluation of equipment performance earned an average temperature of the drying chamber is 65 0C, the time required for drying the coconut meat with the initial water content of 53.18% to copra with moisture content is 6.84% for 14 hours, and average equipment capacity average to dry the copra is 1.06 kg / hour. From the results of technical analysis on the performance of copra dryers to materials obtained drying rate of 1.0 kg / hour. The energy required to heat the drying air of 2717.08 kJ / h, the energy to evaporate water materials for 2346.20 kJ / hour, the energy generated by the fuel is 12,124 kJ / hour. Gained 22.41% heating efficiency, evaporation efficiency of 86.28%, 19.33% and drying efficiency. From the analysis carried out found that the quality of copra produced quality white colored, clean, and smelled delicious. While the physical form thick and flush with water content ranging between 6-7%.
