Abstract

The objective of this study is to investigate the effects of pressed palm conditions on acceleration of palm drying rate and CPO(Crude Palm Oil)quality. Three pressed palm conditions were dried in hot-air tray dryer, namely(1)conventional palm, (2) slightly-broken palm and (3) fully-broken palm. The velocity of hot airwas fixed at0.7 m/s with hot air temperature of 80 and 100oC. The hot air was blowing through the drying chamber approximately 30 hours as imitate the same condition with conventional drying in factory. The result shows that the drying rate of broken palm is fasterthan the case of conventional palm. Especially,the drying rate of fully-broken palm is the fastest.This expectationcan minimize energy consumption in drying process.ForCPO quality, however, FFAof CPO for the case of the broken palmwas higher than the caseof conventional palmwhichdegrade the CPO quality. The suggestion using this method can be developed and applied in oil palm milling process which is acceptable for getting low CPO quality as oil palm for blending in animal food.
