Abstract

The hydraulically operated coconut dehusking machine consists of three main parts ie., the frame, the power unit together with hydraulic system, and the dehusking mechanism, Two persons are required to work synchronously, One Operates the machine while the other takes out minor remaining fibrous husk for the shell of the dehusked coconuts and collects them. A 1.5 kilowatts 220 volts electric motor is used for driving a hydraulic pump. The oil is delivered 50 kg/cm2 under working pressure at 14.2 liters/minute to feed the reducing circuit and sequence circuit in order to operate the lifting and dehusking mechanism. The average dehusking speed is 10-12 seconds/coconut. The total cost of operation is about 0.08 baht/coconut which is about half of the price of the conventional dehusking method.
