DEVELOPMENT OF GINGER JUICE EXTRACTOR

Abstract

A small scale motorized ginger juice extractor was designed and fabricated, using locally available construction materials. The essential components of the machine include feeding hopper, ginger grinder, screw conveyor, strainer, pulley and transmission belt, electric motor, base and stand. In operation, the ginger will be fed through the grinder to reduce its size. Then, the worm shaft or screw conveyor conveys, crushes, presses and squeezes the grinded ginger to extract the juice. The juice extracted is filtered through the juice sieve into juice collector while the residual waste is discharged through waste outlet. Result showed that for every 1 kg of ginger the average juice yield was 80 ml. Powered by a 0.5 hp electric motor, the machine has a capacity of 1/2 kg/min. With a machine cost of about P45 000, it is affordable for small-scale ginger farmers in the rural communities.
