Abstract

The study was conducted to design, fabricate and evaluate the performance of the mechanical calamansi juice extractor. The Philippine Agricultural Engineering Standards for Multi-crop Juice Extractor Method of Test was used to evaluate the device’s performance. The device was tested and evaluated using locally grown calamansi in the province of Bataan. Performance parameters such as extraction rate, juice recovery, extraction efficiency, and machine capacity as affected by varying speed of presser unit (300 rpm, 350 rpm, 450 rpm) were evaluated. A 9-kilogram sample was used in each treatment with three replications. Data were analyzed using factorial design in a Completely Randomized Design (CRD) and comparison among means was tested using Duncan’s Multiple Range Test. Results of the performance test showed that the mechanically operated calamansi juice extractor machine had juice recovery of 16.30%, test material recovery 61.88%, extraction rate of 1.94 kg/hr and extraction recovery of 51.77%, extraction losses of 48.23%, extraction efficiency 36.38% and machine capacity of 12.16kg/hr. And the machine had an investment cost of Php 9,872.80, the calamansi juice extractor custom rate was Php. 4.02/kg at operating cost of Php 4.00/kg.
