Abstract
The field practice was conducted to broaden the knowledge and skills of the students and to provide experiences on the activities provided by the Philippine Rice Research Institute (PhilRice) Rice Engineering and Mechanization Division (REMD) on the performance evaluation of a motor-driven brown rice machine. The general objectives of this study were to; evaluate the machine performance in terms of brown rice recovery, head rice recovery, hulling efficiency and hulling capacity; to perform cost analysis on the use of machine; and to compare the performance parameters of motor driven and manually operated brown rice machine in terms of brown rice recovery, head rice recovery, hulling efficiency, and hulling capacity.
Evaluating the performance of the machine in terms of brown rice recovery, head rice recovery, hulling efficiency and hulling capacity in different moisture content (NSIC Rc 222 variety) to determine which parameters can produce best result and computing the cost analysis on the use of machine. And comparing the best result on performance parameters of motor driven and manually operated brown rice machine in terms of brown rice recovery, head rice recovery, hulling efficiency, and hulling capacity. The study was laid out in Complete Randomized Design (CRD). Analysis of Variance (ANOVA) was used to analyze significant difference between treatment means and Comparison Among Means (CAM) was done using LSD at 5% level of significance.
Based on the result, the paddy having 11-12% moisture content level provided the best results while 15-16% moisture content gave the lowest result on all of the parameters of the brown rice machine. The highest mean brown rice recovery, head rice recovery, head rice recovery, hulling efficiency and hulling capacity is 66.1%, 83.41%, 75.23% and 1.9kg/hr, respectively, while the lowest were 64.7%, 82.06%, 72.88% and 1.59kg/hr, respectively. Comparing the best result on performance parameters of motor driven and manually operated brown rice machine in terms of brown rice recovery, head rice recovery, hulling efficiency, and hulling capacity proves that using manually-operated has the better performance than motor driven in all performance parameters of the machine.
