The Construction of Solar Energy Brown Rice Milling Polishing Machine for Community

Abstract

       The purposes of this research were to : 1) build an efficient  solar energybrown rice milling machine for community 2) assess the quality of  solar energy rice milling machine for community 3) produce electricity from solar energy 4) increase performance energy  5) study the  satisfaction of the farmer with  solar energy rice milling machine for  community. The sample group was 10 farmers from Yangchumnoi Villege, Yangchumnoi Subdistrict, Sisaket Province. Two research instruments were used. They were : 1) quality evaluation form for the experts, and 2) satisfaction questionnaire for the farmers. The research data were analyzed by descriptive statistics ; percentage, mean and standard deviation. From the research findings, it was found that : 1) efficiency of milling brown rice in one hour yielded 20 kilograms of brown rice.  2) the assessment of the quality of 9 experts’ attitude towards solar energy brown rice milling machine found that, average total at 4.38 were good, the material was with an average at 4.60 were very good, the use of brown rice was with an average at 4.40, the properties of brown rice from community had average at 4.33, and the suitability of invention in the field of design was with an average at 4.20, were  good with means value at 4.40, 4.33 and 4.20, 3) to generate electricity from sunlight by using 300 w two solar panels, 100 percent of solar could generate electricity at 3,600 w/day. 4) in terms of energy storage of batteries, the capacity of 2 power-packed 12 V 35 A batteries spent 1 hour and 40 minutes to charge solar panels. 5) satisfaction of the 10 farmers with the use of  solar energy brown rice milling machine found that average total at 4.39 were good, the use of brown rice was with an average at 4.50,the properties of brown rice milling machine was with an average at 4.40, the suitability of invention in the field of design was with an average of 4.37,material was with an average at 4.30, were good with means value at 4.50, 4.40,4.37 and 4.20.
