The study and improve of drying system coconut oil filter system, solar energy, used in household, agriculture, industrial plants. And in order to evaluate the potential of scraps in creating a full range of coconut oil. The research is dividing into 3 types: drying coconut residue after coconut milk squeezing. Phase one, the control temperature is between 40to50oC. The second phase, the control temperature is between 50to60oC and the third period is the temperature. Controlled between 60to70oC. From the experiment, it was founding that the coconut pulp that was squeezing in coconut milk was deriding at a temperature of 50to 60oC. Coconut oil is cold pressed; the image is multiplying by the standard. The oil sample, which the average production rate uses 4 kilograms of dried coconut residue, 1 liter of virgin coconut oil, which is drying by coconut oil at a controlled temperature between 40 to 50oC. Has a taste of real coconut or has a mild aroma. The drying coconut oil at the controlled temperature is between 50 to 60oC. The color of the oil is white. Has a taste of real coconut or has a mild aroma But the amount of oil obtained is slightly less than the first. The drying coconut oil at the controlled temperature is between 60 to 70oC. The color of the oil is light yellow. With the taste of real coconut or fragrant like roasted coconut As for the amount of oil that is squeezed out, it is less than the first model, averaging about 9.16% and less than the second type, with an average of about 8.79%. 2018-01-01T00:00:00Z http://localhost:8080/xmlui/handle/123456789/1189 Develop thermal efficiency of hot air solar selective surface to promote used solar energy for sea-food drying Chanon Bunmephiphit; Nuchjira Dejang; Tawat Suriwong The objective of this research applying black spray color in local market, it is flat-black color, don’t mixing reflection chemical for coating solar selective surface to make up hot-air solar color. Research mythology was standard process for coating surface by spraying and testing thermal efficiency The result 1. The solar selective color and solar absorptance was 0.98 2. The surface was roughness, do not reflection solar radiation out of surface 3 . The highest thermal efficiency was 0.81 and the term of energy loss ( - FR) was18.38 W/m2.°C 2018-01-01T00:00:00Z http://localhost:8080/xmlui/handle/123456789/351 Biogas Production from Food Waste and Vegetable Waste for the Sakaew Temple Community Angthong Province Kodchasorn Hussaro; Chanida Jantree; Issaree Hunsacharoonroj; Pongsakorn Kerdchang The objective of this research is to fine the method for biogas production from food waste with vegetable waste. To study economic analysis of biogas production and management of residue waste to the renewable energy for the benefit of community life. Including to publishing and technology transfer to the community. For the method in this research were consisted of 4 methods, which is were survey of food waste to the community, design and set up biogas production system, the fermentation experiment to find the optimum condition, and technology transfer to the community. Biogas production was operated in 200 liter of digester for 40 days. During this research process, the materials for biogas process were mixed in the 5 different ratios of food waste with vegetable waste : chicken dung as following; 1 : 1 (Digester D3), 2 : 1 (Digester D4) , 3 : 1 (Digester D5), 1:0 (Digester D1), and 0 : 1 (Digester D2). From this result, it was found that the ratio of food waste to chicken dung to 1:1 (Digester D3) had provided the highest amount of biogas, which was 18.83 kg and the highest methane content gas were 72 %. The carbon to nitrogen ratio, temperature digester, and pH at digester D3 were 18.83, 29.8 ºC, and 6.87, respectively. After calculating economic internal rate of return, it was found that the payback period was 16.4 days for digester D3. The results of satisfaction evaluation for technology transfer to the Sakaew Temple Community Angthong Province shown that participants have satisfied the most level. 2016-08-01T00:00:00Z
