This research is intended to design and construction of solar dryers haengdok Mali that can be used in the household and community level. To do this, find the performance of solar dryers haengdok Mali, in order to increase the value of the jasmine in the area, villagers are farmers. Ban Ko Fai Road, Tambon Yang Moo 4 high. Amphoe khanu woralaksaburi kamphaeng Phet province.From this research it was found that the creation of solar dryers haengdok Mali. Dryers that have a physical feature is the wind tunnel dryer 110 cm width, length 220 cm and 110 cm high wheel 6 wheels can be moved. Jasmine haengdok Solar dryer consists of two main sections, the first section is a solar (Solar collector), acting in the production of hot air. The solar space is 80 cm, length 100 cm breadth getting consists of a thick sheet of glass is closed. 5 mm sheet steel solar made from absorb a 5 mm thick and then sent to part 2 (Dryer) is dried, drying room, serve baked haengdok Mali, which has been a hot breeze blew through the solar to take advantage by using the DC fan. (DC) 3 front blower into the sauna haengdok Mali. Electric fan (DC) power from the solar panel size: 20 Watt installed, the rear of the dryer, solar haengdok Mali. A drying room consist of stainless steel for the Kae Ta project wangdok Mali. Can move in and out. Lining the walls with sheets of dry carbonate structure looks rugged protection against insects and dust and are easy to move. Water protection. From the test, find the performance of solar dryers haengdok Mali measured ambient temperature compared with the temperature in the drying machine. The highest temperature stood at 65.5 degrees Celsius while maximum ambient temperature is at 35.5 degrees Celsius, which is the maximum light intensity value and calculated 762.8 compared to standard moisture content, drying of jasmine. Through drying with solar energy haengdok Mali The maximum value is 526% best jasmine through how Sun will have moisture and dry standardized is at 163% so when comparing haengdok Mali discovered that solar dryers can perform faster how to hang up to 4 x and makes more than output.In the economic analysis. The result value investment showed that when fresh Jasmine through the drying with solar energy, haengdok, jasmine, will add value to 500 baht per kilogram, which is a period of payback of Solar dryer about 2 months, the 3 days.
