This research aims to design and build solar dryers jasmine. That can be used in household and community level. By the efficiency of solar dryers jasmine. To increase the value of jasmine in the house four houses island cotton farmer Yang high Khanu district. Kamphaeng Phet,
the research found. To build solar dryers jasmine. Dryers that have physical characteristics. Is a drying tunnel 110 cm long, 220 cm wide and 110 cm high with wheels, six wheels can be moved. Jasmine solar dryers contains two main parts: the first part is. Solar Collector (Solar collector) serves to produce heat. Solar Collector has a wide aperture 80 cm long, 100 cm, consisting of cover glass thickness 5 mm plate absorbs solar radiation produced from steel thickness of 5 mm, and then send them to the second is drying room (Dryer) room. dried flowers, dried act. It was a hot wind blowing through the solar collector from the room by using electric fans current (DC) number 3, the front air into the drying flowers. DC fan (DC) power supply from a 20 watt solar panel mounted on the rear of jasmine solar dryers. The drying rack consists of a stainless steel shelf for jasmine. Can move in and out Walls covered with polycarbonate sheets. The structure of the drying machine looks sturdy, insects and dust. And also easy mobility Water well
from testing the efficiency of solar dryers jasmine. By comparing the measured ambient temperature inside the dryer. The maximum temperature was 65.5 degrees Celsius while the maximum ambient temperature at 35.5 degrees Celsius, the maximum 762.8 lux light intensity, humidity and calculation compares the standard of dried flowers. The drying, solar dryers jasmine. A maximum of 526% of the jasmine that the sun is the moisture dry at 163%, when comparing the dryers jasmine solar energy could run faster than the sun up to four times. and yields increased more than ever
in the economic analysis. The value of that investment. When fresh, dried flowers, dried flowers with solar energy will add value to 500 baht / kg, with a payback period of solar drying is approximately two months and three days.
