Design Considerations and Prototype Tests on a Pyrethrum Flow Solar Energy Dryer

This paper describes a prototype solar energy dryer specifically designed to serve the needs of the small scale rural farmer growing pyrethrum. This is a "mixed type" solar energy dryer utilising a flat plate solar collector for air preheating and direct solar radiation on the crops. Prototype test results gave a system crop drying efficiency of 25.8% for the period October 1984 to February 1985.
