Research on the application of solar energy to the food drying industry. Final report

Technical Report ·
OSTI ID:7300552
Several solar collector configurations were investigated as to their suitability for drying food crops. Various fruits and vegetables were dried using a mixture of solar energy and steam heat or solar energy alone. Cost estimates (based on initial construction material costs only) indicate that when the price of oil delivered to this country reaches $17 per barrel, then solar energy becomes competitive. An earlier report included in this document consists of results on related tasks including: literature review of dehydrated food industry; current and projected energy demands; projected cost studies for dehydrating carrots and prunes in the years 1975, 1985 and 2000; socio-legal implications; and economic and technical feasibility of solar energy to the food drying industry.
