Title: Utilization of solar energy in grain drying. Final report, June 1978-June 1979

Abstract

Equipment was designed and constructed for use with an existing greenhouse solar drying system (solar barn) to study the utilization of solar energy for peanut curing under the conditions prevailing in North Carolina. The basic equipment consists of a rotary solar drum unit which holds about six tons of peanuts and a trailer unit which transport the drum and peanuts. The unique features of the prototype are that the perforated sheet metal surfaces and the dryer unit itself serves partly as a solar heat absorber/collector during drying mode operation and that the circumferential surface of the rotary drum unit can be disassembled and hung on the drum frame to serve as a ferris wheel plant production system during greenhouse mode operation. The design will provide multi-purpose utilization of the facilities enhancing the economic feasibility of the system. Four full-scale tests were performed for peanut drying using both solar and furnace heating. No-load tests were also performed for system performance study. Computer simulation programs were developed to correlate the measured data and the mathematical model prediction. The heat and mass transfer analysis of solar air heating and grain drying for the prototype model is described and the results of a parametermore » survey showing the effects of various system parameters on drying time are presented.« less
