A technical and economic feasibility study was conducted on the use of solar energy to kiln malt. Solar malt kilning has good economic potential because it requires process heat within flat plate solar collector temperature ranges of 40 to 65/sup 0/C, it is operated 365 days per year, and it is a 12 to 16 hour batch operation. Prior to experimentation a computer model was developed to predict the annual solar energy contribution to the process, given climatic conditions and the specific load requirements. The model gave solar contributions of up to 40% without solar heat storage and up to 75% with the use of storage. The project discussed here addresses the potential for improving the compatability of solar availability and a malt kiln's requirement for energy without the use of heat storage. A small scale pilot unit comprising 6.2 m/sup 2/ of flat plate air heating collector was designed, constructed, and operated between May and September in Golden, Colorado. The system includes an air-to-air heat exchanger to recover waste heat and an auxiliary electric heater together with a fan and the necessary ducts, dampers, and controls. The kiln consists of a cabinet into which malt is loaded to the same depth as in a production kiln. The solar kilned sample of 20 to 50 kg represents a segment or column of malt kilned under comparable conditions as in a 50 ton production kiln.
