Abstract
Up to 80% of the total energy requirement for malting is represented by air heating in the kilning process. This feasibility study concludes that in a good solar location (Colorado, USA) up to 40% of the kiln heat energy can be supplied by solar collectors simply by passing the intake air through them. By scheduling kiln operation solar heat availability could be maximized. Conventional back up heating would ensure completion under adverse conditions. Some 40% of the heat collected during daytime could be stored by pebble bed unit for night time use. Alternatively, malt partially kilned on one day could be stored overnight for completion on the second day. In general terms, malt kilning is an excellent application of solar energy, providing direct heat, free from combustion products, with no need for heat exchangers. The current cost of solar energy is marginal compared with conventional fuel. Its attractions include its cleanliness, freedom from pollution and its fixed cost over the useful life of the equipment.
