Expanded markets for soybean products have dictated large increases in processing plant capacities. Larger and more sophisticated oil extraction plants are being put on stream by the industry. Lower moisture beans, and in larger volumes, are necessary for the production of high protein meal. Standard grain drier design criteria no longer suffice, a special Soybean Process Drier‐Cooler has evolved. The resulting driers must have a large production capacity while producing bean to bean uniformity with a high degree of reliability and safety. Consideration is given to the physical and chemical characteristics of the bean, to drying concepts and to drier requirements. Rate of moisture migration, allowable air temperatures versus heat tolerance of the bean air flow requirements for moisture removal, and operational as well as safety controls are discussed. Soybean Process Drier‐Coolers of today demand a new perspective of the engineer in predicting capacity requirements, in designing adequate feed and take‐away equipment, and in the location in the processing plant. Fields are currently being explored to assure the processor of the bigger, better drier that will be required.
