Excerpts from the report: The increasing number of mechanical dryers being used by Kansas elevators pointed up the need for an economic study of their practices, costs, advantages, and disadvantages. An earlier report presented results of a survey, made jointly by Farmer Cooperative Service and Kansas State University, of all Kansas elevators with dryers in August 1957. That report described artificial drying and included a brief discussion of costs. Its emphasis was on general management considerations. This report is based on data collected from 11 local elevators, nine of them cooperatives, included in the original survey. It analyzes costs, factors affecting costs, and returns from drying grain. Sizes and types of dryers, and layouts and installations are discussed, as well as the farmer's problems in deciding whether to harvest wet grain and the elevator's problems in deciding how to dispose of it. Elevator operators contemplating installing dryers will find the information in this report helpful. It will also be useful to elevators now providing grain drying services and wishing to increase their efficiency.
