Excerpts from the report: This research was conducted cooperatively by the Purdue University Agricultural Experiment Station and the U.S. Department of Agriculture. The data on work methods and equipment were obtained from studies of ice cream manufacturing operations throughout Indiana. The purpose of the research was to provide ice cream plant operators with data and guidelines which could be used in establishing and operating ice cream plants more efficiently. The objectives were to (1) measure the relative efficiencies of various work methods and various types and combinations of types of equipment used in ice cream plants; (2) compare the various combinations of work methods and equipment to determine their effects on the economy of plant operations; and (3) develop plant layouts showing arrangement of equipment and flow of materials.
