A Study of a Cream Separator Bowl Which is Cleaned by Centrifugal Flushing

Abstract

Tracy and Tuckey (8) in 1938 conducted a number of experiments with the English machine. The purpose of these early experiments was to study the automatic cleaning principle of this separator and ascertain its practical usefulness under farm conditions. The machine was used on two different farms near the Illinois Agricultural Experiment Station for periods of 5 to 7 days. Its operation also was studied in the dairy laboratories of the Experiment Station and results compared with those of a well-known American separator. The bacterial quality of the cream and skim milk was determined.. The results of 24 separations, involving 12 comparisons, indicated that the English machine compared favorably with the American machine when both were operated under comparable conditions. This preliminary investigation indicated that the English separator was cleaned easily, that it was practical, that dairymen were interested in its development, and that the two farmers who used the separator were pleased with its performance. The separator was returned to England and World War II delayed further developments.
