A Device to Aid in Determining the Effectiveness of Dairy Detergents

Florida Agricultural Experiment Station, Gainesville, Florida

ABSTRACT

A wide variety of water types is found in Florida. Because of the widespread limestone deposits, waters of widely varying degrees of hardness are encountered. Also, because of the proximity of the Atlantic Ocean and the Gulf of Mexico considerable concentrations of salt. are found in the water in certain areas. A project is in progress to determine the most suitable washing powders to use with the various types of water. It is not the purpose of this paper to report the results of the experiments on washing powders but to describe the apparatus being used to aid in determining the effectiveness of various washing powders in cleaning dairy equipment.

The wide scope of this problem suggested the need for a mechanical device to aid in making washing trials. Since no such device was available, one was built. It has been named the Deterg-O-Meter. It consists of a 16-inch metal bicycle wheel mounted in a pivoted frame which permits vertical movement, powered by an electric motor and geared to turn at 7 r.p.m.
