Abstract

Automatic control was first implemented some 60 years ago in the form of complex pneumatic mechanical gadgets, paving the way for a new and revolutionary method for producing the basic commodities of that time. The pasteurization process is one of the first application areas of automatic control (Babb, 1990). The process is simple — the temperature of a batch of milk is raised to 143 deg F and held there for 30 minutes to complete pasteurization. Around 1912, the dairy industry began logging and keeping records of the pasteurization process, due probably to the American government having more direct control over pasteurization. This was good news for thermometer manufacturer Taylor Instruments, based in Rochester, N.Y., which has not been doing too well with the sales of the mercury thermometers.
