Period

Specific:This unit used in late 1990s.

Canada

Distributed and used in Canada and among the most popular home pasteurizers on the North American market.

Function

Performs batch processing of small quantities of raw milk, in order to slow spoilage.

Technical

This home pasteurizer is based upon the double boiler method, proven early in the 20th century to be the most effective and efficient method of batch pasteurization of raw milk. As early as the 1930s, research had shown that heating milk at the relatively low temperatures of 140 F to 145 F was effective in the elimination of harmful bacteria and milk-borne diseases when that temperature was maintained for 30 minutes. The equipment necessary to perform such an operation lagged behind the science, however, as Robert C. Thomas describes in his 1949 study of home pasteurizers. Three principle problems affected the use of these early appliances: 1) the temperature was not well controlled; 2) precipitation of milk solids still occurred; and 3) the milk had a slightly cooked flavour. Thomas’ study suggested that in order to improve this method, “more refinements in equipment construction and more accurate controls [were] needed to ensure that all milk is held for the correct time at the proper temperature.” SafGard Division of The Schlueter Company began manufacturing home pasteurizers in the late 1950s, likely in response to the increasing demand from their farmer clientele as pasteurized milk became more commonplace. Over the course of its production, SafGard has perfected the technology required for batch pasteurization in a safe and efficient counter-top appliance and is among the most popular home pasteurizers on the market. It is advertised as “the only home pasteurizer” with automatic operation with a thermostat to maintain constant temperatures of between 155 F to 159 F, automatic shutoff when pasteurization is complete, and a buzzer that notifies the user when the milk is ready for cooling.
