the USA to Europe. In 1925 American inventor and industrialist Clarence Birdseye came up with a method of freezing that did not rob food of its flavor. His method, called quick freezing operated on the premise that the faster the freezing, the less danger there was that ice crystals would rupture the cell walls of the food item. Some of the foods that Clarence Birdseye subjected to quick freezing were peas, spinach, rasberries, cherries, fish and meat. The development of refrigeration systems was greatly assisted by the introduction of reliable electric motors and public electricity supplies and the first domestic machines came on the market shortly after World War I, deep freeze units for home use being introduced in the mid 1930’s. The first refrigerator, as opposed to the simple ice box, designed for home use was the Domelre, which was manufactured in Chicago in 1913. A number of other competing machines quickly appeared, but in 1918 Kelvinator marketed a much more practical home refrigerator. Frigidaire followed with their model in 1919. In 1927, General Electric introduced a refrigerator with a “monitor top” containing a hermetically sealed compressor. U.S. electric refrigerator sales top 800,000 and the average price of a refrigerator falls to $292 in 1929. The first built-in refrigerator was launched by Electrolux in 1930. A compact product for the kitchenette in the small, modern apartments of the time. The next year they produced the first air-cooled refrigerator. The familiar dual temperature refrigerator is in use today, with one section for frozen food and a second for chilled food, was introduced into mass production by General Electric in 1939.During the 1940s frozen food storage became widely used by consumers. Refrigeration technology began hopping in the 1950s and ‘60s when innovations like automatic defrost and automatic ice makers first appeared. Life changed immensely in the 20t...
