Zaronchentsev had developed a technique of placing all of the products to be frozen on mesh metal shelving which would then be sprayed with a calcium chloride brine solution as a mist, which speeded the freezing process. This method was entirely different from the flash freezing methods developed by Clarence Birdseye, whose innovations involved holding packaged food between two metal belts chilled to -45 degrees Fahrenheit, or under pressure between two hollow metal plates chilled to -25 degrees Fahrenheit through evaporation of ammonia, freezing items from 30-90 minutes. Zaronchentsev (b. 1879) who had pioneered refrigeration engineering while studying at the Institute of Transportation in Moscow prior to the Russian Revolution, later oversaw the construction of numerous packaging houses, cold storage facilities, and thousands of refrigerated railwar cars. From 1922 to 1927 he had become the general manager of the Estonion packing house A/S Kulmetus, with many of th ephotos here showing his work in Estonia, and across Europe during the period. In 1928, he contracted with the British firm H. Smethurst \u0026 Co. in Grimsby which used his technology to freeze, package and market frozen salmon rolls, fish ovals, fish cakes, and others, shown here in the photos, but three years later decided he would have to move to the U.S. for financing and build the company.","\"In New York, he contracted initially with the Francis Metal Door \u0026 Window Corp. in Rochester, NY to build his specialty freezers, and equipment, and incorporated as the American Z Corporation, with branches in Brooklyn, NY and other locales. He also began setting up test farms to grow vegetables, fruits, and poultry, especially duck, to develop a whole line of locally sourced frozen goods using his equipment. The carefully annotated photographs show the many different products frozen and being frozen including green peas, frozen shrimp in pans and cartons, pork chops, ham and pork bellies, pork brains in cartons, lamb chops, duck, fish fillets, and sausages, including those in cellophane display cartons. The patented 'brine-fog-' method together with applied pure cane sugar prevented fruit from losing their colour, as well as preserving aroma, nutrients, and essential vitamins. By 1938, the Japanese firm Nippon Suisan had tested the devices, and methods of cold storage facilities and production facilities in Misaki, Nemuro, and Takao (Taiwan), focused primarily on farm shrimp marketed as Horai Shrimp in Japan, and frozen swordfish exported across the Pacific.\"","The copyright status of this collection is unknown.
