Description of the Vacuum Pan. —The \acuum pan is a retort in which the milk is heated and evapo- rated in partial \'acuum. The origin of the term "pan" has not been satisfactorily ex]ilained. Tn the early and experimental days of the manu- facture of condensed milk, the milk was e\'aporated in open kettles, called pans. It is probable that the name of this primitive apparatus \\-as passed on to the more perfected machinery now* in use. The \'acuum pans are construct- ed of copper, iron, steel or bronze r^racticalK' all of the \-acuum pans used for condensing milk are made of cop[)cr througlKTUt; the^• are of \ari(ius styles and sizes. The pre- dominating size used in milk con- denseries is the "six-foot ; By the term six-foot is meant a retort measuring six feet in diameter. There are two general t\]>es nf \ .icuuin pans on the market; pans that .are relati\el\' wide in ili:imeter and shallow in depth, and [jans oi relatixely naii-ow diameter and which ha\'e a deep l)od\', I'poth t\'pes ;ire claimed, b\' their respectix'e manufacturers, to ha\e special ad\ antages, such as ease of o|)eration, uniformit\' ijf actiiiu, econoni)- of fuel aurl of water, and rapidit\' of ex'apora-.
