A method for cooling processed food materials has a steam generator for a cooling solution and vapor injection system into an evacuated chamber

摘要

The chamber (1) containing the food items is evacuated by a pump (14) and a reservoir containing a solution of, for example, 50 per cent lithium bromide is heated (7) to produce vapor which is injected (3) into a vessel (4) within the chamber by a pump (11) through a cooler (12).
