Abstract
The baking or heat treating of products, which must take place at an extremely high temperature and under a strict non-oxidizing inert furnace atmosphere, is advantageously made by conveying the products into the furnace atmosphere only after having the products vacuum-packed in resinous films or bags, thereby to prevent oxygen, vapor, and the like, which might be trapped on or in the products, from entering into and contaminating the furnace atmosphere, and also in order to eliminate various apparatus which otherwise is required by conventional baking methods, such as vacuum chambers, bulky and thermal energy-wasting conveyor trays, and the like.
