摘要

The method involves guiding through gas by cavity which is to be dried and using gas which is colder relative to ambient temperature in initial state. Colder gas is mixed with drying air. The gas which is used, is in such a manner cold in the initial state that it is in the firm, liquid or gaseous phase. Gas is liquid air or liquid nitrogen.
