Process that involves the evaporation of liquids under an oxygen atmosphere. The exchange of oxygen with low humidity accelerates this process but may lead to an (unwanted) oxidation of the product. | |||
=== Nitrogen drying === | === Nitrogen drying === | ||
Process that involves the evaporation of liquids under an nitrogen atmosphere. The exchange of nitrogen accelerates this process. Since nitrogen is an inert gas unwanted reactions such as oxidation of the product are avoided. | |||

Process that involves the evaporation of liquids under different atmospheres. With increasing application of heat the process can be accelerated. Very high temperatures may lead to unwanted reactions of the product. | |||
=== Vacuum drying === | |||
Process that involves the evaporation of Liquids under an vacuum atmosphere. The vacuum atmosphere allows the evaporation of liquids at lower temperatures than under atmospheric pressure. | |||
