Drying (evaporation)

All drying technologies are based on the evaporation of different liquids under different gas atmospheres and physical conditions resulting in dry products or products with a desired humidity.

Air drying

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

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.

Freeze drying

Also known as lyophilisation. The technology represents a low temperature dehydration process that involves freezing the product, lowering pressure, then removing the ice by sublimation.

Thermal drying

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.
