Drying Technology

Gentle drying under vacuum

Among the thermal processes, vacuum drying has proven particularly effective in many sectors. The purpose of this process is to gently dry a high-grade product containing water or solvents without modifying the product characteristics.

During drying under vacuum, the total pressure in the drying oven is lowered so that the water or solvent vaporizes even at low temperatures.

The drying process is optimized by selectively controlling the heat supply and pressure.

A vacuum drying system consists basically of a drying oven with a heating system and a vacuum pump assembly designed for a specific drying process with the associated control.
