Selection of a suitable drying method
What is drying?
In cleaning technology, drying means the removal without residues of water residues adhering after the cleaning process.
Component and cleanliness-related factors affecting drying
- Component geometry
- Cleanliness-/quality requirement
Conventional drying methods
- Blowing off or if need be a "Suction" as well with simple geometries
- Warm/hot air drying systems (recirculating/feed air dryer)
- Indirect/"contactless" thermal drying e.g. by means of an IR radiator
- Vacuum drying
- Condensation drying
At the boundaries of water-based cleaning systems, the use of conventional systems functions only to a limited degree. Even when drying bulk goods, with capillary structures (e.g. blind holes, clearance holes with diameter less than 1 mm) or with special materials (such as sintered metals), new methods or combinations are required:
- CNp drying
- Use of superheated steam
