|description===Production process==

*The coated daughter rolls are pushed onto a special goods carrier.
*The coils are then stored in a vacuum oven.
*The drying time is approx. 12 h to 30 h. During the drying process, residual moisture and solvents are removed from the coils.
*The reduction of residual moisture is achieved by evaporation at low temperatures as a result of a low total pressure.
*After vacuum drying has been completed, the coils are transferred directly to the dry room or dry packed under vacuum.
*The vacuum ovens are often used as air locks into the dry room (for daughter rolls).
*In addition, it is possible to operate the vacuum ovens with inert gas in order to prevent corrosion.

==Process parameters & requirements==

*Working pressure: 0.07 mbar < p < 1000 mbar
*Drying time: 12 h - 30 h per batch
*Drying temperature: 60°C - 150°C
*Inert gas supply

==Technology alternatives==

*Continuous dryers: In contrast to the chamber concept, there are also continuous drying processes in which the daughter rolls are transported through a long drying facility in a wound or unwound state.
*Infrared dryer: Both technologies can be supplemented by infrared heating.

==Quality influences==

*Constant heat supply and stable vacuum
*Longer resting times only possible in the dry room
*Inert gas supply against corrosion

==Quality features==

*Surface condition (cracks, etc.)
*Residual moisture content (no residual moisture desired)
