The Condebelt drying process was patented in 1975. The Condebelt drying process was originally created to increase drying rates of paper. Condebelt drying produces approximately 10-15 times higher drying rates than conventional cylinder drying. These higher drying rates are achieved by higher contact temperatures, higher pressing between the hot surface and paper and relatively low thermal resistance between steam and paper in the Condebelt drying process.
According to Retulainen (2001), three features of the technology warranted further investigation after the first pilot tests:
