Cartigliano introduces freeze-drying for hides
02/03/2015
Benefits include lower energy consumption than previous models but a higher drying capacity. In addition, a-CNS requires less space on the tannery floor.
Most attention at the event, however, was on Cartigliano’s claim that, because a-CNS can dry hides at a lower temperature, the new model introduces “freeze-drying” to the tanning industry.
Drying hides at a lower temperature will help tanners preserve the natural qualities of hides in their finished leather, Cartigliano said at Tanning Tech. It also said the process with a-CNS requires less fat liquoring and that shrinkage is reduced.
You can dry hides “more deeply”, the company said, fixing the fibres. It added that a major global tanning group has already invested heavily in this system and that it has experienced an average increase in hide yield of 4% without any compromise on quality.
