Working Principle of Yankee Dryer Cylinder
Steam enters the Yankee dryer cylinder and condenses on the internal surface of the shell, releasing heat through the cylinder wall. The heated cylinder surface then transfers heat to the paper web during continuous contact.
As moisture evaporates from the paper, the drying process reduces the water content of the web and helps maintain stable production conditions. Effective condensate removal is important for maintaining consistent heat transfer inside the cylinder.
A doctor blade can be used on the cylinder surface according to the machine configuration and production requirements.
