Yankee Hoods and Air Systems (Hottes et circuits d’air de sécheur Yankee​)

Together, the Yankee dryer and Yankee hoods provide the final drying of a tissue sheet before it is wound up by the reel. Some of the drying energy is provided by steam condensing inside the dryer, and the rest is provided by hot air being blown onto the sheet by the Yankee hoods. This module describes the equipment and processes responsible for supplying dry, heated air to, and removing humid exhaust air, from the Yankee hoods on a typical, modern Yankee dryer.
