A Yankee dryer is a pressure vessel used in the production of tissue paper. On the Yankee dryer, the paper goes from approximately 42–45% dryness to just over 89% dryness. In industry, MG cylinders or Yankee dryers are primarily used to remove excess moisture from pulp that is about to be converted into paper. The Yankee cylinder can be equipped with a doctor blade and sprayed with adhesives to make the paper stick. Creping is done by the Yankee's doctor blade that is scraping the dry paper off the cylinder surface thereby crêping the paper. The crinkle (crêping) is controlled by the strength of the adhesive, geometry of the doctor blade, speed difference between the yankee and final section of the paper machine and paper pulp characteristics.
Famous quotes containing the word yankee:
“The other 1000 are principally the ‘old Yankee stock,’ who have lost the town, politically, to the Portuguese; who deplore the influx of the ‘off-Cape furriners’; and to whom a volume of genealogy is a piece of escape literature.”
