Yankee Dryer Cylinder
Cast iron or steel Yankee cylinders engineered for efficient drying and creping operations.
Cast iron or steel Yankee cylinders engineered for efficient drying and creping operations.
The Yankee dryer cylinder is the defining component of the tissue machine, performing the critical functions of drying, sheet support during creping, and surface finishing. Parason's Yankee cylinders represent the culmination of our metallurgical expertise and thermal engineering knowledge accumulated over 50 years of paper machinery manufacturing.
Our Yankee cylinders are manufactured to exacting standards that ensure uniform shell thickness, precise surface geometry, and optimal thermal characteristics. The cylinder shell—available in both cast iron and fabricated steel constructions—withstands mechanical and thermal stresses of high-speed tissue production.
The internal condensate removal system is engineered for maximum thermal efficiency, ensuring that steam energy is transferred to the sheet. This attention to thermal design delivers the 3-5% steam savings that distinguish Parason Yankee cylinders.
