The Role of Dryer Cylinders in Papermaking Process

Dryer cylinders are core components in papermaking, primarily responsible for dewatering and drying wet paper webs to meet production quality and efficiency requirements. Crafted from high-quality steel with smooth surfaces, they work with press sections and drying hoods to realize continuous papermaking.

After the press section removes most water, wet paper webs enter the dryer section and wrap around rotating dryer cylinders. Heated internally by steam, the cylinders transfer heat to the paper web, evaporating residual moisture (reducing water content to 5-8%). Their smooth surface also enhances paper’s flatness and gloss.

Beyond drying, dryer cylinders regulate paper’s moisture uniformity—critical for preventing brittleness or deformation. They boost production efficiency by enabling high-speed continuous drying, matching modern papermaking lines’ pace. Additionally, paired with doctor blades, they keep surfaces clean, avoiding paper defects from debris buildup.

In summary, dryer cylinders directly impact paper quality (moisture, flatness) and production efficiency, being indispensable in the papermaking process.
