70 TPD Cultural Paper Machine for Paper Mill
The cultural paper machine is the core of any modern fine paper mill, combining high-speed operation with exceptional sheet quality. This cultural paper machine utilizes a fourdrinier section with a top wire former that allows improved formation and retention, resulting in optimal fiber distribution and bonding strength. The cultural paper machine’s press section employs a vacuum suction transfer roll followed by three hydraulically loaded nips and an additional straight press, achieving high dryness without crushing the sheet.
A key advantage of this cultural paper machine is the integration of vacuum cylinders in the pre-drying and post-drying sections, which enhance heat transfer and significantly reduce steam consumption. The cultural paper machine also includes a film transfer sizing machine with an air diverter, applying a precise amount of starch to both sides for improved surface strength and printability. A soft calender at the dry end ensures superior smoothness and gloss for high-quality printing applications. With a user-friendly design featuring hydraulic loading, electric tensioning devices, and a cordless tail threading system, this cultural paper machine minimizes downtime and maximizes output for mills producing food paper, wrapping paper, and other thin specialty grades.
