Start-up team: Longjing Paper starts-up first Andritz-supplied PrimeLineHyTAD tissue machine

China’s Chongqing Longjing Paper Co. has started-up the first Andritz-supplied PrimeLineHyTAD tissue machine.

This start-up marks a milestone for premium tissue production in China, and also Andritz’s breakthrough with this technology in the industry.

Andritz said the PrimeLineHyTAD is specifically designed for fibre- and energy-saving production of premium tissue products such as kitchen towels, wiping paper, toilet paper, and facial tissues.

The company said: “With the unique HyTAD process, it can save up to 25% in fibre compared to traditional dry crepe tissue machines, and up to 50% in energy compared to structured TAD tissue machines.

“These savings significantly reduce production costs and meet current market demands for environmental protection and sustainability.”

Key components such as the PrimePress X shoe press and the PrimeDry IM impingement dryer play a major role in the HyTAD process.

The shoe press at Chongqing Longjing, with the largest diameter in the global tissue industry and a line load of up to 500 kN/m, achieves a dryness of approximately 48% after the press section. The impingement dryer utilizes exhaust air from the hood to pre-dry the paper, achieving more efficient drying while further reducing energy consumption.

The PrimeLineHyTAD tissue machine at Chongqing Longjing operates at a speed of up to 1,500mpm and has a width of 2.85m.

It is equipped with a Metris digitalisation system for data analysis, display, and statistical process control, further enhancing production efficiency and product quality.

Zhang Yun, President, Chongqing Longjing Paper Co., said: “This collaboration was a critical move in Longjing’s “Green + High-end” strategy.

“The Andritz team showcased professional execution, working closely with our team to realise start-up on schedule, securing the crucial timeline for mass production.

“This cooperation also serves as a benchmark and role model for in-depth collaboration between international equipment suppliers and Chinese enterprises.”

Prior to delivery, extensive testing was conducted at the Andritz Tissue Innovation and Application Centre to validate product quality and machine performance.

Chongqing Longjing Paper Co. was established in 2006 in Chongqing City.

The company produces household paper and products include toilet paper, facial tissues, boxed facial tissues, and other paper products, primarily using high-quality bamboo fibre as the raw material.
