Longjing Paper, China, starts up first ANDRITZ PrimeLineHyTAD tissue machine

Chongqing Longjing Paper Co., Ltd. has successfully started up the first ANDRITZ PrimeLineHyTAD tissue machine. This start-up not only marks a milestone for premium tissue production in China but also ANDRITZ’s breakthrough with this technology in the industry.

The PrimeLineHyTAD is specifically designed for fiber- and energy-saving production of premium tissue products such as kitchen towels, wiping paper, toilet paper, and facial tissues. With the unique HyTAD process, it can save up to 25% in fiber 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 1,500 meters per minute and has a width of 2.85 meters. It is equipped with a Metris digitalization system for data analysis, display, and statistical process control, further enhancing production efficiency and product quality. ANDRITZ also provided comprehensive services covering installation supervision, commissioning, start-up, and training, ensuring the smooth start-up of the equipment.

Prior to delivery, extensive testing was conducted at the ANDRITZ Tissue Innovation and Application Center to validate product quality and machine performance. As the world’s most advanced pilot plant for tissue, the center is open to customers and research institutes for the development and testing of innovative tissue solutions.

Chongqing Longjing Paper Co., Ltd. was established in 2006 in Chongqing City. The company focuses on the production and manufacturing of household paper. Its main products include toilet paper, facial tissues, boxed facial tissues, and other paper products, primarily using high-quality bamboo fiber as the raw material.
