Chongqing Longjing Paper Co., Ltd. Successfully Starts up 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 fibre- 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 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 500kN/m, achieves a dryness of approximately 48% after the press section. The impingement dryer utilises 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 metres per minute and has a width of 2.85 metres. It is equipped with a Metris digitalisation 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.

From technical proposal to paper on reel, the ANDRITZ team demonstrated exceptional professionalism. 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.

We will keep innovating together with customers and continuously deliver low-carbon solutions for China and the global market.”

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