With the CleanLine Extract360, leading full-line supplier Voith is launching a new, highly effective fabric cleaning system for the dryer section of paper machines. The innovative system is designed to overcome limitations of conventional dryer fabric cleaning, enabling excellent cleaning results, reliably removing wastewater, and extending fabric life by reducing cleaning pressure. By keeping the fabric, the cleaning system itself and the entire machine environment cleaner, the technology makes a significant contribution to the runability of the system and reduces the risk of paper defects.
The increasing processing of recycled fibers in paper production leads to higher contamination of the fabrics, rolls and equipment in the dryer section, thereby adversely affecting machine efficiency and paper quality. For optimum cleaning results and maximum machine performance, Voith's proven Extract cleaning concept is based on a combination of two principles: First, multidirectional cleaning removes contamination both on the surface and in the structure of the fabric. Second, the positioning of the cleaning head after the roll enables additional dirt removal on the nonpaper side of the fabric.
“The newly developed Extract360 cleaning head builds on the marketproven principles of CleanLine Extract4D and provides even more ways to reduce the negative effects of contamination in the dryer section”, says Nick Lampart, Product Manager at Voith Paper.
- Edges and joints of conventional cleaning heads facilitate the accumulation of contamination during production. The generative design of the Extract360 cleaning head minimizes these interference points, avoiding self-contamination and ensuring consistently high cleaning performance.
- The flow-optimized vacuum channel of CleanLine Extract360 is merged directly with the cleaning zone, enabling improved removal of wastewater and ensuring maximum functionality and reliability
- With flow-optimized high-pressure channels, the jet quality of the cleaning nozzles is significantly improved. Based on specific customer requirements, this enhancement can either increase the cleaning effect at the same pressure level or achieve an equivalent result at even lower pressures, reducing strain on the fabric.
The technology is already in use in several paper mills where operators have observed significant improvements in fabric cleaning and confirmed efficiency gains following the system's installation.
Voith's CleanLine portfolio includes cleaning solutions for the forming, press, dryer and coating sections of the paper machine. Continuous development of these systems is aimed at achieving the best cleaning performance combined with high ease of maintenance and machine availability.
