ANDRITZ SEPARATION GmbH Hall 8 / F42

With ANDRITZ’s innovative solutions you can unlock the full potential of carded filter production. Our technologies are engineered to ensure web regularity and productivity, setting new industry standards in the field of inline carded filters. Opt for a single TT card to cut costs and achieve higher weights, boosting throughput at the end of line drastically.

In addition, the ANDRITZ portfolio offers outstanding patented solutions to achieve unprecedented uniformity in crosslapped processes:

• The ProWin™ system sets a new benchmark for web weight regularity, ensuring consistent quality across your products.
• The Battcruise system integration allows further enhancement of the fabric quality by minimizing unnecessary draft at the crosslapper exit, thus providing precise control over evenness.
• The DF-4 Elliptica mode for producing needlepunched lightweight materials (<70gsm) at high-speed (30m/min) without compromising on product regularity & visual aspect quality.

With ANDRITZ’s technologies, you are not just investing in machinery. You are investing in a future of unparalleled quality and efficiency in nonwoven fabric production for filters, allowing you to benefit from key competitive advantages on the market.

Cross-flow technology for separating substances with poor filtration properties are state of the art technology for solid-liquid separation in chemical and pharmaceutical industry. With traditional cross-flow filtration the development of the clogging layer at the surface of the filter membranes is prevented by re-circulating the feed. When handling sensitive or highly viscous products, this method is not efficient or even not applicable. With Andritz Dynamic Cross Flow filtration (DCF) recirculation can be avoided and processing of high viscous products with pasty consistency is possible.

In DCF shear forces are generated between the overlapping rotating disks. By this effect, the crossflow is generated without pumping and circulating the slurry, but just by the rotation of the membranes themselves...

For most of the players in food and chemical industries, using a DCF is an efficient way to filtrate different products but today, operations need significant improvement to gain in productivity and reduce opex. Up to now, the huge potential of Dynamic Crossflow Filter technology in industrial processes is often not utilized, because quick reaction time of the system to varying process conditions are not possible by fixed recipes. In order to further increase long-term performance of DCF and allow the handling of varying process conditions a digital twin was developed for an industrial DCF plant. The digital replica of the physical process uses asset-specific information such as actual physical dimensions and equipment characteristics and runs in parallel with operations, continuously calculating key process parameters which sometimes cannot be measured or are difficult to measure by traditional instrumentation. Through proven simulation capabilities, combined with live plant data as an input, it calculates continuously the optimal flow setpoint, and performs what-if scenario analysis.

During the harvesting season in 2022 and 2023 in total 24 industrial production batches of grape juice were analyzed in this project. After implementation of the digital twin the...
