OraFlex™ guarantees uniform pressure distribution along
the roll’s surface without the need for profiling, a great pneumatic
oscillating capability to enhance cleaning efficiency.
A more modern pneumatic oscillation system (developed by
Oradoc) was designed to replace the outdated electromechanical
one, in order to provide consistent and controlled oscillation to the
doctor blade, ensuring effective cleaning and residue removal. This
new solution ultimately resulted in reduced wear on components and
improved overall system performance.
Main benefits include improved cleaning performance and
enhanced paper quality.
OraDust™ is the latest Oradoc’s product: a dust removal
system integrated onto the doctor beam, connected to a customdesigned suction system. It effectively removes paper dust and
residues from the doctor blade’s surface, preventing contamination
during the drying process, thus enhancing cleaning efficiency,
improving product quality and minimizing maintenance needs.
The system is composed of a dedicated suction box made
of stainless steel connected (through a special high-temperature
resistant tube) to a suction mouth along the entire length of the
blade.
The sizing and design allow for an optimal setup both in
positioning (distance between the suction slit and the bevel of the
blade) and ergonomics, minimizing total space, thus avoiding issues
during normal production.
OraDust is connected to a dedicated suction system (in this
specific case) composed of piping, filtration, and a dedicated fan.
The sizing has been conceived in accordance with the customer,
allowing for it to be used also for the installation of two additional
OraDust units on subsequent dryers.
Suction control can be adjusted through DCS, in order to
increase or decrease the suction flow, thus improving efficiency.
The installation, set-up and commissioning of the new
systems were carried out under the supervision of Oradoc’s
technical team, ensuring seamless integration and optimal
performance.
A short breakdown of goals achieved
• enhanced paper quality: better cleaning mechanisms
led to higher-quality paper with fewer defects.
• increased operational ef昀椀ciency: modernized systems
reduced downtime and maintenance requirements,
improving the overall drying process
• cost savings: by reducing waste and improving
operational efficiency, the customer achieved a
reduction in operational costs
• sustainability: enhanced cleaning and efficiency
measures supported more sustainable production
practices.
Oradoc’s tailored solutions addressed the customer’s
specific challenges and long-standing issues of paper
contamination, leading to significant improvements in product quality
and operational efficiency. The integration of advanced technologies
demonstrated Oradoc’s commitment to innovation and excellence in
the paper industry.
