and giving less opportunity for errors.
Additionally, the new felt changing system that is part of EvoDry is quick and easy to install and remove, thus providing another improvement to increase runnability and safety.
Environmental and energy efficiency A significant factor in the design of EvoDry is the creation of a pulp drying system that helps to improve the environmental impact of various mill processes. This has been achieved by optimising newly-designed key equipment to reduce energy consumption and introducing new developments in energy- saving technologies, such as the boiler exhaust energy recovery
system or the newly designed combi-press. In addition to energy use, another environmental concern for pulp drying lines is the need for large quantities of fresh water. This important issue has received much consideration in the design of the EvoDry system. The new pulp drying system can reduce the consumption of fresh water by reusing more of the internal process water. This brings a reduction in operating costs the mill’s impact on the environment. In creating a new, efficient, and
reliable pulp drying line that is more environmentally-friendly, has improved health and safety features, is low maintenance, and has higher operational runnability, Andtritz has also
designed a system that has lower operating costs. The more efficient equipment, the lower energy requirements, and the ability to reuse water from other stages of the process all combine to reduce the overall expenses of running a drying line.
Industrial IoT solution The EvoDry pulp drying system is an efficient and reliable drying line, and offers greater reliability and more flexibility than any previous drying systems. The introduction of a web-based solution called PRECIT (through the use of Metris – the Andritz brand of Industrial Internet of Things) enables performance monitoring, data analysis, fault detection, and maintenance efficiency, and makes EvoDry one
of the most innovative all-in-one drying systems available. With the EvoDry pulp drying
system, Andritz has optimised pulp drying performance by introducing key factors such as:
● Higher operational runnability ● Improved performance and reliability
● High-quality pulp ● Reduced operating costs ● Increased health and safety performance
● Improved environmental conditions
● Minimised downtime ● Industrial IoT solution ● Environmental and energy efficiency
● Health and safety concepts ● Highest operational reliability
