The SteamDry project is pioneering the future of sustainable web material drying in the paper and pulp industry through the implementation of superheated steam drying (SSD). At the heart of this transformation lies a robust and forward-looking IT concept—designed to support simulation, monitoring, optimization, and control of the entire drying process.
Smarter Models for a Greener Industry
SteamDry’s IT concept outlines a comprehensive suite of models, from static and dynamic simulations to advanced drying physics and fouling detection. These models form the foundation for digital twins that replicate real-time operations of dryers, heat exchangers, steam cleaners, and more. The digital twins will enable near real-time optimization, predictive analytics, and anomaly detection.
A Future-Ready Data Infrastructure
A dedicated data platform complements the existing automation systems at VTT’s pilot plant. This platform is equipped to store time-series and asset data, leveraging PostgreSQL with TimescaleDB for high-efficiency logging and retrieval. Modular APIs built on modern protocols like HTTP and MQTT allow seamless integration of sensor data, model outputs, and control recommendations.
From Recommendations to Real-Time Control
SteamDry’s agent-based control algorithms focus on multi-objective optimization—balancing energy consumption, product moisture content, and overall process efficiency. Initially, operators will manually implement suggested setpoints. As the system matures, direct control interfaces may enable autonomous adjustments, closing the loop between digital insights and physical action.
Built on Open Standards, Geared for Flexibility
The IT architecture prioritizes flexibility and interoperability. The use of open-source technologies like Grafana for visualization, Keycloak for identity management, and Docker/Kubernetes for deployment ensures a scalable and adaptable system. APIs follow the OpenAPI and AsyncAPI standards, encouraging collaboration and future expansion.
Digital Twins Driving Sustainability
This IT concept is more than a technical framework—it’s a critical enabler for environmental and economic impact. By coupling digital models with live data and intelligent controls, SteamDry aims to cut energy use, reduce emissions, and support the transition to a circular and decarbonized industry.
What’s Next
As the project advances, the IT concept will evolve. Integration of coupled simulations, advanced user interfaces, and new control strategies are expected to enhance the digital ecosystem. SteamDry continues to push the boundaries of what’s possible in industrial drying through innovation grounded in solid digital infrastructure.
