AI Technical Summary
Existing drying systems for flexographic and rotary printing or laminating machines using water-based or flammable solvent-based inks or glues face challenges in energy consumption and safety, particularly due to the risk of solvent vapor explosions at high temperatures, without effectively controlling solvent concentrations.
An automatic exhaust air recirculation system with integrated sensors and control units to monitor and regulate temperature and humidity, allowing partial recirculation of exhaust air, reducing energy consumption and preventing solvent condensation while maintaining product quality and safety.
The system achieves significant energy savings of 30-40% by optimizing air recirculation, reduces the risk of solvent condensation, and ensures safe operation by controlling solvent concentrations below hazardous levels, thereby enhancing the efficiency and safety of the drying process.
