Drying Device Partition Plate for Uniform Film Solvent Volatilization

The drying chamber is segmented into multiple zones with different exhaust capacities. The partition plate divides the chamber into a first drying chamber (with smaller exhaust capacity) and a second drying chamber (with larger exhaust capacity), allowing different regions to have optimized drying conditions for their specific needs.

Different regions of the drying chamber are given different exhaust capacities matched to their local drying requirements. The partition plate with selectively positioned and sized exhaust ports creates local variations in exhaust capacity, ensuring each area has the appropriate drying strength for its position relative to the substrate.

The exhaust system is segmented into multiple exhaust ports distributed across the partition plate rather than concentrated at a single corner location. This segmentation of the exhaust function creates more uniform airflow distribution throughout the drying chamber.

The partition plate acts as an intermediary structure that mediates between the substrate and the exhaust mechanism. It distributes the exhaust function across multiple locations and uses the holes of different sizes to regulate airflow, creating uniform solvent volatilization rates across different areas.

The partition plate is designed with non-uniform hole distribution where the density and/or size of holes vary in different regions. Specifically, edge areas have holes with larger total cross-sectional area or higher density to compensate for their naturally higher volatilization rates, while central areas have smaller or sparser holes.

The parameters of the exhaust ports (hole size, hole density, cross-sectional area) are changed across different regions of the partition plate. This spatial variation in exhaust port parameters allows the system to compensate for position-dependent volatilization rate differences and achieve uniform drying across the entire substrate surface.
