AI Technical Summary
Existing developer dilution systems can only prepare a single concentration, resulting in low solution preparation efficiency and requiring long-term stirring, which cannot meet the needs of multiple concentrations under different process conditions.
It adopts a design with a developer inlet main pipe, a pure water inlet pipe and a mixed solution outlet pipe, and is equipped with independently controlled valves and flow and quality controllers. Combined with a spiral distributor, it can achieve efficient mixing and concentration adjustment.
This allows for the simultaneous preparation of diluents of the same concentration while increasing the dilution rate, reducing the need for stirring devices, and lowering costs.
