After being developed and washed clean of the fixing solution, the film is removed from the wooden racks and wrapped around a wooden drum suspended from the ceiling of the drying chamber. The temperature, humidity, and ventilation of the chamber must be uniform and consistent for the duration to inhibit devastating curling, buckling, or other distortions. Automatically conditioned air is delivered at a reasonably high velocity through a row of patented ejector nozzles located near the ceiling for faster drying. Additionally, the air circulating through must be filtered and cleaned before entering the space to avert any dust or particles from settling on the films’ moist surfaces. Alternatively, Duplex cabinet drying machines are equipped with fans, heaters, and temperature and humidity control instruments to dry at a rate of 30 feet per minute.
