A Review of the Drying of Silver Halide Photographic Film

With the advent of hardened emulsions, high-temperature processing and processing solutions with high electrochemical energy, the “wet” processing of silver halide photographic film has reached a plateau where the rate of processing is fast becoming “drier limited,” particularly for wide film. The drier itself may now exceed in size the rest of the machine, and consume the major portion of the total electrical energy required, in addition to increasing the power and equipment rating of the environmental air-conditioning system. A summary of the drying process is made together with a review and comparison of technologies by which a drying rate in excess of 100 ft/min can be obtained with higher overall efficiency, and with compactness of mechanical design. The results of studies conducted by the authors are included.
