I have a drying cabinet and with the heat on, itʻs generally about 10 minutes. But if I am not in a rush, it is better to let it naturally dry. The relative humidity will determine how quickly it will dry, but usually anywhere from 4-8 hours. The general rule of thumb (no pun intended) is with dry and clean thumb and index fingers, touch the head/tail top/bottom of the film where there are no exposures. If it is smooth to the touch, itʻs dry. If it is at all tacky/sticky, itʻs not dry yet.
C-41 film processors can dry film at high heat and filtered air circulation in less than a minute, but it is precision timed by a microprocessor and I wouldnʻt try anything like that manually.
