The image you see provides a summary view of the sublimation method. In this process, raw iodine slurry is first heated in evaporators until it melts and iodine vapors are produced. These vapors are directly directed to a condenser, which is cooled by a flow of cold air. When the iodine vapors come into contact with the cold walls of the condenser, they deposit as iodine crystals on the walls. The crystals are then separated and collected as high-purity sublimated iodine.
