    Abstract: In the working up of organic materials which are normally crystalline, where the materials, as powder or liq. melt, are processed in a 2-shaft screw machine with the worm shafts rotating in the same direction, are expelled through a narrowed passage into a zone at low pressure, and are cooled and comminuted, the materials are heated to form a melt film during transit through the narrowed passage.
