Abstract
A source fluid from which solid material forms when it is cooled is passed through apparatus which defines a continuous reentrant lumen. The lumen has a thermally conductive processing wall from which heat is extracted from the outside as the source fluid flows through the lumen, resulting in formation of solid material on the inner surface of the lumen wall. A runner circulates around the lumen and dislodges material deposited on the inner surface of the lumen wall. This material is then carried as solids of a slurry out of the apparatus with the fluid stream.
