  • Process and apparatus for the crystallization of a melt
    Patent number: 5445108
    Abstract: A melt is crystallized by introducing the melt into a gap formed between two belts. The gap-forming flights of the belts travel in opposite directions. An upper one of the flights is cooled so that an upper surface of the melt crystallizes thereon and is removed from the gap on the upper belt. The lower belt removes the residual melt from the gap and that residual melt is recycled to the gap.
    Type: Grant
    Filed: September 10, 1993
    Date of Patent: August 29, 1995
    Assignee: Santrade Ltd.
    Inventors: Konrad Schermutzki, Herbert Wurmseher

  • Process and apparatus for the purification of substances
    Patent number: 5149445
    Abstract: A substance is provided in molten form and then converted into crystallized pellets. The pellets are conveyed into a vessel having an open lower end, whereby the pellets continuously advance downwardly. As the pellets advance, they are subjected to a hot gas flow which causes outer contaminated surfaces of the pellets to melt and drip off. The remaining pellets travel out through the opening in a direction transversely of the direction of the dripping. In this manner, the substance is purified.
