  • Process for the separation of substances by cooling crystallization
    Patent number: 5090965
    Abstract: In the process for the separation of substances by cooling crystallization, the mixture remaining in the crystallizer after separation of the crystal layer is removed and the crystal layer is melted. The process is distinguished in that the mixture, which completely fills the crystallizer, is set into vibration during the process of solidification by movements of oscillation imparted to it and is left in the crystallizer until a degree of solidification of from 50% to 90% has been obtained.
