ABSTRACT:
An apparatus for performing centrifugal crystallization of organics, which unifies all the individual steps for the removal of impurities into a single operation. The apparatus consists of two coaxial rotors and stationary parts. A crystallizable feed stock is mixed under pressure with a suitable refrigerating solvent and injected into a rotating liquid ring of the process materials. A faster drum-shaped outer rotor rotates the process materials while a slower frame-shaped inner rotor distributes the combined feed, collects refined product and recycles crystal fines as seeds. Advantage is taken of the centrifugal force and of the radial pressure gradient for gradual adiabatic evaporation of the solvent and simultaneous crystallization of the substance to be purified, as well as for the separation of phases, counter-current crystal washing with its own melt, followed by product melting by external heat, and withdrawal of a product from the apparatus. The refrigerant solvent vapor is recycled after liquefaction.
