Oslo crystallizer

Oslo crystallizer has a structure that the evaporation chamber is separated from crystallization tank. The mother liquor which is clarified at top clarification gone of crystallization tank extracted from the small crystallization zone is concentrated by evaporating in evaporation chamber after passing heat exchanger.
A supersaturated liquid concentrated in evaporation chamber go down through tail pipe then is supplied to bottom of crystallization tank. The liquid penetrate fluidized crystal bed and crystals grow by contacting and desupersaturation of liquid.

No mechanical crystal breakup
The circulation pump transfers clear liquid only, producing no mechanical crystal breakup.
