VEPL Semi Automatic Standred Cooling Type Crystallizer

In most solutions, the solubility of the compound increases with rising temperature.  As saturated solutions cool, the mixture becomes supersaturated and crystallization starts.  The major advantages of cooling crystallization are very high uniformity of crystal size and energy efficiency.  With heat input for evaporation eliminated, a tremendous energy savings is established.  A common method of cooling crystallization is flash cooling, in which a part of the liquid is evaporated, thus removing the latent heat and allowing for cooling.  Warm feed solution is circulated and cooled over time by progressively reducing the pressure in either a batch or continuous fashion.  This may also be employed in combination with an evaporation system.
