Riga 60:
* It is of course not applicable to compounds having ''reverse'' solubility, a term to indicate that solubiliti increases with temperature decrease (an example is sodium sulphate in the picture, where solubility is reverse above 32.5 °C).
The simplest cooling crystallizers are tanks provided with a [[mixer]] for internal circulation, where temperature decrease is obtained by heat exchange with an intermediate fluis circulatin in a jacket. These simple machines are used in batch processes, as in processing of [[pharmaceuticals]] and are prone to scaling. batch processes normally provide a relatively variable quality of product along the batch.
