Abstract
An inspissate of a solution having a solvent which can be crystallized out by cooling is passed into contact with an internally cooled surface through which a coolant is circulated. Relative vibration is established between the solution to be cooled and the surface with at least the vibration of the surface being interrupted periodically or aperiodically. The solution and the surface can be vibrated separately in alternating periods.
