ABSTRACT:
A process for cooling a hot concentrated product coming from an evaporator comprising evaporation means and a condenser, in relation with a vacuum source, which consists in providing expansion by stages at decreasing pressures during which the hot concentrated product is cooled by stages, a process which can be used in the case where the product before concentration is available at low temperature.
It is characterized in that with each expansion step there is associated a condenser where the vapor released at each corresponding expansion step is condensed, at least one of said condensers having passing therethrough a low temperature product, the product thus reheated being then fed to said evaporator for concentration.
