Abstract
A syrup of mannitol and of sorbitol is introduced through a pipe (2) into a first crystallization zone (1a) which it is led to pass through with stirring (3) and within which the temperature is maintained substantially constant by a system (4), the mixture of syrup and of crystals of mannitol being led through a pipe (8) to a second crystallization zone (1b) which it is led to pass through and within which it is subjected to a temperature gradient decreasing globally possibly modulated by a system of temperature regulation (12), the mixture emerging from this second zone being in the form of a crystalline mass rich in mannitol crystals from which the latter are recovered. A system of recycling (13) leads, in the vicinity of the upper end of the container (1a), a part of the contents of the container (1b) taken up to a level (15).
