Sugar BioEnergy vertical crystalliser-FIVES Fives Sugar-Bioenergy

In the modern sugar industry, it is essential to maximize sugar recovery. The vertical cooling crystalliser maximizes the exhaustion of molasses, reducing its purity by cooling the massecuite.

Optimized pay back

The purity drop achieved in molasses is between 5 and 10 points.
The exhaustion is maximized by a combined control of massecuite viscosity and cooling temperature.
The electricity consumption is lowered (0.03 to 0.05 kWh/tc).
A low temperature difference is kept between massecuite and water (10°C).

Low maintenance

The cooling tubes are fixed and welded outside the equipment (preventing possible leak in the massecuite).
The massecuite cools down to  40°C in one single equipment (with one single drive system).
A planetary gear drive is fitted to the equipment.
The system is clean with no hydraulics.


It is a vertical system with small foot print.
There is no cascade cooling (one single unit), compared to horizontal crystallisers.
The heat exchange coefficient is high and S/V optimised for each project.
