Abstract (en)
[origin: EP1279745A1] To produce large sugar crystals of ≥ 5 mm and preferably ≥ 8 mm, in batches, the crystals are developed by vapor crystallizing in a crystallizing vessel. A relative movement is generated between the developing crystals and the over-saturated sugar solution, to give the crystals a floating movement. To produce large sugar crystals of at least 5 mm and preferably at least 8 mm, in batches, they are developed by vapor crystallizing in a crystallizing vessel. A relative movement is generated between the developing crystals and the over-saturated sugar solution, to give the crystals a floating movement. The relative movement is developed by a rising flow of the sugar solution, without any mechanical action, controlled by the water content recovered from evaporation. The heating is controlled to maintain the over-saturation of the sugar solution at a constant level. The assembly also has a heated sieve base, and a separation system for newly-formed fine grains in a collection vessel which calms the flow.
