Abstract

Sugar crystals separated from massecuites are freed from the film of material remaining thereon after centrifuging by treating the crystals in the centrifuge with a small proportion of sulphur dioxide, dissolved in water or diluted with a gas or vapour such as steam. The concentration of the sulphur dioxide is so selected that the run-off, or the mixture of the mother liquor and the run-off, has a pH value not lower than that permissible in its subsequent working up. If the treatment with sulphur dioxide would lower the pH value of the expelled liquids below the desired limit, the crystals are first treated with an alkaline substance such as a solution of lime or sodium carbonate. The treatment with sulphur dioxide may be followed by washing with a suitable liquid, or with a suitable gas or vapour, preferably supplied under pressure. A sulphite, bisulphite, carbonate or carbon dioxide may be used instead of sulphur dioxide.
