摘要
A process for continuously crystallizing alpha monohydrate dextrose from dextrose-containing liquours. The process is operated isothermally and produces a lean phase massecuite. According to the process, a rate of agitation is employed, within a reaction zone operated in a continuous mode, which permits linear growth of crystals to occur at a growth rate which is surface reaction controlled. The process may be combined with a batch process by feeding lean phase massecuite from the process into a second reaction zone operated in a batch mode. This is done at a constantly declining temperature and produces a rich phase massecuite. The batch process stage is also continuously agitated, but at a slower rate than the first stage continuous process to prevent excessive attrition of existing crystals while maximizing crystal yield.
