Abstract
The utility model particularly relates to an erythritol's continuous crystallization device specifically includes erythritol dissolving kettle (8), continuous nucleation system, mixes the suspension and mixes ejection of compact crystallizer (7), dissolves the pipe connection of analysing between agent reinforced cauldron (6) and the above -mentioned equipment. The utility model discloses the continuous nucleation system that erythritol's continuous crystallization device adopted is a two -layer same pipe spreader, analyses agent and erythritol's flash mixed through intraductal exsolution, but the intraductal outflow velocity ratio of accessible regulation and control is gone back to the stable crystal seed of production quality (crystal seed quantity and particle size distribution ) not only, produces anticipated quality and particle size distribution's crystal seed conveniently. Compare in traditional erythritol intermittent type crystallization equipment, the utility model discloses still have low, the advantages such as rate of equipment utilization is high, loading and unloading capacity is big, degree of automation height of running cost.
