强制循环结晶器是最常见的结晶器类型。它设计简单、易于操作,通常用在相对平缓或反向溶解度变化的产品的蒸发结晶,或相对粘稠的介质,以及结垢是主要问题的应用中。它的机械能输入较高且二次成核率也较高,因此在不需要大晶体时,它就是最佳的解决方案。
强制循环结晶器由四个基本组件组成:
所需固体密度的浆料从结晶器罐循环通过换热器,过热并返回蒸发室。过热通过蒸发来释放,而不断变化的过饱和度导致悬浮晶体的生长。蒸出的溶剂被引导至后续工艺步骤,或通过再压缩系统来实现内部重新使用。


GEA’s past fiscal year was one of significant growth and further profitability gains. In particular, the technology group substantially increased order intake, with all divisions contributing here. GEA also made progress in all Mission 30 strategic growth areas. In addition, GEA met key interim targets under its climate plan ahead of schedule. Major milestones in fiscal year 2025 were admission to the DAX index, the award of one of the largest contracts in the company’s history, and streamlining of the corporate structure.
