This work presents a novel design of a continuous crystallizer, the Archimedean screw crystallizer reactor (ASKR) with integrated Archimedean screw as conveying element. By the screw, the axial motion of the product solution is initiated, and an undesired axial mixing is restricted. This structure results in a narrow residence time distribution and, thus, promotes a defined product quality. In order to quantitatively assess the flow characteristics of the crystallizer and to highlight the influence of variable operating parameters such as rotational speed and volumetric flow, investigations of the residence time behavior with variation of the operating parameters are reported.

新型阿基米德螺杆结晶器/反应器的停留时间特性

这项工作提出了一种连续结晶器的新颖设计，即阿基米德螺杆结晶器反应器（ASKR），其中集成了阿基米德螺杆作为输送元件。通过螺杆，开始了产品溶液的轴向运动，并且限制了不希望的轴向混合。这种结构导致狭窄的停留时间分布，因此提高了确定的产品质量。为了定量评估结晶器的流动特性并强调可变操作参数（如转速和体积流量）的影响，报告了随着操作参数变化而对停留时间行为的研究。
