In this research, we propose an on-line measuring method for determining the crystal size distribution in a crystallizer. This method is to suck liquid including crystals out of the stirred-type crystallizer and to instantly observe a silhouette of the crystal in a multiphasic way using the imaging processing system. A variety of information on the crystals, such as the shape, diameter, agglomeration and/or breakage, can be obtained from the reconstructed 3-D images. In this paper, the crystal diameter distributions which are based on 3-D crystal images were measured in several crystallization conditions and two types of crystallizers. As a result, it is found that quantitative information on crystals in a crystallizer can be obtained using this method.

在这项研究中，我们提出了一种在线测量方法来确定结晶器中的晶体尺寸分布。该方法是将含有晶体的液体从搅拌型结晶器中吸出，利用图像处理系统以多相方式即时观察晶体的轮廓。可以从重建的 3D 图像中获得有关晶体的各种信息，例如形状、直径、团聚和/或破裂。本文在几种结晶条件和两种类型的结晶器中测量了基于 3D 晶体图像的晶体直径分布。结果发现，使用该方法可以获得关于结晶器中的晶体的定量信息。
