Continuous gas‐solid processes are applied in many industries with particulate products, e.g. for granulation or coating. In this contribution, the residence time behavior in a continuously operated prismatic spouted bed was determined by applying an impulse of magnetizable tracer particles. Experiments were performed with the original configuration and with separation plates including mouse holes of varying size between the different chambers of the ProCell 25 apparatus. It is shown that the shape of the residence time distribution is influenced by the separation plates. In order to quantify the backmixing between the chambers, discontinuous experiments were performed, and the bed mass distribution and the distribution of the tracer were measured and compared to the initial conditions.

连续喷射床中停留时间分布的测量
连续气固工艺在许多工业中都用于颗粒产品，例如造粒或包衣。在这一贡献中，通过施加可磁化的示踪颗粒的脉冲来确定在连续操作的棱柱形喷头床中的停留时间行为。实验是在原始配置下进行的，并在ProCell 25设备的不同腔室之间使用了包括大小不同的鼠标孔的隔板。结果表明，停留时间分布的形状受隔板的影响。为了量化室之间的返混，进行了不连续的实验，并测量了床的质量分布和示踪剂的分布并将其与初始条件进行了比较。
