Abstract Spray fluidized bed coating is an established process for the treatment of solid particles. Commonly fluidized beds are heated convectively. Another method is inductive heating by electrically conductive particles. In this work spray coating with inductive heating is investigated. Coating experiments with convective or inductive heating and different process parameters (temperature, spraying rate, initial particle diameter, initial bed mass) were realized. Moisture content, particle size distribution and apparent density of the particles were measured, as well as the thickness and porosity of the layer created on the initial particles. Similar results can be obtained by both heating methods, advantages of inductive heating are discussed as well as limitations.

流化床感应加热：喷涂工艺

摘要 喷雾流化床包衣是处理固体颗粒的既定工艺。通常流化床是对流加热的。另一种方法是通过导电颗粒进行感应加热。在这项工作中，对感应加热喷涂进行了研究。实现了对流或感应加热和不同工艺参数（温度、喷雾速率、初始粒径、初始床层质量）的包衣实验。测量了颗粒的水分含量、粒度分布和表观密度，以及在初始颗粒上形成的层的厚度和孔隙率。两种加热方法都可以获得类似的结果，讨论了感应加热的优点和局限性。
