In the food field, aggregated particles having high safety and stability, high solubility and low dust value, and aggregated particles having a large amount of active substances such as fragrances are not released early, and Providing aggregated particles having a size of 200 μm, preferably 300 μm or more, that do not vaporize before final use. In order to dry a liquid material sprayed from a liquid supply atomizer Z1, powdery particles are generated by means of a spray drying process using a spray drying agglomeration device in which a spray drying section A is arranged at the top of a chamber. And spraying together with the powdery particles together with the liquid binder inside the integrated fluidized bed B located at the bottom of the chamber of the spray drying agglomeration device, the particles are always in a fluid state at the time of production, Aggregated particles having a size of 200 μm or more having a procedure in which a liquid binder is sprayed by means of a nozzle attached to the lower part of the fluidized bed B or the means of the atomizer structure Z2 are generated in the powder of the dried spray drying section how to.
