| Zusammenfassung: | To provide a method for producing solid particles which suppresses adhesion of fine particles.SOLUTION: There is provided a method for producing solid particles which comprises the following steps 1 to 3: a step 1 of heating a raw material composition comprising an oily component to impart fluidity, a step 2 of granulating the raw material composition to which fluidity is imparted to form a granular raw material and a step 3 of dropping the granular raw material into a powder to coat the surface of the granular raw material with the powder, wherein in the step 3, an air flow is given from a side surface of the dropping track of the granular raw material.SELECTED DRAWING: Figure 2
【課題】微粒子の付着が抑制された固形粒子の製造方法を提供する。【解決手段】下記工程１～工程３を有する固形粒子の製造方法であって、工程１：油性成分を含む原料組成物を加熱して流動性を付与する工程、工程２：流動性を付与した前記原料組成物を粒状化して粒状原料を形成する工程、工程３：前記粒状原料を粉体中に滴下して、前記粒状原料の表面を前記粉体で被覆する工程、前記工程３において、前記粒状原料の滴下軌道の側面から気流を付与する、固形粒子の製造方法。【選択図】図２ |
