Beschreibung
Zusammenfassung:	A pan-coating device for performing coating by spraying a coating liquid onto powder (17) in a rotary container (1) using a spray gun (16), wherein the spray gun (16) uses an HVLP type spray gun at a coating liquid pressure of not higher than 0.2 MPa and with a used air volume of 200 to 400 l/min, thereby significantly reducing spray gun contamination and maintaining a stable spraying condition for an extended time. L'invention concerne un dispositif d'enrobage en cuve permettant d'appliquer une couche d'enrobage par vaporisation d'un liquide de d'enrobage sur une poudre (17) contenue dans un récipient (1) rotatif au moyen d'un pistolet (16) de vaporisation. Le pistolet de vaporisation est du type HVLP (grand volume, faible pression), la pression de vaporisation du liquide de revêtement ne dépasse par 0,2 Mpa et le volume d'air utilisé est compris entre 200 et 400 l/min ce qui permet de réduire sensiblement la contamination du pistolet et de maintenir des conditions de vaporisation stables pendant une durée prolongée.
