Patent ID: 7878143

Claim:
A film-forming apparatus which forms a film, comprising: a mixing section which mixes material particles for forming the film and core particles having a particle size greater than that of the material particles to adhere the material particles onto each of the core particles; a separating section having a collision wall against which the core particles, each with the material particles adhered thereonto, collide to separate the material particles and the core particles; a transporting mechanism which transports each of the core particles, onto each of which the material particles adhered, from the mixing section to the separating section; a controller which is provided on the transporting mechanism and which controls a supply amount of the core particles to the separating section; a fluidizer which generates a fluidized bed of the core particles and which is provided between the mixing section and separating section; an aerosol generator which is connected to the separating section and which generates an aerosol by dispersing the material particles, separated from each of the core particles at the collision wall, in a carrier gas; and a nozzle which is connected to the aerosol generator and which ejects the aerosol.
