Patent ID: 7429407

Claim:
A non-fluidized bed process for coating bodies comprising: producing an upward spray of coating fluid by means of a two-fluid nozzle to create a coating zone, and contacting said bodies with said spray of coating fluid in said coating zone; wherein, before contacting said bodies with said spray, providing the bodies with a spinning movement by a central impact of gas jets directed upward to intersect the centerline of said spray; guiding the spinning bodies by said gas jets towards a central position over the two-fluid nozzle, thereby increasing the number of suspended bodies contacting the spray; providing atomization gas to the two-fluid nozzle in an amount less than the one which, after moderation by means of muffling gas, would scatter the bodies in the spray zone; and pneumatically muffling the atomization gas just above the nozzle to reduce the body scattering effect thereof; and further wherein, said bodies are pneumatically transported in said coating zone in a non-fluidized state.
