Abstract: Coated bodies and a process, apparatus and article of manufacture for coating bodies in a non-fluidized state, including tablets, by producing an upward spray of coating fluid by means of a two-fluid nozzle as defined herein and contacting said bodies with said spray of coating fluid in a non-fludized state; wherein, before contacting the bodies with said spray, providing the bodies with a spinning movement by acentral 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 spray body scattering effect thereof.

Abstract: A 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 the bodies with the spray of coating fluid in the coating zone; wherein, before contacting the bodies with the spray, providing the bodies with a spinning movement by a central impact of gas jets directed upward to intersect the centerline of the spray; guiding the spinning bodies by the 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, the bodies are pneumatically transported in the coating zone in a non-fluidized state.

Abstract: Bodies, including tablets, are coated by producing an upward spray of coating fluid by means of a two-fluid nozzle as defined herein; before contacting the 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.

Abstract: A non-fluidized bed apparatus for coating tablets has a base plate of which a portion of the upper surface is inclined towards an upward directed two-fluid or three-fluid nozzle. Ducts through the base plate around the nozzle produce jets of process gas in a direction intersecting an imaginary centre line of the spray produced by the nozzle. Atomizing gas from the nozzle is muffled shortly after it has left the nozzle to decrease the upward scattering effect of said gas on the tablets being coated. No partition is used for separating upward and downward flow of tablets during the coating process. In the coating process the amount of atomizing gas supplied to the nozzle is limited to reduce the tablet scattering effect of said gas.
