Abstract
The invention relates to a fluidised bed system (1) comprising a plurality of granulation units (2), arranged so as to be functionally parallel, for producing pharmaceutical granules, each granulation unit (2) comprising: a fluidised bed container (3), an inlet (4) and an outlet (5) on said fluidised bed container (3), a fluid supply (6) and a fluid discharge (7) on said fluidised bed container (3), and at least one injection nozzle (8) for injecting a processing substance into the fluidised bed container (3), as well as a control unit for adjusting processing conditions within each granulation unit (2).
Claims14
A fluidized bed installation (1) comprising
- (i) a plurality of granulation units (2) for the production of pharmaceutical granules, wherein each granulation unit (2) comprises:
- a fluidized bed tank (3),
- an inlet (4) and an outlet (5) on the fluidized bed tank (3), the inlet (4) configured to deliver a pulverulent solid to the fluidized bed tank (3) and the outlet (5) configured to remove a finished product from the fluidized bed tank (3),
- a fluid inflow (6) and a fluid outflow (7) on the fluidized bed tank (3), the fluid inflow (6) configured to deliver a working fluid to fluidized bed tank (3) and the fluid outflow (7) configured to remove the working fluid from the fluidized bed tank (3), and
- at least one spray nozzle (8) for spraying a processing substance into the fluidized bed tank (3),
- (ii) an inlet line (19) configured to deliver the pulverulent solid to the granulation units (2),
- (iii) an outlet line (10) configured to remove the finished product from the granulation units (2), and
- (iv) a control unit (12) configured to adjust process conditions within each granulation unit (2),
- wherein the inlets (4) of all of the plurality of granulation units (2) are connected in parallel to the inlet line (19), and
- wherein the outlets (5) of all of the plurality of granulation units (2) are connected in parallel to the outlet line (10).
