Abstract: A co-rotating twin screw processor for preparing dry granules including an input zone having one or more powder feeders for feeding an input material into the processor, a steam feeder configured to introduce steam as a granulation activating agent in to the processor, a granulation zone for granulating the input material in the presence of steam to form granules, a controller configured to control operation and feed rate of at least one of the powder feeder or the steam feeder such that 2.5 to 5 percent w/w of the steam with respect to the input material is available for granulation, and a discharge zone haring a non-extruding opening for collecting dry granules.

Abstract: A fractional lobe processor is disclosed. The fractional lobe processor comprises an intake zone comprising at least one deep flighted shovel element on each intermeshing screw for receiving a input blend comprising an active substance and an excipient; a granulation zone consisting of only fractional lobe elements, and having a provision for introducing moisture or a binder solution, for granulating the active substance and the excipient; an optional, drying zone for drying the wet granules; and a discharge zone for discharging the granules; wherein the granulation zone is located before the discharge zone and after the intake zone; wherein the drying zone has one or more fractional lobe elements on each shaft; and wherein the granulation zone has a plurality of fractional lobe elements on each shaft.

Abstract: Methods for granulating powder in a single piece of equipment include at least the following: (a) continuously introducing the powder and a granulating fluid to the single piece of equipment; (b) passing the powder and the granulating fluid through a granulating zone of the single piece of equipment to form wet granules; (c) passing the wet granules through a drying zone of the single piece of equipment; (d) optionally passing granules through a discharge zone of the single piece of equipment; and (e) continuously discharging the granules from the single piece of equipment where the single piece of equipment is not a fluid bed processor.

Abstract: Methods for granulating a pharmaceutical powder in a single piece of equipment include at least the following: (a) continuously introducing the pharmaceutical powder and a granulating fluid to the single piece of equipment, (b) passing the pharmaceutical powder and the granulating fluid through a granulating zone of the single piece of equipment to form wet granules, (c) passing the wet granules through a drying zone of the single piece of equipment, (d) optionally passing granules through a discharge zone of the single piece of equipment, and (e) continuously discharging the granules from the single piece of equipment where the single piece of equipment is not a fluid bed processor.

Abstract: The present disclosure relates to a process for preparing granules from an input material or a powder material. The process comprises feeding the input material for granulation in the processor using one or more powder feeders, introducing steam as a granulation activating agent in the processor, granulating the input material in presence of the steam to form granules, and optionally collecting the granules from a discharge zone of the processor, wherein feed rate of the steam into the processor is determined based on feed rate of the input material into the processor. A co-rotating twin-screw processor for preparing granules is also disclosed.
