Abstract
A steam or reactant system is provided for a roller compactor to provide improved compaction or functional characteristic of powdered materials, such as active pharmaceutical ingredients. The steam or reactants can be added through conduits terminating in nozzles adjacent the nip zone of the compaction rollers. The injection nozzles can be directed tangentially from the above the rollers or laterally from the sides of the rollers. In one embodiment, the moisture is in the form of steam. The resulting compacting sheet has improved compaction characteristics and reduced compression variability.
