  • Patent number: 11759976
    Abstract: A continuous granulation system for obtaining conditioned granules is disclosed. The system comprises a processor configured to produce a continuous flow of granules at an outlet of the processor. The system also comprises a collection chamber positioned downstream from the processor and configured to collect the granules from the outlet. Further, the system comprises an air displacement device coupled to the collection chamber and configured to create a unidirectional flow of air at the outlet in a direction of the granules exiting the processor and away from the outlet. The unidirectional flow of air conditions the granules obtained in the collection chamber. A continuous granulation method and a continuous granule collection system for obtaining the conditioned granules is also disclosed.

  • Patent number: 11576855
    Abstract: The present disclosure concerns effervescent compositions and methods of making and using the same. In some embodiments, the disclosed effervescent compositions are formed from an input blend comprising an acid and a base by granulating the input blend in a twin-screw processor. The granules formed from the input blend can be formed by an in situ granulating agent, which can be a portion of the acid that melts during granulation. In some embodiments, the effervescent compositions can be made using a twin-screw processor comprising an intake zone for receiving an input blend comprising an acid and a base; a granulation initiation zone for melting only a portion of the acid to serve as an in situ granulating agent; a granulation completion zone for granulating the input blend; and an outlet for discharging the granules.
