    Abstract: The present invention generally relates to particulate compositions and methods for making the compositions. It specifically relates to improved spray drying methods that substantially reduce the production of small particles that pose industrial hygiene concerns for factory workers and product consumers. In a composition aspect, the present invention provides an atomized aqueous composition. The composition is formed using a spray-drying apparatus. It includes 0.001 to 0.10 weight percent of a polymer, which is selected from a group consisting of a cellulose-based polymer, a gum, and a synthetic polymer. It further includes at least one polypeptide, which is present in the aqueous composition at a concentration greater than 0.01 weight percent.

    Abstract: A fluidized bed coating apparatus is provided and includes a fluid inlet adapted to be connected to a source of fluidizing fluid. The fluid inlet has an entrance opening having a first diameter and an exit opening downstream of the entrance opening. The exit opening has a second diameter that is larger than the first diameter. The inlet also includes an expanding inlet section, between the entrance opening and the exit opening, that has an average diameter that increases in a direction from said entrance opening to said exit opening. A fluid distribution plate is provided adjacent the exit opening and includes a plurality of through-passages to allow the even and distributed passage of a fluidizing fluid therethrough. A chamber having a chamber inlet and a chamber outlet is provided and the fluid distribution plate is positioned between the exit opening and the chamber inlet. The chamber includes at least a first diverging section having an average diameter that increases in the direction from the chamber inlet downstream toward the chamber outlet. The symmetrical design of the coater provides an evenly distributed flow of fluid that enables efficient and complete fluidization and coating of very large particle beds.
