    摘要: Granules are prepared containing an admixture of protein and salt layered over an inert particle. A preferred amount of salt is about between 63.7 and 84.3% of the total weight of the admixture. Proteins include pharmaceutically important proteins such as hormones, or industrially important proteins such as enzymes including proteases, amylases, lipases and cellulases capable of hydrolyzing substrates such as stains. Inert particles include inorganic salts, sugars, sugar alcohols, small organic molecules such as organic acids or salts, and minerals such as clays or silicates. A binder such as starch or polyethylene oxide may be mixed in with the admixture. A barrier material such as an inorganic salt or organic acid or salt may be in the admixture or coated over the admixture layer. A coating layer of a soluble or water dispersible film-forming polymer may be between the inert particle and admixture layer and/or over the admixture layer. The granules may also contain plasticizers, extenders, lubricants, pigments and anti-agglomeration agents. A preferred method for preparing the granules is by spraying a solution or slurry of the admixture onto the inert particles while fluidized in a fluid-bed coater.

    摘要: 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.

    摘要: The invention provides methods, compositions, systems, and kits that include an enzyme/substrate co-delivery system. The liquid delivery system includes at least one enzyme encapsulated in a water-soluble polymeric matrix and a substrate for the enzyme in a carrier liquid in which the polymeric matrix is insoluble. When water is added, the polymeric matrix is solubilized and enzyme is released from the matrix, permitting catalytic action upon the substrate.
