A transfer and coating apparatus transfers a component from a conveyor to a coating station for application of a coating. The transfer apparatus includes a mast that can move about orthogonal axes in a horizontal plane and a mast having a carriage that can move vertically. The carriage includes a hook that swings about a horizontal axis relative to the mast for movement of the component in the horizontal direction. A sway bar extends between the hook and component to inhibit movement about a horizontal axis. The component is delivered to an upper compartment of a coating apparatus where it can be lowered in to a lower compartment containing coating material. Excess coating material is removed by an array of nozzles in the upper compartment as the component is raised from the coating material.

Disclosed is a microcapsule including a core having an oxidizable active (OA), the outer part of said core being in a solid form, and a water insoluble coating obtained from an encapsulating agent (EA), with the coating surrounding said core. In particular, the EA can be water soluble or organic solvent soluble, in particular in ethanol. The microcapsule can also include an EA in which the water solubility is pH-dependent. Also, the core does not contain a metal oxide, and the coating does not include a disintegrant, such as sodium starch glycolate. Also disclosed is a process for preparing the microcapsules.

摘要:
A composite particle including a core with at least one carrier material; a fluidizing material layer on the surface of the core; and an outer layer comprising nanoparticles of an ingestible material distributed in at least one matrix-forming material. A process of making the composite particles includes the steps of dry coating carrier particles with a fluidizing material; preparing a suspension of nanoparticles of an ingestible material distributed in a matrix-forming material; and fluid bed coating the carrier particles with the suspension. The process and products provide quick dissolving composite particles which can be used for delivery of poorly water soluble ingestible materials in suitable dosage forms. The process of the invention reduces or prevents particle agglomeration during fabrication of the composite particles to enable delivery and quick redispersion of nanoparticles of the ingestible material from a dosage form.
摘要:
A chelating agent prevents or mitigates discoloration for clumping pet litter containing raw clay seeds coated with bentonite. The chelating agent can be added directly to the raw clay seeds and/or dry mixed with bentonite prior to coating the seeds with the bentonite. Preferably, preheating and agglomeration steps are eliminated to thereby significantly reduce energy and water consumption.
