US 5,096,744 A · Granulating and coating apparatus and granulating and coating method using the same

Abstract

A method of performing granulating, coating, drying of a powdry or granular material having a relatively minute particle diameter and an apparatus therefor. A nozzle for supplying the powdery or granular material and a nozzle for supplying a coating liquid are parallelly provided at adjacent positions where air streams dispersed from the both nozzles are not in contact with each other and directed to the interior of a processing cylinder. The two nozzles are connected to compressed air sources independently of each other. Drying air-stream blow-in openings are provided on the way from collision of the powdery or granular material and the coating material to catching thereof. Drying air streams are supplied from a direction tangent to the processing cylinder having a circular section.

Dependent claims

A coating apparatus comprising:

a vessel;
first means for supplying a flow of an article to be coated in a first direction into said vessel;
second means for supplying a flow of a coating material into said vessel, said said second means being disposed so that the coating material flows substantially in said first direction and collides with said article flow at a downstream location from said first and second means;
and,
means for supplying at least one air stream of drying air into said vessel, said air stream being in a second direction substantially perpendicular to said first direction and downstream of said collision location.
