DRY COATING USING BIAXIAL KNEADER

摘要

It is intended to provide a dry coating method whereby a dry-coated preparation can be produced in a large amount. A method of producing dry binder particles wherein the surface of core particles is dry-coated with a dry binder, which comprises kneading starting materials containing core particles and a dry binder (lauric acid, myristic acid, etc.) in a biaxial kneader. By using this method, a dry-coated preparation can be efficiently produced in a large amount compared with the existing methods. Also, a dry-coated preparation can be efficiently produced in a large amount compared with the existing methods by using a method of producing dry-coated particles characterized by comprising kneading starting material containing core particles, a dry binder and a powder for coating in a biaxial kneader.
