Title:
METHOD FOR PREPARING HARD CAPSULE AND HARD CAPSULE PREPARED THEREBY
Document Type and Number:
WIPO Patent Application WO/2018/101662
Kind Code:
A1
Abstract:
The present invention relates to a method for preparing a hard capsule, comprising the steps of: (1) preparing an aqueous composition for a hard capsule by mixing a water-soluble cellulose ether, an alcohol, and water; (2) dipping a mold pin, having been preheated to 35-55°C, in the aqueous composition for a hard capsule, and then recovering the same; and (3) drying the recovered mold pin in a temperature range of 20-55°C. According to the present invention, a high-quality hard capsule can be prepared even if a mold pin preheated to a low temperature of 55°C or lower is used and a drying process at 55°C or lower is carried out, and, resultantly, capsule costs can be reduced by decreasing energy costs.
