<p>The present invention relates to reuse of a gelatin net generated during a process of manufacturing a gelatin capsule, and more particularly, to a method and an apparatus for extracting high purity of gelatin from the gelatin net by removing an additional material, specifically, its color contained in the gelatin net in order to reuse the gelatin as a material for manufacturing a gelatin capsule. To this end, according to the present invention, the gelatin scrap is washed for a post-process and foreign substances are filtered by sequentially performing a general filtering scheme, a micro-filtering scheme and an ultra-filtering scheme after a gelatin scrap is dissolved with solvent. Then, in ion separation step, a coloring material is removed and concentrating and drying processes are performed.</p> |
