METHOD AND APPARATUS FOR RECOVERING HIGH PURITY GELATIN FROM GELATIN NET GENERATED IN GELATIN CAPSULE MANUFACTURING PROCESS

摘要

The present invention relates to a method and an apparatus for recovering gelatin from a gelatin net generated in a gelatin capsule manufacturing process and more particularly, to a recycle of a gelatin for use as a raw material for manufacturing a gelatin capsule by extracting a high purity gelatin through removing an additive, specifically, a coloring included in a gelatin net. To this end, in the present invention, a gelatin net is cleaned in a pre-process, the gelatin net is dissolved by a solvent, and a foreign substance is filtered by sequentially using a normal filtering scheme, a microfiltering scheme and an ultrafiltering scheme, a coloring causing material is removed in an ion separating step, and the gelatin net is concentrated and dried.

主权项

1. A method for recovering high purity gelatin from a gelatin net generated in a gelatin capsule manufacturing process, the method comprising:
an introducing step (a) of introducing the gelatin net generated in the gelatin capsule manufacturing process into a solvent; a mixing step (b) of dissolving the gelatin net while mixing the gelatin net and the solvent, in which the solvent is heated to a predetermined temperature in the introducing step; a separating step (c) of separating a solution, which is obtained during the mixing step (b) or after the mixing step (b), into a solvent layer and a non-solvent layer; a treating step (d) of removing a foreign substance included in the solvent layer obtained from the separating step (c), wherein the treating step (d) further comprises an ion separating step (e) for removing a coloring causing material among additives included in the gelatin net; and a concentrating and drying step (f) of concentrating a pure gelatin obtained from the ion separating step (e) to provide convenience of storage and usage.
