An apparatus for manufacturing a capsule by using vegetable gelatin is provided. Heating units are installed in a gelatin feeding line, which feeds gelatin in the form of a sheet, and a molding line to feed the gelatin in a predetermined temperature. The molded capsule is conveyed through a conveyer so that the molded capsule is stably dried and cured and a temperature of the conveyer is adjusted to control a temperature of the capsule. A length of the drying line is maximally increased within a narrow space, so that a film of the capsule made of the vegetable gelatin is gradually cured and dried without abrupt temperature variation, thereby preventing crack from occurring in the capsule, and preventing bonding parts of the capsule from being torn to improve the commercial value of the capsule.
