The present invention relates to an apparatus for manufacturing a hot pack with enhanced sealing quality and sealing rate, comprising: a worktable for performing an operation of manufacturing a hot pack； a first packing material supply part for supplying a first packing material onto the worktable； a heating agent supply part for supplying a heating agent corresponding to a granular material onto the first packing material of the worktable so that the heating agents can be set in a plurality of areas spaced from each other in the front-to-rear and width directions； a second packing material supply part for supplying a second packing material to cover the plurality of heating agents set on the first packing material by the heating agent supply part； a sealing part for pressurizing the heating agents set between the first and second packing materials to bind the first and second packing materials and form a pouch accommodating the heating agents； and an air injection part installed at a rear end of the heating agent supply part to remove heating agent scraps scattered between the heating agents set through air injection. According to the present invention, the heating agent scraps may not remain due to the injection of air into a setting area of the heating agents. When setting the heating agents onto the packing materials, the heating agents may be physically guided to concentrate on an area in which the heating agent is set, and thus the heating agents may be prevented from scattering on the packing material. Accordingly, when sealing the packing materials for the heating agents, the heating agent scraps may not be present in the sealing area, thereby achieving excellent sealing quality, an excellent sealing rate, and an increased production speed for enhanced productivity as well.COPYRIGHT KIPO 2020본 발명은 핫팩 제조 작업을 수행하기 위한 작업대； 상기 작업대 상에 제 1 봉지재가 공급되도록 하는 제 1 봉지재공급부； 상기 작업대 상의 제 1 봉지재 상에 입상물에 해당하는 발열제를 전후 및 폭방향으로 이격되는 다수의 영역에 셋팅되도록 공급하는 발열제공급부； 상기 발열제공급부에 의해 상기 제 1
