PURPOSE: A method of manufacturing a vacuum roasting plate with a heat pipe in which a meat is not burnt is provided to shorten a time of roasting a meat by heating a vacuum firing plate by changing water stored in a vacuum firing plate to a steam at a low temperature when burning a meat. CONSTITUTION: A method of manufacturing a vacuum roasting plate with a heat pipe in which a meat is not burnt comprises the following steps: an upper plate manufacturing step aims to manufacture an upper plate (1) in which a bottom is opened, and which is formed as an arch shape; a lower plate manufacturing step aims to manufacture a lower plate (2) in which a vacuum installation unit (50) is comprised, and in which a support stone part (2a) supporting a lower side of the upper plate is protruding to an upper side, and in which a top is opened; a water storage step aims to store a cold water inside the lower plate; a firing plate welding manufacturing step aims to manufacture a firing plate (5) by welding an edge of the lower plate and the upper plate after the support stone part adheres closely to a lower side of the upper plate by settling the upper plate on an upper side of the lower plate in order to form a space part inside the upper plate and the lower plate; a firing plate vacuum formation step aims to make an inside of the firing plate to a vacuum condition by connecting a vacuum inhalation hole to a vacuum installation unit formed on the firing plate; and a firing plate vacuum keeping step aims to maintain an inside of the firing plate to a vacuum condition by finishing the vacuum installation unit and by separating the vacuum inhalation hole from the firing plate at the same time. |
