HEAT TREATMENT EQUIPMENT AND ITS CONVEYING TRAY

PROBLEM TO BE SOLVED: To provide a heat treatment equipment and its conveying tray capable of manufacturing uniform products with high productivity. SOLUTION: The heat treatment equipment is equipped with a cylindrical heating body, a conveying tray conveying raw material from the one end in the heating body toward the other end, and a heating means of the heating body. In the heat treatment equipment, the raw material in the conveying tray is constituted so as to be heat treated during passing through the heating body, and the outer peripheral surfaces of a bottom part and both sides on the right and left of the conveying tray, are formed into a sectionally arcuate shape by being incurvated with the curvature along the inner peripheral surface of the heating body. In the conveying tray of the raw material used for the heat treatment equipment equipped with the heating body having a circular cross section which conveys and heats the raw material, the conveying tray is formed into a sectionally arcuate shape by being incurvated with the curvature along the inner peripheral surface of both sides on the right and left.
