The invention provides a high-temperature drying device for new chemical materials. The high-temperature drying device comprises a drying stirring cylinder, a mixing motor, a feeding pipe, a sealing cover, a discharge pipe, a discharge fan, an adjustable stirring roll-over stand structure, an adjustable side protection frame structure, an adjustable protection belt structure, an eduction pipe, an eduction valve, an electric heating pipe, a bottom bracket, a height-adjustable bracket structure, a power switch and a fan switch, wherein the mixing motor is mounted at the middle upper part of the drying stirring cylinder through bolts; the feeding pipe is inserted into the left side of the upper part of the drying stirring cylinder; the sealing cover is inserted into the upper part of the inner side of the feeding pipe; and the discharge pipe is inserted into the right side of the upper part of the drying stirring cylinder. Material leaking holes are formed in the outer sides of spiral material conveying blades correspondingly, materials can be guided downwards from the interiors of the material leaking holes, and then the drying effect of the materials is improved; and a rubber protective pad is glued to the outer side of the side edge fixing frame, so that the periphery of the drying stirring cylinder can be conveniently protected during use.
