NOVELTY - The utility model claims a low temperature drying device, especially relates to a solid low temperature drying device for preparing graphene oxide powder. The purpose of the utility model is to provide a solid low temperature drying device for preparing graphene oxide powder capable of stirring the graphene oxide powder. The utility model claims a solid low temperature drying device for preparing graphene oxide powder, comprising a base, a shell, a sliding plate, a baffle plate and an observation window, the base is top part with a shell, the middle of the upper part of the shell is slidingly provided with a sliding plate, the front side of the lower part of the inner side of the shell is slidingly provided with a striker plate, the front side of the upper part of the inner side of the shell is connected with an observation window. The utility model starts the stirrer, the stirrer rotates to stir the graphene oxide powder, so that the graphene oxide powder is heated uniformly, accelerating the drying speed of the oxidized graphene powder, and the drying effect is good.
