The invention relates to a biconical rotary vacuum drying system, which comprises a biconical rotary vacuum drying main machine, a condenser, a gas-liquid separator, a vacuum pump, an oil pump, a hot oil tank, a vacuumizing pipe, an oil supply pipe and an oil return pipe, wherein the vacuumizing pipe extends into a cylinder body of the biconical rotary vacuum drying main machine from the inner cavity of a driving half shaft and the pipe hole of a driving shaft base; the oil supply pipe extends into an oil inlet cavity from the inner cavity of a driven half shaft and a pipe hole on a baffle; and two built-in oil supply branch pipes which are arranged horizontally on front and back sides are arranged on the middle part of a clamp sleeve of the cylinder body and are communicated with an oil inlet cavity of a driven shaft base. By the biconical rotary vacuum drying system, heat conducting oil can be distributed to integral clamp sleeve space uniformly to ensure the uniformity of clamp sleeve heating, the problem that biconical rotary vacuum drying is 'semi-hot and semi-cold' for a long term is solved, the quality of products and the work efficiency are improved, and energy is saved. In the biconical rotary vacuum drying system, solvents are recovered by a gas condenser and a liquid separator.
