Embodiments of the present application relate to a single arm rotary vacuum oven as shown in fig. 1. The single arm rotary vacuum oven comprises a double cone heated kettle 100, a vacuum tube 120 and a cylindrical microporous filtration device 130 for separating gas from solid particles. The double-cone heating kettle 100 is provided with a feeding port 102 and a discharging port 104, and the inner wall of the double-cone heating kettle 100 is provided with an electric heating element 106. The vacuum tube 120 is communicated with the interior of the biconical heating kettle 100, and the cylindrical microporous filtering device 130 is arranged in the biconical heating kettle 100 and is communicated with the vacuum tube 120. In one embodiment, the cylindrical microporous filter device 130 includes a sealed end and an interface end for a filter device interface in communication with a vacuum tube, the sealed end having a height greater than the interface end. Preferably, the sealed end is curved and convex away from the cylindrical microporous filter apparatus 130 to prevent material from depositing on the sealed end. Preferably, the cylindrical microporous filtering device 130 is arranged in parallel with the inner wall of the double-cone heating kettle 100 or the anticorrosive coating 110.

Biconical heating kettle 100 may be used to heat a material and evaporate water from the material, thereby drying the material. Vacuum tube 120 may be used to draw moisture-laden gas from bi-conical autoclave 100, thereby drying the material. The cylindrical microporous filtration unit 130 allows the gas in the double-cone heated kettle 100 to be separated from the solid particles. Specifically, first, material may be fed into the bi-conical kettle 100 from a feed inlet 102 on the bi-conical kettle 100 and may be heated by an electrical heating element 106 disposed on the inner wall of the bi-conical kettle 100.
