The invention discloses a vegetable fat extraction and separation device and method and belongs to the technical field of
vegetable oil extraction. Comprising a tank body, a material cage, a driving mechanism, an
extrusion mechanism, a stirring mechanism and a suction mechanism. The tank body is provided with a
temperature control unit for accommodating an extraction
solvent and regulating and controlling the temperature of the extraction
solvent; the material cage is used for containing
plant raw materials, and a filtering structure is arranged on the wall of the material cage. The driving mechanism is connected with the material cage and is used for driving the material cage to perform compound motion in the tank body, so that the
plant raw materials are in full contact with the extraction
solvent. And the
extrusion mechanism is arranged above the tank body and is used for applying pressure to the
plant raw materials in the material cage. The stirring mechanism is arranged in the tank body and is used for stirring the extraction solvent in the tank body. And the suction mechanism is communicated with the tank body and is used for extracting the separated
grease. The device is particularly suitable for laboratories and small and medium-scale production, can complete automatic
continuous operation of
raw material infiltration, extraction and separation, and realizes efficient, energy-saving and environment-friendly
grease extraction.
