摘要:
The process for recovering vegetable oleaginous substances from oil-containing natural substances comprises a series of continuous combined pressing and extraction steps to increase and simultaneously to guarantee a high quality product for different kinds of natural substance starting materials. This is accomplished by subjecting the natural substances, conditioned and comminuted if necessary, after mixing with a solvent phase containing some oil to an intensive processing, mixing and extraction in the shear field of at least one rotor-stator unit and subsequently feeding the resulting liquid phase, through a filter if necessary, to a distillation column. The solid phase is extracted in successive stages until a residual oil content of 1% is reached and the solvent is fed back to a solid phase in a counterflow. The process as defined in my invention is universally applicable to all fat and oil-containing natural substances using suitable fluid extraction means. An apparatus for performing this process is also provided. A variety of rotor-stator assemblies are provided for the rotor-stator unit as defined in the nature of the natural substances being processed.
