Abstract
The apparatus serves particularly for the continuous charging of extractors for oil-containing vegetable raw materials, wherein highly flammable, low-boiling solvents, such as benzene, hexane, heptane etc. are used as extractants or solvents for the glyceride constituents to be extracted. The apparatus, which is provided between the preparation (comminution) of the raw material and the extraction plant proper, comprises an equalizing vessel having a mixing zone and a double screw disposed at an inclination with respect to the horizontal wherein the spacing of the screw turns, in the area of the vessel, increases continuously in the direction towards the discharge outlet. The inclination of the screw is such that the space defined by the base of the screw and an imaginary line is constantly filled. Equalizing vessel, mixing zone and screw are interconnected to form a tightly sealed unit.
