摘要

The machine has a hollow cylindrical rotor (2) provided with outer base slots (4) and inner base slots for inner blades (18) and outer blades (5), where the inner and outer blades are supported in an elliptical housing (1). A hollow round-shaped inner cylinder (6) exhibits a circular cross-section and is positioned in a rotatable manner. The inner cylinder is made of glass and attached to a cover (13). The inner cylinder is attached at a bottom part of the cylindrical rotor. An inner chamber comprises an inlet channel and an outlet channel, where the channels are located in the cover.
