Mixing and kneading machine

摘要

A mixing and kneading machine comprises a rotating shaft with four circumferentially juxtaposed kneading members, which have an angle of inclination bringing about an axial feed action. Another shaft rotates four times faster. The faster rotating shaft has kneading members with a four times greater slope than the kneading members on the slower shaft. A faster axial product feed in the casing part surrounding the more rapidly rotating shaft is prevented by baffle plates provided in said casing part, so that a narrower residence time distribution for the product is obtained.
