Each mixer includes blade groups (24-27 and 28-31) with opposite inclinations as viewed in the rotation direction, such that while raising and lowering the mixers layer by layer a part of the substance is lifted mechanically while another part is pressed downward. The apparatus includes of a mobile unit (1) which can be fixed and centered in an exact position relative to the pot (2).
