Mixing and kneading machine for continuous treatment processes as well as procedures for carrying out continuous preparation processes by means of a mixing and kneading machine.

摘要

A mixing and kneading machine (1) for continuous treatment processes has in a housing (2) rotating and translationally moving at the same time in the axial direction of the screw shaft (3). To increase the efficiency of the machine in relation sustained to the material throughput per unit time, the worm shaft (3) at least four groups of evenly distributed over the circumference screw wings (4a, 4b, 4c, 4d), wherein the respective group of a consists plurality of axially successively arranged screw vanes. The outer diameter (Da) of the screw shafts located between 100 and 400 millimeters. The speed of the screw shaft (3) is between 5 and 300 1 / min. Such a trained mixing and kneading machine (1) is particularly suitable for the preparation of various food compositions as well as for the preparation of raw materials for the plastics industry, in particular to produce a reactive extrusion.
