The production system includes a buffer reservoir (22), a wider than the inlet aperture (7), which is not separated from the mixing cavity. It contains string parts. There is an element at the small aperture (6) of the mixer or storage container. The minimum spacing between the mixing shaft and the chamber wall is at least 4 mm. The mixer shaft has a cross-section surface not more than 20% that of the cross-section surface between the chamber walls. |
