Title: The Innovative Contributions of Heinz List
Introduction
Heinz List was a notable inventor known for his contributions to the field of mixing technology. He was based in Pratteln, Switzerland, and held two patents during his career. His inventions have had a significant impact on the efficiency and effectiveness of kneading processes in various industries.
Latest Patents
Heinz List's latest patents include the "Multi-spindle kneading mixer" and the "Multi-spindle kneading mixer with fixed kneading counterelements." The first invention relates to a multi-spindle kneading mixer featuring at least two axis-parallel agitator shafts that engage with one another. One of these shafts is designed as a disk shaft, into which kneading elements of a kneading shaft engage. These kneading elements are responsible for scraping the product off the disk surfaces and pressing it into a kneading gap formed by the kneading element and the opposite disk surface. This design allows for efficient axial movement of the product between the disk surfaces. The second patent describes a multi-spindle kneading mixer equipped with intermeshing shafts, where one shaft has disk elements cleaned by a second agitator shaft. This configuration allows for intensive mixing and kneading, enhanced by the inclusion of fixed kneading counterelements in the housing for thorough cleaning of the agitator shafts.
