The favorable amino acid and fatty acid composition, the high protein content and the good digestibility make fish meal a high-quality feed (ingredient) for many animals. In the fish meals offered, fish species are used that are of little relevance for human consumption, e.g. fish rich in bones such as anchovies. During production and loading, impurities such as foil residues, metals and large bone fragments can hardly be avoided. To clean the product from these, J. Müller has relied for years on a VDK4 hammer mill with upstream cleaning system from Tietjen.
Already more than 2100 Tietjen plants have been installed all over the world since 1959 – from Australia to Zimbabwe, from agricultural businesses to well-known international conglomerates. The following references and projects represent a small selection of these.
