Ambros Schmelzer & Sohn zig-zag concentric sifter for grain cleaning

The zig-zag concentric sifter from Ambros Schmelzer & Sohn (ID 286) represents a clear improvement on the existing system thanks to the development of air-blast sifting technology.
Innovative deflectors inside the machine make the product move in a zig-zag pattern. This allows the product to be aerated several times and cleaned thoroughly.
The decisive innovation lies not only in the modified product flow but above all in the effective measurement of losses by means of piezo sensors. These sensors make it possible, for the first time, to measure directly within the blower control system.
The air volume of the blower can thus be regulated according to the product to be cleaned and on the basis of online loss measurements, resulting in a loss reduction of less than 0,05 percent. This is a significant improvement to the cleaning process.
