Device for batching of free-flowing preservatives for processing of feed grains when flattening

Among chemical preservatives, liquid organic acids are most often used to preserve grain, for which various dosing devices are used in the grain mass. However, the use of effective and cheaper dry products, such as sulphur powder, is constrained by the lack of application devices. In this regard, the purpose of our work was the development of a dosing device designed for the metered supply of powdered preservatives laid for storage of raw flattened feed grain. As a result of the research physical and mechanical properties of powdered sulfur were established, which allowed one to find a structural solution to the problem of dosing of such material. Production tests of the prototype of the developed device showed its energy and economic efficiency when preserving raw feed grain with powdered sulfur.
