Mixer for dry concentrated feed

Abstract

Abstract In the production of starch products from corn grain, a number of valuable byproducts are obtained, the bulk of which are pulp, corn extract, crushed corn grain and oilcake. By-products of starch production in the feeding rations of farm animals are mainly used as separate components, which reduces the effectiveness of their use. It is most advisable to feed them in the form of a dry mixture as concentrated corn feed, which is proposed to be cooked in a spiral mixer. The design and technological scheme of the mixer should include a framework with a spiral installed in it, one end of which is fixed to the eccentric of the leading pin and the other to the driven pin of the feed change mechanism with the possibility of horizontal movement. To justify the design and technological parameters and rational operating modes of the mixer, theoretical, laboratory and production tests were performed, their results are presented. Based on the data obtained, the parameters and operating modes of the spiral mixer are substantiated. As a result of production tests, the developed mixer, used in the processing lines for the preparation of crumbly and granular feed, confirmed its operability
