Determination of the homogeneity of feeds prepared in a device equipped with a screw-knife and finger units

Abstract

Background and Aim. Due to the growing demand for feed, there is a need to develop devices capable of producing highly homogeneous feed mixtures. At the same time, a poorly understood process is the mixing of various components of animal origin, including various bone waste with each other and raw materials remains insufficiently studied. Based on this, we propose a design and technological scheme of a device equipped with a screw knife and finger units, aimed at achieving a high degree of homogeneity in feed mixing.

Materials and Мethods. The study aimed to determine the homogeneity of feed mixing. Eggshells and yolk waste from chicken eggs were loaded into a device equipped with a screw-knife and finger units. Peas were used as a control component. Mixed samples were collected at 2, 4, 6 and 8 minutes after the start of the mixing process.

Results. As a result of experimental studies of feed samples prepared using the developed de-vice equipped with a screw-knife and finger units, the following results were obtained for the ho-mogeneity of mixing of eggshells with yolk waste and the control component, peas: 89.23% after 2 minutes.; 89.445% after 4 minutes.; 89.5% after 6 minutes; 90.8% after 8 minutes.

Conclusion. The developed design and technological scheme of the device equipped with a screwknife and finger units ensured stable performance of the mixing process of various feed com-ponents and, in experiments, proved its effectiveness in achieving a high level of homogeneity of feed mixing.
