Overview of feed granulation technology and technical means for its implementation

Abstract

The choice of methods for storing feed and the processes of their processing in farms is the most important task for maintaining the qualitative composition of feed components, which determined the relevance of our work. In this work, we consider the technology of feed granulation, its features, as well as the technical means used for this process. Two granulation technologies (wet and dry) were analyzed and the advantages and disadvantages of each were identified. Quantitative and qualitative characteristics of feed before and after granulation are considered. The positive effect of granular feed on the breakdown of protein in young cattle, a high digestibility, and, consequently, an increase in the productivity of animals is observed. It should be noted that the granulation of waste processing industry can extend their shelf life and increase overall nutritional value. In addition, processed granular waste in combination with other feeds can replace up to 50.0% of grain in the diets of farm animals. The paper gives a brief analysis of the main manufacturers of industrial granularizers with a ring matrix, as well as the technical characteristics of their products. This analysis confirms the popularity of feed granulation in the Russian Federation, which is confirmed by a wide range of manufactured equipment of various capacities.
