OXYGEN SORPTION IN COMBINED FEEDS DURING STORAGE

Abstract

One of the primary vectors for the development of enterprises in the compound feed industry is to solve urgent tasks related to improving technologies and methods aimed at optimising the use of raw materials, improving their quality, increasing yields and expanding the range of finished products suitable for long-term storage. The quality of compound feed during storage largely depends on its physical properties, chemical composition, characteristics of its components, their uniform distribution in the mixture, the presence of antioxidants, production technology, and storage conditions.
At the same time, the complex influence of these factors on the duration of storage has not yet been sufficiently studied and systematised. It is important to establish the optimal storage period, since the economic losses of feed components when this period is exceeded are unjustified. In view of this, it is becoming increasingly important to study the interrelated processes of mixing and storage, which will allow determining the patterns of changes in the quality of compound feed at minimum cost. As part of this study, it is necessary to assess the impact of mixture homogeneity on the storage efficiency of bulk feed, which is of significant scientific and technical importance. There is an urgent need to develop a number of scientific approaches, including:
- establishing patterns of changes in the qualitative characteristics of feed mixtures depending on chemical compounds and physical properties;
- determining an indicator for assessing the uniformity of feed component distribution in the mixture;
- studying the formation of homogeneous mixtures in relation to the physical properties of components, their composition, mixing duration, and parameters of the continuous mixing process;
- developing a methodology for determining feed component losses during storage;
- justification and selection of a comprehensive criterion for assessing the effectiveness of compound feed storage, taking into account the total cost of compensation for losses.
The article proposes a generalised model that effectively describes the process of oxygen sorption as a function of two variables.
