Press granulators, technical features, influence of granulation on qualitative characteristics of feed

An important task for any farming enterprise producing animal products is to provide feed with high nutritional value for the animals. At the same time in addition to growing and preserving feed of their own production, farms purchase, including food processing products: brewing waste, beetroot pulp, brewer’s grains, etc. These wastes are usually delivered in liquid form and have a low nutritional value and shelf life, as well as a high specific cost of transportation. One of the solutions to this problem is the use of granulation technology. The main types of press granulators, their design features and operating principles, as well as the materials of scientific researches aimed at studying the properties of granulated feed have been described in the article. Thus, according to the materials studied, the use of press granulators in the process of processing food waste allows to achieve an increase in their nutritional value and shelf life of feed. Analysis of the use of granulated feed in the diet of animals has shown their better digestibility compared to feed presented in crumbled form, which contributed to an increase in productivity in animals. Thus, we can conclude that the use of press granulators in the process of feed preparation of various designs is a promising direction of production. At the same time, the choice of the granulator should be based on its technical features and performance. So, for a small agricultural enterprise, fl at-matrix granulators with a capacity of up to 1000 kg/h are suitable.
