PROTECTING THE ENVIRONMENT THROUGH AUTOMATED CONTROL OF WORK INSTALLATIONS IN COMPOUND FEED FACTORIES

The primary purpose pursued by any compound feed factory is that one to obtain and deliver to customers assortments of the finished product as nutritious as possible and at the lowest possible production costs. But, at the same time, compound feed factories must fulfill the environmental protection standards imposed by the European Union regarding the amounts of dust and other polluting substances released into the atmosphere, as well as a limitation of the temperatures released by the working installations during the production process. In order to realize these environmental protection requirements, the compound feed factories must be equipped with modern and high-performance working equipment, which ensures a permanent automated and computerized control of the optimal operating parameters during the entire technological process. In this paper are presented the stages of the production process of compound feed, with accent on the analysis of those critical points on the technological flow route where very high temperatures are released or different amounts of dust are eliminated into the atmosphere. In order to highlight the reliability of automated and computerized control equipment of work installations, experimental measurements of the working technological parameters were carried out for two distinct assortments of combined feeds, depending on the utility of each recipe: for feeding broilers and for feeding cattle.
