STUDIES ABOUT THE AUTOMATED CONTROL OF STEAM TEMPERATURE IN THE FORMING MOLD OF THE COMPOUND FEED GRANULES IN VIEW OF ENVIRONMENTAL PROTECTION

The production process of compound feed is a complex one, with activities that involve releasing some dust particles into the atmosphere by grinding cereals and using some steam jets at very high temperatures. For this reason, in compound feed factories must be designed and used working installations with a high degree of mechanization, automation and computerization, with a high productivity level and low specific consumption, whose functioning to be verified by experimental modeling so as to offer a rigorous monitoring of noxes and of the dust eliminated in accordance with the European accepted norms.Thus, considering the complexity of the technological flow from a compound feed factory (CFF), in this article the thermal parameters of the work installation are being analyzed, in the homogenization and sterilization area of the compound feeds using steam jets at very high temperatures.In this article are presented the results of the experimental measurements carried out at the critical points of the technological flow for the production of different recipes of compound feed, that attest the advantage of using some automated working installations that function at the optimal designed parameters and at the same time fully comply with the EU requirements related to the protection of the surrounding environment
