METHOD FOR THERMAL DISINFECTING OF COMBINED BULK FEED Russian patent published in 2005 - IPC

FIELD: agriculture and feed production, in particular, preparing of bulk feeds in animal houses and feed producing enterprises.

SUBSTANCE: method involves heating, steaming, drying, cooling and homogenizing bulk feeds. Disinfecting procedure is carried out in two thermal processing steps: first step involving high temperature processing and second step involving low temperature processing. Each step is combined with process of mixing combined feed components in gas-mechanical fluidized bed. At first step, thermally stable components are initially subjected to heating to temperature of 85-110°C and to wetting with steam, followed by slight drying to initial moisture content with hot air, and at second step hot mass is cooled with air to ambient medium temperature. In the process of cooling, when temperature reaches 50°C, thermolabile biologically active components, such as vitamins and enzymes, are added, said components being thoroughly mixed with remaining part of combined feed, with cooling procedure being continued.

EFFECT: increased efficiency of process and reduced costs for effectuating thermal disinfecting of combined bulk feeds.
