Optimization of the technology of fodder briquettes-licks with the use of a steam compression heat pump

In conditions of industrial maintenance of animals, their health is noticeably weakening, in the majority of the body, profound metabolic disorders are noted, and productivity is reduced. In such conditions it is necessary to use feed additives in the form of briquettes-licks, able to compensate for the lack of micro and macro elements, vitamins and many other substances. Intensification of feed production through the use of new advanced technologies allows to improve the quality of products and reduce losses in its production. The technologies used for briquettes-licks and equipment for their production do not always allow to provide high quality products and achieve the necessary effect when fed. In addition, they are energy-intensive, do not imply the use of secondary energy carriers. Therefore, the creation of a functional product, combining a complex of substances necessary for animal feeding, and the development of an energy-efficient method for its production is topical. The proposed technology makes it possible to obtain feed briquettes with high homogeneity and a specified content of biologically active substances, to ensure a longer-term preservation of the products. The developed line provides for the maximum rapid cooling of the finished product and a reduction in the specific energy consumption for its production as a result of the heat of spent coolants. The high-quality licks produced were homogeneous in their composition, resistant to unfavorable conditions. They are characterized by a higher stability of structural and mechanical properties and stability of storage quality for a long time: after twelve months, the technological properties of the products have not changed, signs of damage associated with increased humidity of the environment have not been noted. On the surface of briquettes, signs of development of microflora were not observed. The values of microbiological quality indicators were within acceptable limits. The development of energy-efficient method of its production is relevant. The proposed technology allows to obtain feed pellets with high uniformity and specify the content of biologically active substances, provide a long-term preservation products. It gives the possibility of issuing briquettes with high quality. In the developed line provides the most rapid cooling of the finished product and the reduction of specific energy consumption for its production as a result of the use of waste heat coolant. High licks were homogeneous resistant to adverse conditions and maintain the structural and mechanical properties and quality for a long time.If stored for twelve months technological properties of the product have not changed, deterioration of symptoms associated with high ambient humidity, it is noted. On the surface of briquettes signs of microflora is not observed. Values of microbiological quality parameters were within acceptable limits.
