DETERMINATION OF THE LIQUID MOVEMENT DYNAMICS IN THE DAIRY INDUSTRY TRANSPORTATION NETWORKS

Abstract

The physical essence of the influence of the hydraulic resistance and roughness vertexes in the adjoining layer with a large velocity gradient of detergents in the transport pipelines of raw materials on adhesion, which establishes dependence on the shape, velocity gradient and angle of roughness, application of mechanical forces, the degree of previous dispersion and physical and mechanical properties of the medium are considered. The nature of the contact interaction of a bacterial biofilm with a rough surface in the transport pipeline and the ways of degradation of the biofilm are determined. Violations of these mutual relations lead to efficient sanitary treatment, and, accordingly, the production of quality products and their appropriate shelf life. The contact area of the adhesive and the component forming work for overcoming the adhesion and deformation of the environment in determining the criteria influencing the process according to each particular period of the deformation stage are substantiated. The obtained data give an answer to a number of questions about the possibility of interaction between the surface and the environment, which establishes a real change in the adhesion contact in the pipeline. It was determined that in order to provide a variable area of actual contact, which contributes to better degradation of biofilms, and, accordingly, passing of a qualitative process of sanitary treatment of surfaces, the necessary condition is to maintain the velocity of movement of detergents to the corresponding technological parameters.
