Abstract
The article deals with issues related the use of rotary pulsating apparatus as dispersants, in the processing of liquid dispersions containing dietary fiber. Considerable intensification of the milling process can be achieved by conducting the process in a liquid medium, the process efficiency is improved due to the action of water due to mechanical activation disperse systems to be treated. An approach to determining the energy balance of the components in terms of physical size, easily accessible for direct measurements without the use of specialized tools and methods and binding costs of available capacity on the dispersion of the characteristics of the process - the multiplicity of processing and degree of grinding object of study is a model mixture is a suspension of the pulp of carrots water in a concentration of 5 mass%. The duration of exposure to the treated product is characterized by the multiplicity of treatment, depending on which determines the amount of power consumed by the device when idling and in the processing of model mixture. Determined experimentally, depending on the frequency of spraying, the following quantities characterizing the dispersion process: the temperature of the mixture model, the efficiency of the grinding process, the degree of crushing. Presented in the integral characteristic relates the specific energy consumption for the dispersion process with a degree of grinding and allows comparative analysis with other designs of dispersants. It is found that the dispersion process effectively proceeds up to a value of the multiplicity of processing, when reaching a number of useful consumed power remains practically constant, which does not lead to an increase of fineness, consumption unit power consumed only to move the product to be treated, and further increase the degree of crushing can be achieved by increase the speed of the rotor. On the basis of analysis of experimental data generated for ways to reduce dispersion of the expenditure of energy.
