It is known that in the process of crystal formation in vacuum apparatus grocery sugar factory Office crystalline white sugar covered by a film of such qualitative indicators affecting commodity sugar substances as liming and coloring substances. So at a sugar factory, one of the important operations process flow for obtaining sugar high product standards is it washing. At the same time, in implementing this process, use water in two phase conditions-a liquid or vapor. Because from an economic point of view, this procedure is quite expensive, in production environments to reduce labor and material costs, are resorting to various ways to less expensive equipment and process technology washing of granulated sugar. Moreover, although it is more often used in the production of water, according to experts, the process of washing by centrifuging massecuite layer of crystalline white sugar economically feasible to conduct, using no water, and water vapor. In particular, if you rinse the sugar vapor due to condensation heat allocated about half of a film on experiencing enormous heating in several tens of degrees Celsius, which reduces the viscosity and facilitate its films Office in the form of liquid. However, it should be noted and clearly insufficient elaboration, with the purpose of forecasting of the washing of the ferry, as low density liquids, sugar-sand theoretical base for its convenience. Therefore, in the work, analyzing process flow a couple of washings quantitatively the compacted layer of porous systems as granulated sugar, use a porous system hydrodynamics position when for a vaporous fluid through a layer of granulated sugar simulate fluid flow in an isolated capillary tube. That allowed when calculating the effectiveness of steam wash a layer of granulated sugar to implement based on the mathematical apparatus of the theory of convection diffusion corresponding numerical experiment and offer it for engineering calculation of the process.
