Modeling of capillary-sorption process steam condensation in the system of microcapillaries of grain shells

The aim of this study is to simulate the capillary-sorption process of steam condensation in the system of microcapillaries of grain shells [1]. Modeling of the processes of intensive moisture transfer during drying of a number of materials was considered in [2,3]. In order to significantly reduce the time of moistening, moisture transfer by effusion is considered in the form of steam produced at low pressure (vacuum) with its further guaranteed condensation in micro-cavities (microcapillaries) of a porous shell of grain [4]. Study of intensity of moisture transport in accordance with the changes in concentrations of vapour along the length of the capillary in a vacuum proved the possibility of intensifying the process of moistening the grain before grinding. The obtained mathematical model will allow to calculate the values of the theoretical weight gain of moisture in microcapillaries depending on the parameters and the time of vacuum-sorption moisture

Ways of intensification of the process of moistening the grain before grinding

The aim of this study is substantiation of ways of reducing the time required to process pre-wetting the grain before peeling, flattening, grinding [1]. A method of moistening the grain before grinding with preevacuation of its interior microvoids through the porous shell provides moisture transfer in the liquid phase. This moisture transfer requires the subsequent application of excess pressure to the penetration of moisture to the core of the grain and subsequent long-term otvalivayas grain. To significantly reduce the time of wetting is proposed to use a moisture transfer with effusion in the form of steam produced at low pressure (vacuum), then the guaranteed condensation in micropolitan porous shell of the grain.
