Abstract. The article presents the results of studies confirming the law of the gamma distribution of microcapillaries in the structure of materials having a stochastic structure, for example, natural skins. The relative humidity of the latter depends on the mass of moisture collected by the microcapillaries, with heat and mass transfer under vacuum conditions. Numerical values of relative humidity in this case may differ from those recommended by footwear manufacturing technologies and should be considered as an integral part of the phenomenon of high-intensity heat and mass transfer under vacuum conditions and be determined by the proposed models.

Abstract. Objective of this research is creation of an algorithm of a control system of the modes of the intensive hygrothermal influence (IGI) in the conditions of a vacuum when performing the corresponding operations: moistening; the subsequent, if necessary, cyclic drying from within preparation of top of footwear; damp thermal treatment on universal installation with adjustable parameters of a working environment. For assessment of quality of the intensified hygrothermal impact on preparations of top of footwear the integrated criteria of efficiency of processes were used. Ensuring automatic control of parameters of processes of IGV on preparations of top of footwear in universal vacuum installation will allow to control quality of preparations upon transition from performance of one operation to another according to standard manufacturing techniques of footwear.

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. 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.
