Baigildeeva E.I., Ribin B.M., Rikunin S. N., Halitov R.A., Razumov E.U. HEATING OF CRUSHING WOOD IN THE MEDIUM OF SATURATED STEAM. There is a mathematical description of heatmasstransfer in the technological chips under its treatment by saturated steam in the hermetic apparatus. Here the differential equations which describe the changes of moisture and temperature in the wood fraction are given, and also the rate of movement of liquid phase in material. Supply of heat to the chips from the steam phase is fulfilled through the condensate film owing to molecular heat conductibility. And more, the movement of condensate in wood chips made humid and approximately dry zones of material. In humid zone the transfer of heat is fulfilled mainly owing to convection, and in proximately dry by mechanisms of heat and moisture conductivity. The experimental investigations confirm the results of calculations.
