ABSTRACT

The aim is to study convective drying of wool felt and plantar skin by regular regime. Basic theory postulates of regular regime in relation to the processes of drying moist materials are investigated.

Method of regular regime of heating of solids is used in the calculation of the drying process of moist materials and allows to calculate the kinetics of the process of integration operation without drying rate curve. All major drying kinetics parameters (duration of the drying temperature of the material in the second period and the intensity of heat transfer) can be found with a minimum number of experimental constants. This significantly reduces the time and amount of calculation work.

All the necessary data are presented and the dependence of the main drying parameters is calculate: the rate of heating, the values of the wet material and the rate of removal of moisture from the material; given function changes mean integral temperature and heat flux on the basis of the theory of regular regime.

The resulting equation for calculating the rate of heating and rate of moisture removal can be used for a group of moist materials. If you use the proposed methods, you can simplify the calculation of the parameters of drying and significantly reduce the number of experiments. Method regular thermal conditions can be used for the processing and analysis of the experimental data for drying of various materials with various methods for supplying energy.
