Building Mathematical Models Drying Processes Of Raw Cotton Based On Heat And Mass Transfer Equations

Аннотация

The paper considers the construction of a mathematical description of the drying process of raw cotton, taking into account the thermophysical and mass transfer properties of the components of raw cotton. To determine the temperature changes of fiber, raw cotton seeds, the application of the Fourier law is proposed. The mathematical dependence of the change in humidity of the cotton fiber along the length of the drum is determined, and the rational values of the heat agent consumption in the process of drying the raw cotton are determined by experimental methods. he developed analysis of the mathematical model based on simulation showed the adequacy of the mathematical dependence of the temperature regime of the drying process of cotton with the consumption of heat agent. It was determined that, with increasing thermal conductivity in the considered limit, the pattern of change in seed moisture along the drum length will change significantly.
