Study Of The Influence Of The Moisture Content Of Raw Cotton And Its Components On The Thermal Conductivity Coefficient

Abstract

The article studies thermal conductivity of raw cotton and its components. Raw cotton consisting of seeds and surrounded by fibers has higher thermal conductivity than fiber and less than lowered and bare seeds. Lower seeds consisting of smaller number and length of fibers have lower thermal conductivity than bare seeds and greater than raw cotton and fibers. Naked seeds that do not have fibers on their surface have a higher thermal conductivity than lowered seeds, raw cotton and fibers. The dependence of thermal conductivity of raw cotton and its components on the temperature at different humidity is obtained, which allows to carry out calculations by the equation of heat and mass transfer during drying of raw cotton.
