Irrigation and Melioration

Abstract

This article describes the technological features of the reduction of technical varieties of cotton. Requirements for technical seeds in the processing of raw cotton are technical specifications and quality indicators. Seeds of technical cotton with quality indicators and adapted technical seeds must meet the requirements of technical conditions. The technical need for coated seeds should correspond to technical characteristics, such as reducing production costs, reducing moisture, long-term storage, improving quality, thermal conductivity, aerodynamic resistance, and heat resistance. From the point of view of heat treatment of seeds, parameters taking into account their thermophysical properties should be used to justify the process of reducing the moisture content of technical seeds and the parameters of electric heating equipment that implements it. The thermal conductivity of cotton seeds is 0.120-0.140 W/(moC), which is 2-3 times higher than the thermal conductivity of the seed layer. In turn, the thermal conductivity of the seed layer is 0.24-042 W/(moC) degree depends on the humidity and temperature of the seeds. The propagation velocity of the heat wave in the seed layer is about 0.2 mm/s
