Effect of the Drying Temperature of the Drum on Moisture Content of Cotton Components

Abstract

The article covers the drying process of cotton in the drum, and it has been shown that the unevenness of the initial moisture distribution in cotton is the main factor affecting the uneven drying of the fiber seed. The effect of drying temperature on moisture content of cotton, fiber and seed has been determined and their regression equations have been derived. The initial moisture differences of the cotton components are significantly larger, and it has been found that there is very little possibility to minimize them by changing the drying temperature. The amount of moisture released from cotton, seed and fiber at different drying temperatures has been determined and analyzed.

The average drying rates of the cotton components and the amount of moisture release have been determined, and it has been established that the effect of drying temperature and the average drying rate of cotton and seed were almost the same.

The drying rate of fiber at drying temperature up to 160 °C is lower than the drying rate of cotton and seed, and the reasons for this have been shown. The formula for determining seed moisture has been given. It has been recommended to obtain fiber and fiber moisture as indicators characterizing the state of moisture in technological processes of cotton processing.
