Search for ways to increase yield and improve product quality in the process of saw ginning

Abstract

This article presents the results of research on increasing fiber yield and improving product quality by using a new design of the vas deferens from the working chamber. It has been experimentally established that the most rational in terms of yield and quality of fiber, seeds and gin productivity is the position of the seed comb when the axes of its pegs are directed 5-10 degrees above the axis of the saw cylinder. The smallest value of complete hairiness of seeds after gin was obtained when installing a lamellar seed comb. Its average value was 13.8%. At the same time, the fiber yield was maximum - 34.66%, and the highest productivity - 8.5 kg of fiber per saw per hour. The influence of the distance between the ends of the seed comb pegs and grates at their values of 10, 20, 30 mm on the ginning indices was investigated. A distance of 20 mm is recognized as optimal taking into account all indicators - fiber yield, complete pubescence, productivity, quality of fiber and seeds. An experimental working chamber equipped with lamellar combs was made. It has been tested in the production conditions of a pilot cotton mill.
