The article is devoted to the process of preparing cocoons for unwinding, to soften sericin and weaken the forces of gluing and filling cocoons with water to make it heavier, according to the unwinding method used. The round steamer is designed to perform four main operations: soaking; heating; steaming; filling the internal volume of the cocoon with water.
When steaming, sericin softens excessively, partially dissolving, which reduces the yield of raw silk, and at the same time, the thread has a large number of defects; as well as reduced hardware performance. In the steaming process, it is important that the dissolution of sericin be minimal in order to maintain the adhesive ability of raw silk filaments, which decreases after hydrothermal treatment. For steaming cocoons, many different machines, devices and devices have been developed and used to carry out the process of steaming and unwinding cocoons.
At present, the following types of equipment manufactured in China, Uzbekistan, South Korea, and Japan are mainly installed in the Republic of Uzbekistan. The set of imported production equipment includes steaming machines of the KSS-207, FYIU2000NT models, working on the principle of processing cocoons in an environment with varying temperatures and equipped with an endless chain with 107 baskets. The productivity of the machine reaches 900-1200 kg of dry cocoons per shift, providing cocoons for 4 and 5 cocoon winders KSS-SR-120 and FYIU2000NT. However, in order to establish modes of steaming and filling cocoons for steamers, it is necessary to use small round steamers.
