Method for The Primary Processing of Silkworm Cocoons (Bombyx Mori)

Abstract

The article discusses the results of an experimental study of the process of primary processing of silkworm cocoons (Bombyx mori). During the study, the possibilities of the primary processing of silkworm cocoons using elastic waves with infrared radiation were examined. The Tashkent State Technical University has developed a mechanism for generating low-frequency oscillations due to an electromechanical drive to pallets. In the laboratory of the department, a full-scale test was carried out for the primary processing of silkworm cocoons (Bombyx mori). Studies were carried out to determine the parameters as temperature and time of primary processing of silkworm cocoons in 5 times repetition. The results of the experiments are the primary processing of live cocoons (Bombyx mori) in the amount of one hundred pieces with infrared rays, the effects of vibration and elastic waves (the distance between the tube distributing infrared rays and raw materials is 10 cm, the duration of the process is 5 minutes). The study revealed that, as silkworm cocoons processed in the temperature range at 65-70 0С using vibration waves were moderate for 3-5 minutes and for 10 days at a temperature of 38-42 0С the cocoons continued to dry to 10-12% of the cane humidity. The use of elastic waves in the processing of cocoons proceeded 5-10% lower relative to the processing using vibratory waves. The obtained results, the experiments confirm that when applying vibration and IR radiation accelerates the process of primary processing of silkworm cocoons. The study found the optimum temperature and time for the primary processing of silkworm cocoons. Due to briefly temporary processing, the final product is improved.
