Selection Of Optimal Parameters For Primary Processing Of Mulle Cocoons By A Combined (IR + US) Method

This scientific study is devoted to an experimental investigation of the effectiveness of a combined ultrasonic and infrared treatment method for reviving silkworm pupae. The study assessed the effects of treatment time, temperature, and ultrasound frequency on the degree of pupal necrosis. Experiments were conducted at a temperature of 60-80°C, an ultrasound frequency of 20-40 kHz, and a treatment time of 180-480 seconds. The results showed that the degree of necrosis consistently increased with increasing treatment time and ultrasound frequency. High efficiency was found to be achieved even at low temperatures, especially at an ultrasound frequency of 40 kHz. Based on the experimental results, optimal treatment parameters were proposed for high-quality degreasing of silkworm cocoons and minimizing the negative impact on cocoon quality. The obtained results have practical implications for the development of energy-saving and modern technological solutions in sericulture.
