Theoretical and experimental study of primary cocoon processing

This study is aimed at studying the influence of basic parameters such as the power of ultrasonic waves, the power of infrared radiation, the drying temperature, the drying time and the drying kinetics of cocoons. We used two special methods to kill and dry the cocoons: infrared and combined (infrared-ultrasound). The results obtained indicate that the cocoon drying process as a whole can be controlled by the period of speed decline. With the infrared method, the drying speed increased with increasing temperature, while the power of infrared radiation did not have a strong effect on the killing process. Ultrasound has shown its positive potential in the primary cocoon processing.
