Abstract

The article presents the results of theoretical and experimental studies on drying of mulberry silkworm cocoons. Based on the analysis of drying efficiency and silk quality, the use of infrared radiation (IR) at a temperature of 70 °C was found to be optimal. The experimental data were tested on six mathematical models, among which the Midilli model most accurately described the drying process. The effective moisture diffusion coefficient was found to vary in the range of 1.847×10-⁹-4.339×10-⁹ m²/s, and the drying rate was found to be 0.32-0.79 kg of water/hour. IR radiation promotes accelerated evaporation of moisture by transferring heat inside the material and affecting the microstructure of the cocoons. This method ensures uniform heat distribution, high drying speed and reduced energy consumption. Optimal parameters of the drying process include a temperature of 70 °C and a duration of about 5 minutes, which allows to achieve energy savings and high quality of the final product.
