In the development of sericulture, enhancing energy efficiency and the ecological safety of the process at all stages of mulberry silkworm cocoon processing is of significant importance. The effective use of solar energy in thermal treatment processes is one of the promising approaches to reducing energy consumption. This article details the development of a simulation model for the thermal processes occurring within the chamber of an electrotechnical device designed for the heat treatment of mulberry silkworm cocoons, utilizing the Simulink package in Matlab. The parameter values for each block and element comprising the model were determined. This model was then used to investigate the thermal processes within the device's chamber and to assess the influence of various factors on the temperature regime of the cocoons. During the thermal processing of cocoons, the time-dependent changes in the energy consumption indicators of the electrical equipment were determined and analyzed. An analysis of the change in electricity consumption over time enabled an assessment of the device's energy efficiency.
