Abstract
To ensure uniform temperature in the infrared vibratory drying unit and to preserve the quality of the final product during the initial processing of silkworm cocoons, the temperature field was studied using a thermal imager. Using a thermal imager, you can measure the temperature in contactless and remote processes. At the same time, you can obtain temperature information from several points. The thermal imager measures infrared radiation in the long-wavelength range within the field of view and automatically detects cold and hot spots. Based on this, the temperature of the measured object is calculated. The thermal image appears on the thermal imager screen and the obtained image results are processed on a computer.
Highlights
The program for the development of silkworm cultivation and processing of silkworm cocoons of the Republic of Uzbekistan in recent years provides conditions for the restoration and development of the silkworm industry, providing silkworms with high-quality local croutons, increasing the volume of production of silkworm cocoons, increasing the silkworm's feed base and providing silkprocessing enterprises with high-quality raw materials.Cocoons produced by silkworm caterpillars are one type of natural structure and polymer composite materials that have excellent mechanical properties
P.Wu et al [4] showed that the main goal of drying silkworm cocoons is to kill pupae and reduce the potentially hazardous moisture content, which allows cocoons to be stored for up to a year in appropriate conditions
On the basis of the obtained theoretical results, an experimental infrared vibration unit was developed at the Tashkent State Technical University, which allows carrying out the process of carrot and drying of the optimal parameters of the processed silkworm cocoons (Fig. 2)
Summary
The program for the development of silkworm cultivation and processing of silkworm cocoons of the Republic of Uzbekistan in recent years provides conditions for the restoration and development of the silkworm industry, providing silkworms with high-quality local croutons, increasing the volume of production of silkworm cocoons, increasing the silkworm's feed base and providing silkprocessing enterprises with high-quality raw materials. For the death of pupae, drying of cocoons is used without allowing them to turn into a moth (butterfly), otherwise it will leave the cocoon, breaking through the shell, making it useless. P.Wu et al [4] showed that the main goal of drying silkworm cocoons is to kill pupae and reduce the potentially hazardous moisture content, which allows cocoons to be stored for up to a year in appropriate conditions. Silkworm cocoons must be dried immediately after harvest due to the possibility of the appearance of moths from the pupae that they contain, and can spoil an important feature of the cocoons from the inside, which leads to the rolling of raw materials. On the basis of the obtained theoretical results, an experimental infrared vibration unit was developed at the Tashkent State Technical University, which allows carrying out the process of carrot and drying of the optimal parameters of the processed silkworm cocoons (Fig. 2)
