Research of the influence of mulberry silkworm cocoon structure on drying kinetics

Abstract

This article presents an experiment on drying mulberry silkworm type 3 cocoons using universal infra-red drying equipment. Three types of cocoons, Bombyx mori, Antheraea pernyi and Antheraea mylitta, were used as an object of research. A universal (convection) drying equipment with an infrared heat source was used, which allows a fairly wide variation of the operation and load parameters (chamber temperature °C and air speed up to ±0 °C). t1 = 70 °C, air velocity up to ω = 0,7 m/sec and the drying load volume Pc = 0,5 kg/m2. The parameters that ensure the maximum intensity of the drying process while maintaining the quality properties are: coolant temperature in drying equipment within t1 = 65 …75 °C and the air velocity, which gives the best performance with the lowest possible losses in the ranges of ω = 0,6 − 0,7 m/sec.

Localization conditions of apometaterrigenous non-carbon the Sarykul deposit of the Karatyubinsky ore district in Uzbekistan

“…The paper aims to substantiate the conditions of localization of non-carbon apometaterrigenous tungsten mineralization at the Sarykul deposit and determine the prospects of the Karatyubinsky ore district for unconventional apometaterrigenous tungsten mineralization. The research objects are mineralized zones of the Sarykul deposit in the Karatyubinsky ore district [20][21][22][23]. The research methods include a complex of field observations (geological search routes; geological documentation and sampling; compilation of lithological, mineralogical, and structural sections, etc.…”

A Comparative Study of Drying of Muga Cocoons using Convection and Infra-red Heating Method

“…Drying cocoons using IR treatment would determine an optimum mode for energy saving and control the technological processes of the drying equipment for producing high-quality and environment-friendly products (Zulpanov et al, 2022).…”
