- Abstract
The use of keratin-containing products in various industries, including agriculture, cosmetics, and biomedicine requires solving the urgent problem of improving the methods and means of hydrothermal hydrolysis of keratin waste. The purpose of this study is to examine the screw electromechanical hydrolyser to provide modes of efficient conversion of keratin waste into a useful product with added value. The study is based on the basic principles of electrodynamics, heat and mass transfer, mathematical modelling by the finite element method, and experimental verification of the multiphysical parameters of the electromechanical hydrolyser. The experimental model of the electromechanical hydrolyser was used to determine the optimal conditions for hydrothermal hydrolysis of keratin waste in terms of thermal conditions, raw material transportation, pressure, and magnetic field effects. After undergoing the processing, a bulk of brown feather flour was obtained, which had been hydrolysed and possessed a distinct odour. According to the size of the electromagnetic system of the experimental sample, a mathematical model for observing thermal and electromagnetic processes was built. The patterns of magnetic induction distribution were determined for the cross-section, axial distribution on the screw surface, and the upper faces of the screw winding in an electromechanical hydrolyser. Three-dimensional images of the heating of the screw and the screw electromechanical hydrolyser itself were obtained. By comparing the results of mathematical modelling and empirical studies, the adequacy of the mathematical model was confirmed. The findings of the study can be applied in the field of animal husbandry in the production of feed additives of increased digestibility for feeding agricultural animals and poultry.
