Drying of post-alcohol grains by the combined method in order to obtain protein feed for farm animals and poultry

Abstract

The work shows the feasibility of processing after alcohol bards in feed for farm animals and poultry. The kinetic laws of drying after a grain of alcohol are given by the combined method, which includes combinations of the convective and microwave methods of drying. By comparing the kinetic laws of the drying process by the convective method and the combined method, the advantages of the combined drying method are shown. Based on the above experimental data on the kinetics of the drying process and preliminary calculations, the duration of heat treatment with the combined method is reduced by 3040%; in terms of energy costs, the convective drying method is 15% higher than the combined drying method. Based on the above studies, the article concluded that the combined drying method is more effective than the convective drying method.
