Studying the kinetic regularities of the drying process after the alcoholic bards for the development of the technology for producing protein food for agricultural animals and poultry

Abstract

For feed of farm animals and poultry, protein-containing additives derived from the waste of the alcohol industry enterprises have great prospects. The paper shows the feasibility of processing distillery stillage into protein feed for farm animals and poultry. The construction of the kinetic laws of the drying process allows you to determine the main technological parameters of drying; optimal options for the drying process; the possibility of hydro-mechanical separation of moisture; choice of drying method; installation design for the process and its calculation. The purpose of this work was to determine the kinetic patterns of the drying process of distillery stillage, which are necessary for the further development of the technology for producing a dry product. From the above kinetic dependences, we can conclude that the distillery bard refers to capillary-porous bodies with a small specific surface area; the duration of the drying process is significantly reduced by increasing the speed of the material blowing with a drying agent, this is especially noticeable in the first drying period, when free moisture is removed. The experimental data obtained will make it possible to use them in the future to select the optimal drying regimes for distillery stillage.
