Mathematical modelling of the drying process of sugar beet pulp with macro and microelement additions in order to improve the feed quality

Abstract

In this paper a kinetic study is performed on the drying process of beet pulp with additions of macro-elements (Ca2+, Mg 2+, PO42+) from hydrated lime, hydrated dolomite lime, phosphoric acid and microelements (Co2+, Zn 2+, Fe2+, Mn2+), with the purpose of obtaining premixes with substantially improved value for animal feed. The experimental measurements made served to elaborate the mathematical model by means of which the speed with which the drying process is carried out is described, thus being able to calculate the stationing time of the material in the dryer. The equations for calculating the stationary time of the material in the dryer can be used for designing dryers (sizing them).
