Sabadash S. Substantiation of energy-efficient drying process of DDGS

The thesis is devoted to the energy-efficient drying process of DDGS in pseudo liquefied layer of inert media. The scientific credence of feasibility of a fluidized bed dryer in an inert carrier for drying of DDGS usage is given. Optimal parameters for drying of DDGS in the fluidized bed of inert carrier are determined. Calculating dependences of the velocity of the fluidization from the beginning of drying till the removal of particles are determined. An empirical equation for calculating an inert carrier for drying of DDGS fluidized bed core diameter is obtained. Heat transfer equation for drying of DDGS on inert solids in the fluidized bed is obtained. A process flow scheme, construction of a drying of DDGS in a fluidized bed of inert carrie apparatus are developed. Economic efficiency of the introduction of this technology is calculated. The results of this research are implemented into the production and academic activity.
