Abstract

We studied the kinetic regularities of filtration drying of corn alcohol distillery stillage. The kinetic curves characterizing the process of filtration drying of corn alcohol distillery stillage at different parameters of the stationary layer of the studied material and thermal agent were obtained: at different heights of the wet material, and at different temperatures of the thermal agent and the velocity of its movement through the stationary layer. The calculated dependences for determining the intensity of the filtration drying process in two conditional drying periods were proposed. The equations for the calculation of drying time separately for each conditional drying period were given. The maximum value of the relative error is 19.42%, while the average relative error is 5.37%, which is an acceptable deviation in practical calculations of experimental and industrial drying installations.
