The problem to justify the influence of low-frequency mechanical vibrations on external mass transfer under the conditions of vibroextraction from plant raw materials and establish the regularities of its change depending of the mode parameters of the process was stated. Tim intensive renewal of the contact surface of phases in vibroextractors was achieved due to the mode parameters of the process (frequency and anqjlitude of vibrations of the vibrotransporting system). The established functional dependence of saturation of the extract by extractive substances with time on the volume mass-transfer coefficient will enable us to determine the minimum time for which the system achieves die equilibrium state of not only extraction processes, but also of the processes that are accompanied by mass exchange in apparatuses with mixing devices. The conclusions and results of the mathematical modeling under the conditions of vibroextraction agree with the results of die experiments.
