The low efficiency of the existing technologies for the extraction of desired components from vegetable raw materials with a high degree of milling is due to the imperfection of extraction equipment. Though the designs of modern periodic and continuous extractors are fairly diversified, there exist common disadvantages caused by the insignificant porosity of fine-fraction vegetable raw materials or the mass prepared from them for counterflow continuous extraction, their poor transportability, densification, and, as a result, the low permeability for the extractant. It has been established that vibratory extractors are most promising in this respect. In the present work, we present results of investigations of the intensifying action of low-frequency mechanical vibrations on the extraction process of desired components from vegetable raw materials under conditions of continuous vibration extraction. For industry, we propose a new design of a periodical and a continuous apparatus with vibratory mixing devices.

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.
