  Article:   AN INTERPRETATION OF SOLID-LIQUID EXTRACTION USING THE GENERAL DIMENSIONAL METHOD.

  Abstract:   The solid-liquid extraction is a very common method for recovery of bioactive compounds in both laboratory and large scale. Determining the conditions of operation is based for the most part on a researcher’s practical experience. For scaling up to industrial conditions mathematical models or criteria equations are necessary. The paper presents the application of a general dimensional method to determine the parameters which influence the process and their respective degrees of impact. The parameters considered are: time, the equivalent diameter, the diffusion coefficient, density, dynamic viscosity, Earth’s gravity, the interfacial force, the power dissipated into the process and linear velocity. The mathematical relation between the parameters in different conditions and the interpretation of this result is presented.

Keywords: solid-liquid extraction, general dimensional method, mathematical model of solid-liquid extraction, criteria equation of solid-liquid extraction.
