Improving the performance of equipment for countercurrent extraction on the basis of process simulation

The article discusses the possibility and efficiency of using discrete diffusion in extraction materials with an internal anisotropic structure comparison a continuous process. For this purpose, theoretical calculations were made experimental studies countercurrent pectin from Jerusalem artichoke carried out. To carry out simulation, equation for calculating coefficient adsorption isotherm during determined. Evaluation to obtain was by considering influence effect on rate resulting equations it possible analytically evaluate two-zone spherical particles multistage plant material. Having analytical data distribution extractable substance concentrations inner outer zones particle at different stages extraction, is calculate coefficients theoretically determine degree destruction cell walls structures extraction. developed technique, thanks description process, allows you select optimal conditions various animal raw materials.
