New mathematical model of vegetable oil extraction in an industrial extractor is proposed to predict the concentration distributions in percolation sections and in the outlets. The model incorporates: counter-current crossed flows of the raw material and the miscela, mass transfer between the raw material and the miscela, diffusion in the entire extraction field, miscela transport between the extraction sections, influence of loading and drainage zones.. The model is composed of sub-models for the extraction sections, trays, drainage and loading zones. The sub-models are coupled each other by means of the boundary conditions, and reflect the particularities of counter-current crossed flows. The calculation algorithm is based on the method of lines
