In the numerical modelling of the vacuum contact drying of disordered porous media, the explicit MacCormack finite differences method was employed for solving both hyperbolic and parabolic moving boundary problems. A comparison of the parabolic and hyperbolic solutions, analysis of relaxation time of heat flux [tau q] influence and experimental verification of the simulated results were presented. Experimental verification was performed for vacuum contact drying of the following biomaterials: fodder yeast and lactose.

W modelowaniu matematycznym kontaktowego suszenia próżniowego materiałów porowatych o nieuporządkowanej strukturze zaproponowano metodę różnic skończonych MacCormacka do rozwiązywania parabolicznych i hiperbolicznych modeli numerycznych problemów ruchomej granicy. Przedstawiono porównanie rozwiązań, analizę wpływu czasu relaksacji strumienia ciepła [tau q] i weryfikację eksperymentalną. Weryfikację doświadczalną przeprowadzono dla kontaktowego suszenia próżniowego produktów biotechnologii: drożdży paszowych i laktozy.
