Analytical solution of freeze-drying mathematical model based in Darcy’s law: application to an orange juice-based cake

Abstract: An analytical solution for moisture dynamic during freeze-drying based in non-ideal Darcy's law that resolves the singularity at zero time was deducted. The non-ideal Darcy's law is represented by a Darcy's pseudo permeability (K �) and a deviation index (n). The analytical solution must be complemented with a numerical solution of Fourier's equations for heat transfer in the two product zones. The model was fitted to experimental freeze-drying dynamics of an orange juice-based cake. The Darcy's pseudo permeab… Show more

“…We can use Darcy's law to define the seepage process. In the numerical simulation, a coupled model of Darcy's law and solid mechanics is chosen for the simulation analysis [28,29]. Through field analysis and construction scheme design, the simulation object is determined to be the process of coal seam grouting reinforcement.…”

“…En este sentido, para resolver la singularidad a tiempo cero, en esta parte del trabajo se pretende proponer una solución analítica para la ecuación de transferencia de humedad, basada en la ley de Darcy aplicada a la dinámica experimental de liofilización del zumo de naranja formulado con goma Arábiga y fibra de bambú, y conocer su capacidad de predicción para el mismo producto a diferentes temperaturas de liofilización. Los resultados de este trabajo se han publicado en la revista CyTA -Journal of Food (Uscanga-Ramos et al 2021).…”
