The coffee-ring effect for particle deposition near the three-phase line after drying a pinned sessile colloidal droplet has been suppressed or attenuated in many recent studies. However, there have been few attempts to simulate the mitigation of the effect in the presence of strong particle-particle attraction forces. We develop a three-dimensional stochastic model to investigate the drying pr...

In this paper a mathematical model for the soda ash drying process in pneumatic dryer was presented. The presents macroscopic aspect of process, two-phase, gas-solid system. is based on mass and heat transfer between gas phase particle, movement air particles through system, geometric characteristics system (fan, heater, dryer, cyclone). effects parameters, such as airflow, inlet temperature, r...

Superheated steam drying technique has been known for a long time, but its application to food drying has received little attention. In this work, superheated steam was applied to dry fresh parsley (Petroselinum Cripsum). A mathematical model to simulate this drying process was developed by using mass and energy conservation equations for solid and steam phases. The resulting partial differenti...
