Drying Characteristics of a Porous Solid in Superheated Steam Drying

Modelling the Drying of Porous Coal Particles in Superheated Steam

The modelling and simulation of drying porous coal particles in superheated steam was investigated in this paper. Improved transport and kinetic parameters as well as particle shrinkage were considered in arriving at the results. The resulting partial differential equation describing the drying process was solved numerically using the finite element analysis in addition to other useful equation...

Using Superheated Steam in Drying and Sterilization

Botanicals are received in whole, non-sterile form. BI Nutraceuticals sterilizes, mills, and packages the ingredient in sturdy, safe containers before shipping to customers. Photo courtesy of BI Nutraceuticals Using Superheated Steam in Drying and Sterilization It seems counterintuitive to use water vapor in a process to remove water or to heat materials that can be damaged by moisture, but suc...

Superheated Steam Drying of Parsley: a Fixed Bed Model for Predicting Drying Performance

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...

Effect of colloidal Particles associated with the liquid bridge in sticking during drying in Superheated Steam

It is very important in the design of a drying system is to evaluate sticking behaviour of the materials goes under drying. A new approach to the sticking issue is applied in this study by carrying out a sticking test for the liquid associated with the materials under study. It was found that the liquid bridge is responsible of the initial sticking of the materials to the contact surface and th...
