TLDR
In this paper, the theoretical foundation for the concept of the characteristic drying curve is examined by considering the drying out of a porous, non-hygroscopic slab of infinite extent.About:

The assessment of a characteristic drying curve for milk powder for use in computational fluid dynamics modelling
TL;DR: In this paper, a linear falling-rate curve is used to estimate the drying times of milk powder in spray dryers. But this was only for particle sizes of greater than 2mm.

Convective drying of Spirulina in thin layer
Hélène Desmorieux,Nadège Decaen +1 more
TL;DR: In this paper, a simple Henderson model is proposed to represent the isotherm of spirulina by convection, which is characterized by the kinetics experimental drying in order to study the influences of temperature and air velocity.

What is important in the simulation of spray dryer performance and how do current CFD models perform
David Fletcher,Baoyu Guo,Dalton J. E. Harvie,Timothy A. G. Langrish,J. J. Nijdam,Jennifer Williams +5 more
TL;DR: In this article, a summary of many years work performed at Sydney University investigating the fundamental flow behaviour in dryers and their modelling using a commercial CFD code is presented, where the key point to emerge is the need to perform three-dimensional, transient calculations and to include hindered drying and wall interaction models if important issues of flow stability and wall deposition are to be studied.

A review of process simulations and the use of additives in spray drying
S. Wang,Timothy A. G. Langrish +1 more
TL;DR: In this paper, casein has been examined and found to coat spray-dried particles at 1/w/w, significantly lower than other additives, such as maltodextrin, which commonly make up between 10/w /w% and 20/w % of the total solids.
Journal ArticleDOI
Effect of drying on biofilter performance: modeling and experimental approach.
TL;DR: A dynamic one-dimensional model was developed to describe drying and its effect on bio filter performance and predicts water evaporation from the packing material as a consequence of metabolic heat generation and variations of the relative humidity of the inlet air stream, and the resulting decrease in biofilter performance.

Mass-transfer operations
TL;DR: In this article, the Mass Transfer Coefficients for Moleuclar Diffusion in Fluids and Interphase Mass Transfer in Solid-Fluid Operations are presented. But they do not consider the effect of ion exchange in solids.

On the mechanism of drying of granular beds
Mutsumi Suzuki,Siro Maeda +1 more
TL;DR: In this article, the authors defined the ratio of the rate of lateral movement of fluid to the flow rate in the interior of the bed as a function of the velocity of fluid displacement normal to the wall to the normal flow rate.

Equilibrium heat and moisture transfer in air flow through grain
TL;DR: In this article, the basic equations describing coupled equilibrium heat and mass exchange between a porous medium and a permeating fluid mixture have been derived by Banks 1 in terms of characteristic potentials.
