Determination of the average coefficient of internal moisture transfer during the drying of a thin bed of potato slices
TLDR
In this article, the authors developed a calculation pattern stemming from the two main equations expressing the drying process: the heat equation in a porous medium applied to the product arranged in a bed of particles and the equation of the drying rate using the Combes transfer pattern.About:

Design and simulation of a solar dryer for agriculture products
Lyes Bennamoun,Azeddine Belhamri +1 more
TL;DR: In this paper, a simple efficient and inexpensive solar batch dryer for agriculture products was used. But the drying is affected by the surface of the collector, the air temperature and the product characteristics.

Estimation of effective moisture diffusivity of okra for microwave drying
TL;DR: In this paper, the effect of microwave output power and sample amount on effective moisture diffusivity were investigated using microwave drying technique on round okra (Hibiscus esculentus L.).
Performance Evaluation of a Mixed-Mode Solar Dryer
TL;DR: In this paper, a mixed-mode solar dryer for food preservation is presented, where the heated air from a separate solar collector is passed through a grain bed, and at the same time, the drying cabinet absorbs solar energy directly through the transparent walls and roof.

Numerical simulation of drying under variable external conditions: Application to solar drying of seedless grapes
Lyes Bennamoun,Azeddine Belhamri +1 more
TL;DR: In this article, the authors studied the drying kinetic behavior with respect to the variation of the external conditions and used diffusion model based on Fick's law to calculate the coefficient of diffusion.

Changes in structure, density and porosity of potato during dehydration
N. Wang,J.G. Brennan +1 more
TL;DR: In this paper, the degree of shrinkage of potato during low-temperature drying is greater than at high temperature drying, and a model was developed to represent the relationship between the density and moisture content.
Journal ArticleDOI
Shrinkage during drying of foodstuffs
TL;DR: Experimental shrinkage data as a function of water content for particles of potatoes, apples and carrots of different geometry and under various drying conditions are presented in this paper, where a simple model in which volumetric ratio is represented by one or two line segments is developed.

The determination of sorption isotherm and the isosteric heats of sorption for potatoes
C.P. McLaughlin,T.R.A. Magee +1 more
TL;DR: Sorption isotherms were determined for potatoes at three different temperatures (30, 45 and 60 °C) using a standard gravimetric method using a Clausius-Clapeyron equation as mentioned in this paper.

A Mathematical Model of Simultaneous Heat and Moisture Transfer during Drying of Potato
N. Wang,J.G. Brennan +1 more
TL;DR: In this article, a mathematical model of simultaneous heat and moisture transfer is proposed for the prediction of moisture and temperature distributions during drying in a slab-shaped solid, taking into account the effect of moisture-solid interaction at the drying surface by means of sorption isotherms of food.

Physical characteristics of dehydrated potatoes — Part II
W.A.M. McMinn,T.R.A. Magee +1 more
TL;DR: In this article, the degradation of the physical attributes of a convective drying system was evaluated on the basis of rehydration characteristics, namely the coefficient of re-hydration and rehydrations ratio, with the extent of cellular and structural disruption determining the rehydrational capacity.
