ModChenMSI {PUPMSI}

Modified Chen Moisture Sorption Isotherm

Description

Modified Chen is 2-parameter model related to the drying principle. It is restricted to situations where diffusion is the primary mode of mass transport and is focused on the steady state of the drying equation.

Usage

ModChenMSI(WaterAct, AdsorpM, DesorpM)

Arguments

WaterAct

the numerical value of Water Activity, which ranges from 0 to 1.

AdsorpM

the numerical value of the Moisture content of the Adsorption curve, which ranges from 0 to 1.

DesorpM

the numerical value of the Moisture content of the Desorption curve, which ranges from 0 to 1.

Value

the nonlinear regression, parameters, and graphical visualization for the Modified Chen Moisture Sorption Isotherm model.
