A model for the reciprocal conversion of malting barley Aw into moisture content (mc)

A model for the reciprocal conversion of malting barley Aw into moisture content (mc) was produced that enables to use observed mc recorded by NIR analysers in mathematical models.

A relative humidity sensor was tested in five storage bins equipped with temperature probes and filled with malting barley. Three bins were aerated with ambient air and two were not aerated. The moisture content (mc) of grain was measured and also calculated from automatically measured relative humidity and temperature, using the modified Chung-Pfost equation and a new one, the Jacobsen's equation. The Jacobsen equation gives better fit than the modified Chug-Pfost equation. The greatest discrepancy was under adsorption regime (from cooling aeration) conditions.
