Moisture in Grain, Hygroscopic Equilibria of Rough Rice at Elevated Temperatures

Low-temperature, low-relative humidity drying of rough rice

“…Column and crossflow dryers generally operate at 45-78°C (Calderwood, 1975;Hogan and Karon, 1955). Some multi-stage driers have been reported to operate at temperatures as high as 80-200°C (Inprasit and Noomhorm, 2001).…”

Influence of Milling Parameters on Head Rice Recovery: A Review

“…A temperature of 45-78°C is used in column and cross flow dryers whereas some multi stage dryers operate at temperatures as high as 80-200°C. These high temperatures are the main cause of kernel fissuring and breakage during milling (Inprasit and Noomhorm, 2001;Calderwood, 1975;Hogan and Karon, 1955). As high temperature drying establishes a MC gradient between the surface and the centre of the kernel due to evaporation from the outer layers of the kernel (Siebenmorgan et al, 2004).…”
