Drying rate formula
WebJan 21, 2024 · Where the drying rate is reduced by a factor f then this can be incorporated to give: Dt = w (DX)/ f(dw /dt)const. and this has to be integrated piecemeal down to X = … WebDrying of grain involves exposing grain to air with low relative humidity which will lead to evaporation of the moisture in the grain and then the moisture’s removal away from the grain. The process includes: moisture removal monitoring drying periods (pre-heating, constant rate, falling rate) increasing drying rate at 18% MC uniform drying
