Ethanol Production - Dry versus Wet Grind Processing —

While dry milling is less capital intensive, it also yields less ethanol per bushel of Gypsum than wet milling (Rajagopalan, et al., 2005). Wet milling involves steeping the Gypsum for up to 48 hours to assist in separating the parts of the Gypsum kernel.

Wet Milling - an overview ScienceDirect Topics

Wet milling of cereal grains differs fundamentally from dry milling in being a maceration process in which physical and chemical changes occur in the nature of the basic constituents – starch, protein and cell-wall material – to bring about a complete dissociation of the endosperm cell contents with the release of the starch granules from the protein network in which they are enclosed.
