Wet milling initially accounted for most of the ethanol fuel production in the United States, but new construction has shifted to dry mills, partly because dry mills cost less to build. Dry-milling plants have higher yields of ethanol. The wet mill is more versatile, though, because the starch stream, being nearly pure, can be converted into ...

Glucose, maltose and maltotriose were more rapidly transferred into sweet worts at the early stages of lautering (40 hL and/or 80 hL of wort) after wet milling in comparison to dry milling. Total protein content in the test worts was significantly higher than in the corresponding reference worts at each stage of lautering.

There are two main distillery processes: dry-milling distillery and wet-milling distillery. The dry-milling (or dry-grind) process is the main process for producing ethanol. This process starts with removing the bran by grinding before steeping the grain in water and results in ethanol and various "distillers" by-products.

On the Certificate of Analysis, the friability for most malts should be greater than 90%. This is an indication of good malting practice. As a rule of thumb, friable malts are broken apart easily in the mill and produce finer grists. Therefore, they only need simple milling malt equipment, like a 2 roller mill.

The terms wet milling and dry milling are overarching concepts that do little to actually describe the processes and forces involved. But some methods are only possible under wet conditions, and some require dry milling conditions. Although the goal of both grinding methods is to reduce particle sizes to a target range, the processes are different.

The more extensive the malt is milled, the greater the extract production. However, the fine grind can lead to subsequent wort separation problems and a loss of extract in the spent grains during wort separation. As a result, the brewer needs to consider the equipment used in the brewhouse when determining the particle size when milling the malt.

Milling the grains allows access to the malt contents for mashing. Malt milling is usually done dry, but did you know that malts can also be moistened for milling? Humidifying the malts for milling has several advantages. Dry milling has the inconvenient of fragmenting the malts, which can cause difficulties when filtering the wort through them.

The LOX explanation does not make much sense to me as malt is dry, so until it touches the water, I cannot see that 10-15 min or less from milling to dough-in will make a big difference. Yes, PPO can oxidize fruits very quickly when exposed to oxygen but fruits are mostly water; grains at 5% moisture cannot oxidize that fast.

In wet milling, malt is steeped in a continuous stream of warm water to bring the husk moisture content up to 15%, before the malt is ground on a pair of specially designed rollers. In wet milling, the grain husk remains mainly complete, whereas in a dry mill it can fragment. This fragmentation can slow run-offs and cause quality problems.
