Maize is processed by dry or wet milling. Dry milling may or may not include degerming as a preliminary step. Nondegerming dry milling is carried out on a local basis in small grist mills or in modern roller mills using sifters and purifiers. The maize is ground to make coarse wholemeal of 85 95% extraction rate.

Corn wetmilling process. In wet milling process, the corn kernel is separated into three parts in an aqueous medium prior to fermentation: (1) the hull, (2) the germ, and (3) the endosperm. The primary products of wet milling include starch and starchderived products ( high fructose corn syrup and ethanol), corn oil, and corn gluten.

For example, dry milling using a fluid energy mill (often referred to as "jet milling") or mechanical impact is a well established and efficient way of ensuring delivery of a required particle size [9,10,11,12,13]. However, it comes with a cost in increased processing time and a likely reduction in process yield (as will be discussed later).

Wetmilling is a process in which feed material is steeped in water, with or without sulfur dioxide, to soften the seed kernel in order to help separate the kernel's various components. For example, wetmilling plants can separate a 56pound bushel of corn into more than 31 pounds of cornstarch (which in turn can be converted into corn syrups ...
