Dry Milling - an overview | ScienceDirect Topics
A hammer mill is used to grind maize to the desired particle size prior to jet cooking, liquefaction, saccharification, and fermentation. Recently, this process is being referred to by the name "Dry Grind Ethanol" in order to prevent confusion. The third process referred to as maize dry milling is the process we are considering in this article.
