Wet milling is milling using cutting fluid. Although dry milling can extend the tool life, the cost of cutting fluid treatment, health and safety issues are attracting more and more attention. The use of dry processing is a very valuable saving in technology, but in some cases, only wet processing can be selected.
While the wet milling process is capital intensive with higher operating costs, the ability to produce a variety of products can be valuable in dealing with volatile markets. The wet milling process results in slightly lower ethanol yields than a traditional dry milling process since some of the fermentable starch exits the process attached to the saleable co-products.
Wet mills need to be cleaned on a regular basis to remove the material that has collected in the mill. When considering the purchase of a wet mill, it is very important to determine how easy it is to access the coolant tank and filter, since you will be changing and cleaning these out weekly, in most cases.
