Module 3 - Mill Processes & Performance Q. Why don’t millers do more to reduce milling loss? A. Milling loss should not be confused with invisible loss. It is only a loss of moisture not a loss of material. Millers aim for a finished product moisture and the wheat is conditioned to compensate for this loss.If the loss is high the miller loses a small amount of capacity which may have a cost but the measures needed to reduce the milling loss i.e. control of humidity to the mill/ climate control have a high capital cost and a significant running cost. In regions that experience extremes of climate it may make economic sense or be otherwise desirable for performance / quality considerations to invest in such measures. In the UK this is not the case. In the past mills had lower losses because they use significantly less air because they used elevators for conveying stock but they suffered from higher maintenance costs and hygiene issues and the benefits of moving to pneumatics far outweigh the increase milling loss.   close window
