In everything from potato starch flaking to pharmaceutical uses, the goal is to efficiently remove the product from the roll and generate maximum yield. So what benefit do roll cleaning and scraping technologies offer the flaking industry? The following case study illustrates how a specialized blade holder and flaking blade significantly increased productivity and decreased downtime.
