Blind drilled, grooved, and suction drilled rolls are commonly used on presses in the papermaking process. The open areas in these rolls are designed to accept water from the fabric.

Often the goal for roll cleaning is to prevent contaminants from getting into the finished product. However, for the flaking industry, application-specific doctor blades provide a different function. 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.
