Improving Flaker Productivity - a Case Study
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.

The Causes of Flooding in Paper Dryers
The majority of flooding incidents can be attributed to steam and condensate system issues (poor equipment sizing, incorrect system set-points and incorrect system calibration) and mechanical issues (unreliable or incorrectly installed steam joints and syphons). In this discussion, we will focus on the steam system issues that contribute to flooding.
