How Poor Deaeration Leads to Breaks, Spots, and Formation Issues
In paper manufacturing, consistent quality depends on smooth stock flow, stable wet-end conditions, and proper control of air and foam. One of the most common yet often underestimated issues in paper mills is poor Paper Machine Deaeration . When entrained air is not effectively removed from the stock, it creates multiple operational and quality problems, including sheet breaks, visible spots, and uneven formation. Understanding how poor deaeration affects the paper machine helps mills take corrective steps using proper deaeration systems and Paper Machine Defoamer solutions. What Is Paper Machine Deaeration? Paper Machine Deaeration is the process of removing entrained and dissolved air from pulp stock, white water, and process streams before they reach critical zones such as the headbox. Air enters the system through agitation, pumping, chemical reactions, recycled fiber processing, and closed water loops. If this air is not removed, it travels with the stock and disrupts flow, ...
