Coconut Fiber Powder Drying Systems 

Coconut fiber powder, produced by finely milling dried coir fibre to sub-millimeter particle sizes is a distinct product from both coco peat and standard coir fiber, finding specialized applications in composite material manufacturing, biodegradable packaging, horticultural growing media blending, paper and board reinforcement, and natural fiber-reinforced polymer composites. As the market for natural fiber composites in automotive, construction, and packaging applications grows, coconut fiber powder’s combination of natural cellulose and lignin content, low density, and good mechanical reinforcement properties make it increasingly attractive as a functional filler and reinforcement ingredient. Industrial production of coconut fiber powder requires that the input coir fiber be dried to below 8–10% moisture before milling, both to achieve efficient size reduction and to meet the moisture specifications demanded by polymer composite and adhesive manufacturing customers. Kerone Engineering Solutions designs dryer systems for pre-milling coconut fiber drying and post-milling coconut fiber powder drying tailored to these specific requirements.
