Coir Dust Drying Systems 

Coir dust – the fine, powdery fraction separated from coir fiber during the defibering and cleaning process has emerged from obscurity as a waste stream into a commercially significant material in its own right. With particle sizes typically below 2 mm and a composition rich in lignin and cellulose, coir dust is used in horticulture as a soil amendment, in brick manufacturing as a fuel additive, in mushroom substrate preparation, and in the production of combustion pellets and briquettes for industrial energy use. Fresh coir dust from processing operations contains moisture levels of 50–75%, which must be reduced to below 12–15% for briquetting applications and below 20% for horticultural bagging. The challenge of industrial coir dust drying lies in managing its extremely fine particle size, high surface area, and tendency to form airborne dust clouds during pneumatic handling and thermal processing. Kerone Engineering Solutions designs industrial coir dust drying systems specifically engineered to handle these challenges safely and efficiently.
