Core Processes for Coir Desalination and Dewatering: Spray Washing + Mechanical Pressing
The desalination and dewatering of coir typically constitute an integrated, continuous process, rather than merely an isolated task performed by a single, standalone piece of equipment. The core operational logic adheres to the principle of "wash first, then press":
Desalination (Salt Removal) Stage: This stage involves spraying the coir with fresh water to rinse it; this dissolves the salts present within the material, allowing them to be carried away by the water flow. To maximize washing efficiency and conserve water, multi-stage spraying or counter-current washing methods are typically employed.
Dewatering (Pressing) Stage: Following the washing process—during which the coir becomes fully saturated with water—the material is subjected to intense mechanical pressure. This pressure squeezes out the moisture, reducing the water content to a level suitable for subsequent drying or immediate use
