The Core Processes for Coir Desalination and Dewatering: Spray Washing + Mechanical Pressing
The desalination and dewatering of coir typically constitute an integrated, continuous process flow, rather than a task performed independently by a single piece of equipment. The fundamental principle can be summarized as "wash first, then press":
Desalination (Salt Removal) Phase: This stage involves spraying the coir with fresh water to rinse it, thereby dissolving and flushing away its salt content. To enhance efficiency and conserve water, this phase typically employs multi-stage spraying or counter-current washing methods.
Dewatering (Pressing) Phase: The coir—which retains a high moisture content following the washing process—is subjected to intense mechanical pressure to squeeze out the water, thereby reducing its moisture level to a point suitable for subsequent drying treatments or direct use.
