Coir Pith Dual-Roller Press Dewatering Equipment: Achieving Simultaneous Desalination and Dewatering

How does the high-pressure roller press technology for coir pith achieve simultaneous "desalination + dewatering" in a single step? The reason this equipment delivers such outstanding results is that it ingeniously integrates the two distinct processes of dewatering and desalination. **Preliminary Dewatering and Humidification-Assisted Desalination:** Upon entering the machine, the coir pith first undergoes preliminary dewatering via a set of opposing pressure rollers. Subsequently, the upper and lower mesh belts briefly separate; within this separation zone, spray nozzles mist the material to humidify it—a critical step that effectively dissolves and flushes out the salts embedded within the coir fibers. **Deep Dewatering and Forming:** Once the desalination stage is complete, the coir pith is once again gripped between the upper and lower mesh belts and conveyed into a high-pressure zone, which consists of a large screen roller and multiple sets of pressure rollers. Through a series of repeated, progressive, and intense compression cycles, the moisture content is reduced to a minimum, ultimately resulting in the output of a filter cake with extremely low residual moisture. The entire process features a high degree of automation, and the equipment boasts a sophisticated structural design, thereby effectively resolving the complex challenge of "coir pith desalination treatment."
