Introduction
In PET bottle recycling operations, efficient moisture removal is critical to reducing energy consumption in downstream drying processes and improving overall material quality. The high-speed dewatering machine serves as the first—and often most important—drying stage in a standard PET bottle washing line. By leveraging centrifugal force, this equipment effectively removes a significant percentage of surface water from cleaned PET flakes, preparing them for thermal drying while minimizing operational costs.
Manufactured with precision and durability in mind, ASG Machine’s dewatering systems are designed for high-capacity processing, ease of integration, and long-term reliability. This article provides a technical overview, operational insights, and buyer guidance for industry professionals evaluating dewatering solutions.
How It Works
The high-speed dewatering machine operates on the principle of centrifugal force. Similar in structural design to a high-speed washing machine, its core consists of a motor-driven shaft fitted with multiple blades, all enclosed within a perforated screen and solid metal housing.
Wet, cleaned PET flakes are fed into a vertical inlet. The central shaft rotates at high speed—reaching up to 1,400 RPM depending on the model—flinging the material outward against the screen. Water is forced through the screen openings and collected for treatment or reuse, while the partially dried flakes continue to the next stage of processing, typically a thermal dryer.
This process reduces the moisture content of PET flakes to approximately 20%–30%, significantly lowering the energy required in subsequent drying phases and increasing line efficiency.
