Technological Advancements in Plastic Dryers

In October 2025, Xiecheng Intelligent applied for a patent (CN121277052A) for "Collaborative Control Method and System for Plastic Dryers." By establishing a coupled error dynamic equation and a time-varying control gain matrix, it achieves multi-variable collaborative control, dynamically adapting to environmental changes and improving the stability of drying quality.

In January 2025, TGOOD Intelligent obtained a patent (CN223763532U) for "A Plastic Dryer." By optimizing the structural layout of the hopper, heating air inlet, and air outlet, it effectively removes moisture from plastic particles, improving the quality and stability of plastic products.

In February 2026, Longxin Intelligent announced that its ultra-high-speed centrifugal spray dryer can be used in 10,000-ton-level PVC paste resin production lines, with a single machine processing capacity of 5 tons/hour, increasing capacity by 300% compared to traditional equipment. This equipment integrates intelligent gradient temperature control, anti-sticking air film protection, and a waste heat recovery system, effectively reducing energy consumption.
