Technological iteration empowers green transformation—how can the extruder industry seize new opportunities for high-quality development?
2026-05-14
Driven by China’s carbon peaking and carbon neutrality initiatives, the demand for recycling and reusing solid waste resources has been on a steady rise. Extruders have become indispensable equipment for solid-liquid separation and dewatering materials with high moisture content. Constant technical upgrades have helped these machines resolve many long-standing operational challenges in the industry, enabling enterprises across diverse sectors to cut energy costs and boost overall productivity.
Latest industry trends and real-world operational data from manufacturers show that the extruder market is evolving rapidly, with a clear shift toward smarter operation, higher efficiency and tailor-made application solutions. Leading manufacturers are actively scaling up R&D efforts and rolling out new technologies and products on a steady basis, which has become a key driver of high-quality development for the entire sector.
Extrusion dryers are widely deployed in environmental waste treatment, agricultural processing, plastic recycling, pharmaceutical production and many other industrial segments. Their operational performance directly determines the efficiency and quality of material processing, as well as compliance with current environmental production standards. Traditional extrusion dryers come with notable drawbacks: incomplete dewatering performance, high energy consumption and narrow application adaptability. These limitations make them ill-suited for today’s industrial demands for refined, eco-friendly production workflows.
Official industry statistics indicate that China produces over 26 million tons of waste textiles and more than 40 million tons of waste plastic film annually. The outdated performance of conventional extrusion and drying systems has severely restricted the improvement of national solid waste resource recycling rates.
To address these prevalent industry bottlenecks, domestic equipment manufacturers have significantly increased R&D spending, prioritizing technical innovation and product iteration. As a reputable enterprise in the field, Zhangjiagang Huixing Machinery Co., Ltd. dedicates 10% of its annual revenue to research and development. The company has built a professional cross-disciplinary technical team, holding 14 utility model patents and 6 independent computer software copyrights.
The company’s new generation of extrusion dryers is fully optimized to match the properties of different processing materials. Its waste fabric dewatering equipment adopts dual-roll progressive extrusion paired with intelligent pressure control technology, which reduces the moisture content of waste fabrics from 75% down to 12%, while keeping fiber damage rates below 5%. For PE film processing, its specialized dryer integrates screw pre-compression and dynamic screen separation technology, completely resolving the clogging and uneven dewatering issues that plague traditional devices. This model cuts per-ton energy consumption by 25% compared with standard industry levels. Meanwhile, the hydraulic-powered bag-type dryer supports bulk material processing with single-batch loads of up to 50 kilograms. It completes the full dewatering process in just 3 minutes, lowering material moisture from 80% to 10% and delivering a substantial boost in processing throughput.
Beyond targeted technical upgrades for segmented material processing scenarios, the entire extruder industry is advancing toward full-scenario compatibility and intelligent upgrading. Zhengzhou Dongding Drying Equipment Co., Ltd. recently delivered two large twin-screw extrusion dewaterers for a project in Ziyang, Sichuan. As an upgraded second-generation dewatering solution, this equipment outperforms traditional single-shaft models in both production capacity and energy efficiency.
Equipped with a hydraulically controlled conical discharge port, the machine supports flexible pressure adjustment, enabling efficient dewatering of high-moisture materials such as beer residue, pharmaceutical leftovers and food waste. Built with full stainless steel as standard, the equipment features strong corrosion resistance and easy daily cleaning, with customizable material configurations available to meet client-specific needs. Additionally, the belt press independently developed by Zhucheng Boyu Environmental Protection Equipment Co., Ltd. achieves full automatic operation covering feeding, pressing, filter cleaning and residue discharge. It is widely applicable for fruit juicing, traditional Chinese medicine extraction and vegetable processing, effectively solving the cumbersome operation and high maintenance costs associated with traditional processing equipment.
Industry market data forecasts that China’s screw dryer market size will reach 3.34 billion yuan in 2025, with a year-on-year growth rate of 12.4% — well above the average growth rate of the broader domestic drying equipment industry. By application, the environmental protection sector ranks as the largest single market, accounting for 33.5% of total industry output value. The agricultural waste resource recycling segment leads the industry in growth, with an annual growth rate of 18.6%. Market projections show the industry scale will expand to 3.75 billion yuan in 2026, with the market share of high-end customized equipment rising further to 35.2%. This signals a clear industry transition from blind scale expansion to high-value, quality-driven development.
Industry professionals note that extrusion dryers serve as core equipment for solid waste recycling and environmental governance, and their technical level directly determines the green transformation outcomes of downstream industries. Currently, intelligent manufacturing technology is deeply integrated with mechanical equipment manufacturing. Mainstream intelligent functions including IoT real-time monitoring, smart temperature regulation and variable-frequency speed control have been widely applied in modern extrusion dryers, greatly enhancing equipment operational stability and energy-saving performance.
Moving forward, sustained R&D investment and deeper collaboration between enterprises and research institutions will help the extrusion dryer industry break through core technical bottlenecks, expand application boundaries, and provide solid equipment support for the advancement of solid waste recycling and energy-saving environmental industries.
Furthermore, a growing number of domestic manufacturers are expanding into global markets. Their self-developed extrusion equipment has been exported to Southeast Asia, the Middle East and other overseas regions, helping promote Chinese extrusion machinery technology worldwide and contributing to global green and low-carbon development initiatives.
