【Technical Introduction】
This technology establishes a robust, localized supply chain by integrating three core pillars: raw material purification, component manufacturing, and system integration.
1. Sustainable Material Purification: The process begins with the chemical extraction of alumina-based circular products from aluminum industry waste. This method achieves an aluminum purity of 90 wt%, with active alumina reaching a specific surface area of over 300 m2/g. This high surface area ensures exceptional adsorption characteristics. By repurposing industrial waste, the technology eliminates the need for mined natural bauxite, significantly reducing both raw material costs and the overall carbon footprint.
2. Advanced Component Manufacturing: Utilizing these recycled materials, a proprietary ceramic slurry is uniformly coated onto a porous foam carrier. This structure is then sintered at high temperatures (1,200-1,500°C) to remove organic matter, resulting in a durable, porous ceramic framework. We can produce desiccant wheels with diameters of 100-500 mm, thicknesses of 50-600 mm, and porosities of 50-80%. Rigorous testing over 101 days of continuous operation has proven that these components maintain full functional adsorption without structural degradation.
3. Intelligent System Integration: The complete system integrates a 50 cm diameter adsorption wheel with a PTC ceramic heating regeneration module and an intuitive Human-Machine Interface (HMI). By leveraging a sensor-driven dynamic control logic, the system intelligently adjusts regeneration power. This optimization ensures stable airflow while minimizing energy consumption.
Unlike traditional hot-air drying, which can damage heat-sensitive materials, this system utilizes a low-temperature dehumidification principle. It consistently maintains an ideal environment: 25-30°C with a relative humidity of 15-35%, making it a superior solution for precision industrial applications.
【Project Planning/Technical Applications】
This technology encompasses raw material processing, component manufacturing, and system integration. The resulting equipment is oriented toward real-world field validation, with a primary focus on drying processes sensitive to temperature and humidity. The system’s performance was verified through practical testing on agricultural products, specifically garlic and vanilla pods. For garlic drying, compared to traditional methods, the drying time was slashed from 25 days to 12 days, while process energy consumption was reduced by 14%. For vanilla drying, the drying cycle was shortened from 45 days to just 19 days, achieving a significant energy saving of 53.7%.
【Future Development】
Moving forward, the strategic roadmap for this technology focuses on localizing the entire supply chain and optimizing product costs to achieve 100% "Made in Taiwan" production through technology transfer, effectively breaking the current import monopoly on critical dehumidification components. By leveraging economies of scale and integrating a comprehensive upstream and downstream industrial network, we aim to reduce the manufacturing cost of mass-produced equipment by more than 30% compared to current prototypes. Furthermore, we plan to pursue carbon footprint certifications and green labels in collaboration with accredited institutions to quantify the carbon reduction benefits of both equipment construction and operation, thereby strengthening the product's competitiveness and expansion into international markets.
