Innovation Breakthrough: An In-Depth Analysis of Guangdong Yinghui's Patented "Label Paper Drying Device"

In the field of label paper production equipment upgrades, Guangdong Yinghui's "A Label Paper Drying Device" (Patent No.: ZL 2022 2 1751396.X) addresses a 30-year-old drying issue. Traditional one-way hot air drying is characterized by high energy consumption, uneven drying, and low adaptability. Yinghui's technology increases drying speed by 50%, reduces energy consumption by 35%, and lowers the defect rate to 0.3%.

The key technology of the patent is impressive. The dynamic multi-directional hot air system, featuring a 3D rotating frame, increases coverage by 70% to eliminate edge warping and adjusts air volume based on material thickness (30 - 500 g/㎡) for all types of materials. The turbulence-enhancing technology employs a patented component to generate turbulence, improving heat exchange efficiency by 60% while maintaining a stable surface temperature (≤ ±1.5℃). Additionally, the energy-saving system recycles 92% of waste heat, reduces carbon emissions by 15 tons per device annually, and complies with EU ErP standards with a noise level of ≤ 68 dB.

In various scenarios, it performs exceptionally well. In high-precision e-label production, it addresses overheating issues, achieving a yield of 99.9% with a temperature control of ±1℃. For specialized paper, multi-wind compensation ensures that flatness error is maintained at ≤ 0.1 mm. For small-batch orders, it reduces line-change time from over 2 hours to just 5 minutes.

Data demonstrates its success. A company saved over 3 million yuan in electricity by utilizing 10 devices, reducing the return on investment (ROI) to just 11 months. SGS testing indicates a 40% improvement in adhesive stability at 85°C and 85% relative humidity. Additionally, it has been recognized as a top energy-saving product by the industry, establishing a high standard.
