The newly invented “Lyophilization Process for Low Ethanol Residue Heparin Calcium” primarily addresses the drying of heparin products and can be applied to the drying of all similar products. By subjecting the product to vacuum distillation, supplementing with purified water for dilution, maintaining a fixed lyophilization concentration and thickness, and removing both water and organic solvents from the product, this process not only effectively eliminates moisture and organic solvents but also ensures that the product’s structure remains unchanged. As a result, the ethanol content in the product is reduced, leading to improved product quality.

The grant of this invention patent has established a solid technological barrier for Hubei Enoray Biopharmaceutical Co., Ltd. in the production of heparin-based products, fully demonstrating the company's independent R&D and innovation capabilities. This will help the company to further improve its intellectual property protection system, establish a sustainable innovation mechanism, maintain its technological leadership, enhance its core competitiveness, and provide strong technical support for the company's future development, while also having a positive impact on its continued growth.
