The ultra-low temperature micro-powder preparation equipment, jointly developed by Zhejiang Fengli Crushing Equipment Co., Ltd. — a national key high-tech enterprise — and the 609th Research Institute of China National Aviation Industry Corporation, has recently been included in the 2006 Zhejiang Provincial Science and Technology Plan as a key research project (Project No. 2006C21056). This innovative technology addresses the challenge of grinding biopharmaceutical materials that are hard to crush at room temperature, offering new possibilities for producing high-value powder materials in the biomedical engineering sector. It holds significant economic potential and offers substantial social benefits.
Ultra-low temperature comminution is a vital process in modern powder technology, widely applied in fields such as drug development, health products, bioengineering, and food processing. The technique involves freezing materials below their embrittlement point at room temperature, allowing them to be crushed into fine particles without altering their original composition. Traditionally, liquid nitrogen has been used as a cooling medium, but this method is costly and not suitable for low-value products. In contrast, air-cooled cryogenic comminution is more economical and sustainable. Given China's specific conditions, the development of air-based cryogenic crushing systems represents a promising new direction for research.
Currently, China lacks a mature ultra-low temperature micro-powder preparation technology, while countries like Japan have restricted access to similar technologies. As a result, the advancement of this technology has become a critical step in improving traditional Chinese medicine production methods.
Zhejiang Fengli has achieved a major breakthrough with this complete set of equipment, securing its own intellectual property rights. The innovation lies in the integration of an air-turbine expansion ultra-low temperature cooling system with a crusher, ensuring a more energy-efficient and effective crushing process. The design features an optimized crushing gap, tool shape, and structure to achieve ideal results. High-quality ultra-low temperature steel is used to guarantee equipment stability, and an automated control system provides a user-friendly interface for operation.
This advanced system uses aerospace-derived air-based ultra-low temperature freezing technology to process difficult-to-crush materials such as traditional Chinese medicines, high-value foods, animal bones, and heat-sensitive biological materials. By reducing the temperature, the fineness of these substances is significantly improved, and selective crushing based on material brittle points allows for the separation of pure, single-component powders. Its application not only offers ideal cryogenic processing solutions for various industries but also enhances the core competitiveness of related sectors through technological breakthroughs. For instance, ultrafine herbal medicine powders can greatly improve product efficacy, while ultrafine bioengineering materials enhance the absorption of health products.
