Application of airflow pulverization technology in fine processing of traditional Chinese medicine

Crushing is a vital step in the processing of traditional Chinese medicines and their preparations. However, conventional crushing equipment has limitations in terms of particle size control, powder yield, collection efficiency, and preservation of active ingredients. Materials that are heat-sensitive, have low melting points, or are easily degraded during processing often cannot be effectively crushed using traditional methods. Additionally, China is rich in traditional Chinese medicine resources, but past extensive processing techniques have struggled to meet modern production demands. Airflow crushing technology offers a promising alternative for producing ultra-fine Chinese medicine powders with enhanced therapeutic effects and greater variety. Airflow pulverization utilizes high-speed air streams to impart significant kinetic energy to materials, causing intense collisions, friction, and shearing within the grinding chamber. This process enables the production of very fine powders (less than 10 μm). It is widely used across industries such as chemicals, pharmaceuticals, food, plastics, mining, and metallurgy, and holds a special place in specific powder applications. Key features include: 1. **Low temperature**—due to the Joule-Thomson effect, the gas cools itself during expansion, reducing heat generated by collisions. 2. **High efficiency**—short processing time, high powder collection rate, and minimal dust leakage. 3. **High purity**—reduced contamination and uniform particle size distribution (up to D95). 4. **Versatility**—can handle wet materials and perform simultaneous drying. 5. **Integration**—allows for multiple operations, including drying and classification. In the context of traditional Chinese medicine, airflow pulverization is still in its early stages, with many challenges remaining. The controllability of the process is critical, especially given the unique characteristics of herbal materials compared to inorganic substances. Research focuses on optimizing the preparation process, including pre-crushing, air milling, cyclone separation, and quality control. Parameters such as moisture content, jet mill settings, and classifier performance must be carefully studied and adjusted. Choosing appropriate quality indicators is also essential. Traditional Chinese medicine powders consist of many particles, and their properties depend on both individual particle characteristics and inter-particle interactions. Important parameters include particle size, distribution, surface area, wettability, and flowability. Applying ultrafine powders in traditional Chinese medicine requires addressing issues like particle aggregation, extraction efficiency, dissolution behavior, and pharmacodynamic validation. Surface treatments and advanced packaging can prevent agglomeration, while optimized extraction conditions and dissolution testing ensure efficacy. Pharmacodynamic studies suggest that ultrafine powders may enhance bioactivity, though more research is needed to establish reliable verification methods. Currently, only a limited number of Chinese medicines have been processed using airflow technology, mainly high-value herbs like ginseng, pearl, pollen, and others. While initial results are promising, broader commercial application is still in its infancy. Introducing this technology into traditional medicine processing not only enriches traditional methods but also brings innovation to the industry, creating new growth opportunities. Ultrafine pulverization improves solvent contact during extraction, leading to faster, more efficient processes and better resource utilization. In solid dosage forms, it enhances solubility, dissolution, absorption, and bioavailability. Overall, the full integration of airflow pulverization technology has the potential to significantly advance the modernization and technical development of traditional Chinese medicine.
