What is Ultrafine Grinding Technology and Its Uses ?

Ultrafine grinding technology is widely used in the manufacture of ultrafine powders. It is mainly based on the principle of micron technology. By using grinding equipment, the high-speed rotating rotor generated by mechanical or fluid power is used to overcome the internal cohesion of solids by shearing, extrusion and grinding. Compared with various traditional grinding technologies, the products ground by ultrafine grinding technology have good solubility, dispersibility, adsorption. As well as special functions such as chemical activity and interfacial activity. All this is because this technology can make the particle size of the material smaller. At present, this superfine grinding technology is widely used in the field of traditional Chinese medicine and the food industry.

Overview of Ultrafine Grinding Technology

Superfine grinding technology refers to the use of mechanical or fluid dynamic methods to provide external force. Under strong impact, shear, friction and other effects, some chemical bonds between material particles are destroyed to generate new surfaces. Then, 0.5-5mm materials are crushed into micron-level or even nano-level particles. Ultrafine grinding technology can produce micron-level powders (1-100μm), submicron-level powders (0.1-1μm), and nano-level powders (1-100nm). It is a good material modification technology.

Classification and Main Technical Methods of Superfine Grinding

Ultrafine grinding is categorized by material and product particle size into coarse, fine, micro, and ultrafine grinding. In addition, based on the material state, it is divided into dry and wet grinding. To achieve desired results, common methods include air jet mill , ball mill, high-pressure homogenization, micro jet grinding, high-speed homogenization, colloid grinding, ultrasonic grinding, high-speed impact grinding, and sand milling. Specifically, dry grinding reduces particle size and improves elasticity, plasticity, or rigidity. Meanwhile, wet grinding is used for emulsifying and homogenizing liquids. Newer methods like vacuum ultrafine grinding, low-temperature milling, and cryogenic grinding help preserve volatile and heat-sensitive components during processing.

Advantages of Ultrafine Grinding in TCM Preparation

Ultrafine grinding offers clear benefits in Chinese (TCM). It reduces particle size, increases surface area, and improves solubility and absorption of active ingredients. This helps enhance effectiveness and speed up the onset of action. The process also protects heat-sensitive components and keeps the full range of pharmaceuticals compounds. It ensures uniform particle size, improving product stability and quality. Superfine grinding is widely used in making TCM granules, capsules, and fast-dissolving products, and supports the modernization of TCM production.

Application of Ultrafine Grinding in Food Preparation

Ultrafine grinding plays an important role in modern food processing. It actively reduces particle size to the micron or nano level, which significantly improves the solubility and absorption of nutrients. As a result, it helps the human body digest and absorb food more efficiently. Moreover, it enhances the texture and uniformity of products such as powders, beverages, and sauces, creating a smoother mouthfeel.

In addition, this technique preserves heat-sensitive nutrients, flavors, and aromas by avoiding high-temperature processing. Therefore, it supports the production of natural and high-quality food. Furthermore, manufacturers use ultrafine grinding to develop functional foods, dietary supplements, and clean-label additives. Overall, this technology promotes product innovation and improves nutritional value in the food industry.

Conclusion

In summary, ultrafine grinding technology has become an indispensable key process in many industries such as medicine and food due to its unique advantages in particle size control, functional enhancement and ingredient protection. With the increasing demand for high-quality and functional products, this technology will show greater development potential and market value in more application fields.
