Ultra-low temperature comminution technology is one of the important powder processing technologies. First, the material that is difficult to be crushed at room temperature is cooled to below the embrittlement point, and then it is crushed to the required fineness in the shredder, and the original component is not ensured. damage. The process uses liquid nitrogen or air as the refrigerant medium, wherein the air cooling is much lower than the cost of using liquid nitrogen. At present, China's ultra-low temperature micro-powder preparation technology has not yet been made domestically, and foreign countries have imposed a technical blockade on it. Therefore, the independent development of ultra-low temperature micro-powder preparation technology has become one of the key ways to improve the level of Chinese medicine research and development, and the development of cryogenic refrigeration using air as the refrigerant medium. Crushers and complete sets of equipment are new topics that China needs to focus on.
According to reports, the complete set of equipment will have independent intellectual property rights after its successful development. Its innovation lies in the organic combination of an air-turbine expansion ultra-low temperature cooling device and a pulverizer to achieve complete, energy-saving and good crushing characteristics of the system; The cutter shape and smashing structure achieve the ideal smashing effect; the ideal ultra-low temperature material is selected to ensure the stability of the equipment; the automatic control system is adopted to achieve a good man-machine interface control. The complete set of equipment will use an air-based ultra-low temperature freezing device prepared by aerospace technology to crush materials that are difficult to crush at room temperature, such as Chinese herbal medicines, high value-added foods, animal bones, and high-value biological materials, such as heat-sensitive and heat-prone materials. The easily decomposable substances can greatly improve the fineness of these substances through low-temperature crushing; in addition, due to the different embrittlement temperatures of different materials, selective comminution can be performed through low temperature, and a pure single powder can be finally obtained. The device will effectively improve the efficacy of Chinese medicine and the absorption of health products, thereby enhancing the core competitiveness of the biomedical industry.
Fengli Biopharma Crushing Equipment Development Supported
Zhejiang Fengli Crushing Equipment Co., Ltd. and China National Aviation Industry Corporation No. 609 Institute developed a set of equipment for the preparation of ultra-low temperature micropowder for biomedical engineering. Recently, it was selected as a key scientific research project of the 2006 Zhejiang Provincial Science and Technology Plan. The development of this project will solve the problem of comminution of bio-pharmaceutical materials that are difficult to smash at room temperature, and provide new equipment for the production of high-value-added powder materials for the bio-pharmaceutical industry in China.
