Introduce the method of ultrafine grinding of Chinese herbal medicine
Date:2020-04-23
Chinese medicine crusher can grind Chinese medicine into flour as fine, it is powerful, can crush a variety of different types of Chinese herbal medicine, processed Chinese medicine products can meet international standards. The Chinese medicine pulverizer can effectively improve the traditional extraction process. After ultrafine crushing of traditional Chinese medicine, the contact area with the solvent is greatly increased, which can shorten the extraction time, improve the transfer rate of active ingredients, save energy, and improve the comprehensive utilization of raw materials.
In addition, the Chinese medicine pulverizer can also retain the active ingredients well. Relevant experts said that for many precious Chinese medicinal materials, the effect of crushing with a Chinese medicine crusher is better. For example, crushing Ganoderma lucidum, Ganoderma lucidum is rich in amino acid trace elements, and crushing by ultrafine pulverizer can make these substances play a better role.
From the perspective of materials research, Chinese medicine can be divided into plants, animals and minerals. Mineral Chinese medicines such as keel and magnet belong to inorganic non-metallic mineral materials, and the crushing method is the same as the crushing mechanism and the ultra-fine crushing mechanism of non-metallic ores. Animals such as whole insects, scorpions, etc., are dried (or freeze-dried) and then crushed. Because animals contain a lot of fat, crushing is difficult; Plants such as ginseng, Panax notoginseng, goji berries, etc., must be treated separately according to the actual situation, and the fineness of crushing can generally be between 3~5μm and 40~50μm. The crushing methods are mechanical crushing, vortex milling, vibrating milling and airflow crushing. Most of China's traditional Chinese herbal medicine crushing is mechanical crushing, which can meet the requirements of the production process of pills, powders, ointments, pills, etc.
The methods of ultrafine crushing of traditional Chinese medicine include mechanical crushing, vibration grinding crushing, airflow crushing, etc. Among them, the mechanical crushing fineness can reach 80 mesh, and the adjustment of crushing fineness is controlled by the screen of the inner cavity of the equipment. Vibrating grinding crushing can be used in the ultra-fine crushing of traditional Chinese medicine, and the fineness of crushing is between 1~40μm. The fundamental difference between airflow crushing and the above crushing is that the crushed object is impacted and crushed through high-speed airflow, and the fineness of crushing can reach 1~10μm, even below 1μm, which is also a method that can achieve fine physical ultra-fine processing at present.
