Dry crushing
Dry pulverization, also called conventional pulverization, is a commonly used method for pulverizing zui of traditional Chinese medicine, which means that the drug is pulverized after being properly dried. For example, it is pulverized by an iron grinding ship, a ball mill, a boring machine, a universal pulverizer, etc. The advantage of this method is that the operation is simple, and the powder is formed at one time, and the disadvantage is that the continuous operation is easy to generate heat and cause combustion. In the actual operation, the following four methods are divided according to the different drug textures.
(1) Separate pulverization means that the scented medicine is pulverized separately. This method is applicable to the pulverization of resin, colloid, precious, poisonous and small-sized seed medicines.
(2) Mixed pulverization means that all or part of the medicinal materials in the prescription are blended together for pulverization. It is suitable for the smashing of group drugs with similar texture in the prescription. This method can avoid the difficulties caused by the viscous or oily smashing process. Such as the refinement of rehmannia, angelica, apricot and other drugs.
(3) The method of mixing is also called string oil. The medicine with a small "oily" prescription is left first, and other medicines are pulverized into powder, and then the mixed powder is successively incorporated into the table. "Oil, the medicine is smashed once. In this way, the first pulverized medicine can absorb the oil in time, and does not stick to the pulverizer and the sieve hole. Adding hemp kernel, almond, melon wilt, Yu Liren and the like.
(4) The string milling method, also known as the string material, is to leave the "sticky" material in the prescription, first mix and pulverize the other medicine into coarse powder, and then use the mixed medicine to gradually incorporate the "viscosity% medicine". It is pulverized once again. Its "sticky" substance is dispersed and adsorbed by the light-pulverized powder in the pulverization process. The smashing and sieving can be carried out smoothly*, such as raw ground, Scrophulariaceae, Codonopsis pilosula, longan meat, etc. Wet pulverization Some drugs will stick to the device or re-agglomerate into pieces (such as borneol) when pulverized and ground. If a proper amount of water or other liquid is added to the drug for pulverization, it is easier to form a fine powder. Commonly used grinding water flying method, wet grinding method And the co-dissolution grinding method, the more prominent grinding type Chinese medicine pulverizer is the model of this series of CHEN-300.
(1) The grinding water flying method separates and purifies the fine powder by utilizing the difference in the suspension property of the crude powder of the medicine in water, and the method is mainly applicable to some mineral-insoluble drugs and poisonous drugs which are insoluble in water. Such as realgar, cinnabar, talc, pearls and other drugs.
(2) Wet grinding method, also known as adding liquid grinding method G is to place the medicine in a wet pulverization container, or sprinkle a little water, ethanol or sesame oil on the medicine and then grind and pulverize. This method is mainly suitable for some dry The method smashes drugs that are easily bonded into a block, such as borneol, camphor, and the like.
(3) Co-dissolution grinding method When two or more drugs are mixed and ground into a fine powder, wetness or liquefaction occurs, and the method of grinding into a powder is referred to as a co-solution grinding method. Common are menthol and camphor, menthol and borneol.
Traditional Chinese medicine has a long history, while traditional Chinese medicine crushing Zui used manual, research and ship methods are inefficient and rough, and the development of modern technology has made a major change in the types of Chinese medicine crushers. According to the nature of traditional Chinese medicine itself, different types of crushers are selected. The pulverization efficiency and the pulverization fineness can be effectively improved. There are many different kinds of traditional Chinese medicines, which is why there are many types of traditional Chinese medicine crushers. At present, there is no Chinese medicine crusher capable of crushing all kinds of traditional Chinese medicines. For many manufacturers, the publicity should be polished, and users can The actual needs, according to the requirements of crushing Chinese medicine, there is a choice of Chinese medicine crusher.
