There are many varieties of traditional Chinese medicine, and smashing is the basis of traditional Chinese medicine preparations. Therefore, the current Chinese medicine pulverizer market can be said to be a hundred schools of flowers contending, and Chinese medicinal materials must be crushed before preparation. A suitable comminution method is one of the prerequisites for ensuring the quality of the preparation. Now we will make a simple introduction to the four methods of traditional Chinese medicine crushing. 1. Dry crushing: Dry crushing, also called conventional crushing, means that the medicine is pulverized after proper drying treatment. 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 drug in the prescription is 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) Blending method: also known as string oil, the prescription of small "oily" large materials will be left first, the other drugs will be pulverized into powder, and then the mixed powder will be incorporated into the Taiwanese "oily, medicinal materials smash once The drug that is first crushed can absorb the oil in time, and does not stick to the crusher and the sieve hole. Add the hemp kernel, almond, melon wilt, Yu Liren and so on.
(4) String milling method: also known as string material, which will leave the “sticky” material in the prescription, first mix and pulverize other medicine materials into coarse powder, and then use this mixed medicine material to gradually incorporate “viscosity% medicine”. The material 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 land, Scrophulariaceae, Codonopsis pilosula, and longan meat.
Some drugs will stick to the device or be agglomerated 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. There are three kinds of grinding water flying method, wet grinding method and co-dissolving grinding method.
(1) Grinding water flying method: that is, the fine powder of the drug is used to separate and purify the fine powder in the suspension of 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 put 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 applicable to some Dry smashing drugs that are easily bonded into a block, such as borneol, camphor, etc.
(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.
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.
