The pulverization process of solid drugs generally utilizes external mechanical force to partially destroy the cohesive force between the molecules of the substance, so that the large pieces of the drug become small particles, and the surface area is increased, that is, the process of converting mechanical energy into surface energy. The pulverization of oily Chinese medicine is complicated, and it contains a certain amount of water (generally about 9%-16%) and has toughness. The less the water content, the more brittle the medicinal material is, and the more favorable it is to crush, so it should be smashed before smashing. The characteristics are properly dried. Thin-walled herbs such as flowers, leaves and some rhizomes are easily crushed. The woody long-horny structure of the medicinal materials, containing viscous or oily medicinal materials and animal ribs, bones, and nails are not easy to smash, and the optional air-selective Chinese medicine pulverizer. Some Chinese medicines are strong in oiliness and tend to stick to the pulverizer and sieve when pulverized, making it difficult for the medicinal materials to pass through the sieve holes. Although it can be pulverized together with other medicinal materials, it is easy to adhere to the pulverizer and it is difficult to sift. , the crusher is easy to bond the crusher. When dealing with biopharmaceuticals, we often use the following two methods to achieve satisfactory results.
First, cut the raw ground into 2 to 4 mm thick slices, put them into a suitable container, and then pour an appropriate amount of water of about 100 °C into the container of the medicine. Add the boring to the medicine when the water is drained, and take it out. It is placed in a milling tank and ground into a mud. Then, other Chinese herbal medicines crushed into coarse powder are added and crushed into pieces, which are sufficiently dried at a low temperature (below 60 ° C) and then pulverized to a desired fineness.
Second, the string of oil: the prescription of the "oily" large drug residue, first mix the other ingredients into a fine powder, and then use the sub-mixed powder into the "oily" drug, and then smash once. In this way, the oil can be absorbed in a timely manner by repeatedly pulverizing the drug, and the oiliness of the powder is lowered, so that it does not adhere to the pulverizer and the sieve hole. For example, Baizi Yangxin Pills in Baiziren, Suanzaoren and Schisandra; Maren Pills or Ma Ren, bitter almonds, etc. are all used in the "string oil" operation when crushing.
