The most commonly used scope of the crusher includes food, chemical, Chinese medicine, etc., and the most complex and the most problematic is the number of Chinese medicine crushed, Chinese medicine crushed difficulties are mainly due to the complexity of Chinese medicine itself, some Chinese medicine contains oil and sugar, some avoid iron and some are high fiber, And Chinese medicine crushing is generally a variety of varieties mixed together, which increases the difficulty of crushing, below we will simply introduce several can improve the efficiency of Chinese medicine crusher in the crushing of Chinese medicine when the small methods, although can not fundamentally solve the problem of Chinese medicine crusher, but also to a certain extent to improve the crushing efficiency!
Dry crushing is the method of directly crushing dried medicinal materials. Medicinal materials should be fully dried by sun-drying, sun-drying, drying and other methods (generally, the moisture should be controlled below 5%) and then crushed. According to the characteristics of medicinal materials, mixed crushing, individual crushing or mixed crushing after special treatment can be used.
1. Mixed crushing (co-research) means that all or part of the drugs in the prescription are mixed together and crushed together after proper treatment. Most of the medicinal materials in the compound preparation were crushed by this method. The grinding and mixing operation are carried out together with high efficiency. However, when the prescription contains a large number of sticky and oily ingredients or animal skin, meat, bones and other drugs, it is easy to crush after special treatment. Common methods are: "string material", "string oil", "steam tank" and so on.
(1) Skewling (skewling) prescription has a lot of mucous, sugar or resin glue and other sticky drug materials, such as cooked ground, raw ground, wolfberry, jujube, longan meat, cornus officinalis meat, yellow essence, jade bamboo, aspiopogon, etc. When crushing, the drugs with low viscosity in the prescription are mixed and crushed into coarse powder first, and then the drugs with high viscosity are added successively and crushed again. Or the adhesive and other ingredients mixed together for coarse crushing, coarse crushing material and then spread to make large particles or small pieces, at 60℃ to fully dry, mixed and crushed again.
(2) String oil prescription contains a large number of oil ingredients, such as peach kernel, cypress kernel, sour jujube kernel, Perilla seed, walnut kernel and so on. When crushing, the drugs that are easy to crush in the prescription are first ground into fine powder, and then crushed by adding oil medicine; Or the oil drug is mashed into a sticky paste, mixed with other fine powder and then crushed.
(3) The steam pot shall wash the animal skin, meat, bones, etc. in the prescription, and put them in the steam pot together with the medicines required in the prescription and suitable for steaming, add an appropriate amount of yellow rice wine, etc., and then steam them thoroughly with water isolation or interlayer steam, and take them out after the liquid auxiliary materials have been basically steamed. In addition, the rest of the drug is ground into coarse powder, and then mixed with the steamed drug evenly, dry, and ground into fine powder. The varieties that need to be steamed before crushing are: Wuji Baifeng pills, Quan Lu pills, Da Buyin pills, etc.
2. Single crushing (single research) is a method of crushing a single drug. This method is applicable to: valuable fine materials such as borneol, musk, bezoar, antelope horn, etc.; Toxic drugs such as strychnine, red powder, etc.; Stimulant drugs such as toad venom; Oxidizing or reducing drugs, such as nitrate, sulfur, realgar, etc.; Resin gum, such as frankincense, myrrh, etc. There are also many cases that require single research, such as the drug that needs to be extracted separately in the preparation; Because it is hard in the prescription of powder drugs, it is inconvenient to crush together with the remaining drugs, and the drugs that need to be mashed and ground, such as Notoginseng and ochre. Some important fine materials have the traditional experience of individual crushing methods, such as cinnabar, ginseng, pearl, deer antler, incense, bezoar, amber, borneol, agarwood and sandalwood.
