Description

Technical Field

[0001] The utility model relates to the technical field of production of Chinese medicinal slices, in particular to a water-flying stone mill for the production of Chinese medicinal slices. Background Art

[0002] Water flying method is a method of preparing traditional Chinese medicine. It is a method of preparing extremely fine powder of medicinal materials. The principle is to use the different suspension properties of coarse and fine powders in water. Water-insoluble medicinal materials such as minerals, shellfish and other medicines are ground with water and prepared into extremely fine powder through repeated grinding. Water flying method is suitable for water-insoluble mineral medicines such as cinnabar, realgar, calamine and shellfish Chinese medicines. Water flying method can remove impurities and water-soluble toxic substances in the medicine, such as arsenic and mercury, thereby purifying the medicine, making the medicine fine in texture, and convenient for internal and external use. It can also prevent the medicine from flying dust and polluting the environment during the grinding process.

[0003] In the prior art, when a water-flying stone mill is used to grind drugs, a semi-mechanical grinding method is usually adopted. First, the drug is placed in a container and crushed appropriately. Then the crushed drug is placed in a stone mill, clean water is added and ground into a paste, and then a large amount of water is added and stirred. At this time, the coarse particles sink, and the suspension is poured out. The sunken coarse particles are ground again, and water is added, stirred, and the suspension is collected. The process of grinding the coarse particles is repeated until the coarse particles are finely ground. Finally, when the liquid is no longer suspended, the remaining impurities are discarded, the suspension is allowed to stand, the clean water is removed, and the remaining precipitate is ground into fine powder. The powder is the ground drug for the production of Chinese herbal medicine slices.
