Fine grinding method for direct oral medicinal slice raw materials

Abstract

The invention discloses a fine grinding method for direct oral medicinal slice raw materials. The fine grinding method is fewer in processes, simple to operate, and does not need to excessively dry and remove oil in advance; high-speed gas flow is adopted to drive medicine particles to collide with a metal inner wall and a turning fork, so that collision force is greater and the crushing effect isbetter; a spray head alternatively sprays high-speed gas flow with the medicine particles, so that the motion of the medicine particles is more disordered, and collision frequency is increased; low-temperature nitrogen gas conveying is adopted throughout the process, so that the medicines are prevented from oxidizing and generating heat breaking; the raw material particles are embrittled, so thatcrushing degree is improved; and after the turning fork is collided, sound waves of various frequencies are not generated, so that Brownian motion degree of medicinal slice powder is increased, a sticking phenomenon is weakened, and the crushing effect is further improved.

Description

technical field [0001] The invention relates to the field of pulverization of oral decoction pieces, in particular to a fine grinding method for direct oral decoction pieces raw materials. Background technique [0002] Drugs are processed from raw materials into oral decoction pieces and need to be ground. The purpose of grinding drugs is to make the drug more prominent and easier for patients to absorb. Therefore, the grinding standard of oral decoction pieces is generally the more broken the better, and it needs to be ground into powder, preferably micro powder. [0003] The common methods of manual or mechanical grinding are difficult to grind oral decoction pieces into fine powder, and the precision is not high enough. Therefore, the most widely used micronization equipment for oral decoction pieces is the jet mill, and the fine grinding method of raw materials for oral decoction pieces is also designed around the jet mill. [0004] However, our company found in produc...

Problems solved by technology

[0005] Among them, moisture is relatively easy to solve, and most of the medicinal materials need to be dried or sun-dried. Although the moisture cannot be completely removed, it is not satisfactory.

The problem of oil and fiber is more difficult to solve. For fiber, crushing itself is the process of breaking the fiber; for oil, some drugs are not suitable for removing too much oil, after all, some trace elements are fat-soluble

[0006] Therefore, the fine grinding method designed with the jet mill as the core is often very cumbersome, with many processes, and the fine grinding effect of many raw materials for decoction pieces is not good enough, and may damage the medicinal properties. The most important thing is that some medicines are really not suitable for jet mills. crush
