A kind of raw material fine grinding method of direct oral decoction pieces

Abstract

The invention discloses a fine grinding method for raw materials of direct oral decoction pieces, which has fewer procedures and simple operation, and does not need excessive drying and degreasing in advance; the high-speed airflow brings the drug particles to collide with the metal inner wall and the tuning fork, and the collision force is greater, crushing The effect is better; the high-speed airflow carrying the drug particles is staggered through the nozzles, making the movement of the drug particles more disordered, increasing the frequency of collisions, and using low-temperature nitrogen throughout the process to avoid drug oxidation and heat damage, and at the same time embrittle the raw material particles It can improve the crushing degree; the tuning fork will not produce sound waves of various frequencies after being collided, which can improve the Brownian motion of the decoction pieces powder, weaken the bonding phenomenon, and further improve the crushing effect.

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
