中药超细粉碎机怎样粉碎才能达到药效?

中药粉碎主要是借机械力将大块的固体药材粉碎成适宜程度的碎块或细粉的操作过程。也可借助其它方法将固体药材碎成微粉的程度,如低温粉碎,就是借助待粉碎物料在低温状态下的境性,而进行粉碎的一种方法。如锤击式粉碎,锤击式粉碎机它利用T形锤高速旋转产生离心力,使物料受到冲击、剪切、磨擦等综合作用得以粉碎。其粒径可达80-200将粉碎后的粉末在孔径上自上而下逐渐减小分级筛上进行分离,在振功作用下.粉木不断通过筛孔进入到下一级直到被筛孔截留,停留在相应筛上后不同粒径的混合粉末被截留在不同目数的筛上,得以分离,将粒径与筛径上物料重量差进行绘图,得到物料粒度特性曲线图。粒度特性曲线可以反映粉碎效果。衡量粉末的均匀性。
The crushing of traditional Chinese medicine is mainly a process of crushing large solid medicinal materials into appropriate degree of crushing or fine crushing by mechanical force. Other methods can also be used to crush solid medicinal materials into micro-powder, such as low-temperature crushing, which is a method of crushing with the help of the environment of the material to be crushed at low temperature. For example, hammer crusher, hammer crusher, which uses T-hammer high-speed rotation to produce centrifugal force, so that materials are impacted, shear, friction and other comprehensive effects can be crushed. Its particle size can reach 80-200, and the crushed powder can be separated on the grading sieve, which gradually decreases from top to bottom in pore size. Under the action of vibration work, the powder wood continuously enters the next stage through the sieve hole until it is intercepted by the sieve hole. After staying on the corresponding sieve, the mixed powder with different particle sizes is intercepted on the sieve of different meshes, and the particles can be separated. The difference of material weight between diameter and sieve diameter is plotted, and the curve of material particle size characteristics is obtained. The particle size characteristic curve can reflect the grinding effect. Measure the uniformity of powder.
中药粉碎的目的主要是为了更好应用在中药生物工程与制药工程中增加药物的表面积,从而促进药物的溶解与吸收,提高药物的生物利用度便于适应多种给药途径的应用,便于药物中有效物质的侵出或溶出,为制备各种剂型提供原科,如散剂、冲剂、丸剂、片剂等剂型都褥用纫粉和颗粒成型,也便于调剂和服用。
The main purpose of crushing Chinese medicines is to increase the surface area of medicines in the bioengineering and pharmaceutical engineering of Chinese medicines, so as to promote the dissolution and absorption of medicines, improve the bioavailability of medicines, facilitate the application of multiple drug delivery routes, facilitate the invasion or dissolution of effective substances in medicines, and extract various dosage forms for the preparation of medicines. Donors, such as powder, granules, pills, tablets and other formulations, are made of sewing powder and granules for bedding, which are also convenient for dispensing and taking.
中药超细粉碎机
中药超细粉碎机利用活动齿盘和固定齿盘间的相对运动,使被粉碎物料经齿冲击,摩擦及物料彼此间的冲击而获得粉碎,粉碎好的物料经旋转离心机和风机的引力,进入旋风分离器出料,然后经关风机,粉尘进入脉冲除尘箱,通过过滤筒和回收,粉碎细度用筛网调节。整机按GMP标准设计,全部用不锈钢材料制作,生产过程中无粉尘飞扬。
The ultra-fine crusher of traditional Chinese medicine makes use of the relative motion between the movable and fixed tooth discs to crush the crushed material through the impact of teeth, friction and impact between the materials. The crushed material is pulled into the cyclone separator and discharged by the rotating centrifuge and the fan, and then the dust is turned off and entered into the pulse dedusting box. Through the filter cartridge and recovery, the grinding fineness is adjusted by screen. The whole machine is designed according to GMP standard. It is made of stainless steel. There is no dust in the production process.
中药超细粉碎机在粉碎过程中不会产生局部过热现象,甚至可在低温状态下进行粉碎,速度快,瞬间即可完成,因而较大限度地保留粉体的生物活性成分,以利于制成所需的高质量产品。由于采用超音速气流粉碎,其在原料上力的分布相当均匀。分级系统的设置,既严格限制了大颗粒,有避免出现过碎,得到粒径分布均匀的超细粉,同时很大程度上增加了微粉的比表面积,使吸附性、溶解性等亦相应增大。物体经超微中药粉碎机粉碎后,近纳米细粒径的超细粉一般可直接用于制剂生产,而常规粉碎的产物仍需要一些中间环节,才能达到直接用语生产的要求这样很可能造成原料浪费。
The ultra-fine crusher of traditional Chinese medicine will not produce local overheating in the crushing process. It can even be crushed at low temperature. The crushing speed is fast and can be completed in an instant. Therefore, the bioactive ingredients of the powder can be retained to a great extent to facilitate the production of the required high-quality products. Because of supersonic airflow pulverization, the force distribution on raw materials is fairly uniform. The setting of classification system not only strictly restricts the large particles, avoids the occurrence of over-fragmentation, and obtains ultra-fine powder with uniform particle size distribution, but also greatly increases the specific surface area of micro-powder, so as to increase the adsorbability and solubility of micro-powder accordingly. Ultra-fine powder with near nanometer particle size can be directly used in preparation production after the object is crushed by ultra-fine crusher of traditional Chinese medicine. However, the products of conventional crushing still need some intermediate links to meet the requirements of direct terminology production, which may result in waste of raw materials.
