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.
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.
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.
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.
