As micro - cellular level pulverizing Break through the dynamic (plant) species medicinal cell wall (membrane), to raise the biological utilization of comminution degree called Chinese cellular level pulverizing. The vast majority of varieties of traditional Chinese medicinal materials from animals (plant), dynamic (planting) physical medicine is composed of a variety of functions of the cell, the cell by cell wall, cell membrane, cytoplasm, nucleus composition, particle size is generally in the 10 μ m to 100 μ m, and the effective components in medicinal exists mainly in the cytoplasm, the nucleus. Intact cells under the condition of effective ingredients, only through the cell membrane, cell wall release can be used. Cell membrane integrity, cell wall on the release of effective components forming resistance, increasing of the number of cells and cell clusters within the resistance with increased rapidly. The effective components in medicinal mainly between the cytoplasm and the nucleus cells -. The cell wall (membrane) inward resistance and cell pellets (powder) dual influence of condensation resistance, medicinal components to release and metabolism or intestinal absorption, this is the important reason of using traditional Chinese medicine, curative effect not obvious dose. To eliminate this resistance should adopt micro comminution, the cells break to make the effective components of cells in direct contact with the solvent. This job is not for the purpose of fineness to fineness, only as a macro examination means, can not express the real situation of medicinal powder. In general cell wall broken rate is high and the fineness finer. Cells were treated with the effective ingredients in broken cell fully exposed (instead of through the cell wall (membrane) release), make the drug more quickly, completely. Drug particles by cellular level pulverizing, are observed only a very small amount of intact cells (see photos). Working principle As micro mechanical superfine crushing equipment is a new fourth generation of vibration mill, is based on the different characteristics of the material, using a number of advanced technology and application of high speed impact force and shear force, so that the material high acceleration by the medium in the grinding barrel impact, notes, extrusion, cutting effect, can achieve the ideal effect of crushing in a very short period of time. The materials are fluidized in the process of crushing, so that every particle has the same stress state, to achieve the precise mix in crushed at the same time (dispersed) effect. After adjusting the acceleration parameters, can be realized in a crushing and grinding for the purpose or precision hybrid (mixed) as the main objective of the work. As micro superfine pulverizer adopts the advanced technology 1, full closed without classification technology: used for preservation of medicinal components full closed mill without screen technology, effectively avoid the effect of composition segregation and loss, caused by dust and pollution of the environment and other phenomena. 2, compressed micro grinding technology: in order to improve the grinding efficiency and effect, using the high-speed impact force and shear force, so that the material by the medium of extrusion, kneading and tear in the grinding barrel, greatly shorten the grinding time, improve the crushing efficiency; at the same time, because the material is fluidized and each particle has the stress state of the same its viscosity, the finished product can form a uniform dispersion and precision composite particles cluster, density increase and improve the bioavailability, improve the micro crushing effect and technology. 3, the dynamic optimization techniques: according to the different characteristics of the material, in order to increase micro grinding efficiency and effect at the same time, the optimal adaptation technology. 4, mechanical and electrical integration technology: the realization of equipment of high performance and high level, reduce artificial dosage, to ensure that the technology is stable and controllable quality of the finished product, avoid and unstable quality, contaminated phenomenon because of too much manual intervention. 5, the comprehensive automation technology: with a single multifunctional automation (FMC flexible), make small batch of drug production as mass production line is as simple as the technology. 6, clean and safe technology: Micro superfine pulverizer series strictly according to GMP standard design and manufacturing, to meet the special requirements of pharmaceutical powder equipment
