Analysis of the characteristics of the comminution of plant fibers (Chinese medicinal materials) and the application of the machine

In daily production and work, the pulverization of plant fiber materials (typical representative of traditional Chinese Medicine) is a common problem The characteristics of plants determine that the crushing of this kind of materials has certain particularity and technicality, and the fineness has different requirements, and the selected models are also different Here are some brief analysis and introduction Plants are generally composed of roots, stems, leaves, flowers, fruits and other parts, each of which has different properties Roots, stems and leaves generally play the role of storage, transportation and fixation, so the prominent feature of these parts is strong fiber For example, 37% of the common herbal medicines are roots or rhizomes, such as ginseng, liquorice, astragalus, angelica, etc.; the common rhizomes are ephedra, cinnamon twigs, mulberry twigs, Magnolia officinalis, eucommia, Gastrodia elata, aloe, etc.; the common leaves are Folium Isatidis, mulberry leaves, Soviet leaves, senna leaves, mugwort leaves, etc The above data show that the major problem of plant crushing is that the fiber is very strong So, what is a good way to crush Zui? According to our years of practical experience, it is "grinding, shearing and impact" That is to say, in the process of crushing, the long fiber is first made into short fiber by shear force, and then the short fiber is crushed into powder by "grinding and impact force", which is determined by the characteristics of plants At present, there are many kinds of pulverizers in the market, with different principles and characteristics, and different application fields If you choose to crush plant (such as Chinese herbal medicine) crusher, you should start with this feature of plant fiber Take our company's production and operation of the crusher for example, can meet this demand For example, when the fineness of the plant you need to crush is less than 120 mesh, you can choose such as "6202 small crusher, rt-04 small crusher and kc-04 series small crusher" This kind of crusher is characterized by "shearing and impact", with crushing capacity ranging from tens to hundreds of grams each time This type of pulverizer is generally mixed with coarse and fine powder after pulverizing, of course, the coarse one is not too much In order not to affect the use, Zui is better than screening, and generally suitable for general ordinary powder crushing in Colleges and universities or scientific research unit laboratories, hospital pharmacies, pharmacies, TCM clinics and other units Another type of crusher is in the form of "grinding and shearing" The model has "rt-34 \ \ rt-20 continuous feeding pulverizer" and so on It makes use of the interaction between the hammer and the grinding tile, that is, grinding and cutting, and is equipped with a screen filter, so the crushing effect of this kind of crusher is better than that of the small high-speed crusher, and the output is large, and there is no need to go to the screen again All of the above pulverizers belong to the category of ordinary crushing of plant fiber According to the current situation of scientific research and production, the demand of ultra-fine pulverization is increasing, so it is necessary to use ultra-fine pulverizer Our ultra micro pulverizer is divided into two levels First of all, in the range of 200-300 mesh, the model of "FDV small laboratory ultra-fine crusher" is generally used; if higher fineness is needed, such as 800 mesh or even thousands of mesh, the model of "710 small ultra-fine crusher or 400, 510 medium and large ultra-fine crusher" will be used Their fineness is above 800 mesh on average, which can meet the demand of cell wall breaking So what's the second difficulty of crushing plants? It is the seeds, fruits and flowers with more oil, mucilaginous, polysaccharide and other components Common such as wolfberry, raw and ripe ground, cypress kernel and so on Generally, this kind of material should be treated before crushing, and it can't be crushed directly For example, drying treatment, and then mixing and crushing, that is, adding some dry materials to absorb its viscosity and oil, etc at the same time, the crusher is equipped with low-temperature devices, such as water cooling, liquid nitrogen cooling, etc., to avoid the phenomenon of adhesion caused by the rise of temperature The above is based on our many years of crushing practice summary of some experience If you need to know more detailed product information and crushing information, please log in or communicate with us Label: plant pulverizer, traditional Chinese medicine pulverizer, ultra micro pulverizer, small high-speed pulverizer, experimental ultra micro pulverizer (the above copyright is owned by Beijing chuangtonghe Technology Development Co., Ltd., no Reprint)
