Analysis of pulverization characteristics of plant fiber (Chinese herbal medicine) and application of machine type

In daily production and work, the comminution of plant fiber materials (typically representative of Chinese medicinal materials) is a common problem. The characteristics of the plant itself determine that the crushing of the material has certain peculiarities and skill, and the fineness has different requirements. The selected models are also different. The following is a brief analysis and introduction.

Plants generally consist of roots, stems, leaves, flowers, fruits, etc., and the properties of each part are not the same.

Roots, stems and leaves generally play a role in storage, transport, fixation, etc., so the prominent features of these parts are more fibrous. For example, common in 37% of Chinese herbal root or roots, such as ginseng, licorice, astragalus, angelica; common herbs ephedra stem, twig, mulberry, magnolia bark, Eucommia, Gastrodia, incense Etc. Common leaf medicinal materials include Daqingye, Mulberry, Suye, Senna, and Ai Ye .

The above data shows that the big problem of plant crushing is that the fiber is very strong. So, what is the good way to smash the fibrous material? According to our many years of practical experience, it is “grinding, shearing and impacting”. That is, in the pulverization process, the long fibers are first made into short fibers by shearing force, and then the short fibers are pulverized into powder by "grinding and impacting force", which is determined by the characteristics of the plants.

At present, there are many types of shredders on the market, the principle and characteristics are different, and each has its own merits, and the applicable fields are also different. If you choose to crush a plant (such as Chinese herbal medicine) crusher, you should start with this feature of plant fiber.

Take the crusher that our company produces and manages to meet this demand.

For example, if the fineness of the plant you need to crush is not large under 120 mesh, you can choose such as " 6202 small crusher, RT-04 small crusher and KC-04 series small crusher". This type of pulverizer is characterized by "shearing and impacting", and the pulverizing capacity ranges from tens of grams to several hundred grams per gram. This type of pulverizer is usually mixed with coarse and fine powder after crushing. Of course, it will not be too thick. It does not affect the use. It is generally suitable for use in colleges or research institutes, hospital pharmacies, pharmacies, Traditional Chinese medicine clinics and other units do general smashing.

Another type of pulverizer is in the form of "grinding, shearing". The model has " RT-34\\RT-20 continuous feeding mill " and so on. It utilizes the interaction between the tamper and the grinding tile, that is, grinding and cutting, and is equipped with mesh filtering, so the pulverizing effect of the pulverizer is better than that of the small high-speed pulverizer, the output is large, and there is no need to go through the sieving. .

The above pulverizers belong to the category of ordinary comminution of plant fibers. Judging from the current situation of scientific research and production, the demand for ultrafine pulverization is rising, and the ultrafine pulverizer is used. Our superfine shredders are divided into two levels. The first is the range of 200-300 mesh. Generally, the "FDV small laboratory superfine grinder" model is used. If you need higher fineness, such as 800 mesh or even thousands of purposes, you should use " 710 small super Micro-grinder or 400 -type, 510 medium-sized superfine pulverizer". Their average fineness is above 800 mesh, which can completely meet the needs of cell wall breaking.

So what is the second most difficult point of plant crushing? It is a seed, fruit and flower with many oily, mucous, and polysaccharide components. Common such as scorpion, raw land, cypress kernel and so on. When such materials are pulverized, they must be subjected to a certain pretreatment and cannot be directly pulverized. For example, drying treatment, and then mixing and pulverizing, that is, incorporating some dry materials to absorb the viscosity and oiliness, etc., while the pulverizer is equipped with a low-temperature device, such as water cooling, liquid nitrogen cooling, etc., to avoid the increase of temperature to cause bonding phenomenon. .

The above is based on some of our years of experience in the crushing practice. If you need more detailed product information and smashing, please visit us or communicate with us.
