Among the many raw materials pulverized by laboratory pulverizers, traditional Chinese medicines also face many problems due to their complex nature
.
Today, we start from the nature of the medicinal material itself, seek answers through questions, and provide reference for laboratory grinders, especially small laboratory grinders, to improve the efficiency of traditional Chinese medicine grinding
.
First of all, the common problems faced by Chinese herbal medicine crushing are as follows: 1.
It is not easy to be stressed - most of the Chinese herbal medicines are plants, and their properties are not diverse.
A considerable part is fibrous and has a light specific gravity.
The hammer head and blade are difficult to crush, because the raw material is not easy to bear force at this time, and the crushing ability is greatly reduced without the force point, and users often have the feeling of "hammering cotton"
.
2.
It is easy to heat up and generate high temperature - most Chinese herbal medicines have active ingredients.
During the crushing process, there are higher requirements for temperature.
If you blindly pursue the impact force brought by high speed, the temperature of the crushing bin and raw materials is often too high, resulting in Loss of efficacy
.
3.
The crushing fineness does not meet the requirements - with the implementation of the new pharmacopoeia, the laboratory testing generally requires the fineness of medicinal powder to pass the No.
4 or No.
5 sieve.
This requirement can be easily achieved in the crushing of brittle raw materials.
But when faced with fibrous Chinese medicines such as licorice, astragalus, etc.
, the ordinary knife-type small steel mill or grinder becomes powerless
.
4.
The volume and cost of the equipment restrict the large-scale promotion in laboratories and testing units - the current traditional Chinese medicine pulverizer or the entire pulverizer industry has a basic industry feature.
The higher the pulverization fineness of the product, the higher the equipment price and the The faster the crushing speed is, the larger the output, the more expensive the equipment is.
This is also the reason why the small high-speed pulverizer is mainly used in laboratory testing at present.
It ranges from a few hundred yuan to several thousand yuan, but this kind of machine cannot solve the crushing of special materials, and it has a tasteless feeling
.
The starting price of imported models, which are often tens of thousands of yuan, is a bit high for ordinary customers
.
In response to the above problems, Benchen Technology has launched a series of laboratory traditional Chinese medicine pulverizers based on years of experience in Taiwan, China's pulverizers, combined with domestic technology and raw materials.
The temperature, method, compact size and weight ensure the convenience of use, and the price of several thousand yuan to ten thousand yuan guarantees the cost-effectiveness.
Today we will explain to you through the actual test machine crushing situation
.
The raw materials of traditional Chinese medicine we choose this time are the common fibrous traditional Chinese medicine licorice and the seed medicinal material cassia seed.
The feeding requirements of the machine are carried out by direct feeding without pretreatment.
After our crushing and fineness test, the granularity of licorice can reach: D50 200 mesh, D90 120 mesh, Cassia: D90 No.
5 sieve, the above fineness is The data obtained by the primary crushing will be further improved if the secondary crushing fineness and pass rate are carried out, but the current crushing fineness can already meet the fineness required by the new pharmacopoeia
.
The BC3-2 air-induced ultrafine pulverizer adopts a no-screen air-selection structure.
The advantage of this structure is that the fineness is improved obviously and the uniformity is very good.
The crushing of cassia seeds shows the advantages of this machine.
The outer skin is tough, and the raw material contains a certain amount of oil.
The air-selected material has no screen and does not block the screen, so it is more suitable for the crushing of such raw materials
.
The laboratory traditional Chinese medicine pulverizer is not only this one machine, the same series of machines include water-cooled type, pulse type, etc.
The rich configuration is more practical when facing many raw materials
.
The advantages and disadvantages of the machine and the complexity of the raw materials give us greater motivation to improve our traditional Chinese medicine grinder products to adapt to more raw material grinding requirements, and hope to communicate with more traditional Chinese medicine decoction pieces factories, inspection and testing institutions Collaborate to improve the performance of our laboratory grinders
