Embodiment 1

[0025] An embodiment of the present invention provides a grinding method for producing finely ground medicinal materials, comprising the following steps:

[0026] Sp1: The raw medicinal materials are sorted and cleaned and dried in a hot air circulation oven for later use. The drying rate of the raw medicinal materials is 8%;

[0027] Sp2: Put the dried raw medicinal materials into an impact mill for coarse crushing for 30 seconds and pass through a 40-mesh sieve;

[0028] Sp3: In step 2, the crude medicinal materials that have been coarsely screened are placed in the pre-cooling chamber for 4 minutes, until the temperature reaches -35°C, and then the pre-cooled raw medicinal materials are quickly frozen to -90°C within 30 seconds in the freezer;

[0029] Sp4: Put the cooled and embrittled raw medicinal materials in Step 3 into the ultra-low temperature pulverizer (filled with liquid nitrogen in advance), and pulverize under the condition of ultra-low temperature maintained at...

Embodiment 2

[0032] An embodiment of the present invention provides a grinding method for producing finely ground medicinal materials, comprising the following steps:

[0033] Sp1: The raw medicinal materials are sorted and cleaned and dried in a hot air circulation oven for later use. The drying rate of the raw medicinal materials is 6%;

[0034] Sp2: Put the dried raw medicinal materials into an impact mill for coarse crushing for 30 seconds and pass through a 40-mesh sieve;

[0035] Sp3: In step 2, the crude medicinal materials that have been coarsely screened are put into the pre-cooling chamber for 5 minutes to pre-cool until the temperature reaches -35°C, and then the pre-cooled raw medicinal materials are put into the freezer for 30 seconds and quickly frozen to -90°C;

[0036] Sp4: The raw medicinal materials cooled and embrittled in step 3 are put into the MCM550 ultra-low temperature pulverizer (filled with liquid nitrogen in advance). The input particle size is ≤2cm, the total ...

Embodiment 3

[0039] An embodiment of the present invention provides a grinding method for producing finely ground medicinal materials, comprising the following steps:

[0040] Sp1: The raw medicinal materials are sorted and cleaned and dried in a hot air circulation oven for later use. The drying rate of the raw medicinal materials is 10%;

[0041] Sp2: Put the dried raw medicinal materials into an impact mill for coarse crushing for 30 seconds and pass through a 40-mesh sieve;

[0042] Sp3: In step 2, the crude medicinal materials that have been coarsely screened are put into the pre-cooling chamber for 5 minutes to pre-cool until the temperature reaches -35°C, and then the pre-cooled raw medicinal materials are put into the freezer for 30 seconds and quickly frozen to -90°C;

[0043] Sp4: The raw medicinal materials cooled and embrittled in step 3 are put into the MCM550 ultra-low temperature pulverizer (filled with liquid nitrogen in advance). The input particle size is ≤2cm, the total...

Abstract

The invention provides a grinding method for producing fine ground medicinal materials and relates to the technical field of medicinal material smashing. The grinding method for producing the fine ground medicinal materials includes the following steps that raw material medicinal materials are picked and chosen, and cleaned to enter a drying processing device to be dried for standby use; the raw material medicinal materials after being dried enter an impacting type smashing unit to be smashed for 30 s and pass through a 40-mesh screen net; secondly; the raw material medicinal materials after rough screening enter a pre-cooling cavity to be pre-cooled for 3-5 min, till the temperature reaches -35 DEG C, the pre-cooled raw material medicinal materials enter a freezing bin to be fast frozen to -90 DEG C within 30 s; thirdly, the brittle raw material medicinal materials after being cooled enter an ultra low temperature smashing machine (filled with liquid nitrogen in advance), and are smashed under the ultra low temperature condition that the temperature is maintained at -90 DEG C; and fourthly, the materials after being smashed enter a cyclone separator to be separated, solid powder materials after being screened enter a storing tank, and finished products are obtained after packaging. The smashing effect is good, the operation cost of production can be lowered, meanwhile, losingof effective components can be effectively prevented, and the quality of the products is improved.

Description

technical field [0001] The invention relates to the technical field of crushing medicinal materials, in particular to a grinding method for producing finely ground medicinal materials. Background technique [0002] The rapid development of the Chinese pharmaceutical market has made traditional Chinese medicine preparations have higher and higher requirements for the fineness of pharmaceutical powders. The existing techniques for preparing ultrafine powders of traditional Chinese medicine can be divided into physical methods and chemical methods. Some nano-scale Chinese medicine reagents produced by chemical methods have been released, but chemical methods have changed the components and properties of medicines, and cannot be directly faced. For natural raw materials, and the utilization rate is not high, so through the direct crushing of traditional Chinese medicine to make it ultra-fine has become a development trend. At present, there are many technologies for ultra-fine g...
