Embodiment Construction
[0034] Such as figure 1 , 2 Shown, the normal temperature preparation method of superfine powder pulsatilla powder of the present invention, comprises the following steps:
[0035] The first step is to wash and dry the decoction pieces of the Chinese herbal medicine Pulsatilla pulsatillae until the water content is ≤10%;
[0036] The second step is to pulverize the cut traditional Chinese medicine at 20°C to 25°C to obtain a coarse powder with a particle size of 65-100 mesh;
[0037]The third step, at first turn on the powder conveying fan 15, the induced draft fan 5, the blower 11, and the driving motor 8. The blowing pressure of the powder conveying fan 15 is 24kpa, and the blowing volume is 150m 3 / h; the induced air pressure of the induced draft fan 5 is 1000pa, and the induced air volume is 3000m 3 / h; the blast pressure of blower 11 is 33kpa, and the blast volume is 320m 3 / h; the rotational speed of the drive motor 8 is 155 rpm.
[0038] 1. After the coarse powder...

Abstract
The invention discloses a normal-temperature preparation method for ultra-micro fine Chinese pulsatilla powder. The method comprises the following steps of: firstly, cleaning traditional Chinese medicine Chinese pulsatilla decoction pieces, and drying the decoction pieces until the water content is less than or equal to 10 percent; crushing cut traditional Chinese medicine at normal temperature to obtain crude powder of which the granularity is 60 to 100 meshes; after milling the obtained crude powder in a rod mill, blowing the powder into a special bidirectional airflow sieving machine, sieving the powder with a 500-mesh sieve, blowing the obtained powder of which the particle size is less than or equal to 25 mum through airflow generated by a draught fan into a cyclone collector, and collecting the powder to obtain the finished product of the ultra-micro fine Chinese pulsatilla powder; and collecting the powder which does not pass through the 500-mesh sieve through a hopper, and conveying the powder through a pipe into the rod mill to be recovered and crushed. The method has the advantages that: the whole preparation process is performed at normal temperature without low temperature or other special additional conditions, the particle size of the prepared medicament is less than or equal to 25 mum, the cell wall-broken rate and the bioavailability are greatly improved, and the pharmacological effect is enhanced. Due to the adoption of the bidirectional airflow sieving machine, the preparation process of the ultra-micro fine Chinese pulsatilla powder is greatly simplified.
Description
technical field [0001] The invention relates to the field of veterinary drug preparations, in particular to a normal-temperature preparation method for ultrafine powder Pulsatillae Radix Powder; the invention also relates to a special two-way airflow sieving machine used in the method. Background technique [0002] China is a big pig raising country. With the continuous progress and development of pig farming, the survival rate and disease resistance of piglets have been greatly improved. With the change of people's consumption concept, the pursuit of green and pollution-free food has become a consumption fashion. However, if the use of antibiotics in piglet feed is reduced, it will have a serious impact on the production performance, disease resistance and survival rate of piglets. Therefore, it is necessary to seek a drug with low toxicity, no impact on human health, and the same effect as antibiotics to replace the use of antibiotics, and under actual production conditio...
