Submicron powder cough powder normal temperature preparation method

Abstract

The invention discloses a submicron powder cough powder normal temperature preparation method, which comprises the following steps that: rhizoma anemarrhenae, bitter orange, herba ephedra, balloon flower, bitter almond, lepidium seeds, cortex mori radicis, dried orange peel, gypsum, peucedanum root, blackberry lily, folium eriobotryae and liquorice are weighed according to proportion, dried and pulverized, and oil in the bitter almond and the lepidium seeds is extracted; the coarse powder and the dregs of the bitter almond and the lepdium seeds are mixed and are placed inside a rod mill to be pulverized, then the mixed powder is blown into a special two-way airflow screen grader to be screened to obtain the powder with the granularity being less than or equal to 25nm, and the powder is conveyed by the airflow produced by a draught fan into a cyclone collector to be collected and to obtain the cough submicron powder; the powder cannot pass through a 500-mesh sieve is collected by a funnel and is conveyed into the rod mill through a pipeline to be circularly pulverized; and the cough submicron powder finished product is obtained by adequately mixing the cough submicron powder and the bitter almond oil and the lepdium seed oil. The preparation method has the advantages that: the entire preparation process is carried out under the normal temperature, and the granularity of the finished product medicine is less than or equal to 25nm; and the two-way airflow screen grader which is utilized in the method can simplify the preparation process of the submicron powder cough powder.
