Room-temperature preparation method of ultramicro powder pomegranate rind pulvis and special two-way airflow screening machine thereof

Abstract

The invention discloses a room-temperature preparation method of ultramicro powder pomegranate rind pulvis. The preparation method comprises the following steps: firstly, naturally airing or drying Chinese herbal medicine pomegranate rind pieces ready for decoction until the moisture content of the pieces ready for decoction is less than or equal to 10%; smashing dried pomegranate rind at room temperature to obtain coarse powder with the granularity of 60-80 meshes; putting the obtained coarse powder in a rod mill for smashing, then sending the smashed powder to a special two-way airflow screening machine by air to screen by a 500-meshed screen, conveying screened powder with the particle size less than or equal to 25 micrometers to a whirlwind collector by airflow generated by a draught fan, and collecting to obtain the finished product of the ultramicro powder pomegranate rind pulvis; and collecting powder which is not screened by the 500-meshed screen by a funnel and conveying the collected powder to the rod mill for circular smashing again. The method has the advantages that the whole preparation process is performed at room temperature; the particle size of prepared finished product medicament is less than or equal to 25 micrometers, thus greatly improving cell wall-broken ratio and bioavailability; and the two-way airflow screening machine used in the invention simplifies the preparation process of the ultramicro powder pomegranate rind pulvis, thus realizing the purpose of controllable quality standard of traditional Chinese medicine pulvis.

Description

technical field [0001] The invention relates to the field of veterinary drug preparations, in particular to a normal-temperature preparation method of superfine powder pomegranate peel powder; the invention also relates to a special two-way airflow sieving machine used in the method. Background technique [0002] It is an urgent need to expand the export of livestock products and improve product quality by using Chinese herbal medicine additives to prevent and control diseases, replace and reduce the dosage of chemicals and antibiotics, and produce pollution-free "green livestock and poultry products". Using different usage methods and formulas for breeding can improve the body's resistance, promote growth, reduce the disadvantages of drug residues, and have the effect of "treating both symptoms and root causes", which is worth popularizing. How to prevent and control epidemic diseases, improve the health level of livestock and poultry, so as to prevent and cure diseases, pr...
