Normal-temperature ultrafine argy wormwood leaf powder preparation method

Abstract

The invention discloses a normal-temperature ultrafine argy wormwood leaf powder preparation method. Argy wormwood leaves are first washed, aired, cut into sections and dried until the moisture content is less than or equal to 10 percent; the cut argy wormwood leaves are milled under the normal temperature, so that coarse powder, the grain size of which is 60 to 89 meshes, is obtained; the obtained coarse powder is put into a rod mill, milled and then sent into a special two-way air flow screening machine by wind to pass through a 500-mesh screen, screened powder, the grain size of which is less than or equal to 25 micrometers, is conveyed into a cyclone collector by the air flow produced by a draught fan and collected, so that finished ultrafine argy wormwood leaf powder product is obtained; and the powder which does not pass through the 500-mesh screen is collected via a funnel, conveyed into the rod mill via a pipeline and milled again. The invention has the advantages that: the whole preparation process is carried out under the normal temperature, and does not need low temperature or special additional conditions; the grain size of the finished argy wormwood leaf product is less than or equal to 26 micrometers, so that the cell wall-breaking rate and the bioavailability are increased, the two-way air flow screening machine can simplify the preparation process, and the purposes of quality standard controllability and industrial mass production are achieved.

Description

technical field [0001] The invention relates to a veterinary drug additive, in particular to a normal-temperature preparation method of superfine powdered mugwort leaves; the invention also relates to a special two-way airflow screening machine used in the method. Background technique [0002] Chinese herbal medicine additives have the characteristics and advantages of naturalness, multifunctionality, and no toxic and side effects. They can improve the growth performance of animals and improve the quality of animal products. Pharmacological studies on the growth performance of Chinese medicines have shown that many Chinese medicines have the ability to promote animal growth. However, traditional Chinese medicine has the disadvantages of large dosage, thick dosage form, poor appearance, inability to fully release active ingredients, and low bioavailability, which affects the quality of traditional Chinese medicine and clinical health care effects. [0003] Artemisia argyi was...
