Problems solved by technology
At present, Wupi powder used in livestock and poultry is mostly coarsely crushed powder, which has the disadvantages of large dose, coarse dosage form, poor appearance, etc., the active ingredients cannot be fully released, and the bioavailability is low, which seriously affects the quality of traditional Chinese medicine and clinical treatment effect. Moreover, it cannot be evenly mixed with pellet feed, and cannot be directly added to drinking water for use.
[0004] Traditional Chinese medicine ultrafine pulverization technology is an update and development of traditional pulverization technology. It not only retains the advantages of traditional Chinese medicine preparation technology, but also injects new vitality into the modern production of Chinese medicine. It has broad application prospects, but there are still some problems in actual production. Problems and problems: (1) Low production efficiency and high energy consumption are the main factors restricting the large-scale production of veterinary traditional Chinese medicine ultrafine powder

Embodiment Construction
[0060] Such as figure 1 , 2 Shown, the normal temperature preparation method of superfine powder Wupi powder of the present invention, comprises the following steps:
[0061] The first step is to select decoction pieces of mulberry bark, tangerine peel, big belly bark, ginger bark, and poria bark, and dry them naturally or until the moisture content is ≤10%;
[0062] In the second step, the above raw materials are respectively pulverized at a temperature of 20° C. to 25° C. to obtain coarse powder of traditional Chinese medicine with a particle size of 60 to 80 meshes;
[0063] The 3rd step, above-mentioned crude drug coarse powder is mixed according to the weight portion ratio of Cortex Mori: Tangerine Peel: Dabupi: Jiangpi: Poria Cocos=2:2:2:1:2;
[0064] In the fourth step, first turn on the powder conveying fan 15, the induced draft fan 5, the blower 11, and the drive motor 8. The blowing pressure of the powder conveying fan 15 is 24kpa, and the blowing volume is 150m ...

Abstract
The invention discloses a constant-temperature preparation method for submicron powder Wupi powder, comprising the following steps of: drying and smashing white mulberry root bark, pericarpium citri reticulatae, pericarpium arecae, ginger peel and poria peel cortex poriae crude drugs slice processed for decoction to obtain coarse powder; putting the coarse powder into a rod mill to be smashed at the following ratio: 2 parts of white mulberry root bark, 2 parts of pericarpium citri reticulatae, 2 parts of pericarpium arecae, 1 part of ginger peel and 2 parts of poria peel cortex poriae; sending into a special bidirectional airflow screening machine by wind to be screened by using a screen of 50 meshes; conveying a powder material of which the particle diameter is less than or equal to 25 micrometers into a cyclone material collector by airflow generated by an induced draft fan to be collected to obtain the finished product of the submicron powder Wupi powder; collecting the powder material which is not screened by using the screen of 500 meshes; and conveying into the rod mill via a pipeline to be cyclically smashed again. The constant-temperature preparation method for the submicron powder Wupi powder has the advantage that the whole preparation process is carried out at constant temperature, no low temperature or special additional conditions are required, the particle diameter of the finished product medicine is less than or equal to 25 micrometers, and the cell-wall breaking ratio and the bioavailability are greatly improved. According to the special bidirectional airflow screening machine used in the room-temperature preparation method, the preparation technology of the submicron powder Wupi powder is simplified.
Description
technical field [0001] The invention relates to the field of veterinary drug preparations, in particular to a method for preparing superfine powder Wupi powder at normal temperature; the invention also relates to a special two-way airflow sieving machine used in the method. Background technique [0002] Chinese herbal medicine has incomparable advantages over other chemically synthesized drugs in the prevention and treatment of diseases: high safety, less toxic and side effects, more active ingredients, less harmful residues, more targets of action, can play a combined effect, and is not easy to produce drug resistance It can regulate the body's immunity and enhance the body's disease resistance while antibacterial and antiviral. Under the background that countries around the world are increasingly emphasizing food safety and calling for green and ecological conditions, it is of great practical significance to promote the application of traditional Chinese veterinary drugs f...
