Problems solved by technology

Chicken coccidia powder currently used to treat chicken coccidiosis 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 and clinical practice of traditional Chinese medicine. Therapeutic effect, and can not be evenly mixed with pellet feed, can not 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
In the traditional closed-circuit crushing process of the rod mill, when most of the materials have reached the fineness requirement, there is always a small part of coarse powder mixed in it, and the crushing time needs to be greatly extended to further crush this part of the coarse powder to the required particle size , so that the crushing efficiency is reduced, and the energy consumption is greatly increased; (2) There is a difference in particle size uniformity of the material after classification in winnowing classification and classifying wheel classification, which greatly affects the production quality of Chinese veterinary drug compound superfine powder, especially in the application of animal When using drinking water, it is difficult to meet the usage requirements due to the existence of a small amount of unbroken cells
(3) In the traditional unidirectional airflow screening, when Chinese medicine is ultrafinely pulverized, as the particle size decreases, the surface area and surface energy of the material particles increase, the adsorption increases, the fluidity becomes poor, and it is easy to aggregate into large particles It is difficult to sieve and classify powders with a fineness of more than 200 mesh

Embodiment Construction

[0069] like figure 1 , 2 As shown, the normal temperature preparation method of superfine powder chicken coccidiosis powder of the present invention comprises the following steps:

[0070] The first step is to select Artemisia annua, Agrimony, Polygonum multiflorum, Pulsatilla, and cinnamon pieces by weight, and dry them naturally or dry to a moisture content of ≤10%;

[0071] The second step is to pulverize the above-mentioned raw materials at a temperature of 20°C to 25°C, respectively, to obtain a coarse powder of traditional Chinese medicine with a particle size of 60 to 80 meshes;

[0072] The 3rd step, above-mentioned crude drug coarse powder is mixed according to Artemisia annua: Agrimony: Polygonum multiflorum: Pulsatilla: Cinnamon=30:5:5:3:2.6 in weight ratio;

[0073] The fourth step is to 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 ...

Abstract

The invention discloses a normal-temperature preparation method for ultrafine coccidia powder. The method comprises the following steps of: selecting decoction pieces of sweet wormwood, hairyvein agrimony, tuber fleeceflower root, Chinese pulsatilla root and cinnamon according to parts by weight, drying and smashing to obtain coarse powder of which the granularity is 80 meshes; putting the obtained coarse powder into a rod mill for smashing, feeding into the special bilateral airflow sieving machine through wind for sieving with a 500-mesh sieve, sieving to obtain power of which the particle diameter is less than or equal to 25 micrometers, conveying the powder which is obtained by sieving into a cyclone aggregator through airflow generated by a draught fan for collecting to obtain finished ultrafine coccidia powder; and collecting powder which is not sieved with the 500-mesh sieve with a funnel, and conveying to the rod mill through a pipeline for smashing circularly once again. The method has the advantages that: the entire preparation process is performed at the normal temperature without low temperature or special additional conditions; the particle diameter of a prepared finished medicament is less than or equal to 25 micrometers, and the cell-wall breaking rate and the biological availability are greatly increased; and due to the adoption of the bilateral airflow sievingmachine, the preparation process of the ultrafine coccidia powder is simplified, and the aim of controlling the quality standard of Chinese medicinal powder is fulfilled.

Description

technical field [0001] The invention relates to the field of veterinary drug preparations, in particular to a method for preparing superfine coccidian powder at normal temperature; the invention also relates to a special two-way airflow screening 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...
