Submicron powder bazheng powder normal temperature preparation method and special bidirectional airflow sieving machine thereof

Abstract

The invention discloses a submicron powder bazheng powder normal temperature preparation method, which comprises choosing technical materials of akebiaquinata, dianthus superbus, polygonum aviculare, liquorice, fried jasmine, rheum officinale, juncos communis medicinal slices, soapstone and plantain seed raw materials in proportion; drying and smashing to obtain coarse powder; extracting plantainseed oil in the plantain seed coarse powder to be reserved; evenly mixing the rest of coarse powder and the plantain seed dregs in a rod mill to be smashed to be sent into a special bidirectional airflow sieving machine for 500 sieves to obtain powder materials with the grain diameter equal to or smaller than 25 micrometers; achieving bazheng powder submicron powder by collecting powder materialsconveyed to a cyclone material collector by air airflow generated by an air induced fan; collecting the powder material not sieved for 500 sieves to be conveyed into the rod mill through a pipeline to be smashed repeatedly; and evenly mixing the collected bazheng powder submicron powder and the plantain seed oil to obtain submicron powder bazheng powder end products. The submicron powder bazheng powder normal temperature preparation method has the advantages of performing the whole process at the normal temperature. The special bidirectional airflow sieving machine simplifies preparation process of the submicron powder bazheng powder.

Description

technical field [0001] The invention relates to the field of veterinary drug preparations, in particular to a method for preparing superfine powder Bazheng 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 is a cultural treasure of our country. The first book related to natural medicine in the world is my country's "Shen Nong's Herbal Classic". Chinese herbal medicine has incomparable advantages in the prevention and treatment of diseases: high safety , less toxic and side effects, more active ingredients, less harmful residues, more targets, can play a combined effect, not easy to produce drug resistance, 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 condition...

Problems solved by technology

Bazheng powder currently used in livestock and poultry is mostly coarsely crushed powder, which has the disadvantages of large dose, coarse dosage form, and poor appearance. 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

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
