Abstract
The invention discloses a normal temperature preparation method of superfine asthma treatment powder, which comprises the following steps of: firstly, selecting Chinese medicinal herbs comprising white mulberry rootbark, fried bitter apricot seed, radish seed, pepperweed seed, fructus perillae, codonopsis pilosula, rhizoma atractylodis macrocephalae, caulis aristolochiae manshuriensis, rheum officinale, radix curcumae, scutellaria baicalensis and cape jasmine according to proportion; crushing five Chinese herbal medicines comprising the fried bitter apricot seed, the radish seed, the pepperweed seed, the fructus perillae and the cape jasmine at normal temperature and extracting oil components; crushing other medicines into rough powder; crushing the rough powder, entering a special two-way airflow screening machine by wind for screening by using a sieve in 500 meshes to obtain powder with the particle diameter of smaller than or equal to 25 microns for being delivered into a cyclone collector for collecting by airflow generated by a draught fan; collecting powder which is not screened by the sieve in 500 meshes through a hopper and delivering the powder into a rod mill through a pipeline for carrying out circulation crushing again; and fully and uniformly stirring the superfine powder of the collected asthma treatment powder with the extracted medicine oil components to obtain the superfine asthma treatment powder finished product. The invention has the advantages of having the finished medicament particle diameter of smaller than or equal to 25 microns, improving the cell wall breaking rate and bioavailability, strengthening the pharmacological effect and saving Chinese medicinal herbs.
Description
Technical field
The present invention relates to the veterinary drug preparation field, especially relate to superfine powder ding chuan san, powder for curing asthma normal temperature preparation method; The invention still further relates to the special-purpose two-way airflow screening machine that is used for this method.
Background technology
Chinese herbal medicine is the culture rarity of China, first Shennong's Herbal that the works relevant with natural drug is China in the world, Chinese herbal medicine is carrying out having the incomparable superiority of other chemical synthetic drugs aspect the prevention and treatment of diseases: safe, toxic and side effects is little, effective ingredient is many, hazard residue is few, action target spot is many, can bring into play combined effect, be difficult for producing drug resistance, scalable immunity of organisms, enhancing body resistance against diseases in anti-bacteria and anti-virus.More and more emphasize food safety in the our times various countries, call under green, the ecological overall background, apply prevention and the control that herbal medicine carries out Animal diseases and be of great practical significance.
The ding chuan san, powder for curing asthma that is applied to poultry at present is the powder of coarse powder, there are deficiencies such as dosage is big, dosage form thick, appearance poor, effective ingredient can not fully discharge, bioavailability is low, Chinese medicine quality and clinical therapeutic efficacy have been had a strong impact on, and can not with pellet uniform mixing, the defectives such as use of can not directly drinking water.
The broken technology of Chinese medicine ultra-fine powder is renewal and the development to traditional crushing technology; it had both kept the advantage of Chinese medicine technology of preparing; injected new vitality for the modern production of Chinese medicine again; have a extensive future, but remain in actual production in some problems and a difficult problem: (1) production efficiency is low, the power consumption height is the principal element of restriction Chinese medicine ultra-fine powder large-scale production for animals.Rod mill is in traditional closed circuit method crushing process, when most of material has reached fineness requirement, always there is the small part coarse powder to be mixed in wherein, make this part coarse powder further be crushed to the granularity that requires need prolong the pulverizing time significantly, make crush efficiency reduce, power consumption significantly increases; (2) it is poor that there are the material particular diameter uniformity after the classification in selecting crude drugs with winnower classification and grading wheel classification, influenced the quality of production of herbal medicine compound recipe superfine powder greatly, especially when being applied to the use of animal drinking-water, because a small amount of not existence of breaking cellular wall cell is difficult to reach instructions for use.(3) traditional one-way gas flow is sieved, because Chinese medicine is when carrying out micronizing, along with reducing of particle diameter, material particles surface area and surface energy increase, adsorptivity increases, and mobile variation easily is gathered into bulky grain etc. and causes the sieve classification of crossing that surpasses 200 order fineness medicated powder to be difficult to carry out.The existence of above-mentioned factor has had a strong impact on standardization, the large-scale production of herbal medicine superfine powder, and popularization on veterinary clinic and use.
Summary of the invention
The object of the invention is to provide a kind of rapid-action, good effect, bioavailability height, superfine powder ding chuan san, powder for curing asthma normal temperature preparation method that the clinical application amount is few.
Another purpose of the present invention is to provide a kind of special-purpose two-way airflow screening machine that is applied to superfine powder ding chuan san, powder for curing asthma normal temperature preparation method.
Superfine powder ding chuan san, powder for curing asthma normal temperature preparation method of the present invention comprises the steps:
