Description
Technical field
The present invention relates to the veterinary drug preparation field, especially relate to superfine powder huoxiang zhengqi powder 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
Be applied to the huoxiang zhengqi powder that domestic animal prevents and cures diseases summer at present and mainly contain the powder that ten kinds of traditional Chinese medicines such as Herba Pogostemonis, Folium Perillae, the Radix Angelicae Dahuricae are formed; Have separate in the harmony in the exterior, the effect of regulating QI to expel dampness; Can suppress the intestinal smooth muscle activity; Remove intestinal and smoothly reach spasm, staphylococcus aureus, the first and second type Salmonella paratyphi, dysentery bacterium are had the obvious suppression effect.Used powder exists that dosage is big, dosage form is thick, appearance poor, and effective ingredient can not fully discharge, and bioavailability is low to be waited not enoughly, has had a strong impact on Chinese medicine quality and therapeutic effect.
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 in actual production, remain 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 few 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 is prone to be 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 superfine powder huoxiang zhengqi powder normal temperature preparation method; Efficiently solve that the energy consumption that exists in the present production is big, the medicine maximum particle diameter is difficult to accurate control, can't continuous production, difficult problems such as dust is many in the production process, make the finished medicines of preparation have rapid-action, good effect, bioavailability is high, the clinical application amount is few effect.
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 huoxiang zhengqi powder normal temperature preparation method.
Superfine powder huoxiang zhengqi powder normal temperature preparation method of the present invention comprises the steps:
The first step, choose crude drug Herba Pogostemonis, Folium Perillae, Poria, the Radix Angelicae Dahuricae, Pericarpium Arecae, Pericarpium Citri Reticulatae, Radix Platycodonis, the Rhizoma Atractylodis Macrocephalae (stir-fry), Cortex Magnoliae Officinalis, Rhizoma Pinelliae Preparatum, licorice piece respectively; Clean, dry or dry to moisture≤10%;
In second step, respectively that above-mentioned raw materials medicated powder is broken under 20 ℃～25 ℃ temperature, obtaining granularity is 60～120 purpose coarse powder;
The 3rd step, with the second step gained coarse powder in Herba Pogostemonis: the weight portion ratio mix homogeneously of Folium Perillae: Poria: the Radix Angelicae Dahuricae: Pericarpium Arecae: Pericarpium Citri Reticulatae: Radix Platycodonis: the Rhizoma Atractylodis Macrocephalae: Cortex Magnoliae Officinalis: Rhizoma Pinelliae Preparatum: Radix Glycyrrhizae=12:9:6:3:6:6:5:6:6:4:3;
The 4th step, with the 3rd step gained coarse powder place pulverize in the rod mill after; Be fed into special-purpose two-way airflow screening machine through wind and cross 500 mesh sieves, the air-flow that the powder that obtains particle diameter≤25 micron of sieving is produced by air-introduced machine is transported to collect in the tornado feeder set and promptly gets superfine powder huoxiang zhengqi powder finished product; The powder of not crossing 500 mesh sieves arrives circulation pulverizing once more in the said rod mill through the funnel collection and through line transportation.
