Abstract
The invention discloses a normal-temperature preparation method for ultrafine golden follower asthma-relieving powder. The method comprises the following steps of: selecting flos daturae, ephedra, semen bitter almond, gypsum and alum according to a certain proportion, smashing the bitter almond, extracting almond oil, and smashing together with other medicaments into coarse powder; putting the obtained coarse powder into a rod mill for smashing, conveying into the special bilateral airflow sieving machine through wind for sieving with a 500-mesh sieve, conveying the powder obtained by sievingto a cyclone aggregator through airflow generated by a draught fan for collecting to obtain ultrafine golden follower asthma-relieving powder; collecting powder which is not sieved with the 500-mesh sieve, and conveying to the rod mill through a pipeline for smashing circularly once again; and uniformly mixing the collected ultrafine golden follower asthma-relieving powder with the extracted almond oil to obtain finished ultrafine golden follower asthma-relieving powder. The method has the advantages that: the entire preparation process is performed at the normal temperature; 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 sieving machine, the preparation process of the ultrafine golden follower asthma-relieving powder is simplified.
Description
Technical field
The present invention relates to the veterinary drug preparation field, especially relate to superfine powder datura flower asthma relieving powder normal temperature preparation method; The invention still further relates to the special-purpose two-way airflow screening machine for this method.
Background technology
Being applied to the datura flower asthma relieving powder that domestic animal is relievingd asthma, cough-relieving is used at present is by the powder of making after crude drug Flos Daturae, Herba Ephedrae, Semen Armeniacae Amarum, Gypsum Fibrosum, the Alumen coarse pulverization, have that dosage is big, dosage form is thick, appearance poor, effective ingredient can not fully discharge, the low deficiency that waits of bioavailability 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 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 the popularization on veterinary clinic and use.
Summary of the invention
The object of the invention is to provide a kind of superfine powder datura flower asthma relieving 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 produce continuously, difficult problems such as dust is many in the production process, make the finished medicines of preparation have rapid-action, good effect, bioavailability height, effect 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 datura flower asthma relieving powder normal temperature preparation method.
Superfine powder datura flower asthma relieving powder normal temperature preparation method of the present invention comprises the steps:
The first step, according to Flos Daturae: the ratio of Herba Ephedrae: Semen Armeniacae Amarum: Gypsum Fibrosum: Alumen=4:2:3:8:3 is chosen crude drug, earlier Flos Daturae, Herba Ephedrae is dried naturally or dries to moisture≤10%;
In second step, Semen Armeniacae Amarum pulverizing back proposition almond oil is standby, being crushed to granularity behind the Semen Armeniacae Amarum slag after the lixiviate and Flos Daturae, Herba Ephedrae and Chinese medicine Alumen, the Gypsum Fibrosum mix homogeneously under 20 ℃～25 ℃ temperature is 60～120 purpose coarse powder;
The 3rd step, with the second step gained coarse powder place pulverize in the rod mill after, be fed into special-purpose two-way airflow screening machine by 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 namely gets the datura flower asthma relieving powder ultramicro powder; The powder of not crossing 500 mesh sieves arrives circulation pulverizing again in the described rod mill through the funnel collection and by line transportation;
Can obtain superfine powder datura flower asthma relieving powder finished product behind the almond oil mix homogeneously of the 4th step, datura flower asthma relieving powder ultramicro powder that the 3rd step was collected and the extraction of second step.
Special-purpose two-way airflow screening machine of the present invention comprises casing and the downward screen drum of chamber intermediate openings that sets within it, the order number of described screen drum 〉=500 orders; The nozzle of screen drum is connected mutually with the funnel upper shed that is arranged on the casing bottom; Chassis cavity is connected with air-introduced machine by the negative pressure chamber on top; Be provided with the door font rotary jet pipe that is constituted by transverse tube and standpipe in the zone between screen drum and casing, the puff prot of described door font rotary jet pipe is for axially being opened in groove on its tube wall along described transverse tube and standpipe respectively, described groove is offered towards the screen drum direction respectively, the groove width 0.5-2 millimeter of groove, the middle part of transverse tube and drive motors driving coupling; Be provided with blast pipe in the screen drum centre position, the air outlet of described blast pipe passes that screen drum is connected with the transverse tube middle part of door font rotary jet pipe and rolls by rolling bearing and is connected; The air inlet of blast pipe extends outside the described hopper side walls and is connected with the blast orifice of aerator; Be provided with feed pipe in screen drum, be provided with the buffering umbrella above the discharging opening of described feed pipe, the charging aperture of feed pipe extends outside the hopper side walls and is communicated with powder conveying fan air outlet through wind stopping device.
