Abstract
The invention discloses a method for preparing submicron powder for legehenne at normal temperature. The method comprises the following steps of: cleaning Chinese herbal medicinal decoction slices such as codonopsis pilosula, astragalus, tuckahoe, bighead atractylodes rhizome, malt, hawthorn, medicated leaven, south dodder seed, common cnidium fruit, and epimedium herb, and drying until the water content is less than and equal to 10 percent; crushing Chinese herbal medicines at room temperature to obtain coarse powder of which the granularity is 60 to 120 meshes; uniformly mixing the obtained coarse powder in a ratio; placing the obtained coarse powder in a rod mill and crushing, feeding into a two-way air flow screening machine special for the method by wind and screening to obtain powder of which the grain size is less than and equal to 25 microns, conveying the powder to a cyclone material collection device by air flow which is produced by a draught fan and collecting; and collecting powder which does not pass through a 500-mesh screen by using a funnel, conveying to the rod mill by a pipeline, and circulating and crushing again. The invention has the advantages that: the powder is prepared at normal temperature, the grain side of a finished medicine is less than and equal to 25 microns, the cell-wall breaking ratio and bioavailability are improved, and the used two-way air flow screening machine simplifies the method for preparing submicron powder for legehenne.
Description
Technical field
The present invention relates to the veterinary drug preparation field, especially relate to the precious normal temperature preparation method of superfine powder laying hen; The invention still further relates to the special-purpose two-way airflow screening machine that is used for this method.
Background technology
The laying hen treasured that is used to improve laying rate of laying hen at present is the powder of processing by after crude drug Radix Codonopsis, the Radix Astragali, Poria, the Rhizoma Atractylodis Macrocephalae, Fructus Hordei Germinatus, Fructus Crataegi, Massa Medicata Fermentata, Semen Cuscutae, Fructus Cnidii, the Herba Epimedii 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 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 laying hen precious 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 the precious normal temperature preparation method of superfine powder laying hen.
The precious normal temperature preparation method of superfine powder laying hen of the present invention comprises the steps:
