Abstract
The Chinese medicinal plant material pulverization includes the following steps: rough pulverizing material by using impact cutting pulverizing machine, then adopting high-frequency vibration impact grinding mode to make superfine pulverization of material. Its product fineness is high, and said invention adopts conventional equipment, and is favorable for next deep processing of plant material.
Description
The invention belongs to the processing technique field of plant medicine material, particularly the plant medicine material is carried out the method for fine pulverizing.
The plant medicine material is the comprehensive of all kinds of dry backs natural herbal, contains complicated ingredients such as fiber, lignin, starch and saccharide, if the inner withered cell wall of plant medicine can be pulverized, can improve its bioavailability greatly.In order effectively to utilize its medical value, need carry out superfine grinding earlier, compare with traditional treatment method some effective ingredient is kept to greatest extent, the preparation degree of Chinese medicine is improved.
The traditional handicraft that the plant medicine material is pulverized is an impact shearing method, will in the pulverizer of material input based on high speed strike and shear action material be pulverized.The defective of these methods is: one, product are too thick; Its two, the certain plants fibre length is longer, its product becomes floccule, is unfavorable for further disperseing and mixing.
The objective of the invention is to for overcoming the weak point of prior art, a kind of combination method for disintegrating micropowder composed of new plant medicine material is proposed, utilize impact shear formula crushing process that the selectivity of material cellulosic and other compositions is pulverized, the composition that makes easy pulverizing is in the refinement of coarse pulverization process, exposes to be difficult to comminuted fibres pledge material.Pulverize the further refinement of cellulosic material with the high-energy vibratory impulse again, fundamentally solve the problem of plant medicine material superfine grinding.
The present invention proposes a kind of combination method for disintegrating micropowder composed with the plant medicine material, it is characterized in that, may further comprise the steps:
1) earlier material is carried out coarse pulverization in impact grinder;
2) large granular materials that is difficult to pulverize is separated;
3) the ballistic mode of reuse dither is carried out fine pulverizing with fiberous material;
4) in centrifugal gas flow sizing machine, product is carried out staged care at last, obtain even-grained fine powder.
The impact velocity of said impact grinder can be in the scope of 20-60 meter per second; The impact acceleration of said dither impact grinding can be more than 4 times; The rotating speed of said centrifugal gas flow sizing machine can be selected between 500-3500 rev/min.
Basic feature of the present invention is:
At first adopt impact shear formula pulverizer that material is carried out coarse pulverization.The plant medicine material belongs to heterogeneous material, and bond strength is lower on the interface of fiber and skin and flesh.Tenacity of fibre is higher and be difficult for pulverizing in the low velocity impact crushing process, and refinement in advance in the dried skin and flesh class material fragility coarse pulverization process fortunately, and separates with fiberous material.The present invention can realize the coarse pulverization of most plant materials under the condition of the impact velocity of 20-60 meter per second, reach the purpose of tens of order fine powders.
Second step adopted the mode of dither impact grinding that the coarse powder product is carried out fine pulverizing.This high-octane impact acceleration forms very big local pressure at 4 times more than the acceleration of gravity on ballistic contact point, the fiber in the material is picked up broken cut-out or picked up withered plant cell broken.
The 3rd step adopted centrifugal gas flow sizing machine that the material that has carried out fine pulverizing is carried out staged care, and thick granule returns the dither impact grinder and pulverizes once more, and fine powder is collected at catcher as product.The desirable sorting rotating speed of centrifugal gas flow sizing machine can be selected between 500-3500 rev/min.
Plant medicine method for disintegrating micropowder composed of the present invention is compared with present ground method, mainly contains following characteristics:
The first, utilize the anisotropism and the more weak characteristics of interface bond strength of plant medicine material, at first realized coarse pulverization and fiber separation;
The second, the protruding end of dither impact grinding is effective;
The 3rd, the product fineness after centrifugal gas flow sizing machine is handled is even;
The 4th, technological process is simple, and equipment investment is few, to the adaptation face width of material.
