Abstract
The present invention belongs to the technical field of processing plant material. It is characterized by that firstly, it uses impact-shear pulverizer to make rough pulverization of plant material, and then uses high-frequency vibration and impact grinding mode to make superfine pulverization of the above-mentioned material. Said invention adopts the conventional equipment, and the product obtained by said invented method is high in fineness, has no agglomeration phenomenon for fibre material, and is favourable for deep-processing of the follow-up plant material products.
Description
The invention belongs to the processing technique field of plant material, particularly plant material is carried out the method for fine pulverizing.
Plant material is the comprehensive of all kinds of dry back crops and natural herbal, contains complicated ingredients such as fiber, lignin, starch and carbohydrate, if cell membrane that can inside plants is withered is pulverized, can improve its bioavilability greatly.In order effectively to utilize its economic worth, usually need to carry out earlier ultra-fine grinding, can make some nutritious composition but non-digestible material becomes functional food, the preparation degree of Chinese medicine is improved.
The traditional handicraft that plant 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 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 crushing 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 material ultra-fine grinding.
The present invention proposes a kind of combination method for disintegrating micropowder composed with plant material, it is characterized in that, may further comprise the steps: 1) earlier material is carried out coarse crushing in impact grinder; 2) large granular materials that is difficult to pulverize is separated; 3) mode of impacting with dither is again carried out fine pulverizing with fiberous material; 4) in centrifugal gas flow sizing machine, product is carried out classification at last and handle, obtain even-grained fine powder
Body.
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.
Essential characteristic of the present invention is:
At first adopt impact shear formula pulverizer that material is carried out coarse crushing.Plant 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 crushing process fortunately, and separates with fiberous material.The present invention can realize the coarse crushing 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 meal 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 the contact point that impacts, 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 classification and handles, and thick particle returns the dither impact grinder and pulverizes once more, and fine powder is collected at gatherer as product.The desirable sorting rotating speed of centrifugal gas flow sizing machine can be selected between 500-3500 rev/min.
Plant method for disintegrating micropowder composed of the present invention is compared with the method that grinds now, mainly contains following characteristics:
The first, utilize the anisotropism and the more weak characteristics of interface bond strength of plant material, at first realize
Coarse crushing 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.
Embodiment one:
Adopt impact grinder under the impact velocity of 40 meter per seconds Gynostemma pentaphylla to be pulverized, fibre length is in 1 millimeter, and big particle returns impact grinder and pulverizes once more after 30 mesh sieve divisional processing; To impact 20 minutes under the high-energy vibratory impulse effect of 6 times of acceleration of gravity, average length can reach 15 microns to screenings in high-frequency vibration grinder.After the sorting process through 1500 rev/mins centrifugal gas flow sizing machine, can obtain the above Gynostemma pentaphylla superfine powder of average fineness 800 orders again.
Embodiment two
Adopt impact grinder under the impact velocity of 60 meter per seconds the glossy ganoderma piece to be pulverized, fibre length is in 2 millimeter, and big particle returns impact grinder and pulverizes once more after 20 mesh sieve divisional processing; Screenings was with the high-energy vibratory impulse of 4 times of acceleration of gravity 30 minutes, and average length can reach 25 microns.After the sorting process through 800 rev/mins centrifugal gas flow sizing machine, can obtain the above glossy ganoderma ultra-fine powder body of average fineness 600 orders again.
