Description

The plant breaker of extraction efficiency can be improved
Technical field
The present invention relates to a kind of breaker, and in particular to can improve the plant breaker of extraction efficiency.
Background technology
Plant extracts (Plant extracts) refers to using appropriate solvent or method, from plant (plant all or Certain part) it is the material that raw material is extracted or is process, available for pharmaceuticals industry, food service industry, healthy industry, beauty industry And other industries.Plant extracts is using plant as raw material, according to the needs of the purposes of the final products to extraction, by thing Physicochemical extracts separation process, and a certain kind or plurality of active ingredients in orientation acquisition and concentration plant are effective without changing its Constituent structure and the product formed.Composition according to extraction plant is different, forms glucoside, acid, polyphenol, polysaccharide, terpene, flavones, life Alkaloids etc.;It is different according to character, vegetable oil, medicinal extract, powder, crystalline lens etc. can be divided into.The above extract is for certain in medical science A little diseases have important therapeutic effect, under the influence of new medical model, possess the plant extract product of feature or activity Enjoy favor.At present, plant extracts industry development is more and more faster, more than drug market growth rate, turns into independent new Emerging industry.And during plant extract, the effect of extracting and efficiency of active component in order to better improve, generally all can first by After plant is shredded or crushed, then extracted, but the cutting used in existing process or breaker efficiency Lowly, effect is bad, it is impossible to realizes the high efficiency extraction of postorder active components of plants well.
The content of the invention
The technical problems to be solved by the invention are the extractions of active component in order to better improve during plant extract Effect and efficiency are taken, after generally all first plant being shredded or crushed, then is extracted, but adopted in existing process Cutting or breaker efficiency are low, and effect is bad, it is impossible to realize efficiently carrying for postorder active components of plants well Take, and it is an object of the present invention to provide the plant breaker of extraction efficiency can be improved, can not only by integrating cutting with crushing It is efficiently quickly broken to plant progress, meanwhile, crushed, can be ensured after crushing again after first being carried out uniformly cutting The uniformity, do not easily cause the uneven of plant fragment, be advantageous to the abundant extraction of consequent activities composition.
The present invention is achieved through the following technical solutions:
The plant breaker of extraction efficiency, including disintegrating machine body can be improved, the top of the disintegrating machine body is set There is material bin, deflector is provided with the material bin, multiple pod apertures are offered on deflector, the size of pod apertures is broken with needing Broken plant diameter is identical, and the lower section of deflector is provided with following current post, is evenly distributed with following current through hole on the following current post, following current is led to Hole and the position of pod apertures correspond, and are arranged alternately successively from top to bottom on the both sides inwall of disintegrating machine body below following current post There is horizontal cutting knife, cutting knife moves back and forth along horizontal direction;The lower section of cutting knife is provided with the broken platform in triangular pyramid, crushes the cone of platform Offer breaking tank on face successively from top to bottom, parallel broken roller group, the broken roller group are provided with above the conical surface of broken platform Moved along the direction of the conical surface of broken platform, the breaker roll in broken roller group is moved in breaking tank.
The breaker of the present invention, by integrating cutting with crushing, plant can not only be carried out efficiently quick It is broken, meanwhile, crushed again after first being carried out uniformly cutting, the uniformity after crushing can be ensured, do not easily cause plant Thing fragment it is uneven, be advantageous to the abundant extraction of consequent activities composition.To need broken plant material be put into In hopper, in the presence of the pod apertures on deflector, form drops into the following current through hole of following current post to raw material in a certain direction Central, then plant material keeps falling state in following current through hole, when its lower end drops out following current through hole, cutting below The part that knife-edge is dropped out is cut, and by multiple cutting knife cross-cuts, both can guarantee that the granular size of cutting, and had been carried simultaneously Uniformity after height cutting, and efficiency high, plant material fall automatically under self gravitation, apply without additional energy source dynamic Power;Particle after cutting uniformly is dropped among the broken groove of the broken platform in lower section, and it is in triangular pyramidal to crush platform, compared to planar table For greatly add the quantity of breaking tank in broken platform, the particulate material in groove of being formed a team by breaker roll break simultaneously It is broken, the quantity for the raw material that can disposably handle is improved, substantially increases production efficiency;By cutting and broken junction Reason, greatly improves broken effect, and the plant made is broken more thoroughly, improves the quality of production.
The lower section of broken platform, which is provided with, rolls platform, rolls platform surface and is provided with pinch roller, the bottom of breaking tank offers conveying Hole, the sprocket hole run through the bottom of broken platform, and the material after broken is dropped into by sprocket hole to roll on platform, through overvoltage Wheel is further to roll grinding, improves fragmentation quality.
The top of the material bin inner deflector is provided with horizontal positioned stirring bar, and multiple stirrings are vertically connected with stirring bar Plate, stirring bar can be rotated around own axes, and material can be stirred by material rotating plate, enable plant material suitable Profit is entered in pod apertures.
The platform that rolls is hollow-core construction, and the upper and lower surface for rolling platform is mesh structure, and the lower section for rolling platform is provided with collection Liquid bath, tissue fluid is all contained for plant, therefore be likely in shattering process is ground to cause tissue fluid to squeeze out, pass through collection The tissue fluid that liquid bath squeezes out these is collected in case the extraction of consequent activities composition, avoids wasting.
