Description
The present invention relates to a kind of air flow-guiding method and a kind of corase grind material wheat flour purifier that is used to roughly grind the clear powder of material, wherein material carries out powder clearly through a plurality of sieve layers that supporting quiveringly, that constitute clear powder section, and separates by desired grade by the material discharger of tailing and a plurality of adjustable outlet connection below the sieve layer, that be used for minus mesh is transported to two or more feeders.
Except roller flour mill and plansifter, corase grind material wheat flour purifier can be used as main frame, and it has the common peculiar characteristic of the industry processing technology of milling, that is:
-technical process is opened wide and is carried out, and can see material in each treatment step;
-in critical process, can take a sample and carry out the sensing technology evaluation or carry out analytical review;
-grinder can be proofreaied and correct machine adjustment and material fluidity.
In corase grind material wheat flour purifier, follow the oscillating movement of sieve to combine principle and traditional screening of fluid bed.
Common screening process great majority are not have air to carry out under by the situation of sieve; In contrast, give birth to a fluid bed, make material present a kind of flow regime of approximate fluid by a powerful air miscarriage.In this fluid bed, relate to multiple complete special regularity, wherein separate just effect the most familiar by thickness.The main task of corase grind material wheat flour purifier is to draw meal and middle powder, different granularity, and wheat bran is gone out clearly, and the darker color that these wheat brans have is brown usually.In addition, can adopt corase grind material wheat flour purifier that the product of milling that has without quality characteristic is separated.
In Germany Patent documents in 1884 29181, a kind of corase grind material wheat flour purifier that has a kind of system of complete closed is disclosed.Air is extracted and the air guiding is returned along the material collection district out the downside of sieve with a duplex blower fan from the machine top with cloth bag filter.Relative with technology status recently, the possible means that the work of corase grind material wheat flour purifier is monitored have a lot of shortcomings, and are particularly no longer suitable in the clear powder section with a plurality of sieve layers.
Modern senior the milling of industry of milling has such characteristics, except will reaching predetermined granularity, is also noted that some main points, particularly relating to aspect the material of milling:
-shallow lake the composition granule that is identified for the corase grind material of living wheaten food processing industry does not allow to be subjected to mechanical damage, otherwise will reduce the quality of living wheaten food.
The glutelin of-the flour that is used to toast does not allow for example to sustain damage by local heat.
-outer wheat bran must maintain its large tracts of land body as far as possible and separate.
Opposite with the cube shape of corase grind material with previous flour, the large tracts of land characteristic of wheat bran will be utilized to separate in corase grind material wheat flour purifier.This separation relies in the exciting fluid bed and partly pushes, makes it to realize as the physical force that tailing is separated up in plane wheat bran.In corase grind material wheat flour purifier, have only flour partly and the corase grind material partly is sized and by size sorting.This process is analogous to the grading of being undertaken by the granularity spectrum of a regulation.
