Abstract
The invention relates to a method for performing fine grinding on wheat. The method comprises the following steps of: (1) conveying cleaned wheat grains to a first-pass flour mill and crushing; and (2) screening the crushed grains, removing bran, performing subdivision processing on mixed powder of maximum grains and larger grains, and performing fine grinding on residual smaller grains. In the method, the powder obtained after crushing is divided into the grains with three particle sizes, and then the maximum grains and the larger grains are further screened; after the treatment, the part with lower nutrition content is ground into ordinary flour, and the part with higher nutrition content is ground into refined flour; the content of ash and wheat germs in the refined flour is lower, so that the content of nutrient components of the refined flour is higher and the refined flour has good mouthfeel; moreover, the higher whiteness degree can be achieved under the condition of not adding other ingredients.
Description
Technical field
The invention belongs to wheat abrasive dust technical field, especially the method for grow wheat correct grinding.
Background technology
Wheat is that a kind of it can make foods such as bread, steamed bun, biscuit after wearing into flour, also can make drinks such as beer through fermentation the extensive grass of plantation all over the world, and wheat is rich in nutritional labelings such as starch, protein, fat, mineral matter.
At present, the processing method of wheat is: at first wheat is carried out the foreign material cleaning, clear clean with sticking to the impurity on wheat surface such as dust, fine hair, microorganism etc. by wheat scourers, wheat washer etc., go out the impurity of larger particles through vibratory sieve, rotary flat sieve then, remove other impurity through miscellaneous equipment again, handle clean wheat grain and carry out the moisture adjusting, be delivered at last in the flour mill, obtain flour through break system, reduction system with after shining the reason system handles.
In the above-mentioned wheat abrasive dust process, wheat bran is eliminated out, can further process feed, and the nutrient content in the unit volume is low in the flour that rest parts grinds, this is because during the wheat abrasive dust, bigger endosperm particle, less endosperm particle and Mai Pi are mixed in together, and the mouthfeel of the flour after grinding and whiteness are all not good.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, provide wheat is screened the method that good, the nutritious grow wheat of flour mouthfeel after grinding and grinding is finish grinded.
The technical scheme that the present invention takes is:
The method of one grow wheat correct grinding is characterized in that: may further comprise the steps:
(1) wheat grain after the cleaning is delivered to the first road flour mill, carries out fragmentation;
(2) particle after the fragmentation screens, and removes wheat bran, and the mixed powder of the largest particles and larger particles is carried out the Subdividing Processing process, remainingly carries out the fine grinding process than the granule powder;
Described Subdividing Processing process is:
(1) the largest particles and larger particles mixed powder are delivered to wheat flour purifier and further remove wheat bran;
(2) mixed powder of further removing wheat bran is bulky grain, middle particle and granule through the wheat flour purifier screening, three kinds of particles grind through one second flour mill respectively, screen through screen cloth respectively then, the particle that does not meet size is sent to second flour mill again and grinds, wherein the flour that grinds of bulky grain is common flour, and the flour that middle particle and granule grind is refined powder;
Described fine grinding process is:
(1) is delivered to wheat flour purifier than the granule powder and further removes wheat bran;
(2) powder of further removing wheat bran grinds through the 3rd flour mill, and through the screen cloth screening, the particle that does not meet size is sent to the 3rd flour mill again and grinds then, and grinding the flour of finishing is common flour.
And the particle diameter of the mixed powder of described the largest particles and larger particles is 40～22 orders, is 40～55 orders than the particle diameter of granule powder.
And the bulky grain particle diameter in the described Subdividing Processing process is respectively 20～22 orders, and middle grain diameter is 25～32 orders, and the granule particle diameter is 32～34 orders.
Advantage of the present invention and good effect are:
Among the present invention, Powder screen after the fragmentation is told the particle of three kinds of particle size, then maximum and two kinds of bigger particles are further sieved, after handling like this, the part that nutrient content is lower grinds into common flour, and the part that nutrient content is higher grinds into refined powder, the content of ash content, wheat germ is lower in the refined powder, make the nutrient composition content of refined powder higher, mouthfeel is good, and need not add other composition and just can reach very high pale degree.
The specific embodiment
Below in conjunction with embodiment, the present invention is further described, and following embodiment is illustrative, is not determinate, can not limit protection scope of the present invention with following embodiment.
The method of one grow wheat correct grinding may further comprise the steps:
1. the wheat grain after the cleaning is delivered to the first road flour mill, carries out fragmentation;
2. the particle after the fragmentation screens, and removes wheat bran, and the mixed powder of the largest particles and larger particles is carried out the Subdividing Processing process, remainingly carries out the fine grinding process than the granule powder.
The particle diameter of the mixed powder of the largest particles and larger particles is 40～22 orders, is 40～55 orders than the particle diameter of granule powder.
The Subdividing Processing process is:
(1) the largest particles and larger particles mixed powder are delivered to wheat flour purifier and further remove wheat bran;
(2) mixed powder of further removing wheat bran is bulky grain, middle particle and granule through the wheat flour purifier screening, three kinds of particles grind through one second flour mill respectively, screen through screen cloth respectively then, the particle that does not meet size is sent to second flour mill again and grinds, wherein the flour that grinds of bulky grain is common flour, and the flour that middle particle and granule grind is refined powder.
Bulky grain particle diameter in the Subdividing Processing process is respectively 20～22 orders, and middle grain diameter is 25～32 orders, and the granule particle diameter is 32～34 orders.
The fine grinding process is:
(1) is delivered to wheat flour purifier than the granule powder and further removes wheat bran;
(2) powder of further removing wheat bran grinds through the 3rd flour mill, and through the screen cloth screening, the particle that does not meet size is sent to the 3rd flour mill again and grinds then, and grinding the flour of finishing is common flour.
Testing result through refined powder after grinding is as follows:
Among the present invention, Powder screen after the fragmentation is told the particle of three kinds of particle size, then maximum and two kinds of bigger particles are further sieved, after handling like this, the part that nutrient content is lower grinds into common flour, and the part that nutrient content is higher grinds into refined powder, the content of ash content, wheat germ is lower in the refined powder, make the nutrient composition content of refined powder higher, mouthfeel is good, and need not add other composition and just can reach very high pale degree.
