Description
Technical field
The present invention relates to flour processings, and in particular to a kind of flour low temperature low speed low pressure processing technology.
Background technique
The process of wheat flour milling powder is mainly exactly the process of separation wheat endosperm and wheat bran, plumule.Under ideal conditions, grind
Mill should separate as much as possible embryo in the case where not destroying starch granules integrity degree, reducing nutrient loss contained by wheat
Cream, but be difficult to.In fact endosperm (flour) content is up to 85% in every 100 grams of wheats, but is commercialized milled processed
Every 100 grams of wheats can only extract 70 grams or so flour, and extraction is less than 70%.Existing flour grinding technique is in order to improve wheat
Flour extraction needs the wheat bran to wheat and aging to be heated to soften plumule, is easier in this way by endosperm from wheat bran and plumule
In separate.The working environment of high temperature brings the high working strength of high pressure and flour mill, so that flour mill process of lapping mistake
In strong, the nutriments such as the protein in wheat endosperm (flour) is caused to be largely lost, the natural fragrance in wheat germ lose compared with
More, the starch chain molecular structure of flour is destroyed, and the stabilization time of dough is short, muscle degree is low, it is necessary to stabilizer, gluten-strengthening agent be added
The additives such as (benzoyl peroxide and potassium bromate industrial chemicals) oxidant enhance the stability, mouthfeel and muscle degree of flour,
Cause in flour carrotene etc. to be destroyed and drinking water be few when face and good face is difficult to roll out, looked at after face is cooked it is good-looking,
It tastes also chewiness, but there is no wheat fragrance.The edible flour containing additive in short term can make one to generate nausea, dizzy, nerve
Weak equal intoxicating phenomenons.Long-term consumption can cause serious damage, easily exacerbation burden of liver to liver, cause a variety of diseases,
In addition, containing micro amount of arsenic and lead in benzoyl peroxide, also there is certain toxic side effect to human body.In addition to this, it produces in this way
The usually inclined yellow of flour out, businessman add to make Flour colour bleach into brightening agent to sell, and brightening agent equally can be to edible
The body of person causes centainly to damage, and is not conducive to good health.
Summary of the invention
In order to solve the above-mentioned technical problem the present invention provides a kind of flour low temperature low speed low pressure processing technology, the face produced
Powder nutrition content is high, without adding additive it is ensured that Flour colour mouthfeel is all good.
The technical scheme to solve the above technical problems is that
A kind of flour low temperature low speed low pressure processing technology, includes the following steps；
S1, good quality wheat, the impurity being mingled in screening cleaning wheat are chosen；
Wheat after S2, screening is sent into rotatable silo, and pressure is sprayed into silo by cleaning device
The water that range is 2.5Mpa~3.5Mpa, temperature range is 65 DEG C~75 DEG C washes away animal waste, the ash of the attachment of wheat surface
Dirt, and preliminary softening is carried out to wheat and is moistened；
S3, wheat is placed in wheat wetting storehouse, wheat wetting is carried out to wheat, tempering time range is 15~16 hours, so that wheat
Endosperm is loose to be easy to crush, while wheat skin absorbs moisture and increases toughness；Wheat is carried out simply by blower while wheat wetting
It drains, prevents excess moisture, while achieving the effect that cooling；
S4, the wheat after wheat wetting is ground, wherein the range of speeds of flour mill is 450~550 revs/min,
The temperature range for keeping work is 35 DEG C hereinafter, the range for keeping operating pressure is 0.35Mpa~0.40Mpa；
S5, the net endosperm to generating after wheat flour milling, fine bran and company's three kinds of different materials of bran endosperm sieve；
S6, postsearch screening classification is carried out according to granule size to every kind of material after being sieving through；
S7, the material after classification is carried out respectively with powder and packs packing.
The beneficial effects of the present invention are: guaranteeing that the wheat materials for entering milling are cleaner, that is, guarantee the cleaning for grinding flour,
Wheat grain is ground using low temperature, low pressure, low speed simultaneously, farthest remains protein, the gluten in wheat
The various nutriments such as matter, carrotene, carbohydrate, calcium, phosphorus, iron, vitamin B1, B2, the especially Hu Luo in flour
Bu Su and vitamin E are 18 times of other flour.Its low speed, low pressure grinding feature maintain the complete of starch chain molecular structure again
The muscle degree of whole property, flour is guaranteed, while the loss of wheat wheat germ is smaller, and flour remains the genuineness of wheat, production
Various wheaten food mouthfeels are flexible, wheat it is aromatic it is strongly fragrant, nutritive value is higher, be the health-nutrition flour of real natural green.Third is that adopting
The flour produced with low temperature low speed low-voltage technology, does not need to add any chemical addition agent such as brightening agent, essence-replenishing preparation etc., ensure that
Flour accuracy, and its shelf-life was up to 12 months.
Based on the above technical solution, the present invention can also be improved as follows.
Including six shellings, 10 one of reductions, one of sizing tail rolls with together with further, in step s 4,.
Beneficial effect using above-mentioned further scheme is multistage grinding, guarantees that grinding quality is more preferable, flour extraction is higher.
Further, in step s 2, the cleaning device first into silo injection containing detergent 0.1%~
0.2% water, while silo being kept to rotate, guarantee that whole wheats in silo are all cleaned completely；Again to silo
Middle injection clear water, while silo being kept to rotate, guarantee to clean in the detergent adhered on wheat in silo and silo dry
Only.
Beneficial effect using above-mentioned further scheme is that the cleaning to wheat materials is cleaner, and wherein detergent can be used
Dish washing liquid removes pesticide residue, dust and the bacterium etc. adhered on wheat.
Further preferred, the silo is disc, and the bottom of the silo offers multiple leakage holes, institute
The center for stating silo bottom is equipped with rotating electric machine, and the rotating electric machine driving silo is rotated around the central axis of silo.
Beneficial effect using above-mentioned further scheme is the rotation by silo, drives wheat that can receive completely clearly
The water that cleaning device sprays reaches complete clean effect.
