Description

A kind of flour processing method

Technical field

The invention belongs to food processing technology fields, and in particular to a kind of flour processing method.

Background technique

Currently, flour industry development shows two main trend, on the one hand with the continuous improvement of people's living standards, opposite The precision of powder and Flour product, nutrition and the requirement of quality are higher and higher.But there is complex process for existing flour processing, if Standby, civil engineering etc. invests biggish defect.

Summary of the invention

The object of the present invention is to provide a kind of simple process, the flour that the flour accuracy of preparation is high, ash content is low, quality is good adds Work method.

The technical solution adopted by the present invention is that a kind of flour processing method, comprising the following steps: 1. stock up: by wheat into Row cleaning, removes impurity；2. dirty wheat matches: carrying out secondary screen to wheat, secondary to thresh wheat, secondary to remove stone, selection by winnowing, makes clear three times Wheat dust and weed-trifles impurity≤0.15% after reason, gravel content≤0.015% therein, different kind Cereals≤0.3%, by above-mentioned wheat It is uniformly mixed；3. net wheat proportion: 2. wheat that step is obtained carries out secondary screen, once threshes wheat, once removes stone, tertiary air Choosing, primary cleaning, air draught separation, wheat dust and weed-trifles impurity≤0.1% after making cleaning, gravel content≤0.01% therein, Different kind Cereals≤0.1%, above-mentioned wheat is uniformly mixed；4. wheat wetting: 3. wheat that step is obtained is placed in wheat wetting storehouse, right Wheat carries out spray infiltration, and dampening is that per kilogram wheat spills clear water 0.1-0.2kg, is stirred continuously while spraying, so that small Wheat homogeneous immersion, the wheat by infiltration are transferred in net wheat cabinet wheat wetting 21-24 hours；5. grinding: by wheat after step 4. wheat wetting It is ground using 17 grades, i.e. 8 reductions, 5 shellings, 2 sizing, 2 tail rolls, respectively 1M, 2M, 3M, 4M, 5M, 6M, 7M, CM, 1B, 2B, 3B, 4B, 5B, 1S, 2S, 1T, 2T carry out screen by bolting silk after grinding；6. clear powder: with wheat flour purifier by granule size phase Same material, i.e., pure endosperm particle, fine bran grain, even three kinds of different materials of quality of bran endosperm particle are separated；7. will The different grades of flour that screen comes out with what powder pipeline formed by 25 ~ 30 with powder system by being carried out with powder.Preferably, The step 7. in powder pipeline number be 28.The beneficial effect comprise that being matched by dirty wheat proportion and net wheat Than being applied in combination, by wheat dust and weed-trifles impurity, sandstone, different kind Cereals impurity content be reduced to very low level, thus It lays a good foundation to process the flour that precision is high, quality is good；Make the ash content in fine powder using flour processing method of the invention The content of ashes that content reduces in 0.03% ~ 0.04%, wheat-middlings reduces 0.2 ~ 0.3%.

Specific embodiment

The present invention is further explained in the light of specific embodiments, and but the scope of the present invention is not limited thereto.

Embodiment 1: a kind of flour processing method, comprising the following steps: 1. stock up: wheat is cleared up, remove impurity； 2. dirty wheat matches: carrying out secondary screen to wheat, secondary to thresh wheat, secondary to remove stone, selection by winnowing, the wheat dust and weed-trifles after making cleaning are miscellaneous three times Matter (mass content)≤0.15%, gravel content (mass content)≤0.015% therein, different kind Cereals (mass content)≤ 0.3%, above-mentioned wheat is uniformly mixed；3. net wheat proportion: 2. wheat that step is obtained carries out secondary screen, once threshes wheat, one It is secondary to remove stone, selection by winnowing three times, then primary cleaning (carrying out using Automatic-flow screen selected) is carried out, an air draught is carried out using air suction separator Separation, the wheat dust and weed-trifles impurity (mass content)≤0.1% after making cleaning, gravel content (mass content)≤0.01% therein, Different kind Cereals (mass content)≤0.1%, above-mentioned wheat is uniformly mixed；4. wheat wetting: 3. wheat that step is obtained is placed in profit In wheat bin, spray infiltration is carried out to wheat, dampening is that per kilogram wheat spills clear water 0.1-0.2kg, constantlys while spraying and stirs It mixes, so that uniform wheat infiltrates, the wheat by infiltration is transferred in net wheat cabinet wheat wetting 21-24 hours；5. grinding: 4. step is moistened Wheat is ground using 17 grades after wheat, i.e. 8 reductions, 5 shellings, 2 sizing, 2 tail rolls, respectively 1M, 2M, 3M, 4M, 5M, 6M, 7M, CM, 1B, 2B, 3B, 4B, 5B, 1S, 2S, 1T, 2T carry out screen by bolting silk after grinding；6. clear powder: will with wheat flour purifier The identical material of granule size, i.e., pure endosperm particle, fine bran grain, even the different material of three kinds of quality of bran endosperm particle carries out Separation；7. being carried out the different grades of flour that screen comes out by matching the powder system of matching that powder pipeline forms by 28 with powder.It is logical It crosses dirty wheat proportion and net wheat proportion is applied in combination, by the content reduction of dust and weed-trifles impurity, sandstone, different kind Cereals impurity in wheat To very low level, to lay a good foundation to process the flour that precision is high, quality is good；In conjunction with the grinding technics in bright, The content of ashes that the present invention reduces the content of ashes in fine powder in 0.04%, wheat-middlings reduces 0.3%.
