Description
Technical field
The present invention relates to food processing field, and in particular to a kind of preparation method of wheaten starch.
Background technology
Wheaten starch is a kind of powdered substance of pure white light, and its transparency is higher, and viscosity is strong and stable, easy gel
Change, ability of anti-deformation is high.It has the special performance to be compared of other starch, is that the most popular basis of food circle is former
Material, is widely used in the industries such as food, papermaking, weaving, clothes, pharmacy, chemistry, in recent years, development and people with society
Growth in the living standard, the production of purified diet, instant food, health food and nutraceutical with millet flour as raw material is fast
Speed increases, and the range of application of small rice starch also constantly expands, and its consumption figure is also in ascendant trend year by year.Current China major part is small
The production technology of wheat starch is relatively backward, has that sanitary condition is poor, wastewater discharge is big, yield is low, a unstable product quality etc.
Shortcoming, therefore the exploitation of wheat starch production technique has considerable economic potential.Development is wanted in China's wheaten starch industry,
There is certain status in fierce market competition, technique and equipment must just be transformed.
The content of the invention
The quality of wheaten starch, yield height are closely bound up with production technology, the present invention to influence wheat starch quality and
The equipment of yield is updated, and updates raw material proportioning and production technology, finally investigated a kind of the new of wheaten starch
Production technology.
Realize the technical scheme is that：A kind of preparation method of wheaten starch, step is as follows：
1）And face：Raw flour is transported to flour feeding silo by suitably matching somebody with somebody powder ratio, flour from powder workshop processed powder cabin.Hello
It is furnished with vibration discharger and quantitative auger in barrel storehouse.By frequency converter and control system, adjustment conveying auger rotating speed about 10-
Flour amount 6-10t/h is thrown in 20Hz, control；First intake and enter face again, to ensure to be well mixed.After flour enters continuous dough mixing machine, directly
Tap into row and be mixed to form starch adhesive, dough mixing machine electric current 35-50A is controlled by amount of water, flour is added to the water well mixed, flour
It is 1.1 with the mass ratio of water:0.9-1, it is 42%-60% that water content is starched behind mixing；
2）Homogeneous：Need to add a part of process water before homogeneous to dilute starch adhesive, homogenizer current control in 45-60A, to step 1）
Add water homogeneous in middle starch adhesive, and the starch adhesive moisture content after homogeneous is 65%-75%；
3）Three phase separation：By step 2）Starch adhesive after homogeneous is added to the separation of three phase separation centrifuge, obtains A starch/fiber；
4）Fiber wash：To step 3）In be diluted with water to 10-15 B é in A starch/fiber for obtaining, pump is to tapered fiber afterwards
Dimension sieve, using 9-11m3/h, pressure for the flushing water of 0.08-0.15mpa is rinsed, obtains not fibrous A- starch milks；
5）The sleeping spiral shell concentration of two-phase：By step 4）The A- starch milks for obtaining are added to the sleeping spiral shell concentration centrifuge of two-phase and are concentrated, dense
A- starch concentrations are 20-25 B é after contracting；
6）Smart A starch milks tank：By step 5）A- starch milks after concentration discharge into smart A starch milks tank, and discharging protein content≤
0.6%；The sleeping separated factor of spiral shell of two-phase is used for and face workshop section after reaching the bipyramid centrifuge clarification of 5000g as process water；
7）Dehydration：Step 6）The starch milk of middle smart A starch milks tank is dehydrated through flat lower unloader knife, moisture content after starch milk dehydration
It is 42-45%；Filtrate after dehydration returns to separation circuit and uses；
8）Drying：Step 7）Starch milk after dehydration is dried into Starch Drying System, drying EAT 100-
160 DEG C, 40-70 DEG C of a tail wind temperature, the starch milk moisture content after drying is 9%-14%；Steam pressure must if the scope less than 0.4
Must prepare to shut down, operation of being driven again after steam is normal.
The step 1）The temperature of reclaimed water is 28-32 DEG C.
The step 3）The variable vane wheel scale of middle three phase separation centrifuge is 405-415.
The step 4）The input concentration of tapered fibre sieve is 15-25m3/h, and excessive amount may then cause to run powder.
The beneficial effects of the invention are as follows：1）By the renewal with powder ratio and equipment to raw flour, production technology
Adjustment, improves product yield, reduces energy consumption, has saved production cost；2）The whiteness of wheaten starch is improve, egg is reduced
Bai Hanliang, improves product interior quality, improves the using effect of downstream client, is that company creates good economic effect
Benefit；3）The technique productions constant time range, small labour intensity, clean hygiene and wastewater discharge is small, energy saving technology environmental protection.The present invention increases
Plus conical screen further separates wheat bran, the whiteness of starch is heightened, reduced ash content；Separated with two sleeping spiral shells and instead of eddy flow
Device, improves the separating effect of starch and wheat gluten, reduces the protein content of wheaten starch, reduces water consume and improves
Yield, the temperature that the spiral shell that crouches is separate is lower than the temperature that cyclone is separate, close to the temperature of material, it is to avoid wheat shallow lake in production process
The gelatinization factor of powder, improves the interior quality and client's using effect of product,；Vacuum drum instead of using scraper, stabilization
Product moisture, saves steam, further increases the whiteness of wheaten starch.
