Description
Technical field
The present invention relates to food processing technology field, more particularly to a kind of big rice processing method for reducing content of cracking rice.
Background technology
At present, in the processing technology of rice, based on raw grain is received with machine substantially, agricultural production no longer carries out excessive removes to grain
Moisture removal is removed in miscellaneous, drying, causes raw grain easily to mix, cross pollution, impurity is more and more, and moisture is very high and uneven, to big
Meter Jia Gong brings very big difficulty.And after rice huller paddy, husk rice, the temperature of rice is higher, if being sent directly into polishing machine polishing,
Appearance sense organ is bad, and broken rice rate is high, and moisture content is higher, and the shelf-life is shorter.In addition constantly change with the consumption idea of people, it is right
The external sense organ of rice, mouthfeel also constantly propose new requirement, how to prepare a kind of in good taste, and water content is low, and broken rice rate is low
Rice processing technique, turn into the current technical issues that need to address.
The content of the invention
Based on technical problem existing for background technology, the present invention proposes a kind of rice processing side for reducing content of cracking rice
Method, step clear and rational, rice mouthfeel are fabulous, and do not damage rice structure, can omit follow-up removal of impurities process, ensure impurity
On the premise of content is extremely low, crack rice few.
A kind of big rice processing method for reducing content of cracking rice proposed by the present invention, comprises the following steps：
S1, by medical stone powder, hydrochloric acid stir, filter, washing, add absolute ethyl alcohol, ammoniacal liquor, water stirring, add metatitanic acid just
Butyl ester stirs, and filtering, vacuum calcining obtains prefabricated material；
S2, zeolite powder, carragheen, silane coupler are added into prefabricated material, and be sent into ball mill, add water, ground, mistake
Filter, wash, dry, add fresh paddy stirring, isolated pretreatment paddy；
S3, pretreatment paddy is sent into hulling machine removes rice hulls to obtain paddy rough；The rough grain separating machine of being sent into of paddy is carried out
The rough isolated brown rice of paddy；Brown rice is obtained by classification processor sieving and grading, multiple tracks husk rice, rice polishing, ventilation successively
Cool rice；Cool rice is passed through into pearling, polishing and selecting rice color successively, then finished, sterilization obtains rice.
Preferably, in S1, concentration of hydrochloric acid 1-1.4mol/L.
Preferably, in S1, medical stone powder, hydrochloric acid, absolute ethyl alcohol, ammoniacal liquor, water, the weight ratio of tetrabutyl titanate are 70-90：
180-220：160-180：4-8：50-70：8-16.
Preferably, it is that 1-1.4mol/L hydrochloric acid stirs by weight by 70-90 parts medical stone powder, 180-220 parts concentration in S1
8-12h is mixed, is filtered, washing, 160-180 parts absolute ethyl alcohol, 4-8 parts ammoniacal liquor, 50-70 parts water stirring 40-60min is added, adds
8-16 parts tetrabutyl titanate stirs 4-8h, and whipping temp is 65-75 DEG C, and filtering, vacuum calcining obtains prefabricated material.
Preferably, in S2, prefabricated material, zeolite powder, carragheen, silane coupler, the weight ratio of fresh paddy are 80-100：
20-40：3-6：1-2：300-500.
Preferably, in S2, added by weight into the prefabricated material of 80-100 parts 20-40 parts zeolite powders, 3-6 parts carragheen,
1-2 part silane couplers, and be sent into ball mill, it is 30-50wt% to add water to water content, grinds 10-18min, filtering, washes
Wash, dry, add the fresh paddy of 300-500 parts and stir 4-8h, mixing speed 10-20r/min, isolated pretreatment rice
Paddy.
For the present invention by medical stone powder after hydrochloric acid acidification, surface covering tetrabutyl titanate hydrolyzes the titanium dioxide of generation
Silicon, and loose micro-sphere structure is formed, not only excellent adsorption, and because inside is interlaced open structure and duct knot
Structure, specific surface area are very big；Carragheen, dialdehyde starch cooperation under, grind, not only disperse equal in ball mill with zeolite powder
Even, top layer is grafted to form network structure, not only extreme hardness, and top layer good water absorption after vacuum calcining, meets internal suction after water
Attached excellent performance, promotes moisture content internally to spread, and retentiveness is excellent, and the paddy for adding harvesting is stirred, not only can be to paddy
The debris on surface is scraped and removed, while the moisture on paddy top layer is adsorbed, and avoids the debris after scraping from adsorbing again
Paddy surface, then again successively by removing rice hulls, the rough separation of paddy, sieving and grading, husk rice, polishing, ventilation, pearling, polishing
And after selecting rice color, gained rice impurity content is extremely low.
Step clear and rational of the present invention, rice mouthfeel are fabulous, and do not damage rice structure, can omit follow-up removal of impurities process,
On the premise of ensureing that impurity content is extremely low, crack rice few.Rice water content of the present invention is 8-1wt%, and broken rice rate is extremely low, does not surpass
4% is crossed, meets national standard GB1354-2009 relevant regulations.
