Description
Technical field
The present invention relates to rice processing technique field, more particularly to a kind of processing work of the low rice of the bright and clean broken rice rate of appearance
Skill.
Background technology
For the edible of rice, there is the history of more than one thousand years in China, particularly northern area resident is for rice
Like have been over other staple foods.At present in the processing technology of rice, based on raw grain is received with machine substantially, peasant household is no longer right
Grain carries out excessive removal of impurities, dries moisture removal, causes raw grain to mix, impurity is more and more, and moisture is high and uneven, to rice
Processing brings very big difficulty, and after attacking paddy, pearling, appearance sense organ is not clean, and rice finished product rate is relatively low.
The content of the invention
The present invention proposes a kind of processing technology of the low rice of the bright and clean broken rice rate of appearance, and present invention process is simple, cracks rice
Rate is extremely low, and appearance is bright and clean, and removal of impurities is thorough, and rice is in good taste.
The present invention proposes a kind of processing technology of the low rice of the bright and clean broken rice rate of appearance, comprises the following steps：
S1, iron chloride, Arabic gum, ethylene glycol ultrasonic disperse is uniform, reaction of the feeding with polytetrafluoroethyllining lining
Sealed in kettle, be subsequently placed in solvent thermal reaction in baking oven, Magneto separate, clean, spray drying, obtain magnetic absorption material, magnetropism
Dry paddy is added in absorption material to stir, and cooling stirring, obtains pre-processing paddy；
S2, paddy feeding hulling machine removal rice hulls will be pre-processed, the rough separation of grain separating machine paddy is re-fed into after Magneto separate
Obtain brown rice；
S3, brown rice is passed through to sieving and grading, rice polishing, pearling and selecting rice color successively, it is bright and clean broken that sterilization obtains appearance
The low rice of rice rate.
Preferably, in S1, iron chloride, the weight ratio of Arabic gum are 1-2：0.5-1.
Preferably, in S1, in solvent thermal reaction, oven temperature is 180-200 DEG C, reaction time 2-7h.
Preferably, in S1, paddy is dried, the weight ratio of iron chloride is 40-80：1-2.
Preferably, add dry paddy in S1, in magnetropism absorption material to stir, its whipping temp is 70-80 DEG C.
Preferably, in S1,5-10 DEG C is cooled to, mixing time 5-15min.
Preferably, the processing technology of the low rice of the bright and clean broken rice rate of described appearance, comprises the following steps：
S1,1.4-1.8 parts iron chloride, 0.6-0.8 parts Arabic gum, 100-110 parts ethylene glycol ultrasound are divided by weight
Dissipate uniformly, be sent into the reactor with polytetrafluoroethyllining lining and seal, it is anti-to be subsequently placed in solvent heat in 194-198 DEG C of baking oven
3-5h is answered, Magneto separate, is cleaned, spray drying obtains magnetic absorption material, and adding 70-78 parts in magnetropism absorption material dries paddy
Stir, whipping temp is 74-78 DEG C, is cooled to 6-8 DEG C and continues to stir 10-12min, obtains pre-processing paddy；
S2, paddy feeding hulling machine removal rice hulls will be pre-processed, the rough separation of grain separating machine paddy is re-fed into after Magneto separate
Obtain brown rice；
S3, brown rice is passed through to sieving and grading, rice polishing, pearling and selecting rice color successively, it is bright and clean broken that sterilization obtains appearance
The low rice of rice rate.
In the present invention, Arabic gum contains substantial amounts of amino and carboxyl, coordinates iron chloride to pass through solvent thermal reaction, Arabic
Gluing to be attached to the ferroso-ferric oxide surface to be formed, hardness is good, and dispersive property is good, and coordinates dry paddy to act on certain temperature
Lower and paddy suitably bonds, after low temperature stirring, paddy good dispersion, and adhesion, after being sent into hulling machine, due to paddy surface
Layer protective layer is coated, the structure of the survivable internal rice of mechanical dejacketing, broken rice rate is extremely low, in addition can be to rice top layer of shelling
Debris suitably scrape and remove, and avoid the debris after scraping from adsorbing again on rice top layer, in addition first by Magneto separate,
Not only impurity separation is easy and thorough, and can recycle again, and cost is extremely low, is divided further across grain separating machine
From product impurity content is further extremely low.The processing technology program of the present invention is relatively easy, can complete the finishing of rice, and
And rice milling yield is high, the rice produced is clean, finish is good, and rice mouthfeel is fabulous, and broken rice rate is extremely low, and no more than 3%, impurity contains
Measure extremely low, and water content is 4-8wt%, meets national standard GB1354-2009 relevant regulations.
