Abstract
The invention discloses a kind of processing technologys of rice, for traditional handicraft is once completed to shell completely, the mechanism that paddy is subject to weakens, and herein under weaker effect, still there is unhulled paddy, then the husk of this part paddy and rice adherency are close, so just it is difficult to decladding, therefore the joint operation for first soaking and drying afterwards is then employed, wetting expands husk, then it is dry that then there is contraction, such one one contracting, contribute to the adhesive attraction of reduction husk and rice, most afterwards through secondary husk rice, just the unhulled paddy of husk rice is thoroughly shelled easily.Technique is dried compared with tradition drying and direct disposable high temperature drying to paddy, and the effect for taking away paddy internal moisture mitigates, and is heated evenly；With reference to wetting and drying process, through secondary husk rice, compared with traditional handicraft, the drying steps after wetting and wetting are increased, greatly reduce broken rice rate, same a batch of paddy of the method for the present invention processing, broken rice rate has reached less than 8%.
Description
Technical field
The present invention relates to Rice producing fields.
Background technology
Rice is one of traditional staple food in China and the Main Foods of the south China people.Rice is the element that supplements the nutrients
Basal diet, can be human body also containing protein, fat, vitamin and 11 kinds of minerals other than being rich in carbohydrate
Comprehensive nutrition is provided.At present, the main problem that rice processing occurs is since paddy husk glues more firm, husk rice process
Cause to crack rice more, cause the loss of rice, also increase the workload that subsequent broken rice sieve goes out process, increase rice processing
Cost, meanwhile, the particle processed differs, and taste is bad, affects the processing quality of rice.
Invention content
The purpose of the present invention is to provide a kind of processing technologys of rice, and the rice produced is clean, finish is good, cracks rice
Rate is low.
To achieve the above object, the present invention adopts the following technical scheme that：
A kind of processing technology of rice, includes the following steps：
(1) it cleans：The paddy of harvesting is put into impurity removing machine and removes impurity, is then spread in drying shed；
(2) it is dry：It is repeatedly dried using hot wind to spreading the paddy in drying shed；The hot blast temperature is 35-
It 45 DEG C, often takes out and stirs, and be dried again after cooling down 10min after dry 50-60min, until Rice Kernel Moisture Content is 18-20%,
Finally paddy is cooled to room temperature；
(3) paddy decladding：Decladding processing carries out paddy after drying using rice huller bone machine, the gap of rice huller bone machine glue rod is no more than
2mm, husking yield ＞ 80%；
(4) husk rices：Brown rice and unhulled paddy are separated using grain separating machine, separation rate ＞ 99%, it will
Rough and pearling is carried out out in brown rice input rice mill, obtains semi-finished product；
(5) it soaks：Semi-finished product are atomized, surface of semi-finished is made to adhere to water mist；The semi-finished product for being atomized wetting are put into
It is taken out after heating 2-5s in 320 DEG C of steam；
(6) it is dry：The dry wind of -5-5 DEG C of the semi-finished product process of wetting is dried, it is 12- to make semi-finished product moisture content
14%；
(7) secondary husk rice：It is rolled again in dried semi-finished product input rice mill, the postcooling that makes to shell completely is to room
Temperature obtains rice just finished product；
(8) it polishes：Rice is polished using polishing machine, makes the Starch formation gelatinous layer of rice surface, makes rice brilliant
Jade-like stone is bright, extends the shelf life；
(9) color sorting：Heterochromatic grain is removed using color selector.
(10) it is classified：Perfect kernel is detached with imperfect grain using rice bolter.
Beneficial effects of the present invention：For traditional handicraft is once completed to shell completely, mechanism that paddy is subject to
Weaken, and herein under weaker effect, still there is unhulled paddy, then the husk of this part paddy and rice adherency are close, so
Decladding is just difficult to, therefore then employs the joint operation for first soaking and drying afterwards, wetting expands husk, and then drying then has
Contraction, such one one contracting help to reduce the adhesive attraction of husk and rice, most just easily will through secondary husk rice afterwards
One time the unhulled paddy of husk rice thoroughly shells.Dry technique and tradition drying and directly disposable high temperature drying phase to paddy
Than the effect for taking away paddy internal moisture mitigates, and is heated evenly；With reference to wetting and drying process, through secondary husk rice, with traditional work
Skill is compared, and increases the drying steps after wetting and wetting, greatly reduces broken rice rate, the same batch of the method for the present invention processing
Paddy, broken rice rate reached less than 8%.
