Description
Technical field
The present invention relates to the production technology of hominy grits, the production technology of specifically a kind of purification hominy grits.
Background technique
Hominy grits is a kind of high-nutrition food produced by corn, pale yellow, and good water absorption is full of nutrition.With jade
The congee that rice crushed grain is made into, in good taste, absorption easy to digest, and it is cholesterol-free, it is favored by people, is diabetes and Changes of Patients With Cerebrovascular Diseases
Ideal food；It is made into infant's snack food with it, keeps the canteen nutrition of child richer.Traditional hominy grits processing technology
It is coarse, by simply clearing up, it is crushed peeling, isolated hominy grits, whole process cannot be guaranteed the quality of hominy grits, contain
Stone, metal impurities.CN201510483203 discloses a kind of production technology of hominy grits, and CN201610322950 is disclosed
A kind of hominy grits preparation method, although two kinds of technical solutions both increase the magnetic separation process of removal magnetic metal object, magnetic material
The removal of matter, which is thrown away, to be not thorough, there are no the removing step of nonmagnetic metal object, early period raw material pretreatment process cannot guarantee that it is mould
Become the removal of the impurity such as grain, heterochromatic corn, cinder, brick and glass.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of production technology for refining hominy grits, it can guarantee that hominy grits is pacified
Completely without miscellaneous, particle is uniform, infant food can be directly used for.
The technical solution used to solve the technical problems of the present invention is that:
A kind of production technology refining hominy grits, which is characterized in that carry out in the steps below:
(1) primary cleaning: high-grade maize raw material is chosen, is cleaned through rotary screen screen；
(2) it dries: being lower than 80 DEG C of low temperature dryings, make corn moisture content≤14%；
(3) secondary cleaning: sieve is combined in the cleaning through hole diameter of sieve (perforated) plate 4cm, goes removing light impurities, big miscellaneous and broken corn；
(4) magnetic separation: magnetic metal is removed through board-like magnetic separator；
(5) it clears up three times: first removing impurity through vibrating screen, then remove stone impurity through stone remover；
(6) moldy kernel, heterochromatic corn, cinder, brick and glass impurities color sorting: are removed through color selector；
(7) secondary magnetic separation: magnetic metal is further removed through board-like magnetic separator；
(8) be crushed, screen and mention embryo: Jing Sandao abrasive type rice whitening machine iron roll rice polisher with together with is crushed, then through vibrating screen screen, most
Embryo is mentioned by embryo machine is mentioned, obtains big grain hominy grits and corn bran and plumule；
(9) hominy grits that step (8) obtains magnetic separation three times: is removed into magnetic metal by board-like magnetic separator again；
(10) metal detections: the hominy grits that step (9) is obtained is removed non-magnetic in hominy grits by time formula metal detector
Property metal, including stainless steel, copper, aluminium；
(11) milling and screen: the big grain hominy grits that step (10) is obtained further is crushed by flour mill, obtains middle granule
Hominy grits and corn flour；Big grain hominy grits returns to flour mill and is crushed again；
(12) clear powder: the hominy grits that step (11) is obtained removes residual corn skin through wheat flour purifier；
(13) secondary metals detect: the hominy grits that step (12) obtains being waited formula metal detector by high-precision and is further removed
Nonmagnetic metal in hominy grits finally obtains purification hominy grits.
The present invention by adopting the above technical scheme, compared with prior art, beneficial effect is:
Increase color sorting, metal detection device, by color selector adjust background board effectively removes moldy kernel in corn, (it is white,
It is red) heterochromatic grain, corncob, cinder, brick, the impurity such as stone, especially glass, guarantee corn safety without miscellaneous；Metal detection
Instrument can effectively reject magnetism and nonmagnetic metal in hominy grits, and minimum rejects metal: the magnetic metal of 1.2mm, 1.5mm
The nonmagnetic metal of stainless steel, 2.0mm.By technical solution of the present invention, safety can be produced without miscellaneous, evengranular purification corn
Crushed grain can be directly used for infant food.
Detailed description of the invention
Fig. 1 is the process flow chart of the embodiment of the present invention.
Specific embodiment
The present invention is described in detail with reference to the accompanying drawings and embodiments.
Referring to Fig. 1, a kind of production technology refining hominy grits carries out in the steps below:
Step 1, the purchasing of raw materials, drying: by GB1353-2009 national standard it is second-class more than, purchase high-grade maize；Pre-cleaning: corn is former
Material passes through rotary screen, screen removal of impurities；Drying: using 80 DEG C of low temperature dryings are lower than, make corn moisture content≤14%.
Step 2, it puts in storage storage: the corn of step 1 is put into the good warehouse storage of ventilation equipment.
Step 3, primary cleaning: taking corn in storehouse to be put into the cleaning combination sieve of hole diameter of sieve (perforated) plate 4cm, go out it is light it is miscellaneous, it is big miscellaneous and
Broken corn.
Step 4, the corn of step 3 magnetic separation: is removed into magnetic metal by board-like magnetic separator.
Step 5, secondary to clear up and remove stone: the corn of step 4 being removed into impurity by vibrating screen, removes stone by stone remover
Head impurity.
Step 6, the corn of step 5 color sorting: is removed into moldy kernel, heterochromatic corn, cinder, brick and glass by color selector
Equal impurity.
Step 7, the corn of step 6 secondary magnetic separation: is removed into magnetic metal by board-like magnetic separator.
Step 8, it is crushed, screen and mentions embryo: the corn of step 7 is passed through into three abrasive type rice whitening machines iron roll rice polisher with together with
It is broken, then through vibrating screen screen, most mentioned embryo machine afterwards and mention embryo, obtain big grain hominy grits and corn bran and plumule.
Step 9, the hominy grits of step 8 magnetic separation three times: is removed into magnetic metal by board-like magnetic separator.
Step 10, a metal detection: the hominy grits of step 9 is passed through non-magnetic in time formula metal detector removing hominy grits
Property metal (stainless steel, copper, aluminium etc.).
Step 11, milling and screen: the big grain hominy grits of step 10 is further crushed by flour mill, obtains middle granule
Hominy grits and corn flour；Big grain hominy grits returns to flour mill and is crushed again.
Step 12, the hominy grits of step 11 clear powder: is removed into residual corn skin by wheat flour purifier.
Step 13, secondary metals detect: the hominy grits of step 12 being waited formula metal detector by high-precision and removes corn
Nonmagnetic metal in crushed grain.
Step 14, the product of step 13 metering packing: is subjected to metering packing；Wherein, byproduct corn bran, maize germ
Metering packing respectively；Hominy grits 20-50 mesh, the metering packing now of corn flour 60.
Technique described in the present embodiment, design are simplified, and color sorting function effectively removes moldy kernel, impurity and glass in corn
Glass, metal detector can reject nonmagnetic metal in hominy grits, guarantee hominy grits purification safety, without any impurity, can directly use
In infant food.
The foregoing is merely preferably feasible embodiment of the invention, not thereby limiting the scope of the invention,
It is all to change with equivalent structure made by description of the invention and accompanying drawing content, it is intended to be included within the scope of the present invention.
