Abstract
The invention discloses a processing technique for corn kernels and belongs to the technical field of grain and food processing. The processing technique for corn kernels comprises the following steps of: taking the corns with percentage of vitreous kernel being above 90%; processing the corns into 24-mesh corn grits; crushing the 24-mesh corn grits into 120-mesh corn powder; processing the corn powder by using an extrusion production line; realizing conveying, mixing, shearing, steaming and shaping in an extruder; and after performing first fluidized bed cooling, microwave drying and sterilizing, and secondary fluidized bed cooling on the shaped corn kernels, screening by using a vibration screen, thereby obtaining the corn kernels. According to the processing technique provided by the invention, the corn kernels with balanced indexes of protein, fiber, fat, and the like, good taste, yellow color, smooth appearance, full and nutritional ingredients can be produced.
Description
Technical field
The present invention relates to a kind of processing technology of beautiful benevolence rice, belong to grain, food processing technology field.
Background technology
The rice that present people eat roughly has two kinds, and a kind of is self-sow; Another kind is artificial.As the main body rice of people's diet, existing two kinds, a kind of is nature, and another kind is artificial rice.Rice is to be processed by paddy rice, and it is long-term edible as people's diet main body, can cause nutrition unbalanced, like albumen, fiber, fat etc.Therefore the synthetic rice who develops alternative nature rice balanced in nutrition, that mouthfeel is good has become the technical problem that those skilled in the art are badly in need of solving.
Summary of the invention
The processing technology that the purpose of this invention is to provide a kind of beautiful benevolence rice utilizes that this technology can produce that index balances such as albumen, fiber, fat, mouthfeel are good, the beautiful benevolence rice of golden yellow color, smooth in appearance, full, abundant nutrients.
The objective of the invention is to realize through following technical scheme:
The processing technology of beautiful benevolence rice adopts vitreousness to reach the corn more than 90%, and corn is processed into 24 order hominy grits; And then be ground into 120 purpose corn flour with 24 order hominy grits; Using extrusion line to process corn flour, specifically is that the dog-house of corn flour through oscillating feeder fed intake, after the use mixer fully stirs; Through feeding screw material is transported in the quality-adjusting device; Modified in quality-adjusting device, through the solid feeder raw material is fed in the extruder again, the liquid feeder begins in extruder, to add water simultaneously; In extruder, realize conveying, mixing, shearing, boiling moulding; Moulding jade benevolence rice realizes that through vibratory sieve screening both gets after cooling off through a fluid bed cooling, microwave drying sterilization, secondary fluid bed again, and the addition of water remains on 19-21% for making beautiful benevolence rice go out extruder moisture in the said liquid feeder.
The moisture of described corn flour is 12.5-14%, fat content≤1, fiber content≤0.8, protein content are 9-10.
Described extruder is 72 type twin (double) screw extruders.
The ability to work of described solid feeder is that 320 kilograms/hour, revolution are that 300rpm, cutting revolution are 1400rpm; The feeding capacity of liquid feeder is that per 100 kilograms solid material needs 22 kilograms drinking water; The cavity district temperature value of extruder is 2 90 ℃ of warm areas, 3 120 ℃ of warm areas, 4 125 ℃ of warm areas, 5 40 ℃ of warm areas, 6 30 ℃ of warm areas, 87 ℃ of die head temperatures, die pressure 5.9Mpa.
The addition of water remains on 20% for making beautiful benevolence rice go out extruder moisture in the described liquid feeder.
Owing to adopt technique scheme, make the present invention have following advantage and effect:
Adopt that processing technology of the present invention can produce that the mouthfeel of index balances such as albumen, fiber, fat is good, the beautiful benevolence rice of golden yellow color, smooth in appearance, full, abundant nutrients, thereby realize the large-scale industrial production of beautiful benevolence rice.The present invention adopts vitreousness to reach corn flour that the corn more than 90% is processed into as raw material, and deep processing becomes artificial beautiful benevolence rice, and its nutritional labeling is relatively more balanced.Moreover, also more natural rice is good on mouthfeel, the color and luster.Use extrusion process with the cutin corn flour as raw material; The beautiful benevolence rice that processes with extrusion line; Through series of process such as conveying, mixing, shearing, boiling, drying and moulding; Have the advantages that the processed and applied scope is wide, production efficiency is high, the goods nutritive loss is few, helps digesting and assimilating.
The specific embodiment
Below in conjunction with embodiment and test data the present invention is explained in further detail.Following examples are merely specific embodiment of the present invention, but design concept of the present invention is not limited thereto, and allly utilize this design that the present invention is carried out the change of unsubstantiality, all should belong to the behavior of invading protection domain of the present invention.
Method among the following embodiment if no special instructions, is conventional method.
Percentage composition among the following embodiment is the quality percentage composition if no special instructions.
Embodiment 1:
The processing technology of beautiful benevolence rice adopts vitreousness to reach the corn more than 90%, and corn is processed into 24 order hominy grits; And then be ground into 120 purpose corn flour with 24 order hominy grits, and use extrusion line to process corn flour, specifically be that the dog-house of corn flour through oscillating feeder fed intake; After using mixer fully to stir; Through feeding screw material is transported in the quality-adjusting device, modified in quality-adjusting device, through the solid feeder raw material is fed in the extruder again; The liquid feeder begins in extruder, to add water simultaneously; In extruder, realize conveying, mixing, shearing, boiling moulding, moulding jade benevolence rice realizes that through vibratory sieve screening both gets after cooling off through a fluid bed cooling, microwave drying sterilization, secondary fluid bed again; The addition of water remains on 19-21% for making beautiful benevolence rice go out extruder moisture in the said liquid feeder, and the addition of water is best to remain on 20% for making beautiful benevolence rice go out extruder moisture
