It vacuumizes and is filled with inert nitrogen gas, as long as product being made to store 12 months at normal temperatures, and quality remains to reach requirement.
Nitrogen is increasingly subject to favor in protection and fresh-keeping aspect.This method can make water fruits and vegetables, dish leaf etc. in high-nitrogen hypoxia
In environment, slow down metabolism, like hibernation-like state is entered, inhibits after-ripening, so as to long-period freshness preserving.According to experiment, nitrogen charging storage
Apple, still delicious and crisp is tasty and refreshing after 8 months, and the fresh-keeping of per kilogram apple is taken in 1 mao or so.Nitrogen charging storage can greatly reduce fruit
Busy season is lost, and can ensure that the supply in fruit dull season market, improves the quality of outlet fruit, increases income of earning foreign exchange.With
Science and technology progress and economic construction development, the application range of nitrogen is increasingly extensive, and be deep into many industrial departments and
Daily life field.
Corn because its yield is high, nutriment contained by adaptable, seed is abundant, have become in people's life can not or
One of scarce snack food.The nutritional ingredient of corn is more comprehensive, generally containing protein 8.5%, fat 4.3%, carbohydrate
73.2%, calcium 0.022%, phosphorus 21%, iron 0.0016%, also contain carrotene, vitamin B1, B2 and niacin and paddy is solid
Alcohol, lecithin, vitamin E, lysine etc., since its higher nutritive value and good taste are favored by people.Currently,
Occurs diversified instant corn on the market.But these instant corns are deposited still using vacuum packaging or frozen-pack
The problem of be：Vacuum niblet, after vacuumizing, niblet presses together, and shape has shriveled, and loses instant sweet tea
The crisp mouthfeel of sweet tea of niblet；And frozen-pack is easy that corn is made to occur to go bad, can not eat, and increases production cost.
Invention content
It is vacuum-packed with the instant corn of frozen-pack and under existing seed crimp, mouthfeel to solve existing use
Drop, the problem that quality reduces, production cost is high, the present invention provides a kind of processing technologys of nitrogen charging niblet, can not only protect
The full seed of niblet is held, the crisp mouthfeel of Endosperm of Sweet Corn is also improved, vacuum step is omitted, is improved with nitrogen charging discharge air
Efficiency 150%.
The present invention is that technical scheme applied to solve the technical problem is as follows：
The processing technology of the nitrogen charging sweet corn kernel of the present invention, includes the following steps：
Step 1: raw material harvests
Maize raw material is harvested in milking maturity latter stage, ensures that the breakage rate of corn kernel is minimum；
Step 2: transporting, entering factory
Maize raw material is processed by harvesting tandem, and different cultivars is stored classifiedly and processed, and is ensured within 12 hours
It machines；
Step 3: pol detects
The maize raw material of corn kernel pol >=10% is selected, ensures finished product seed pol 5% or more；
Step 4: peeling
By corn peeling, removal bract, filigree, insect and foreign matter ensure noresidue；
Step 5: transporting
Corn is transported at thresing machine using Turnround basket, the corn height that each Turnround basket is filled should be less than basket edge, prevent
Only corn extrusion；
Step 6: secondary select
With black grain, brown grain, foreign particle and will there are worm cave, breakage, rotten corncob to carry out cutting corruption；
Step 7: threshing
When threshing, pelletizing grain shape is uniform, and nothing is begun to crop up；
Step 8: cleaning
The niblet taken off is transferred in a cleaning machine, washes off useless grain and maize head；
Step 9: manually choosing grain
Choose the foreign matter remained in after cleaning in niblet, pest and disease damage grain, corn leaf, corncob, variegated grain, breakage
Grain；
Step 10: pack
The niblet selected is transported to the dress enterprising luggage grain of grain machine through conveyer belt, and dress grain machine is adjusted according to production requirement
