Production Information

Nitrogen controlled atmosphere storage is an technology which can slow down grain quality change by blow nitrogen to grain heap to chage the air components to protect grain from mold and kill insects.

Now, more and more attention has been aprid to food safety and enviromental protection in world wide. And the restrictions on chemical agents for the control of grain pests have become increasingly stringent. Developed countries have gradually reduced the use of chemicals in grain storage. The World Food and agriculture Organization requiers member states to gradually reduce on the use of chemicals in food storage process until ban in 21th century to meet the growing consumer demand for green food

Grain pest control
Compared with conventional grain storage, nitrogen gas ccan sffectively conctrol the stored grain pests, and solve the problem of single-dependency, pest resistance and the increase of dosage of th phosphating agent.

Grain microbial inhibition
The gas has significant effect on the metabolic activity of fungi.
Temperature control and nitrogen gas combine has good perfomance in keep grain quality, the rage of fatty acid rise faster than conventional storage, color,smell normal, detection in .

Summary
1.  Nitrogen controlled atomosphere storage’s effect of insects kill is closely related to sil’s air tightness, the higher nitrogen concentrition is, the better insect kill effect.
2.  Nitrogen controlled atomosphere storage can keep grain quality well, and won’t happen quality fast change after unseal.
3.  When concentration of nitrogen is higher than 98%, will have inhibitory effect to insects.
4. Though operation cost of Nitrogen controlled atomosphere storage is little higher than normal condition storage, but it achieves green storage, enviroment friendly.
