Beginning of the 21st century, UN Food and Agriculture Organization of the process of grain and oil storage fumigant use will be further restricted and prohibited, and actively advocate in order to regulate the grain stack gas composition (controlled atmosphere storage) to change the pests, mold of the living environment, reduce food their aerobic respiration, to stored grain security, the purpose of delaying aging, green grain storage implementation.
With the people's living standards improve, the target of food is also more and more attention to hygiene. Nitrogen application equipment, grain storage has been fully able to meet the pursuit of green food and green grain storage is the formation of our country of choice for new technologies.
Victoria Green Group introduced nitrogen stored grain products, effective implementation of the green grain storage purposes. Manufactured to a certain degree of purity nitrogen, pressure, temperature and flow within the conveyor to the warehouse, through the warehouse atmosphere of nitrogen in the food pipeline will be evenly spread of sand, when the concentration increased gradually and after a certain period of time to maintain the pest damage and living environment for mold, causing suffocation and death pests, suppression of food physiological breathing, slow down aging food, and ensure the quality of stored grain.

1. Will be hot and cold start, boot to target a few minutes;
2. New energy-saving technology to make energy consumption of only 75% of products;
3. Absorption tower enhance the flow distributor to maximize the utilization of molecular sieve to reduce the impact of molecular sieve bed, improve the long-term use of molecular sieve;
4. Composite filled with molecular sieve to ensure that the most effective loading effects;
5. Cylinder pressed to achieve the volume of solid material to sink "visualization", a compact molecular sieve bed alarm, the second self-locking pressed to avoid the loss of the zeolite powder to make the system more secure and reliable;
6. Purity nitrogen gas line detection, failure alarm nitrogen.
7. Fixed and mobile in the reservoir area can be used in different.

1. Ordinary PC (WinXP system) for data transmission and storage;
2. More than 200 meters distance data transmission, real-time observation to ensure that remote offices;
3. Flow, purity, boot time parameters such as figures show that the instrument calibration tips
4. Dynamic Display Technology
5. General Multi-function alarm (purity, fault, maintenance, etc.)
6. Online upgrade system

7. Three-level password protection (operating class / class director / manager level), to prevent the misoperation;

8. Analog paperless recording devices to adjust operating parameters online, adjust the parameters online Record interval;
9. Quick Start - the cold / hot start

10. Notice the three-tier maintenance tips / tips / protection of self-locking
11. Use, maintenance time Clear Record
12. Maintenance, shutdown countdown
13. Users to upgrade, adjust any parameters
14. Automatic shielding, the external environment to effectively prevent the interference of the control system
15. PDC energy-saving features (Pressure-Difference Control, matching)
16. PID output function of the flow (Proportion Integral Differential, matching)
17. Set aside the pressure, purity, traffic signal port connected with the user DCS system; reserved I / O contact and location PLC expansion module in order to make customers and remote monitoring and on-line network.
18. Reserved compressor temperature and pressure 4-20mA interface, and failure alarm switch interface to facilitate user to monitor the entire system.

Nitrogen system is mainly composed of three parts: compressed air, air purification, and distribution of nitrogen-oxygen separation;
Compressed air from the compressor to the 7.0-8.5Bar, by the purification system of three filters, refrigerated dryer and oil remover activated most of the air moisture, oil, and some particles of impurities removed for the back Host of the nitrogen gas source to provide a more secure supply.
Air into the nitrogen adsorption host two towers, the tower equipped with a dedicated high-performance oxygen and carbon molecular sieve, in accordance with its under the air pressure at the nitrogen and oxygen in different "Absorption of Choice" by the automatic switching valve implementation the two towers of the "pressure adsorption, desorption pressure release" the pressure swing adsorption process, namely: in the case of pressurized oxygen adsorption with molecular sieves to separate and nitrogen through the collection, transport; Absorption saturation automatically when switching to another Taga Absorption Absorption pressure, the tower is short and from the adsorption of oxygen, and so back and forth to create continuous high concentration of nitrogen.
