Nitrogen Generator Useful for Fruit Storage Business
Nothing more excellent than eating fresh fruits. But when weather changes and fresh fruits are no longer available from farmers, then they come to our table thanks to fruit storage companies.
Do you know how these fruit storage companies keep fruits fresh? This is accomplished by controlled atmosphere (CA) storage that comprises a precise technology of controlling composition of gases in big rooms. Precise control of oxygen and carbon dioxide contents, temperature and humidity are important elements of this process. Keeping oxygen content at a certain level in the room is accomplished by injecting nitrogen gas, which is produced by a nitrogen generator. Storage of fruits in a controlled atmosphere is a non-chemical procedure which does not leave any harmful residues on the fruits.
ÖZAK GAS TECHNOLOGIES manufactures high quality nitrogen generators which are suitable for controlled atmosphere storage applications. ÖZAK also has the capability to design and implement the complete system for controlling the atmosphere of the room. You can contact them directly by clicking here for more information.
Food Grade Gases
Modified Atmosphere Packaging (MAP) is widely used to extend shelf life of food products. Some examples of food products that are most suitable for MAP are chips (potato, corn etc), nuts, and dairy and meat products.
Gases used most commonly for MAP are as follows:
- Pure Nitrogen
- Nitrogen - Carbon dioxide mixtures
- Nitrogen - Carbon dioxide - Oxygen mixtures
One way of procuring these gases is pre-mixed in gas bottles. However, this is a very expensive alternative especially in areas which are far away from gas filling centers since transport of heavy bottles to long distances cost much.
However, producing nitrogen with a nitrogen generator and making the gas mixture on-site is a very economical alternative to bottled gas, which will pay for itself in a very short time, even several months in some cases. Carbon dioxide is a low cost gas which can be procured locally in bottles almost everywhere.
ÖZAK GAS TECHNOLOGIES manufactures nitrogen generators and gas mixers which is all you need to make mixtures of the three gases mentioned above in any composition.
Importance of Measurement in Modified Atmosphere Packaging (MAP)
We use MAP to increase shelf life of food products we produce and invest a lot for this: special packaging machinery, special packaging material, gas production equipment etc. Very well. But can we be sure that no air is trapped inside the package after it is sealed?
It is possible that air can still exist inside a sealed package regardless how advanced MAP equipment we use. Likely reasons are:
- There may be a problem associated with gas source (nitrogen generator, gas mixing system, gas bottle etc)
- There may be a problem associated with packaging machine
- There may be human error
Naturally, if air exist inside a sealed package, the food product inside it will have reduced shelf life; investment and effort we made for MAP system will be useless.
There are measuring instruments specially developed for this purpose. You can see picture of two of them here.
Their usage is very easy: Just stab the sharp point of its probe into the package and press measuring button; you will see the composition of the gas inside the package in seconds.
Measurement should be made by sampling, ie one from every X number of packages. X should be determined by yourself.
These instruments are not very cheap but their cost is very small compared to your total investment in MAP equipment.
We do not sell these instruments, please do not ask:-).
