Product Description

0.1 Kw Food Grade Small Nitrogen Generation Equipment White For Cake Chips Packing




Working Principles


PSA means Pressure Swing adsorption . As we know there are about 21% oxygen and 78% Nitrogen in the compressed air . When O2 &N2 passing through the carbon molecular Sieve(cms)bed at a certain pressure ,The CMS will preferentially adsorb O2 than N2. N2 will go through as a product gas at pressure while A tower is in the adsorption phase ,B tower is de-pressuring at which time adsorbed O2 will be released to the atmosphere. The A,B tower cycle is then repeated .




Application of Nitrogen gas in food package area
Nitrogen gas as inert gas can be widely used as protection gas in lots of industry Such as medical ,Metal annealing ,Chemical fiber ,Tyre etc.For example in food package,our Generator can be equiped with your package machine ,and the N2 from our Generator can be directly filled in the package bag when you sealed.
1. N2 gas can remove the O2 in the package bag,make sure there is no O2 in the bag.So it can protect the food from oxidation and Exploration
2. The package with N2 gas can keep fresh product longer,Can protect the crisp food from broken during transportaion
3. Drinks ,beers and wine filled with N2 gas will keep fresh taste and appearance

What Is It and How Does It Separate Oxygen from Nitrogen

What is carbon molecular sieve? Carbon molecular sieve is an adsorbent that fuses the ideas

behind both activated carbon and zeolites into one product.

Activated carbon is known for its high porosity and zeolites are

known for their ability to be crafted into highly specialized

adsorbents called molecular sieve. Carbon molecular sieve is a

product that brings the benefits of both of these products together.Carbon molecular sieve is made out of coal (the same material

most activated carbon is made out of) and it specializes in

adsorbing material under 10 angstroms, something activated

carbon can not do accurately. The smallest pore size created for

carbon molecular sieve is 4A, but it exists in a 5A, and 10A (or 13X) as well.Carbon molecular sieve specializes in separating oxygen from nitrogen, an important part in natural gas processing.

This process is done with a PSA (Pressure Swing Adsorption)

device in two phases. The first phase sees the gas enter the PSA generator and the oxygen is adsorbed while the nitrogen passes

through because the nitrogen molecules are too large and are

used as a separate product.

The second phase sees the oxygen slowly released from the sieve at low pressures and thereby regenerating it so that the

separation process can be repeated.Carbon molecular sieve is used in this situation as opposed to activated carbon because the

physical size between oxygen (0.28nmأ—0.40nm) and nitrogen (0.30nmأ—0.41nm) molecules are so close.

The pore sizes on carbon molecular sieve are able to

accommodate these small size differences, where as activated carbon would just end up adsorbing both of them.Molecular sieve isn’t used because it is a polar adsorbent, meaning its surface area attracts other polar molecules.

Oxygen is a non-polar molecule and would be attracted to other non polar surfaces. Carbon molecular sieve is one of the few

non-polar adsorbents out there which is why it is chosen over

molecular sieve for this application.In addition to separating

nitrogen from oxygen carbon molecular sieve can be used for

metal heat treatment, electron production, and as preservative in

food product.
