Carbon Molecular Sieve for Food Preservation

Carbon Molecular Sieve for Food Preservation


Xintao Food Preservation Special Carbon Molecular Sieve CMS-240

Nitrogen is an inert gas, which effectively inhibits the survival of pests and diseases in the process of grain storage. Nitrogen is also widely used in green grain storage, food nitrogen-filled packaging, vegetable preservation, wine sealing (canning) and preservation, and seafood preservation. , insect control, nitrogen sealing, etc.

Food Preservation Nitrogen Generator is a high-purity nitrogen generator specially designed for the food packaging and preservation industry according to the advanced PSA pressure swing adsorption principle, using carbon molecular sieve to separate nitrogen and oxygen from the compressed air. Provide dry and continuous pure nitrogen for food packaging, beverage stirring, fruit and vegetable storage, cereal fumigation, food nitrogen puffing and other purposes , energy saving and so on.

Working Principle

Using the diffusion and adsorption principle of carbon molecular sieve, the air is compressed to 0.7-0.8Mpa and enters the pressure swing adsorber for oxygen and nitrogen separation. When the pressurized compressed air enters the adsorbent (carbon molecular sieve), the diffusion rate of oxygen is higher than that of nitrogen. The diffusion speed is fast, so oxygen first enters the carbon molecular sieve, nitrogen stays on the surface of the carbon molecular sieve, and the carbon molecular sieve has a certain adsorption capacity for oxygen. The nitrogen that has not been diffused and adsorbed into the carbon molecular sieve is discharged from the outlet of the adsorber. When the pressure is reduced, the oxygen diffused and adsorbed in the carbon molecular sieve is desorbed and emptied, and the adsorbent is regenerated.

Food Requirements for Nitrogen

The food industry does not have high requirements for nitrogen, many with a purity of more than 98% can meet the requirements, and the pharmaceutical industry usually requires nitrogen with a purity of 99.99%.

Xintao Food Preservation Special Carbon Molecular Sieve CMS-240 Features:

1. Low cost: The PSA advanced process is a simple method of nitrogen production. It generates nitrogen within a few minutes after starting the machine, and the energy consumption is low.

2. Stable nitrogen purity: monitored and displayed by the instrument to ensure the required nitrogen purity.

3. Xintao Food Preservation Special Carbon Molecular Sieve CMS-240: It has the characteristics of large adsorption capacity, strong compressive performance and long service life
