VeGaS  

Principle

The Centec vacuum deaeration system VeGaS is a modular skid using a vacuum vessel for the removal of oxygen and other gases from a wide range of liquid products such as soy milk or tomato ketchup. The presence of even low oxygen levels can increase microbial activity and adversely affect taste, colour and shelf life of beverages and food products. Through special dispersion nozzles the liquid is sprayed into a continuously evacuated vessel. Due to the distribution of the fine liquid droplets, the transfer surface area between the liquid and the vacuum is maximized. The large partial pressure difference of O2 forces the oxygen out of the liquid into the vacuum. This fundamental scientific principle is described by “Henry’s Law”. Once the oxygen has been removed, it transfers out of the vessel through the vacuum line. The deaerated product collects at the bottom of the tank from where it is discharged for further processing. Vacuum deaeration can be assisted by a strip gas like nitrogen or carbon dioxide. O2 content monitoring with highly accurate OXYTRANS optical sensing technology developed and manufactured by Centec can be added, as can various other options.
