Nitrogenator  

Principle

The Centec Nitrogenator is a modular skid which uses either one or several specifically designed Vortex injectors, or alternatively highly effective membrane contactors to reach exactly the required value of dissolved N2 in the beverage. The Vortex nozzles inject the gas as fine bubbles into the liquid stream. They ensure that the N2 dissolves perfectly and absolutely homogeneously in a very short time. Each contactor contains thousands of microporous hydrophobic hollow fibre membranes. Their large internal surface maximizes the contact area between liquid and gas. While N2 is applied on the inside of the hollow fibres, the beverage flows in counter current on the outside. With a high partial pressure difference between the liquid and N2 gas, the N2 permeates through the membranes into the beverage. This fundamental scientific principle is described by “Henry’s Law”. At the outlet of the system the N2 content is permanently measured with a highly reliable sensor. Based on this accurate in-line measurement, the N2 flow is instantly and fully automatically adjusted. The modular design of the process units allows for easy expansion, e.g. for blending or additional carbonation.
