South-Tek System's nitrogen generators can be used to produce nitrogen for the removal of contaminants through a process known as sparging. Also referred to as gas flushing, the process involves bubbling a gas through a liquid which helps helps remove contaminants thus protecting the integrity of products while reducing safety hazards. During the process, contaminants move toward the surface, with the gas, and are removed.
The food industry often uses nitrogen sparging to help remove atmospheric gases. Once removed, the inert atmosphere helps preserve food quality and increase product shelf life.
