Purging

Ellenbarrie Industrial Gases deliver food-grade nitrogen and other inert gases that prevent or minimize the effects of oxidation. For example, Nitrogen is used to keep the Oxygen levels in and around the product low. An inert atmosphere stabilizes the product and increases its shelf life. Purging is one of the three main inerting applications improving product quality and longevity. Through purging, a gas such as nitrogen, carbon dioxide or argon is added to or bubbled through a food or beverage. This displaces atmospheric gases, replacing them with an inert atmosphere. Undesirable substances are eliminated, inhibiting and reducing unwanted chemical reactions with oxygen. As a result, food quality is preserved.
The atmosphere within process areas – for example in reactors – can be efficiently and cost-effectively purged of oxygen and moisture at start-up or shut-down with Nitrogen.

Filling and rinsing the processor with the dry gas is fully controllable. No pumps are needed so the risk of sparks and ignition or cross contamination is eliminated. What’s more, the use of nitrogen ensures ‘no reaction’ either with the substance previously stored or with what is still to come.
