Stripping oxygen out of edible oils (vegetable oils).
Objective: Reduce costs by extending life cycle of oil
- Oxidation contributes to rancidity of edible oil
- Sparging with nitrogen reduces oxygen levels and minimizes oxidation
Oxidation in oils reduces the product's shelf life. Traditionally, oxygen is stripped out of edible oils to protect them and increase shelf life. The old-fashioned process consisted nitrogen being pumped through 1mm drilled holes in pipes, acting as the sparger. Nitrogen bubbles were around 6mm in diameter. This was inefficient, as the larger the bubble, the more time and nitrogen was needed in the process. GKN porous metal sparger elements utilizing a 3 micron nominal pore size to create nitrogen bubbles around 50 to 100 microns. This increases the surface area of the gas in the product 40x (depending on the gas exit velocity). This process saves a significant amount of process time and 40-50 percent of Nitrogen gas usage.
