Oxygen is a powerful gas in that it gives us the ability to sustain life, while at the same time, it is a key element in decreasing the shelf life of a product. In packaging, a gas flushing system is necessary for reducing oxygen levels with specific products. Rovema offers Aroma Perm as a solution.
It is a completely closed system that allows for residual oxygen levels as low as <1%
Any industry that needs a product protected from residual oxygen and is able to use an auger for filling.
Typically, we see this feature used in the coffee, tea, baby formula, powdered milk, and chemical industries.
This closed system features inlet ports and control valves to flush nitrogen into the auger hopper, forming tube, and optional horizontal cross feeder. Aroma perm features a compensation balloon that creates a closed system to prevent air from entering or leaving the hopper. There is also a control valve to flush nitrogen into a customer's supplied storage bin above the auger if applicable.
Working with a company that has the in-house capabilities to deliver an integrated solution greatly improves the chances of achieving the goals you seek. Rovema provides this uncomplicated pre-gassing solution. Conversely, using multiple sources can increase the risk of complications and failure to achieve your goals.
Trapped oxygen in the product determines the oxygen level of the packed product. Pre-gassing is extremely important because it lowers the oxygen level thereby preserving freshness.
Rovema provides an integrated pre-gassing solution that maintains the integrity of the package and helps to prevent oxidation of the product.
