In today’s world, sustainability is more critical than ever, and companies are looking for innovative ways to reduce their environmental impact. JBT provides an ingenious solution to help customers fill oxygen-sensitive liquid products sustainably: Nitrogen Volume Displacement (NVD).

Recently a new generation of the NVD module was launched to provide customers with a sustainable option for filling oxygen-sensitive products into bottles. The new generation improves sustainability by reducing nitrogen consumption, while maintaining the same level of product quality and safety for oxygen-sensitive products. According to Bram Baars, Sr. Mechanical R&D Engineer at JBT, “The new generation NVD for AsepTec Fillers is an excellent example of how sustainability can drive innovation.”

We developed a solution that improves product quality and safety and reduces environmental impact.

The Need for Low Oxygen in Liquid Food Filling

JBT AsepTec Fillers are used to aseptically fill liquid food products into bottles. Some products, such as juices, plant-based products, and nutraceuticals require a low oxygen environment to prevent oxidation of valuable ingredients. To address this need, JBT offers oxygen reducing modules as an option. The modules displace the air mixture with nitrogen.


“The oxygen reducing modules include several key components that work together to create a more sustainable filling process.” explains Antonio Martinez, Aseptic Customer Care Manager. “By using empty bottle flushes, headspace flushes, and protective nitrogen blanketing, we can minimize the amount of oxygen in the package, while not jeopardizing aseptic performance and operator safety.”

The empty bottle flush prevents foam bubbles on top of the product from being filled with air by flushing the empty bottle with nitrogen. The headspace flush then flushes the area above the product with nitrogen just before applying a screwcap or foil lid. The protective nitrogen blanketing replaces the air volume displacement between filling and cap applications with nitrogen volume displacement (NVD).

Reducing Nitrogen Consumption in Aseptic Liquid Filling

The new generation NVD system has reduced the aseptic zone area with nitrogen downflow by 50%, resulting in reducing the nitrogen consumption by 50% as well.

Also new is that the downflow can be a mixture of nitrogen and compressed air, adjustable on the HMI (Human Machine Interface). Customers can adjust the mixture to product quality requirements, reducing nitrogen consumption even more when the product is less oxygen sensitive.

JBT's NVD Retrofit Benefits

“One of the main benefits is the ability to reduce nitrogen consumption during the filling process while maintaining the aseptic conditions.” says Bram Baars. “By optimizing the mixture of nitrogen and compressed air to product requirement, our customers are able to achieve significant reductions in nitrogen consumption, while maintaining the required oxygen reduction in the final package”

“The NVD improvement is not only an option for new machines, but it can also be retrofitted to existing AsepTec Fillers with an NVD module,” says Antonio Martinez. “This means that customers can take advantage of sustainability benefits of the NVD system without the invest for a completely new machine.”
