Deaeration of Beverage Water
Oxygen in beverages can affect taste and can reduce shelf-life and product quality, so using deaerated water for beverage manufacture is important to help minimize the amount of oxygen in the final product.
GEA offers a range of water deaeration systems, and the GEA DIOX-2 represents an ideal two-stage vacuum deaeration unit for producing deaerated beverage water for both still and carbonated drinks. Dependent on your downstream process, and your expected residual oxygen value, the GEA DIOX-2 water deaeration system can be easily integrated into existing systems.
Two-stage vacuum deaeration for minimizing residual oxygen
The first stage of the deaeration process extracts the bulk of the oxygen using vacuum deaeration. Next, CO2 is added in to this pre-deaerated water - to promote the release of oxygen - and the water is transferred to the second stage of the process, where the CO2-oxygen mixture is drawn out by means of a vacuum pump. A discharge pump then carries the deaerated water to the next process stage.
Sealing water consumption is reduced by the integrated temperature control and can optionally be equipped with a sealing water cooler to minimize water losses.
The system is cleaned via the product path.
Features of the GEA DIOX-2 water deaeration system:
- Suitable for generating water with residual oxygen content of ≤ 0.05 mg/l (≤ 50 ppb)
- Low CO2 consumption
- Low operating costs
- Pre-assembled unit, so short installation time
- Low maintenance costs
- The CO2-free deaerated water is suitable for non-carbonated beverages
- Configurable for flow rates of between 50 hl/h and 900 hl/h
- Compact system with relatively small footprint and low height requirements compared with other deaeration systems
- Simple integration into existing systems
- Low energy demand for system operation

The breakthrough that changed spray drying
In 1976, NIRO engineers responded to a competitive challenge by rethinking what spray drying could do. Their idea became the multi-stage dryer MSD. Fifty years later, the same fundamental principle helps turn liquids into the powders used in essential nutrition products and important medicines around the world. Refined through decades of engineering expertise, customer insight and continuous development, MSD is a story of innovation with lasting impact.
Beyond the machine: unlocking better plant performance
An efficient machine does not automatically make an efficient factory. Real improvement often starts by looking beyond individual equipment and understanding how processes, energy systems and operating decisions affect one another. It’s a holistic approach designed to uncover opportunities that might otherwise be missed.
How a valve reshapes the way food and drinks are made
In food and beverage plants, valves are commonly operated using compressed air. GEA Hydract® Actuation Technology moves valves with water instead, in a closed, digitally controlled circuit. The result is a valve that can be held exactly in place and steered in fine-tuned steps. This results in lower energy use and greater control.
