The DeCarbonator is used for continuous adjustment and especially reduction of the CO₂ content of liquid food and beverages such as beer, sparkling wine and soft drinks.

Highly efficient membrane modules allow the CO₂ concentration to be increased and decreased with extraordinary accuracy. At the same time the oxygen content is reduced. Each module contains thousands of hydrophobic, gas permeable hollow fibre membranes resulting in a large surface. This large surface maximizes the transfer area and the contact time between product and gas.

While CO₂ is applied on the inside of the hollow fibres, the product flows in counter current between them on the outside. Depending on the CO₂ partial pressure difference between product and gas, the CO₂ permeates through the membranes either out of the membranes into the product or out of the product into the membranes.

The CO₂ content of the carbonated product is permanently monitored by a high precision CARBOTEC sensor made by Centec. Based on this inline measurement, the CO₂ flow is fully automatically adjusted.
