DeCarbonator - Decarbonization & Carbonization

The decarbonizer is a membrane system for continuously adjusting the CO₂ content in the product – including targeted reduction . Simultaneously, the oxygen (O₂) content is reduced. The system is designed for stable operation with a constantly monitored CO₂ level and regulates the CO₂ flow directly and fully automatically .

Application

The decarbonizer is designed for the continuous adjustment and, in particular, the reduction of the CO₂ content in:

Beer
Beer-based mixed drinks

A precisely defined and consistent CO₂ content is a crucial quality characteristic for carbonated beverages.

Principle – Membrane technology (hollow fibers)

CO₂ adjustment is achieved via highly efficient membrane modules :

Each module contains thousands of hydrophobic , gas-permeable hollow fiber membranes .
The large membrane surface maximizes the exchange area and contact time between product and gas.
CO₂ is applied to the inside of the hollow fibers, the product flows countercurrently on the outside between the fibers.
Depending on the CO₂ partial pressure difference, CO₂ migrates through the membrane:

– from the membrane into the product (increase CO₂)

– or from the product into the membrane (reducing CO₂)

The underlying principle is described by "Henry's Law" .

Measurement & automatic control (CO₂ / O₂)

The CO₂ content in the carbonized product is constantly monitored.
The system is equipped with a highly accurate CARBOTEC sensor from Centec for process control .
Based on the in-line measurement, the carbon dioxide flow is adjusted immediately and fully automatically .
The O₂ content is measured using proven optical OXYTRANS sensor technology from Centec.
