The Carbonator is used for continuous injection of carbon dioxide into liquid food and beverages such as beer, sparkling wine, and soft drinks. A precisely defined and constant CO2 content is an essential quality feature of many products.



Technical Description – Carbonator


The Carbonator is designed for continuous injection of carbon dioxide into beer and beer-based mixed drinks. A precisely defined and constant CO2 content is an essential quality feature for carbonated beverages.

A Closer Look

For CO2 supply the Carbonator has a specifically designed Vortex-Venturi injector that feeds carbon dioxide in a very large number of very fine bubbles directly into the product stream. Due to high pressure and turbulent flow, the CO2 dissolves completely and homogeneously in a very short time. At the end of the dissolving path a control valve is installed. This valve keeps the pressure in the system constant and above the saturation pressure. The flows and the CO2 content are permanently monitored and automatically adjusted in the process. Therefore, the system is equipped with high precision flow meters and a CARBOTEC sensor made by Centec. Centec have decades of experience in the development and manufacturing of own precision instruments for CO2 control. The desired concentration of CO2 is precisely met in the carbonated product. The Carbonator is integrated into the CIP cleaning cycle of the main product line.
