CO2 is injected into the beer via the GDI gas injector developed by corosys. The gas injector splits the CO2 into very small bubbles and ensures that the CO2 completely dissolves in a very short time. The system works without using a static mixer. The homogeneous dispersion and the absence of gas bubbles can be monitored by a sight glass situated at the outlet of the dissolving path.
The CO2-content is continuously measured in-line at the outlet of the unit. The product specific set point is compared with the process value and the CO2 flow is adjusted accordingly by a control algorithm. The control valve, which is located at the end of the dissolving path, keeps the pressure in the system constant, even if the flow is unsteady.
The unit can be controlled by a local PLC with a touch panel or by a process control system.
Designed for high hygienic standards, all common cleaning agents in the brewing and beverage industry can be used for CIP cleaning.
