The beverage water is degassed in a column under normal pressure by stripping with CO2 to residual oxygen values below 50 ppb. Here, the water is pre-carbonised with approx. 2 g/l CO2.
Multi-components such as single syrup, raw materials and flavors can be added continuously and inline to the water or a finished syrup can be produced in a mixing tank, which is then added to the water as a two-component system.
The syrup is metered inline into the water via a special valve combination. The water-syrup ratio is adjusted by means of a high-precision mass flowmeter and a control valve it is monitored and readjusted by the integrated °Brix measurement and control. Afterwards a centrifugal pump ensures optimum mixing of syrup and water. Optionally, the blended product can now be cooled.
During the subsequent carbonation, CO2 is injected in a constant ratio into the beverage. The corosys GDI injector ensures the complete dissolving of CO2 without any static mixers in the product pipe. In the outlet of the surge tank, the essential quality parameters, the CO2 content and °Brix are accurately measured and monitored. Only the finished product that meets all quality requirements is released for filling. A product recycling from the buffer tank to the syrup dosage allows adjustment of CO2 and °Brix at the system startup. Syrup and product losses are thus avoided.
Designed for high hygienic standards, the mixing system is suitable for all typical CIP agents used in the beverage industry and is fully CIP capable.
