Softdrink Mixing CSD

The two- and multi-component mixing system CSD continuously and precisely produces carbonated soft drinks as well as sugar free beverages. It combines the process steps of degassing, mixing, cooling and carbonisation into one compact system. The preassembled and tested unit can be packed into a container and quickly installed and put into operation on-site.

The system is characterised by its highly flexible production options and its performance. The entire portfolio of soft drinks can be produced in a wide capacity range from 40 to 100%. High accurate, state of the art instruments monitor and control the essential quality parameters and guarantee the highest product quality.

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.
