Inline processing of ready-to-drink beverages

The Heidelberg Inline Mixer from INDAG can be used to continuously fill and mix both carbonated and non-carbonated beverages. One characteristic feature of inline mixing is the precise and quantitative proportioning of the individual components. The Inline Mixer is available as a two-component or multi-component mixer.

Both systems are based on the inline mixing principle. The difference is that, for the two-component mixer, all beverage components are prepared in a single pre-blend. These are then added to the water stream as syrup. As for the multi-component mixer, there is no pre-blending: All components are added simultaneously and continuously. Both the two-component and the multi-component mixer have an integrated, vacuum-based water de-aerating system, integrated component dosing and carbonization as well as a pressure tank. With water de-aerating, the oxygen content in the production water is reduced to prevent quality losses through oxidative processes in the final beverage.

This also makes the Heidelberg Inline Mixer ideal for production of oxygen-sensitive beverages e.g. for sports and wellness drinks, mixed beer drinks, etc. The syrup or individual beverage components are continuously pumped into the water stream through the dosing pumps and a flow meter. Carbonisation is proportional to the final beverage stream. A static mixer is also integrated to ensure fine CO2 sparkling in the final drink, which is then pumped into a pressure tank. The pressure tank also helps adjust capacity at the filling line. When designing a multi-component mixer, possible enhancement options should be considered right from the beginning e.g. enhancement with dosages of functional additives. With inclusion of a dosing connection for beer, wine, etc. mixed alcoholic drinks such as alcopops can also be prepared.
