Carboblender - High Gravity Blending & Carbonization
The CarboBlender combines high-gravity blending (HGB) and carbonation in a single process step. High-gravity beer is blended with degassed water to adjust the desired final original gravity and/or alcohol content – and then carbonated inline with CO₂.
Application
Carboblending combines high-gravity blending (HGB) and carbonation in a single process step. This method allows for the production of different beers (brands) from one or a few base beers. As a result, brewery productivity increases with a comparatively small brewhouse capacity and a reduced number of fermentation tanks.
Uses in the brewery
If mixing and carbonation take place directly before the BBTs or even before the filler , production flexibility increases significantly. Different beers (brands) can be produced from the same mother beer – ideal for quickly responding to changing market demands.
This is how high-gravity blending works
For HGB, wort with a high extract content is produced.
During fermentation, this results in a beer with a higher original gravity and alcohol content.
Later in the process, this high-gravity beer is mixed with degassed water until the desired final value is reached.
Carbonization in the CarboBlender
For carbonation, the CarboBlender uses a specially designed vortex-Venturi injector . This injects carbon dioxide as a large number of very small bubbles directly into the product stream. Due to high pressure and turbulent flow, the CO₂ dissolves completely and homogeneously in a very short time.
Regulation & Process Control
At the end of the fermentation line is a control valve that maintains a constant pressure in the system, above the saturation pressure. Flow rates, as well as the original gravity and alcohol content, are continuously monitored and adjusted via a highly precise ratio control system . For this purpose, the system is equipped with high-precision flow meters and inline sensors from Centec.
