High-gravity blending involves producing wort with a high extract content. During fermentation, this results in a beer with a higher original gravity and alcohol content. Later in the process, the high-gravity beer is blended with degassed water to achieve the desired final original gravity and/or alcohol content. When this occurs directly before the BBTs (Bullet Blowers) or even before the filler, the brewery's flexibility is significantly increased. Different beers (brands) can be produced from the same mother wort. This allows the brewery to respond quickly to changing market demands. For carbonation, the CarboBlender features a specifically designed vortex-Venturi injector that feeds carbon dioxide in a very large number of very small bubbles directly into the product stream. Due to the high pressure and turbulent flow, the CO2 dissolves completely and absolutely homogeneously in a very short time. A control valve is located at the end of the dissolution section. This valve maintains a constant pressure in the system, above the saturation pressure. The flow rates and the original gravity and alcohol content are constantly monitored and adjusted via highly precise ratio control. For this purpose, the system is equipped with high-precision flow meters and in-line sensors from Centec. Centec has decades of experience in the development and manufacture of its own precision instruments for controlling alcohol and CO2.

Carboblender - High Gravity Blending & Carbonization
Carboblending combines high-gravity blending (HGB) and carbonation in a single process step. This method makes it possible to produce 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.
