Our de-alcoholisation plants are designed to produce a highly de-alcoholised beer and rectified alcohol with minimum adverse side effects on beer quality. Additionally, the design is flexible regarding product flow and composition and well-suited for non-filtered beer. Therefore, it is a sustainable investment enabling a brewery to serve all current or future market trends.
The flexible design suits various product flows and compositions and is also well-suited to non-filtered beer. Therefore, it is a sustainable investment enabling a brewery to serve all current or future market trends.
Firstly, the beer is gently degassed in order to avoid foaming throughout the process. The temperature of the incoming product is adjusted in counterflow to the outgoing de-alcoholised beer. In a special Bucher Unipektin degassing system, very low final gas levels are achieved at a pressure slightly below the boiling pressure. The alcohol is then removed from the beer and rectified in a unique column. The column consists of two sections: a first section for stripping the alcohol out of the beer and a second section for rectifying the alcohol to the desired concentration. The unique design employed in the high precision inserts provides several advantages:
minimum pressure drop allows a low temperature at the bottom of the column with least impact on beer quality and optimised energy consumption compared to similar systems
high tolerance for suspended particles enabling trouble-free processing of non-filtered beers
