Abstract

The whirlpool separator, which is a typical solid-liquid separation equipment, is one of the requested equipment in beer brewing. This study conducted by Computational Fluid Dynamics (CFD) technology examined the feed tube angles of 0~25° on the separation effect of whirlpool settling vat in order to find swing settlement regularity in the process. Results showed that, under the same feeding condition, the sedimentation effect could be improved by increasing incident angle within a certain degree. Nevertheless, increasing the incident angle to further degree would reduce the settlement effect. The result provides reference for structure design and optimization of whirlpool separator.
