System and method for extracting soluble flavor components in brewing liquor from solid flavor carrier material

摘要

The present invention relates to a system (1) and method for extracting soluble flavor components from a solid flavor carrier material into a brewing liquor. The system (1) comprises a process vessel (2) and a filtration device (3). The process vessel (2) comprises an inlet (2a) for the solid flavor carrier material, a circulation inlet (2b) for the material containing brewing liquid, and a circulation outlet (2c) for the material containing brewing liquid. The filtration device is configured to separate solid components from the material containing brew, including at least one cross-flow filter (3a), a circulation inlet (3b) for the material containing brew, and an unfiltered material containing brew. It is a cross-flow filtration device including a circulation outlet (3c) for use and an opening / closing outlet (3d) for a brewing liquid containing a filtered material. The process vessel and filtration device are included in the recirculation loop (4). Moreover, the system comprises a recirculation pump (5) and an open / close supply port (4c) for introducing the material containing brewing liquid into the recirculation loop (4).
