A process is disclosed for managing or controlling fermentation product profiles in a parallel pair of beer product streams in which a brewer's wort is fermented to produce a beer having fermentation products therein. The beer is passed along a first side of a semipermeable membrane, under selective fermentation product passing conditions, to transfer selected fermentation products across the membrane, and into an unfermented beer wort on a second side of that membrane. This procedure results in the production of an unfermented wort having a permeate-supplemented fermentation product profile and a fermented wort having a permeate-reduced product profile. The unfermented wort is then itself fermented to produce a second fermented wort. The second fermented wort has a combination of fermentation-supplemented and permeate-supplemented fermentation product profiles. The respective fermented worts are then finished and-packaged for subsequent distribution and consumption.

Process for pre-conditioning brewer's wort with beer fermentation

A static mixer conduit comprises a longitudinally elongated conduit having tabs that are arranged with respective first edges adjacent the conduit wall and respective opposed second edges that are spaced radially inward from the conduit wall. These tabs are operable as fluid foils so that with fluid flowing through the conduit, greater fluid pressures manifest against the tab's upstream faces relative to reduced fluid pressures against their downstream faces. The resultant pressure difference in the fluid adjacent, respectively, the mutually opposed faces of each of the tabs causes a longitudinal flow of fluid through the conduit over and past each said tab to be redirected. As a result of the redirection, there is introduced a radial cross-flow component to the longitudinal flow of fluid through the conduit. In particular, the mixer further comprises a central body extending generally coaxially along at least a portion of the longitudinal extent of the conduit and defining between the central body's surface and the conduit wall an annular space confining the radial cross-flow. A method is also disclosed that comprises static mixing, over a longitudinal extent of a mixing volume having an annular cross-section, wherein radial cross-stream mixing in a longitudinal fluid flow results from flow-redirecting tabs redirecting a longitudinal fluid flow from an outer, fluid containment boundary surface, across an intervening space having an annular cross-section towards an inner boundary surface.

Static fluid flow mixing apparatus

A flow-through photochemical reactor includes a reactor body, that circumscribes a longitudinally extending channel having a generally annular cross section. This channel accommodates fluids passing between an inner wall of the reactor body and an outer wall of a photon-transmitting tube that is housed internally thereof. In addition, the reactor includes mechanically static, fluid-dynamic elements for passively inducing substantial turbulent flow within a fluid as it passes through the channel. This arrangement substantially increases the uniformity of the fluid's exposure to photons radiating from a source within the tube into the fluid an it is conducted through the channel.
