Method and device for adding hops to a fermentation vessel

Assembly for regulating flow of hops into a fermentation vessel includes a hollow cross-shaped connector including a first cylindrical housing intersecting a second cylindrical housing at an approximate right angle. A rotary shaft coaxially mounted within the first cylindrical housing supports a hub and uniformly spaced vanes at a proximal end with outer ends of each vane adapted to sweep in close engagement with an inner wall of the first cylindrical housing. An actuator coupled to a distal end of the shaft is configured to control rotation of the shaft to control flow of hops from a hopper configured for holding hops into a hatch of a fermentation vessel configured for holding fermenting fluid. An outlet of the second cylindrical housing sealably connects to the hatch of the fermentation vessel, and an inlet of the second cylindrical housing sealably connects to an aperture of the hopper.
