Patent ID: 8678639

Claim:
A mixing machine comprising: a mixing head having at least one element for connecting the mixing head to a container containing a mix to form a closed mixing receptacle containing the mix; said mixing head pivotably mounted relative to a frame such that the mixing receptacle formed from the mixing head and container can be pivoted to execute the mixing process; said mixing head having a mix stream producing device and at least one rotary-driven mixing tool interacting in a mix stream; the mix-stream-producing device producing a low-energy primary mix-stream functioning as a feed stream to supply the mix contained in the mixing receptacle to the at least one mixing tool; the at least one mixing tool interacting in the primary mix-stream to produce a secondary mix-stream, which performs the actual mixing process, as a cross-stream to the primary mix-stream, the secondary mix-stream containing only a fraction of the mix contained in the mixing receptacle; the mix-stream-producing device is a rotary-driven, container-scraper feed tool which produces a primary mix-stream that moves concentrically to a rotational axis of the feed tool, said container-scarping feed tool having at least one paddle; and the at least one mixing tool is positioned between a travel path of the paddle of the feed tool and a shaft of the feed tool.
