Dependent claims

Apparatus for mixing ingredients, said apparatus comprising, in combination:

a support selectively releasably supporting a receptacle having a bottom and side wall defining an interior and an opening communicating with said interior;
a lid having a top wall defining an aperture and a side wall extending downwardly from said top wall and defining a lid recess communicating with said aperture, said top wall positionable over a receptacle supported by said support;
lid placement means connected to said support for moving said lid relative to said support from an elevated position wherein said lid is not in engagement with said receptacle to a lower position wherein said lid positively engages and seals said receptacle to substantially close the opening of said receptacle and wherein said recess is disposed above the receptacle interior and in communication therewith;
a mixer shaft supported by said support and extending through the lid aperture, said mixer shaft and said placement means being separately and independently supported by said support and said mixer shaft being both axially and rotatably movable relative to said lid, to said support and to said receptacle and having a lower end;
a mixer head connected to said shaft lower end under said lid top wall;
transport means connected to said support for transporting said mixer shaft and mixer head downwardly within said receptacle after said lid has engaged said receptacle from a first position wherein the mixer head is disposed within said lid recess and above the receptacle interior to a second position wherein the mixer head is within the receptacle interior and closely adjacent to the receptacle bottom and for subsequently transporting said mixer shaft and mixer head from said second position to said first position;
and
rotating means including a drive motor fixedly connected to said support for rotating said mixer shaft and mixer head within said receptacle during transport of said mixer head between said first and second positions and while said mixer shaft moves axially through said lid aperture.
