In an apparatus for blending and kneading ingredients comprising an open-topped container for the ingredients to be blended and kneaded into a cohesive mass, such as dough, a lid for the container, rotary drive means mounted on the lid, and a kneader arm removably mountable to the rotary drive means for rotatable drive thereby, the improvement comprises means for mounting the lid so as to enable limited angular movement of the kneader arm axis within the container for enabling the axis of rotation of the kneader arm to sweep across the container bottom during rotation of the kneader arm as the viscosity of the mixture of ingredients being kneaded increases. This is achieved by using interengaging parts on the lid and container, preferably lugs on the lid and handles on the container, which allow for rocking and elevational movement of the lid. Preferably a flexible lid is utilized, and experiences an undulating movement enhancing the angular movement of the kneader arm axis.
Apparatus for kneading ingredients into a mixture having an associated viscosity, comprising an open-topped container for said ingredients, support means capable of bridging the open top of the container, and interengaging means carried by the container and the support means for removably securing the support means on the container and for resisting forces tending to rotate the support means relative to the container, rotary drive means including an electric motor carried by said support means, and a kneader arm drivable by said drive means for rotation in the container about an axis of rotation, said kneader arm being supported solely at its upper end by said drive means and being otherwise free for movement relative to the container, said container having a bottom, said interengaging means and support means in combination comprising connection means between said container and said rotary drive means for enabling both rotation of said kneader arm about said axis of rotation and angular displacement of said axis of rotation with respect to said container bottom during said rotation for enabling the axis of rotation of the kneader arm to sweep over said container bottom during rotation of said kneader arm.
A kneader arm for use in an apparatus for kneading ingredients into a mixture having an associated viscosity comprising an open-topped container for said ingredients, support means capable of bridging the open top of the container, and interengaging means carried by the container and the support means for removably securing the support means on the container and for resisting forces tending to rotate the support means relative to the container, rotary drive means including an electric motor carried by said support means, said kneader arm being drivable by said drive means for rotation in the container about an axis of rotation and being supported solely at its upper end by said drive means and being otherwise free for movement relative to said container, said container having a bottom, said interengaging means and support means in combination comprising connection means between said container and said rotary drive means for enabling both rotation of said kneader arm about said axis of rotation and angular displacement of said axis of rotation with respect to said container bottom during said rotation for enabling the axis of rotation of the kneader arm to sweep across said container bottom during rotation of said kneader arm as the viscosity of the mixture of ingredients being kneaded increases;
