Food mixer incorporating an archimedean screw and cutting blades

A food mixer, comprising:

• a base and a container, said container having an open upper surface through which food material can be placed into or removed from said container, said container being provided with a screw impeller having a continuous flight, said screw impeller being located within an open topped sleeve adjacent a lower surface of said container and further including enlongated cutting blades extending radially from said screw impeller between adjacent turns of said flight, the open topped sleeve having at least one opening in a lower end thereof so that food material can enter the open topped sleeve through the opening, said container being removably connected to said base, with said base including a motor capable of rotating said screw impeller via driving means passing through said container in a sealed relationship therewith, so that when said screw impeller is in motion, food material enters a lower portion of the open topped sleeve and exits its upper surface after mixing and circulates between sides of said container and outside of said sleeve, said open topped sleeve sufficiently encasing said screw impeller for permitting a safe insertion of a food implement into said container while said screw impeller is in motion.
