A blender for mixing beverages that has a cylindrical upright, substantially closed, frustoconically bottomed blending bowl with an intake port at the top and a discharge port at the outer edge of the bottom of the bowl. A motor driven impeller is mounted for rotation about a longitudinal axis in the bowl and has blades projecting radially therefrom for coaction with stationary blades that extend inwardly from the bowl wall. One stationary blade is located just past the discharge port in the direction of impeller rotation to force the contents out the discharge port, which is located within the longitudinal extent of the stationary blades for this purpose. The impeller blades have edges complementary to the stationary blade edges and inclined with respect thereto and in a direction to direct the contents longitudinally toward the discharge port, for which latter purpose the impeller blades have bottom edges that are complementary to the sloping bottom wall. In an alternative embodiment, the blending bowl and impeller are horizontally disposed with the intake port at the rear end and the discharge port at the bottom of the front end, and the bowl being forwardly radially enlarged to facilitate advancement of its contents. The intake port is laterally offset in the direction of impeller rotation and a radially inwardly extending baffle plate is provided laterally opposite the inlet. The impeller blades are triangularly shaped and the stationary blades are complementarily triangularly shaped with one stationary blade just past the discharge port in the direction of impeller rotation.
A blender for mixing liquids, liquids and powders, or similar products, said blender comprising a substantially closed blending bowl having spaced intake and discharge ports, an impeller mounted in said bowl for rotation about a longitudinal axis and having radially extending blades disposed intermediate said intake and discharge ports, means for rotating said impeller, and longitudinally extending stationary blades extending radially inwardly from said bowl into close proximity to said impeller blades for cooperation therewith, one of said stationary blades being disposed adjacent said discharge port and past said port in the direction said impeller advances product, said one blade thereby obstructing advance of the product past said discharge port to facilitate discharge of product through said discharge port.
A blender for mixing liquids, liquids and powders, or similar products, said blender comprising a substantially closed blending bowl generally vertically disposed and having a bottom wall, an intake port adjacent one end of said bowl and a discharge port adjacent the other end thereof, said discharge port being disposed adjacent the outer edge of said bottom wall and said bottom wall sloping downwardly toward said outer edge thereof, an impeller mounted in said bowl for rotation about a generally vertical longitudinal axis and having radially extending blades disposed intermediate said intake and discharge ports and extending over said bottom wall, and means for rotating said impeller.
