Blender

A blender (sometimes called a mixer or liquidiser in British English) is a kitchen and laboratory appliance used to mix, crush, purée or emulsify food and other substances.

The newer immersion blender configuration has a motor on top connected by a shaft to a rotating blade at the bottom, which can be used with any container.

The blending container is generally shaped in a way that encourages material to circulate through the blades, rather than simply spinning around.

[citation needed] The Polish-American chemist Stephen Poplawski, the owner of the Stevens Electric Company, began designing drink mixers in 1919 under a contract with Arnold Electric Company, and patented the drink mixer in 1922[2] which had been designed to make Horlicks malted milkshakes at soda fountains.

He approached Fred Waring, a popular musician, who financed and promoted the "Miracle Mixer", released in 1933.

After the World War II other companies released more blender in Europe; the first one was the popular Starmix Standmixer (1948), from the Germany company Electrostar, which had numerous accessories, like a coffee grinder, cake mixer, ice cream maker, food processor, thermic jar, milk centrifugue, juicer and meat grinder; and the Braun Multimix (1950) from Max Braun, which had an attachment with glass bowl to make batter bread and a juicer centrifuge like the one developed by Turmix.

Using the same marketing strategy as Turmix in Europe, Walita passed the million-blenders-sold mark a few years later in the early 1950s.

Later in 1997 Arno was bought by the Groupe SEB, owner of Moulinex, T-Fal, Rowenta, and other home appliance brands.

[citation needed] With the rising popularity of smoothies, Frappucinos and other frozen drinks prepared in front of the customer, new models of commercial blenders often include a sound-reducing enclosures and computerized controls.

[citation needed] Specialized blenders for making smoothies are becoming popular, chiefly resembling an ordinary model with a spigot added for quick serving.

In 2010 the United States court system concluded that Vita-Mix had willfully infringed the patents, ultimately awarding Blendtec $24 million in damages.

Usually, a small rubber washer provides a seal around the output shaft to prevent liquid from entering the motor.

Each different combination of energized windings produces a different torque from the motor, which yields a different equilibrium speed in balance against the drag (resistance to rotation) of the blade assembly in contact with the material inside the food container.

[10] The sales pitch lasted for 25 minutes, suggesting that the blender be used to make bread crumbs, potato pancakes, laxative spinach drinks, and a dessert beverage featuring entire raw eggs and their shells, which the host announced would be enjoyed like malted milk.
