Construction

 for approximate measuring purposes. At the top of the container is a lid to prevent ingredients from escaping during operation. At the bottom is a blade assembly, sometimes removable for cleaning purposes. In cases where the blades are removable, the container should have an o-ring

An O-ring, also known as a packing, or a toric joint, is a mechanical gasket in the shape of a torus; it is a loop of elastomer with a disc-shaped cross-section, designed to be seated in a groove and compressed during assembly between two or more parts, creating a seal at the interface.The O-ring...

 between the body of the container and the base to seal the container and prevent the contents from leaking. The blending container is generally shaped in a way that encourages material to circulate through the blades, rather than simply spinning around.

The container rests upon a base that contains a motor for turning the blade assembly and has controls on its surface. Most modern blenders offer a number of possible speeds. Low-powered blenders require some liquid to be added for the blender to operate correctly. This is because the liquid is used to move the solids around the jar and bring it in contact with the blade as the "whirlpool" fluid movement brings items from the top to the bottom. High-powered blenders are capable of milling grains and crushing ice without such assistance.

 has no container of its own, but instead has a mixing head with rotating blades that can be immersed in a container. Immersion blenders are convenient for homogenizing volumes that are too large to fit in the bowl of a stationary blender or, as in the case of soups, are too hot to be safely poured into the bowl.

Some of the functions of blenders have been taken over by food processor

North America

The Polish-American Stephen J. Poplawski, owner of the Stevens Electric Company, began designing drink mixers in 1919 under contract with Arnold Electric Company, and patented the drink mixer in 1922 which had been designed to make Horlicks

, a popular musician who financed and promoted the "Miracle Mixer", released in 1933. However the appliance had some problems to be solved about the seal of the jar and the knife axis, so Fred Waring redesigned the appliance and released his own blender in 1937, the Waring Blendor with which Waring popularized the smoothie

, introduced a product called "The Blender," which was functionally a reinforced blender with a stainless steel jar, instead of the Pyrex glass jar used by Waring.

Europe

In Europe, the Swiss Traugott Oertli developed a blender based on the technical construction and design style conception of the Waring Blendor, releasing in 1943 the Turmix Standmixer. Based on the blender, Mr. Traugott also developed another kind of appliance to extract juice of any juicy fruit or vegetables, the Turmix Juicer, which was also available as separated accessory for use in the Turmix blender, the juicer Turmix Junior. Turmix had promoted the benefits of drinking natural juices from fruits combined with other vegetables, beyond a sort of recipes using juices to promote its blender and juicer.

South America

In Brazil, Waldemar Clemente, ex-staffer of General Electric and owner of Walita electric appliance company since 1939, designed a blender based on the Turmix Standmixer and released in 1944 the Walita Neutron blender. Clemente also created the name liquidificador, which ever since designated a blender in Brazil. Near after, Walita acquired the Turmix patents in Brazil and also released the Turmix juicer, designated it as Centrífuga Walita as well the others Turmix accessories for use with the blender motor, as fruit peelers, grinder, crusher and batter mixer. Using the same marketing strategy as Turmix in Europe, Walita passed the million-blenders-sold mark a few years later in the early 1950s. Walita were the first manufacturer to release a wide range of blenders in the 1940s. In the 1950s, Walita made blenders for Siemens, Turmix, Philips, and Sears (Kenmore), among others. In the 1960s Royal Philips Co. approached Walita, acquiring the company in 1971, becoming Rpyal Philips' kitchen appliances developer division specializing in blenders, which are sold under the Philips brand outside Brazil.

The Austrian immigrant Hanz Arno, owner of an electric motor manufacturer in Brazil since the 1940s, released a blender in 1947, based on the blenders made by Hamilton Beach and Oster. The Liquidificador Arno was exported to other South American countries. As Arno had stocks of Electrolux, that brand was used on the blender in some countries. Later in 1997 Arno was bought by the SEB Group, owner of Moulinex, T-Fal, Rowenta, and other home appliance brands.
