A blender (occasionally liquidiser in British English and occasionally vitamiser in Australian English) is a kitchen appliance used to mix  ingredients or puree food.
Blenders are also used  to prepare emulsions, such as mayonnaise,  and cream soups.
Blenders are to be distinguished from lower-speed hand-powered or  electric mixers  that are used for mixing applications.
The term typically refers to a  stationary, upright electrical device, but hand-held immersion blenders have become common in recent years.
Blenders are also used in laboratory applications._________
The blending container can be made of glass, plastic,  stainless steel, or porcelain, and often has graduated markings 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 or gasket  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._________
The hand-held immersion blender 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 processors. In particular, thicker mixtures such as mayonnaise and hummus are conveniently made in food processors.
