Blender (device)

A blender is a kitchen appliance used to blend ingredients or puree food. The term typically refers to a stationary, upright electrical device, which is to be distinguished from a hand-powered or electric mixer that may be used for similar purposes.

A typical blender will be built around a vessel for the ingredients to be blended. At the top of the vessel will be a cap to prevent ingredients from escaping when the blender is switched on. At the bottom will be a blade assembly, typically removable for cleaning purposes. The bottom seal will most likely be watertight. The vessel will rest upon a base containing a motor (for turning the blade assembly) with controls on its surface. Most modern blenders will offer a number of possible speeds.

In 1922, Stephen Poplawski invented the blender. Stephen Poplawski was the first to put a spinning blade at the bottom of a container. He used his appliance to make soda fountain drinks. In 1935, Fred Osius improved on Poplawski's idea and invented the famous Waring Blender.
