Characteristics




Different blenders have different functions and features but product testing indicates that many blenders, even the less expensive ones, are useful for meeting many consumer needs. Features which consumers consider when purchasing a blender include the following:

  • large visible measurement marks
  • ease of use
  • low noise during usage
  • power usage (typically 300–1000 watts)
  • ease of cleaning
  • option for quick "pulse" blending

Countertop blendersedit

Countertop blenders use a 1–2 liters (4–8 cups) blending container made of glass, plastic, stainless steel. Glass blenders are heavier and more stable. Plastic is prone to scratching and absorbing the smell of blended food. Stainless steel is preferred for its looks, but limits visibility of the food as it is blended.

Countertop blenders typically offer 3–16 speed settings, but having more choices in speed settings is not an indication of increased utility for all users.

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 the addition of some liquid to operate correctly. In these blenders, the liquid helps move the solids around the jar, bringing them in contact with the blades. The blades create a whirlpool effect which moves solids from top to bottom, ensuring even contact with the blade. This creates a homogeneous mixture. High-powered blenders are capable of milling grains and crushing ice without such assistance.

Immersion blendersedit

The hand-held immersion blender, stick blender, hand blender or wand 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.

The operation of an immersion blender requires that the user hold down a switch for as long as the blades operate, which can be tiresome for the user.

Handheld blenders are ideal for small and specific tasks but do not have as many uses as a countertop blender.

Mechanical operation

A blender consists of a housing, motor, blades, and food container. A fan-cooled electric motor is secured into the housing by way of vibration dampers, and a small output shaft penetrates the upper housing and meshes with the blade assembly. Usually, a small rubber washer provides a seal around the output shaft to prevent liquid from entering the motor. Most blenders today have multiple speeds. As a typical blender has no gearbox, the multiple speeds are often implemented using a universal motor with multiple stator windings and/or multi-tapped stator windings; in a blender with electromechanical controls, the button (or other electrical switching device or position) for each different speed connects a different stator winding/tap or combination thereof. 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...

Development

North America edit The Polish-American chemist Stephen Poplawski, 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 which had been designed to make Horlicks malted milkshakes at soda fountains. He also introduced the liquefier blender in 1922. In the 1930s, L. Hamilton, Chester Beach and Fred Osius, produced Poplawski's invention under the brand name Hamilton Beach Company. Fred Osius improved the appliance, making another kind of blender. He approached Fred Waring, 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 in the 1940s. Waring Products was sold to Dynamics Corporation of America in 195...
