Different blenders have different functions and features but product testing indicates that many blenders, even less expensive ones, are useful for meeting many consumer needs.[1] Features which consumers consider when purchasing a blender include the following:

  • large visible measurement marks[1]
  • ease of use[1]
  • low noise during usage[1]
  • power usage (typically 300-1000 watts)[1]
  • ease of cleaning[1]
  • option for quick "pulse" blending[1]

Countertop blenders[edit]

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

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.[1]


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 blenders[edit]

The hand-held immersion blender or stick blender has no container of its own, but instead has a mixing head with rotating blades that can be immersed in a container.[1] 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.[1]

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.[1]

Handheld blenders are ideal for small and specific tasks, but do not have as many uses as a countertop blender.[1]


Countertop blenders are designed to mix, purée, and chop food.[1] Their strength is such that the ability to crush ice is an expected feature.[1]

Blenders are used both in home and commercial kitchens for various purposes, including to:

  • Blend ice cream, milk, and sweet sauces to make milkshakes
  • Mix and crush ice in cocktails such as the Zombie, piña colada and frozen margarita
  • Crush ice and other ingredients in non-alcoholic drinks such as frappuccinos and smoothies
  • Emulsify mixtures
  • Make smooth purées of semi-solid ingredients, such as cooked vegetables and meat
  • Reduce small solids such as spices and seeds to powder or nut butters
  • Blend mixtures of powders, granules, and/or liquids thoroughly
  • Help dissolve solids into liquids



North America[edit]

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[2] which had been designed to make Horlicks malted milkshakes at soda fountains. He also introduced the liquefier blender in 1922.[3][4]


Also in 1937, W.G. Barnard, founder of Vitamix, introduced a product called "The Blender,"[5] which was functionally a reinforced blender with a stainless steel jar, instead of the Pyrex glass jar used by Waring.

In 1946 John Oster, owner of the Oster barber equipment company, bought Stevens Electric Co. and designed its own blender, which Oster commercialized under the trademark Osterizer. Oster was bought by Sunbeam Products in 1960.[4] which released various types of blenders, as the Imperial series and still make the traditional Osterizer blender.


A Electric centrifugal juicer

In Europe, the Swiss Traugott Oertli developed a blender based on the technical construction and design style conception of the Waring Blendor,[citation needed] releasing in 1943 the Turmix Standmixer.[6] 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 (de) had promoted the benefits of drinking natural juices made with fruits and vegetables, with recipes using juices to promote its blender and juicer. Now the juicer vs blender argument is an extremely hot topic in the fitness and health conscious community. Some say blenders are healthier, while the others say juicers are more efficient. But both the juicer as well as the blender have their own strengths and weaknesses, and it would be unfair to rate any one of them as being “better” than the other based off one strength. Juicers are better with juices, blenders are better with smoothies. [7]


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. Soon thereafter, Walita acquired the Turmix patents in Brazil and also released the Turmix juicer, calling it the 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 Royal Philips' kitchen appliances developer division specializing in blenders, which are sold under the Philips brand outside Brazil.


Increased versatility[edit]




In 1996 Tom Dickson, founder and CEO of Blendtec, introduced the WildSide blending jar — a unique design that eliminated the need for stir sticks and plungers to make thicker blends. The technology was so effective that Vita-Mix decided to use the design in the company's commercial blending containers. In 2010 the United States court system concluded that Vita-Mix had willfully infringed the patents, ultimately awarding Blendtec $24 million in damages.[9]

Mechanical operation[edit]

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 multitapped 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 material inside the food container. A notable exception from the mid-1960s is the Oster Model 412 Classic VIII (with the single knob) providing the lowest speed (Stir) using the aforementioned winding tap method but furnishing higher speeds (the continuously variable higher speed range is marked Puree to Liquify) by means of a mechanical speed governor that balances the force provided by flyweights against a spring force varied by the control knob when it is switched into the higher speed range. With this arrangement, when not set to the Stir speed, motor speed is constant even with varying load up to the point where power demanded by the load is equal to the motor's power capability at a particular speed. The more modern version of this arrangement is electronic speed control found on some units.

In culture[edit]

In 1949 the company Vitamix advertised their blender in one of the first television infomercials.[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 entire raw eggs and their shells, which the host announced would be enjoyed like Malted milk.[10]
