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 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. High-powered blenders are capable of milling grains and crushing ice without such assistance.
The blades create a whirlpool effect which moves solids from top to bottom, ensuring even contact with the blade. In these blenders, the liquid helps move the solids around the jar, bringing them in contact with the blades. Low-powered blenders require the addition of some liquid to operate correctly. Most modern blenders offer a number of possible speeds. The container rests upon a base that contains a motor for turning the blade assembly and has controls on its surface. The blending container is generally shaped in a way that encourages material to circulate through the blades, rather than simply spinning around. 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. Ĭountertop blenders typically offer 2–16 speed settings, but having more choices in speed settings is not an indication of increased utility for all users.
Stainless steel is preferred for its looks, but limits visibility of the food as it is blended. Plastic is prone to scratching and absorbing the smell of blended food. Glass blenders are heavier and more stable. power usage (typically 300–1000 watts) Ĭountertop blenders use a 1–2 liters (4–8 cups) blending container made of glass, plastic, stainless steel.Features which consumers consider when purchasing a blender include the following: The newer immersion blender configuration has a motor on top connected by a shaft to a rotating blade at the bottom, which can be used with any container.ĭifferent 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. Some powerful models can also crush ice and other frozen foods. A stationary blender consists of a blender container with a rotating metal blade at the bottom, powered by an electric motor that is in the base. A blender (sometimes called a mixer or liquidiser in British English) is a kitchen and laboratory appliance used to mix, crush, purée or emulsify food and other substances.
