Mixers refer to tools or appliances used to combine ingredients together. There are a variety of synonyms for mixers, such as blenders, beaters, whiskers, agitators, stirrers, and emulsifiers. Blenders are the most commonly known synonyms for mixers, which use sharp blades to combine ingredients. Beaters are hand-held mixers that are utilized to whisk eggs, cream or batter. Whiskers resemble handheld beaters, but with individual strands that are used to mix and aerate ingredients. In contrast to beaters and whiskers, agitators and stirrers have fewer moving parts that mix ingredients on a low speed, and they are commonly used in laboratories. Lastly, emulsifiers rely on complex mechanisms to combine and evenly distribute ingredients with different compositions.
