An eggbeater is a handheld device with a crank on the side geared to one or more beaters. The user grips the handle with one hand and operates the crank with the other, creating the rotary action.
Mixers help automate the repetitive tasks of stirring, whisking or beating. When the beaters are replaced by a dough hook, a mixer may also be used to knead.
A mixer may be a handheld mechanism known as an eggbeater, a handheld motorized beater, or a drill mixer. Stand mixers vary in size from small counter top models for home use to large capacity commercial machines. Stand mixers create the mixing action by either rotating the mixing device vertically (planetary mixers), or by rotating the mixing container (spiral mixers).
