Description:

Mixing devices are hand-held mixers, hand-held blenders and blenders.

A hand mixer is an electrically driving kitchen device for mixing foods or whipping cream. The alternating magnetic field at the fundamental frequency of 50 Hz resp. 60 Hz is caused by the motor driving the processing tool. Generally, hand mixers consume 200 - 500 W.

A hand blender is an electrically driven kitchen appliance for mincing food. In contrast to an ordinary blender, the knives of a hand-held blender are integrated into the handheld part so that food can be processed in various containers. The alternating magnetic field at the fundamental frequency of 50 Hz resp. 60 Hz is caused by the operation of the motor for the rotation of the knives.

A blender is an electrically driven device for pureeing foods. In contrast to a hand mixer, the knives of a blender are integrated inside a glass or plastic container which is filled with the food to be mixed. The alternating magnetic field at the operation frequency of 50 Hz resp. 60 Hz is caused by the motor which drives the rotating blades.

Frequency ranges:
  • 50–60 Hz
