A food processor is a small appliance that is used to chop, shred, and dice food. The wattage of a food processor is the amount of power that it uses. A good wattage for a food processor depends on what you will be using it for. If you will be using it to chop vegetables, then a lower wattage will suffice. However, if you plan on using it to make dough or grind meat, then a higher wattage is necessary. The average wattage of a food processor is between 500 and 1000 watts.
