Food processors are similar to blenders in many forms. The primary difference is that food processors use interchangeable blades and disks (attachments) rather than a fixed blade. Also, their bowls are wider and shorter, a more proper shape for the solid or semi-solid foods usually worked in a food processor. Usually, little or no liquid is required in the operation of the food processor, unlike a blender, which requires a certain amount of liquid for the particles to move around the blade.
Food processors normally have multiple functions, depending on the placement and type of attachment or blade. These functions normally include:
Slicing/chopping vegetables
Grinding items such as nuts, seeds (e.g. spices), meat, or dried fruit
Shredding or grating cheese or vegetables
Pureeing
Mixing and kneading doughs
