Have you had the chance to use a food processor?
An Electric appliance developed in the late 20th century, used for a variety of food-preparation functions including kneading, chopping, blending, and pulverizing. The food processor was invented by Pierre Verdon, whose Le Magi-Mix, a compact household version of his own earlier restaurant-scaled Robot-Coupe, was first exhibited in Paris in 1971. Carl Sontheimer, an American engineer and inventor, refined Verdon’s machines to produce the Cuisinart. The widespread success of the Cuisinart following its exhibition in Chicago in 1973 led a number of other manufacturers to design competing models, and hundreds of thousands of food processors were sold in the late 1970s.
A food processor is a kitchen appliance used to facilitate repetitive tasks in the preparation of food. Today, the term almost always refers to an electric-motor-driven appliance, although there are some manual devices also referred to as "food processors".
Food processors are similar to blenders in many ways. The primary difference is that food processors use interchangeable blades and disks (attachments) instead of a fixed blade. Also, their bowls are wider and shorter, a more appropriate 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 some amount of liquid to move the particles around the blade.
Food processors normally have multiple functions, depending on the placement and type of attachment or blade. These functions normally consist of:
- Slicing/chopping vegetables
- Grinding items such as nuts, seeds (e.g. spices), meat, or dried fruit
- Shredding or grating cheese or vegetables
- Mixing and kneading dough
The base of the unit houses a motor which turns a vertical shaft. A bowl, usually made of transparent plastic, fits around the shaft. Cutting blades can be attached to the shaft; these fit so as to operate near the bottom of the bowl. Shredding or slicing disks can be attached instead; these spin near the top of the bowl. A lid with a "feed tube" is then fitted onto the bowl.
The feed tube allows ingredients to be added while chopping, grinding or pureeing. It also serves as a chute through which items are introduced to shredding or slicing disks. A "pusher" is provided, sized to slide through the feed tube, protecting fingers.
Almost all modern food processors have safety devices which prevent the motor from operating if the bowl isn't properly affixed to the base or if the lid is not properly affixed to the bowl.
