Bowl capacity
The volume of the food bowl provided in the food processor. Most often the full volume is indicated, not the working volume. It should be noted that you can not use the bowl completely when cooking, the working volume is approximately 70% of the total. Thus, about 4 liters can be used in a 6 liter bowl. And if you go into the recipes and power modes of the food processor (see the instructions), then smaller numbers are acceptable for preparing a particular dish (kneading dough, mixing salad, etc.).
Note that a large capacity affects the dimensions and weight of the unit, and also requires a more powerful engine — which affects energy consumption and price. So when choosing a bowl by capacity, you should not chase the maximum capacity, but take into account the planned volumes of work.
Body material
The main material used for the body of the unit.
—
Plastic. The main advantage of plastic is the relatively low cost. In addition, this material can have almost any colour, including quite bright ones. In terms of strength and reliability, the plastic is inferior to metal, but this difference does not play a special role in normal use, it becomes noticeable only in various emergency situations (during falls, overheating, etc.). Also, plastic bodies are relatively easy to scratch, but this point mainly affects the appearance of the unit and does not affect the functionality. In light of all this, only plastic is the most popular material for the bodies of modern food processors.
—
Metal. Metal bodies are distinguished by their solid appearance and high strength. On the other hand, this material is noticeably more expensive than plastic, and therefore is less common — mainly in middle and high class food processors.
