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.
Number of speeds
The number of fixed speeds of rotation of the attachments provided in the design of the food processor. The more of them, the more accurately you can choose the required speed for each specific mode of operation. It is worth noting that some devices do not have fixed speeds — the control is carried out smoothly (see Stepless speed controller)
Smooth speed control
A control that allows you to smoothly change the speed of rotation of the food processor engine — for more precise adjustment of speed and setting the optimal mode for different products. With stepwise speed control, a situation may arise when a higher speed value is already too high, and a lower speed is not yet enough.
Smooth control avoids such situations.
Timer
The timer allows you to set the time during which the device will perform a particular function; after a specified period of time is over, the device will automatically turn off.
The food processor with a timer removes the need to monitor the operating time of the appliance and turn it off manually.
Kitchen scales
Availability in the food processor of the
built-in kitchen scales. Usually, the weight sensor is built into the platform on which the bowl is installed; this allows you to determine the weight of the loaded products directly in the cooking process. Of course, other containers can be placed on such scales, not only the "native" bowl of the food processor.
