Shaker volume
The working volume of the shaker supplied with the device.
For more information about such containers, see "Shaker (travel bowl)". And on the one hand, the actual capacity of the shaker directly depends on the volume, on the other hand, its dimensions, as well as the requirements for engine power. However, in most models, this indicator ranges from 300 to 700 mL, less often up to 1 liter — these values are considered optimal, taking into account the specifics of the use of shakers.
Shaker (travel bowl)
The number of travel shaker bowls supplied with the appliance.
These bowls are supplied exclusively with blenders of different types (see "Type of device"). A shaker is a capacity, most often in the form of a tall glass, which can be removed from the device, tightly closed and carried with you without fear of pouring the contents. In such capacities, two lids are usually used: a working lid with chopping knives (a bowl with such a lid is placed on the blender with the bottom up), and a “travel” lid, which can be equipped with a valve for easy drinking. Shakers are very popular among smoothie lovers: they allow you to prepare your favorite drink and take it with you without fiddling with pouring from a bowl to another capacity.
