The Blendtec has power. In the high-performance blender from the USA works a robust one-piece blade with blunt safety blades. These smash or pulverize ingredients more than they actually cut them. This sounds brutal - but when preparing green smoothies, for example, it offers the advantage that lettuce, spinach or collard greens are not simply chopped up, but that all the valuable ingredients are extracted by the action of the blades and thus made accessible for digestion. In combination with the high speeds (max. 32,000 revolutions per minute), the heavy blade manages vegetables and fruit of even the hardest variety and even frozen foods: ice cubes or frozen berries, for example. The friction generates heat, so that (raw food) cream soups can also be prepared within a very short time when the appropriate program is selected. A digital touch display with slider and pulse function facilitates operation. 100 speed levels are possible. The large carafe with a volume of 2.7 liters is made of the same plastic as the windows in airplanes and is extremely resilient. With full intention: because a container made of glass would not withstand long in use and burst into a thousand pieces at the high pressure exerted.
