Blenders also have a place in industry labs for research in areas like microbiology, where researchers use it to extract bacteria from samples
The newer immersion blender configuration has a motor on top connected by a shaft to a blade at the bottom, which can be used with any container.
History of blenders
1. Let's see how it works. Suppose you drop a strawberry in the blender. You push a button to start the blender, and the motor begins to turn the blades. The circular whirring motion creates a vortex or a spiral movement in the fluid. In the blender, the fluid includes both liquid ingredients and air. The vortex causes a vacuum at the centre of the jar, which pulls the strawberry toward the middle, much as a tornado does.
2. As the strawberry combines with the other ingredients and begins to liquify, the liquid follows the blade in a whirling motion around the container, forming a well near its centre. The well in the centre of a blender's vortex is shallow, so it displaces the contents as they're drawn toward the axis at the centre of the blade.
3. The whirling motion and lack of space below the blades forces the liquified strawberry up and on the sides. This circular pattern continues, whipping air into the contents, which helps mix the ingredients more quickly, until you stop the blender. The final result is a frothy strawberry smoothie with a homogenised blend of ingredients and a consistent texture.
BLENDER VS FOOD PROCESSOR
Food processors are appliances used for solid food, and blenders are better for drinks. Most food processors operate at a single speed, which is slower than a blender, but they have a pulse function that gives you greater control over chopping, kneading and cutting. Food processors aren't suited for crushing ice or making frozen drinks, and blenders are still best for pureeing soups.
