KITCHEN KING A BLENDER IS THE APPLIANCE YOU CAN'T LIVE WITHOUT IF YOU WANT TO TURN SOLID INGREDIENTS INTO LIQUID DELICIOUSNESS . TEXT AND GRAPHICS BY SANTOSH KUSHWAHA Blenders are versatile appliances that have a variety of uses in the home , busi ness and laboratory . Basically , a blender has a motor at the bottom with a con trol panel that has several different speeds . This motor drives a pitched blade that chops items that are put in the blender . A tapered cylindrical pitcher with a lid attaches to the base . The shape of the pitcher and the pitch of the blades create a kind of tornadic action which circulates the contents and chops them to the desired consistency . The pitcher has a lid that usually has a rubber seal . This seal prevents any food from spraying out . Blenders also have a place in idustry labs for research in areas like microbiology , where researchers use it to extract bacteria from samples . AIR HISTORY OF BLENDERS Food processor 2 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 . HOW IT WORKS 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 ingredi ents 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 . As the strawberry combines with the other ingredients and begins to liquify , the liquid follows the blade The whirling motion and lack of space below the blades forces the 3 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 . 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 . 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 . 1922 The blender is invented by Stephen Poplowski . 1935 Fred Osius improves on Poplawski's idea and creates the Waring Blender . FEEDER CAP : Doubles as a measuring cup , and lets you add foods while blending . RUBBER SEAL : Seals jug and agitator blade assembly . JAR COUPLING BLENDER MECHANICS 1938 The Waring Blendor is an instant success with hotel and restaurant owners . COVER BLENDER JUG : Holds 5 cups ( 1.25 L ) .
