What is a blender?

A blender is a common household appliance used in kitchens to puree, mix, and otherwise liquefy and break down foods in order to make them easier to digest or to meet the demands of a recipe.

How does it work?

The process is very simple. Older style (but still very commonly used) blenders consist of a holding compartment, usually made of plastic, in which the food that is to be blended is placed, and a rotating blade at the base of this holding compartment. This rotating blade is powered by a motor that runs on electricity, and is cooled by a fan. Blenders usually have several speed settings, which work by manipulating the multiple stator windings that are a part of the motors design. This basic principle is applicable to all types of blenders.

When was it invented?

The history of the blender can be traced back to early 20th century USA, to its invention at the hands of Stephen Poplawski, a Polish immigrant, owner of a well known electronics company. He had invented “drink mixers” that were to be used in the making of soda fountain drinks and beverages that required the mixing of water or milk and an instant powder such as Horlicks. The “liquefier” or blender was a modification of this design. Over the years, several different businessmen have offered several different variations of Poplawski’s original design to the market, including the redesigned “Waring Blendor”, which had a stainless steel body and marked the first time the word blender (or at least a variant of it) was used to describe the product, and Vitamix’s “The Blender”, which first marketed the spelling that would become the standard of this product.

What types of blenders are there?

There are several different kinds of blenders available for you to purchase. There are two distinct types of blenders available: countertop blenders and immersion blenders. The main difference between these two blenders is the presence of a holding compartment for the food, as both types of blenders operate using an electric motor powered blade. Countertop blenders usually possess a holding compartment made of plastic, glass or steel. Glass is recommended for being sturdy but poses the danger of breaking, plastic is more durable but often gets scratched and imbibes most of the smell of the foods that are blended, and steel case blenders provide durability and are easy to clean but one cannot see the food as it is being blended as is the case with the previous two types. Immersive blenders consist of a motor and a blade and can be held in the hand whilst being used. They are placed into a bowl of food that is to be pureed and turned on. However, such blenders are not suitable for large scale blending, and would not be able to handle the same size portions as countertop blenders. They also require the user to keep constant pressure on the “on” button to keep it running, which is often tiresome for users.
