When To Use Food Processors Or Blenders?

By Arnold Waterborn


Naturally cooks are always seeking to find the best kitchen tools and if they can conserve kitchen space and money at the same time, so much the better. That is why a lot of people might think that a blender and a food processor are interchangeable items, but they were really designed to do different things so that might not be a good idea.

A food processor is defined as "an electric appliance with interchangeable blades within a closed container into which food is inserted for slicing, shredding, mincing, chopping, pureeing, or otherwise processing at high speed." This just means an appliance that is designed to turn larger chunks of food into smaller chunks.

Some of the physical features of a food-pro are a low power motor and a small stocky frame. The motor inside of a food processor usually runs in the area of 450 to 700 watts. This is around the same power as a cheaper blender, but it doesn't compare to the higher quality blenders now used in many kitchens.

Blenders like the Vitamix 1710 can cost as much as $600, but has a 1500 watt motor. The lower the wattage of the blender, the more likely you will need to have a second appliance available for your chopping needs. Some people do find good use in a food processor though.

It seems that if you had a very powerful blender, you would not need another appliance. Just because the motor is weaker, does not mean that it does not perform a good job. A food processor is good at chopping and cutting food into consistent chunks of the same size. In a blender, food is pulverized very quickly. It is hard to keep larger chunks in a blender, especially if you were trying to make something like coleslaw.

In addition, a food processor is meant for dry foods and is better for them, while a blender is really made to blend liquids or to turn soft solids into liquids if you wish. Even a very inexpensive and simple blender will usually do a great job of mixing up your smoothies or your soups better than any other type of equipment.

In order for there to be circulation, there needs to be just a small part of the jar empty. A food processor needs to have only a bit of liquid in it and if that doesn't happen, there may be sloshing of the liquid that makes things very messy. And that mess can be dangerous if it shorts the motor and leaves the important parts of the machine exposed.

But food processors do get around one major pain: cavitation. As explained by blender experts, cavitation often occurs when an air pocket forms around the blades, shoving the contents to the sides of the blender. Reaching the desired consistency is a challenge if the ingredients are too cold, too dry, or too stringy. Also, blending mostly dry ingredients is likely to form a powder, instead of the creamy consistency you would expect from say, nut butters. So to avoid cavitation, a food processor would be the best choice.
