Immersion
Immersion or handheld blenders are long, thin blender appliances that you hold in your hand and submerge in the food or drink you're preparing. The shaft has a long neck with blades at the end, so you can mix and chop food in the cooking container—say, purée soup vegetables right in the pot they simmer in. These products are good for quickly mixing milkshakes or smoothies that do not require a large amount of heavy ingredients to be blended together.
