Food choppers are set up by plugging them in, then placing the bowl component, blade and lid on, in that order. Place ingredients inside the properly-assembled machine, make sure the lid is closed and secure, and then use the machine to chop the ingredients using the blade component.
A food chopper is a simplified food processor, a type of appliance that replaces some of the tasks ordinarily done manually using a knife. A food processor can perform many tasks depending on the attachments available to a specific model, with some models created only for specific processing tasks. Proper assembly for each machine is different, so it is best to get familiar with what attachments and components are available with a given machine.
Most food processors are assembled by placing the main bowl on the appliance and locking it on, and then adding the blade attachment, and finally the lid. Some extra steps are involved with certain food processor attachments. In the case of food choppers, which tend to be smaller and simpler, this is the minimum amount of steps involved for most models.
Walmart sells many different brands of food choppers, but they do not have their own brand. Some of the brands Walmart offers on the company's online store include Procter Silex, Hamilton Beach and Chefman.
