How a home sandwich maker works?

Home sandwich makers are usually relatively simple and their working principle is relatively basic:

Preheating: First, the user plugs the sandwich maker into a power source and turns it on, allowing it to preheat to the appropriate temperature. Usually, this process only takes a few minutes.

Prepare ingredients: While the sandwich machine is preheating, users can prepare ingredients such as bread, ham, cheese, vegetables, etc. These ingredients usually need to be prepared in advance and placed within easy access of the sandwich maker.

Assemble the sandwich: Users place the bread in the sandwich maker's construction area and then place other ingredients, such as ham, cheese and vegetables, in order according to personal taste. Typically, sandwich makers have special tongs or baking sheets for holding and assembling ingredients.

Heating: Once the sandwich is assembled, the user turns the sandwich maker off or adjusts it to the appropriate temperature and time settings to begin heating the sandwich. Heating time usually depends on the user's taste preference and the type and thickness of the ingredients.

Done: When the sandwich has finished heating, the user can open the sandwich maker and take out the hot sandwich, ready to enjoy.
