Steamers and combi ovens are large-capacity ovens that cook large batches of food at once. Steam kettles are large stainless steel pots with a large volume of water and a steam function that can be used for cooking large amounts of food at once. All of these appliances can be used to cook large batches of food at once with little hands-on time.
They are available in various sizes, most of which are made of stainless steel. Some of the most common features found on these appliances include programmable timers, internal lighting, and self-cleaning capabilities. You can easily set the desired temperature on your combi oven. A steam kettle has a wide opening, making filling easier.
