Convection oven – what is it, the principle of operation, an overview of models with a description of functions, photos and cost

The content of the article



The goal of developing many cookware and appliances is to speed up the preparation of high-quality, tasty food. A convection oven is a household appliance used for the heat treatment of products. The principle of its operation is the uniform circulation of hot dry air or steam. The power of the fans located inside the chamber can be adjusted along with the temperature and the degree of humidification. The name of the furnace was given in honor of the physical phenomenon of convection – heat exchange provided by particle flows with different temperatures.

Application area

The most widespread professional equipment for heating, based on the effect of convection, has received in cooking. There are also industrial models whose length, width and height make it possible to accommodate objects of different sizes and dimensions. The bulk of convection ovens is created with the aim of preparing hot dishes in the kitchen, baking. An additional function of the electric grill is provided by powerful heaters (tubular electric heaters) located on the upper and lower inner panels of the heating chamber.

Due to the adjustable steam humidification, the oven also acquires the function of a large double boiler. The wide scope of the convection oven in combination with the impressive capacity of the inner chamber has served this type of equipment a good service: combi steamers from popular manufacturers can be found in the kitchen of any large restaurant or dining room.

Principle of operation

The principle of operation of the air grill is based on the effect of convection: this is the process of heat exchange between directed gas flows (in this case, air). It is achieved by a powerful fan on the rear wall of the heating chamber and 3-4 heating elements above and below. Most of these devices have a humidity control function, which helps to cook steamed dishes, simulating the process of stewing, boiling, water bath. If the corresponding switch is set to “zero”, the standard grill mode will turn on, and very dry hot air will remain in the oven, perfect for baking.
