Talk about kitchen black technology that is unexpected but may be realized or has been realized?

With the development of science and technology, the era of single cooking in our kitchen has passed, and it is not difficult to use one machine for multiple purposes. The built-in steaming oven won't take up too much space in the kitchen. Steaming oven is equivalent to microwave oven, oven and steamer. When cooking food, steaming and roasting are carried out at the same time, which can not only retain the nutrition of the food itself, but also create a good taste. In addition, a variety of breads and desserts are available.
