The embedded oven can have no lower heating tube without independent temperature control. There is hot air circulation on the right side of the oven to make biscuits, but it is more appropriate to use an air oven. Straight pipes are more uniform than bent pipes, and not all embedded ovens can bake double layers. The bigger the oven, the more even it is, and the higher the success rate is.

The other is the embedded oven, which is the upgrade and ultimate version of the small oven. Because of its large power, fast baking speed, good sealing (generally rubber gasket sealing), good heat insulation (three layers of tempered glass insulation), and accurate temperature control, it is loved by more and more people.
