The difference between a double-layer oven and a single-layer oven is:

1. Space. Generally, the space of a single-layer oven is small, and the scope of use has space limitations. The double-layer oven has a relatively large space and a relatively large selectivity.

2. Temperature. Because of the small space, the single-layer oven heats up quickly, so the temperature is generally lower than that of the double-layer oven. On the contrary, the space of a double-layer oven is relatively large, so the maximum temperature limit is higher than that of a single-layer oven.

3. Power. The double-layer oven has a higher temperature and power than a single-layer oven because of the need to radiate the double-layer bakeware.

4. Effect. The double-layer oven is more evenly heated than the single-layer oven because of the large space, so the double-layer oven has a better baking effect than the single-layer oven.
