An oven with a capacity of 1 and a general capacity of more than 25L can be called a large oven. The internal space of the large oven is relatively sufficient, the temperature distribution is more uniform, the constant temperature effect in the heating process is better, and the food is heated more evenly. The smaller the internal space of the oven, the more uneven the heating, the lower the internal height, and the food is close to the heating tube, which is easy to paste outside and still raw inside.
2. The capacity of embedded electric oven ranges from 20L to 60L. It is not that the larger the oven capacity, the better. You'd better choose the one that suits you. In the choice of electric oven capacity, if it is only used to bake cookies for a family of three, about 20 liters is enough. If you want to make a roast turkey dinner or barbecue party, try to choose a large-capacity and multifunctional product, the capacity can be more than 35L. The lower the power, the better. The higher the power, the faster the temperature rises, and the less the heat loss, but it will save electricity.
