The capacity of the oven should be at least 30 liters, the power should be at least 1600 watts, and the heating should be uniform. Only one broiler can be roasted in 25 liters. It's not easy to turn if it's bigger. /kloc-Don't buy anything less than 0/0 liter. There is only enough space to bake a few cookies, and the use is very limited.
In addition, the oven with small capacity on the market basically has no temperature control function of the upper and lower tubes, which means that the two tubes heat at the same time when working, and there is no intermediate layer. The direct result is that either the upper one is too hot or the lower one is too hot to achieve uniform heating.
Extended data:
The use of the oven is introduced as follows:
The problem of uneven heat transfer in a small oven can be effectively solved by selecting the one with hot air circulation function and heating the air in a closed oven. The realization method is to install a hot air circulation system in the middle or edge of the oven to speed up heat exchange and conduction. For barbecue, crispy pizza has the best effect, and this function is essential to achieve the effect of tender outside and tender inside.
Be sure to choose the upper and lower independent temperature control function. It is better to have a larger temperature control range, which can meet the cooking needs of different foods. The temperature of the upper and lower tubes is different, and the cooked taste is different. Many foods need to be colored or coked in the final stage, so they need to be heated separately through the upper tube. The temperature control is preferably freely adjustable between 0-250 degrees.
