2. The oven capacity should be at least 20L (generally 25L) if the whole chicken is roasted.
3. The most popular novice on the Internet is Chang Di 25B (I'm not advertising), mainly because it's cheap, only two or three hundred, and the quality is ok.
4, the first thing to pay attention to when buying an oven is capacity! Common ovens on the market are usually very small ovens, and laymen generally don't look at the capacity of the oven when they buy it. Generally, those small ones can only take a piece of bread and a few chicken wings.
The oven should have a timing key, a temperature control key, and an up-and-down tube adjustment key, which is the most basic, and nothing else needs special attention. Oh, by the way, the oven temperature is generally between 100-250 degrees. It's best to choose a lower temperature, such as 40-250 degrees, and you can mix noodles at a low temperature.
If you plan to roast the whole chicken, the oven should at least have automatic rotation function, and it is best to have hot air circulation. hope this helps
