2. The better ovens that can be seen in the market are brands such as ACA, with good quality and accurate temperature control, and some have new functions such as fermented yogurt. The disadvantage is that it is more expensive, about 20 liters will cost 600~800.
3. Chang Di oven is the most commonly used oven for baking enthusiasts, and the most commonly used oven is 25B, which is about the size of a microwave oven. This brand is exported, which is generally not sold in domestic supermarkets, but many sellers in Taobao can choose local sellers with warranty. Generally, the price of 25B Chang Di oven is within 300 yuan, including the rack for roast chicken (which can really roast the whole chicken), the grill net, and some accessories such as slag tray. It is said that the new Chang Di oven can also make yogurt now. The advantages of this brand are easy to use and high cost performance. I have used it for more than two years, and it is still very good. The disadvantage is that the temperature control is not accurate. You should observe the temperature several times before and master the experience.
To sum up, Chang Di 25B oven is recommended. You can search on the Internet. Many famous bakers use this type of oven.
