The main reason: From the working principle of the oven, food can be cooked, mostly because of the heat energy circulating in the air inside the oven, and the heating tube of the oven can only be said to be a heat source. Although the part near the heating tube will be baked yellow, the maturity of food ultimately depends on the temperature of the whole space. Therefore, when baking cakes, as long as the height is appropriate, even if the upper and lower temperatures are the same (that is, using a unified temperature-controlled oven), the most. Moreover, the food is at a distance from the lamp below on the grill, so the yellowing degree below is completely negligible.
Therefore, the author thinks that the choice of these two types of ovens is determined by the household usage rate and baking quantity, rather than what kind of food to cook. In addition, it is the height of the oven that determines whether it is suitable for baking.
The height of space determines the quality of baking. Although we mentioned that the maturity of food mainly depends on the thermal energy of space air, in any case, the heat source starts from the heating pipe. If the space height of the oven is not enough and the food is too close to the heating tube, the surface will definitely be burnt. (Even so, it doesn't matter if the upper and lower temperature controls are independent. ) Even if the temperature is controlled independently, the bottom is not sticky, the space height is not enough, and it is too close to the top, the batter still needs to be served.
If you want to make a bigger cake embryo or toast at home, this more advanced pasta, the height of the oven grill and lamp is too low, it is definitely impossible to make it. Choose at least one oven near the commercial space. And this short oven is only suitable for baking egg tarts, biscuits, baked sweet potatoes and the like.
The difference between ovens at different prices The price of ovens on the market is very uneven, generally from several hundred yuan to several thousand yuan, or even tens of thousands of yuan, which makes many people very confused when choosing. Below we will subdivide ovens with different price points. 、
1. 100 yuan oven belongs to mini oven, with extremely small internal space and uneven heating, which is not suitable for baking, but it can still bake an egg tart, biscuits or buns.
2.300-500 ovens commonly used in families have suitable space and are heated more evenly than mini ovens. They can be used for home barbecues and most baking, such as cake embryos, hamburger buns and big biscuits. But baking toast and whole chicken is still too hard because of lack of motivation.
3. 1000 to 3,000 ovens, if you choose thousands of ovens, it is recommended to choose more than 2,000 ovens, because the difference between 1000 and several hundred dollars cannot be guaranteed. If conditions permit, two or three thousand ovens have a wider range of applications, better quality and longer service life, and only reliable brands have this price. Mainly, this oven can basically meet the requirements of baking all baked goods sold outside.
Conclusion: Whether the oven can be controlled independently up and down is mostly due to the extended competition of some brands. When struggling with this, it is better to look at the brand of the oven and the quality of the heating pipe. In addition to different temperature control, with the development of technology, some ovens have added steaming function, which is more practical.
