In a cosy kitchen, the oven is a great companion for many home-baked treats. However, it can be frustrating to turn on the oven in anticipation and find that the food isn't cooked to the desired degree. In fact, the oven is not cooked by accident, behind the hidden many scientific factors. Below, let us together in-depth exploration, revealing the truth of the oven cooked.

(1)、Temperature

1. setting the temperature too low

①. Reason

The temperature setting of the oven is the primary factor affecting the baking effect of food. Set the temperature too low, the chemical reactions and physical changes inside the food can not be fully carried out, it is difficult to roast nature.

②. Tthe method of screening

In order to accurately detect the temperature of the oven, you need to prepare a professional oven thermometer, firmly placed in the middle of the oven. Set the required temperature, to be stable operation of the oven, carefully check the thermometer shows the actual temperature. Once the actual temperature and set temperature deviation exceeds ± 10 °C, be sure to timely calibration or contact professional maintenance.

2. uneven temperature

①. Reason

There is often a temperature difference inside the oven, the area near the heating tube is too hot, and the corner or upper layer may not be warm enough. This unevenness can cause parts of the food to overcook or undercook.

②. Screening methods

A plurality of thermometers are placed at different positions in the oven, and the temperature is measured at the same time and the temperature difference is compared. Then check whether the heating tube damage, aging, and oven seal is tight, there is no heat leakage.

3. lack of warm-up

①. Reason

Preheat is an important step before baking food in the oven. Without sufficient preheating, the internal temperature of the oven can not reach the set value quickly. After the food is put in, baking for a long time at a low temperature environment will not only prolong the baking time, but also lead to excessive drying of the food surface, but the inside is still not ripe.

②. Screening methods

First use the thermometer to measure the actual temperature inside the oven, compared to the set temperature. If the actual temperature is much lower than the set value, indicating inadequate preheating. Also observe the preheat time, if a long time does not reach the set temperature, or preheat oven indicator light frequent flashing, also indicates that preheat problems.

(2)、Food arrangement

1. it's not in the right place

①. Reason

The position of the food directly affects the heating effect. High temperatures near the heating tube may cause the surface to burn, while areas away from the tube or in the corner may be underheated.

②. Screening methods

Observe whether the food is too close to the heating tube to cause excessive heat or too far from the tube to cause insufficient heat. Next, observe if the arrangement is too dense to allow hot air to circulate. Finally, check if the food is not placed in the middle of the oven, resulting in uneven heating and undercooked.

2. not using baking sheets or tin foil

①. Reason

The baking tray has remarkable function, which can undertake the dripping grease and juice during baking, keep the interior of the oven clean, and help the food to be heated evenly. Tin foil can reflect heat, avoid the surface of food too quickly burned, lock in moisture, let food fresh and juicy. If you do not use the two, food directly in contact with oven components, easy to cause coke inside.

②. Screening methods

Observe whether the food directly placed on the grill, fat, liquid dripping to the bottom of the oven affect the heat, and then compared with the use of baking tray or tin foil wrapped, whether the food is more evenly heated, can bake normally.

(3)、Oven performance problems

1. aging or failure of heating tubes

①. Reason

The heating tube is the core component of the oven. If the heating tube is aging or malfunctioning, it will reduce the heating efficiency and can not provide enough heat to bake food. For example, the heating tube surface oxidation, damage or uneven light and so on, may be the performance of aging.

②. Screening methods

Check the appearance of the heating tube regularly for obvious signs of damage or aging. When working in the oven, pay attention to observe the light of the heating tube. If some areas are not bright or dim, it shows that the part of the heating tube may have problems and need to be replaced in time.

2. poor circulation of hot air

①. Reason

The hot air circulation system can make the heat in the oven evenly distributed and improve the baking efficiency. If the hot air circulation is not smooth, like the air in the room is not circulating, will lead to local temperature is too high or too low, affect the baking effect of food.

②. Screening methods

Check whether the hot air fan of the oven is working properly and whether there is any foreign matter blocking the vent. Feel the flow of hot air in the oven by hand. If the hot air is weak or uneven, there may be a problem with the hot air circulation system, and the vent needs to be cleaned or the fan repaired.

Conclusion

As long as we master the scientific method of investigation and conduct a comprehensive analysis from the aspects of temperature, food and oven performance, we can find the root of the problem and solve it. Let us use the wisdom of science, unlock the oven baking code, so that every dish can be perfect in the oven bloom.
