In the world of baking, the oven is a magical castle where cakes, breads, cookies and other delectable desserts are born. But have you ever tried to follow a recipe, set the temperature and time, and come up short. The cake was blackened on the outside but not quite done on the inside. Some cookies are charred, others are doughy. The most likely culprit for these baking failures is poor oven temperature control. Today, let us walk into the scientific world of oven temperature control accuracy testing, unveil the mystery behind this.

1.No-load temperature test

No-load temperature test is one of the commonly used temperature control precision detection methods. Before testing, give the oven a"Preheat cleanse"-turn the oven to maximum temperature and bake for 20-30 minutes without heat. This not only removes impurities and odors that remain in the oven, but also allows the components to work at their best. Next, place a professional oven thermometer in the center of the oven, set the oven to a target temperature, such as the usual 180 °C, and record the actual temperature every few minutes. In this process, you will find that the oven temperature is not fixed, but there will be a certain fluctuation. For qualified ovens, the temperature fluctuation should be within ± 5 °C of the set temperature. If the fluctuation exceeds this range, it shows that the oven temperature control system may have problems, need further investigation and adjustment.

2.Load temperature test

The load temperature test is an in-depth physical examination of the oven, simulating the rigors of a real baking scenario. We carefully selected and common baking ingredients similar to the specific heat of the material, such as room temperature water or special silicone simulation block, placed on the baking tray into the oven. Load into the box, the oven temperature trend and no-load is very different, the food endothermic temperature drop in the box. At this point, keep an eye on the thermometer and record exactly how long it takes to stabilize from the set temperature and the exact temperature after it has stabilized. The load temperature curve was drawn by testing different loads for many times, so as to understand the temperature temperament of the oven under different baking situations and provide a strong basis for the precise temperature regulation and timing of the actual baking.

3.Heat distribution uniformity test

The heat distribution uniformity test creates an accurate temperature panorama of the oven. The inside of the oven is carefully divided into several zones, where individual temperature sensors are placed. These sensors act as dedicated temperature mini-guards, capturing temperature fluctuations in real time in all directions and from all corners. When the oven temperature stabilizes to the set value, record the sensor data of each area. The results show that the temperature in the oven is uneven, like a furnace near the heating tube, and a cool room in the corner away from the heating tube. Professional Bakers Tailor the baking plan for each oven, shortening or lowering the baking time in high-temperature areas, and moving ingredients or extending the baking time in low-temperature areas to perfect the baking.

4.Temperature Recovery Ability Test

During a baking operation, opening the oven door to check the status of the ingredients or turning them over is unavoidable, which can cause the temperature in the oven to plummet, so testing temperature recovery is critical. During the test, the oven is preheated to a set temperature and held steady, then the oven door is quickly opened for about 30 seconds and closed, accurately recording the time between the door opening and the temperature returning to the set value. Excellent performance of the oven can quickly rewarming, greatly reducing the interference of temperature fluctuations on baked goods. If the oven is not good at rewarming, you need to be more careful when operating. Open the door to check the Split Second. You can also raise the oven temperature a few degrees in advance as a buffer to maintain a relatively stable temperature in the oven and ensure baking results.

Conclusion

By scientifically testing the accuracy of oven temperature control, we can more accurately control the oven temperature, making every baking a wonderful experience. Whether it's sweet cakes, crunchy cookies, or fluffy bread, it's the precise temperature that brings out the best in you.
