Usage guide

1, general drying oven. Are used to heat the wall of the vacuum chamber, and then by the wall to the workpiece for radiation heating. In this way, the temperature sensor of the temperature control instrument can be arranged in the outer wall of the vacuum chamber. Generally speaking, 200 ℃ working conditions, the temperature reading of the instrument and the glass rod thermometer readings within 30 ℃ difference between the two is normal. If the temperature sensor of the temperature control instrument is arranged in the vacuum chamber, the temperature value of the glass rod thermometer and the difference between the temperature reading of the instrument can be appropriately narrowed, but it is not possible to eliminate the sealing reliability of the vacuum chamber to increase the reliability of a possible unreliable link.

2, electric drying oven. Are equipped with temperature uniformity parameters: natural convection drying box for the upper limit of the working temperature multiplied by 3%, forced convection drying box for the upper limit of the working temperature multiplied by 2.5%. Vacuum drying oven relying on gas molecules to make the studio temperature to achieve uniformity of the possibility is almost gone. Therefore, from the concept we can no longer put the usual electric heating (blast) drying oven temperature uniformity definition to the vacuum drying oven up. It is also meaningless to set this index under vacuum. The amount of heat radiation is inversely proportional to the square of the distance.

Safety issues that should be noted when using the oven

1. The first time you use the electric oven should pay attention to cleaning. First wipe the oven inside and outside with a clean damp cloth to remove some dust. Then you can empty the oven using high temperature baking for a while, sometimes there may be white smoke, which is a normal phenomenon. After baking, pay attention to ventilation and cooling.

2. After cleaning, you can use the electric oven normally. Before baking any food, it is necessary to preheat the oven to the specified temperature in order to meet the baking time specified in the recipe. It takes about 10 minutes to preheat the oven. If the oven is preheated and left empty for too long, it may affect the life of the oven.

3. Be careful when heating the oven to avoid burns. In addition to the internal heat, the shell and the glass door are also very hot, so be careful when opening or closing the oven door to avoid being burned by the glass door. Always use a handle when placing a baking sheet in or removing it from the oven, and never touch the baking sheet or baked goods directly with your hands. Never allow your hands to touch the heater or other parts of the oven cavity to avoid burns.

4. When the oven is in use, the temperature should be adjusted first. When the oven is in use, the temperature should be adjusted first upper and lower fire, upper and lower fire adjusted, and then twist the time knob clockwise.

5. After each use until it cools down should be cleaned. It should be noted that, when cleaning the box door, furnace chamber shell should be wiped with a dry cloth, do not use water to clean. In case of more difficult to remove the dirt can be gently wiped off with detergent. Other accessories of the electric oven such as baking pan, grill net can be washed with water.

6. The oven must be placed in a ventilated place. Don't lean too much against the wall to facilitate heat dissipation. And it's best not to put the oven near a water source, because the overall temperature of the oven is high when it's working, and if it touches water it will cause a temperature difference.

7. When the oven is working, don't stay in front of the oven for a long time. Don't stay in front of the oven for a long time. If the glass door of the oven is found to have cracks or the like, please stop using it immediately.
