The vacuum drying oven is a box type equipment used for experiments in a vacuum environment. The vacuum drying box is suitable for vacuum storage of electronic and electrical products such as semiconductors, electronics, electrical components, wafers, chemical raw materials, metallurgical powders, and the like.

How to use a vacuum drying oven? A constant instrument / Shanghai Yiheng to answer your questions, the steps are as follows:

1. Place the items to be dried in a vacuum drying oven, close the door, close the bleed valve, and open the vacuum valve.

2. Connect the air pipe behind the vacuum drying box to the vacuum pump with a vacuum rubber tube, and turn on the vacuum pump to start pumping. When the vacuum gauge indicates 0.1Mpa , close the vacuum valve and turn off the vacuum pump power switch.

3. Turn the vacuum oven power switch to the “on” position, select the desired set temperature, and the temperature inside the box will start to rise. When the temperature inside the box is close to the set temperature, the heating indicator will be turned on and off repeatedly. Generally , the shelf level enters a constant temperature state within 120 minutes.

4. When the required working temperature is low, the secondary setting mode can be adopted. If the required working temperature is 60 degrees, the first time can be set to 50 degrees first , and the temperature overshoot starts to fall back, and then the second time is set. Set 60 degrees, this can reduce or even eliminate the temperature overshoot phenomenon, enter the constant temperature as soon as possible.

5. According to the different moisture levels of different items, choose different drying time. If the drying time is too long, the vacuum degree will drop. If you need to pump again to restore the vacuum, you should first turn on the vacuum pump motor switch and then open the vacuum valve.

6. After drying, turn off the power, turn the bleed valve, release the vacuum inside the box, and then open the box door to take out the items.

7. When the vacuum box does not need continuous pumping, the vacuum valve should be closed first, then the vacuum pump motor power should be turned off, otherwise the vacuum pump oil should be poured into the box.
