Electric hot air drying oven is divided into desktop and vertical types according to its structure, with two temperature control types: electric hot constant temperature and high temperature. This machine is widely used in industries such as medicine, chemical, electronics, and food, for processes such as material drying, vessel sterilization, and component aging. It is strictly prohibited to handle flammable, explosive, and volatile materials.
The usage method of the electric blast drying oven is as follows:
1. Sample placement
Place the items that need to be dried into the drying oven, leaving a certain amount of space around the top and bottom to maintain smooth airflow in the workspace, and then close the oven door.
2. Wind door adjustment
According to the moisture condition of the dry item, turn the air door adjustment knob to the appropriate position, usually to the "z" position; If it is relatively humid Adjust the adjustment knob to the "three" position (note: the adjustment range of the air door is about 60 'angle).
3. Power on
Turn on the power and fan switch. At this time, the power indicator light is on and the motor is running After the temperature controller displays the 'self check' process, the PV screen should display the measured temperature in the working room The SV screen should display the set temperature for drying during use, at which point the drying oven will enter the working state.
4. Set the required temperature
5. Timed setting
If timing is used, when the PV screen displays "5T", the SV screen displays "0"; use the plus key to set the desired interval (minute); after setting, press the SET key once to put the drying oven into working mode.
6. Temperature control inspection
Start up or use for a period of time or when the season changes It is necessary to review the error between the measured temperature in the workspace and the actual temperature, that is, the temperature control accuracy.
7. Shut down
After drying, if it is necessary to replace the dried items, turn off the fan switch before replacing the opening door to prevent the dried items from being blown off.
