High Quality 600V Industrial Tray Dryer for Spice Medicine Processing

Vacuum debugging can be performed as follows:

A. Turn on the power supply of the empty box, and the power indicator light should be on at this time (6090 and 6210 models should be turned on the thermostat switch respectively). The thermostat will perform power-on self-test, and the PV screen will display the temperature

measured in the working room, while the SV screen will display the temperature set when leaving the factory. The AT and HEAT lights on the temperature controller should be on, indicating that the instrument enters the working state of heating.

B. Modify the setting temperature

1. Press the function key (SET) of the temperature controller; PV screen display SP character, can be used to modify the setting temperature button (6090 and 6210 for 2 and 3 meters should be set and modified respectively, the following similar).

2. After the modification is complete, press the SET key again. The PV screen displays the ST character and sets the timing time.
If the timing function is not used, it is still set to ST=0

3. Press the SET key again to make the PV screen display the studio temperature and the SV screen display the new SET temperature. The instrument AT and HEAT lights on, and the instrument enters the working state of heating again.

C. When the temperature in the working room is close to the set temperature, the HEAT light goes on and off, indicating that the heating enters the PID adjustment stage. It is normal that the temperature measured by the instrument sometimes exceeds the set temperature and

sometimes is lower than the set temperature. When the measured temperature is close to or equal to the set temperature, the studio will enter the constant temperature state after 1~2 hours, and the articles will enter the drying stage.

D. When the required temperature is low, the secondary setting mode can be adopted. For example, the required operating temperature is 70℃. Set 60℃ for the first time, and then set 70℃ for the second time after the isothermal overshooting starts to fall, which can reduce or even eliminate the temperature overshooting phenomenon and enter the constant temperature state as soon as possible.

E. Turn off the power supply when the goods are dry. If the temperature drops rapidly, open the air valve to make the vacuum degree 0, and wait for about 5 minutes before opening the door.

4. If the humidity of the dry material in the working room is high, the generated moisture will affect the performance of the vacuum pump. It is recommended to connect a dryer/filter between the drying oven and the vacuum pump.

5. If nitrogen and other inert gases need to be added in the process of drying goods, it should be indicated in the contract and an intake valve should be added.
