0.9 Cu Ft Digital Vacuum Drying Oven

schools and scientific institutions. Heating and drying under vacuum condition shows the following

advantages:

a. Drying temperature can be lowered. (Low pressure and low temperature).

b. Oxidation of some articles after heating can be avoided with no damages done by dust.

c. Slaughter of biological cells caused by heated air can be avoided.

Usage

1. Put the items that need to be dried into the box, close the box door and tighten the door handle, close

the return valve, open the vacuum valve, connect the air duct on the side of the vacuum drying box to

the vacuum pump with a vacuum rubber tube, connect the power to the vacuum pump, and start pumping.

When the vacuum gauge indicates the desired vacuum degree, close the vacuum valve first, and then turn

off the vacuum pump. At this time, the box is in a vacuum state.

2. After connecting the power, turn on the power switch and the indicator light will light up, indicating normal

operation. The instrument will display the temperature of the studio, and then adjust the control instrument

to the set temperature. The studio will start heating, and the green light on the control instrument will light

up, indicating power on and heating. After the instrument remains constant for 60 minutes, the temperature

displayed on the instrument should be basically consistent with the set temperature.

3. Choose different drying times for different items and temperatures. If the drying time is long and the

vacuum degree decreases, it is necessary to pump air again to restore the vacuum degree. The vacuum

pump should be turned on first, and then the vacuum valve should be opened.

4. After the drying is completed, the power should be turned off first, the return air valve should be turned on,

the vacuum inside the box should be released, and the box door should be opened to remove the items（After

contact with the vacuum, the rubber ring is tightly attached to the glass door, making it difficult to open the

box door. It will take some time for it to be easily opened）.

5.In a vacuum state, the control temperature should not be lower than 50 ℃. If it is below 50 ℃, the

value tested by the standard thermometer is different from the inconsistent display values on the instrument

panel are a normal phenomenon. This phenomenon does not affect temperature control and temperature

above 50 ℃.

agricultural scientific research, environmental protection and other research and application fields, for powder

drying, baking and disinfection and sterilization of all kinds of glass containers. It is especially suitable for r

apid and efficient drying of heat-sensitive, easily decomposed, easily oxidized substances and complex

components.

Precautions

1. The vacuum drying oven must be effectively grounded to ensure safety.

2. When the vacuum drying box does not need to be connected for air extraction, the vacuum valve should be

closed first, then the power supply of the vacuum pump should be turned off, and the vacuum pump air

ballast valve should be opened at the same time, otherwise the pump oil will pour back into the box.

3. When removing the processed item, if it is flammable, it must wait for the temperature to cool below the

ignition point before being released into the air to avoid combustion.

4. The vacuum box is not equipped with explosion-proof devices and explosive materials must not be placed

for drying.

5. If conditions permit, a filter should be installed between the vacuum box and the vacuum pump to prevent

humid gases from entering the vacuum pump.

6.There is a small hole on the top of the silicone oil gauge to ensure that the pointer points to 0. If it

is inverted during transportation, there may be slight oil leakage, which is a normal situation. After drying, it

can be used normally.

7.After the work is completed, be sure to take proper protective measures to prevent burns.
