1)Put your samples into the vacuum drying chamber, close high temperature vacuum oven door, then close the air release valve, open the vacuum valve, turn on the vacuum pump and start pumping, when the vacuum degree in the working chamber reaches -0.1m Pa, close the vacuum valve, then turn off the vacuum pump power
2) Turn the high temperature vacuum oven power switch to the “on” position, select your needed set temperature, and the temperature inside the working chamber will start to rise. When working chamber 's temperature close to the set temperature, the heating light flash, enter constant temperature state, the oven is working properly.
3) When the required operating temperature is low, a secondary setting method can be used, such as a required temperature of 60 ° C, the first time can be set to 50 ° C, once the temperature overshoot starts to fall back, and the second time can be set to 60 ° C.
This can reduce or even eliminate the temperature overshoot phenomenon, and enter the constant temperature state quickly
4) According to the moisture degree of different material, choose different drying time, such as longer drying time, vacuum degree begin to fall, need to open vacuum pump power again to restore vacuum, then open vacuum valve
5) After drying process finished, should turn off high temperature vacuum oven power supply first, open air release valve, release the vacuum sate in the working chamber, then open the high temperature vacuum oven door to take out the finished dried products
Advantages of vacuum dry technology: ·
Vacuum environment greatly lowered the liquid’s boiling point which needs to be driven away, therefore the vacuum dry method can be applied into heat sensitivity material. ·For the samples which can't be dried easily, such as powder or other pellet form sample, using vacuum dry method may effectively reduce drying time. ·Various complex structures of machinery ministry or other porous sample process use vacuum dry method after washing will not leave any residue; ·Safety guarantee: whether under vacuum or inertia condition, the possibility of oxide explodes when is heated will completely be eliminated. ·Compared with the normal drying method depended on air circulation, powder samples will not be blown or moved away by air
