How to do molecular distillation equipment vacuum check?
Excellent vacuum system is essential for efficient operation of molecular distillation equipment
and affects the quality of cbd distillate. So how to do molecular distillation equipment vacuum check? So it is important to ensure that the short path distillation equipment
is in a good vacuum. -
During the vacuum test, when the molecular distillation machine
reaches the final pressure, close the short ball valve and the vacuum pump butterfly valve of the vacuum pump, and if necessary, turn off the vacuum pump.At the beginning, due to the escape of residual gas at the connection of the short path distillation equipment
, the vacuum gauge shows that the pressure rises at a relatively fast speed, and the continuous pressure rise will become a stable linear increase trend, the leakage rate of the equipment is calculated by the slope of the pressure rise curve.The vacuum leak rate of the molecular distillation
device is calculated according to the following formula: -
If the leak rate is higher than the allowable value of the process, please check the following points:
1. Check each joint, flange, and part and tighten one by one.
2. Check each drain valve and exhaust valve.
3. Check each stop valve.

If the cause of the leak cannot be found, please check the short path distillation equipment
with the leak test device, or contact [email protected]
to get technical support.
