How use rotary evaporator in cbd oil extraction process?
Rotary evaporator is a fixture in many research, not noly as it's a common & economical tool for solvent
removal, but also as it's an ideal instrument necessary for the concentration, drying and recycling.
to guarantee the process must allows the solvent to be removed in a controller manner under vacuum. This
is why rotary evaporator is an idea solvent removing equipment during cbd oil extraction process.
Rotary evaporator whole set should include rotavapor, vacuum pump, vacuum controller and chiller.
It's better to fill your cbd extracts sample in evaporation flask to 50% volume, power on vacuum pump and
vacuum controller, the the pressure is reduced in rotary evaporator, the boiling point of the solvent (enthanol)
is lowered, we could set and control an approprite vacuum to evaporation system lowers the boiling piont,
so as to miniminze thermal decomposition of cbd extracts.
The water bath / oil bath of rotary evaporator could be started heating to 30-40℃, power on the chiller
circulating bath, to control the condenser temperature, which could set to -10℃ to 0 ℃. Please wait the
water bath and condenser temperature have reached your set points, the evaporation flask of rotary
evaporator can start rotating from 150-200rpm. You will find a thin film on the upper surface of glass flask,
which could increase the solution area and enhance the solvent evaporation rate.
During this process, suitable vacuum system is very important. When use rotary evaporator in cbd oil
extraction process, ethanol is the common solvent in cbd extracts, in order to achieve a better target, we
and for rota evaporator, it's very easily scalable, 1L, 3L, 5L, 10L, 20L, 50L, 100L Lab - Pilot - Industry wide
capacity range, such as 50L rotary evaporator, you could choose 5L, 10L, 20L, 30L evaporation flask, this
flexibility makes it very adaptable when processing cannabis.
