Operation:


Extraction:

The extraction vessels are packed and extracted via an alcohol flushing system driven by vacuum. Alcohol is pulled from the alcohol reservoir and flushed through the herb. The herb can be soaked for hours or rinsed for 10-15 minutes. Once the flush/soak is complete, the alcohol extraction is now ready for distillation/recovery.

Recovery:

With the turn of a few valves, the tincture is injected and sprayed inside a heated column. The alcohol forms a thin layer under vacuum where evaporation occurs instantly. The evaporated alcohol is simultaneously re-condensed into the recovery vessel. The speed of recovery is directly dependent on power input.

Once enough alcohol has been recovered, the system can then be switched over to Extraction Mode to extract the next batch. The system is switched between these two modes to extract 2-3 runs a day.

Things to think about:

Approx. 0.5-1 gallon is lost per 7-10lbs of flower/leaf material.

The larger the heating and cooling systems are, the faster the unit can recover alcohol. Below are approximate recovery times based on power input. Power should be split 50/50 between heating and cooling systems.
