Cormorant coupled with cooler (condenser), then reheated. Water flow into the condenser and it should be maintained so that it continues to flow. Condenser temperature can be kept cold by adding ice, so that all components that evaporate condensed and not loss into the air. Distillate obtained is a mixture of water and extract and then divided in a separating funnel. For complete separation, distillate is added by sodium chloride (NaCl) in order to remove emulsified components. Water phase is processed again because it still contains small amount of emulsified products. This work is repeated until all the product separated.
