With heat of the steam, the plant material starts releasing the oil content (that is present in the plants), which flows along with the steam and then this steam is suddenly cooled with cold water in condenser pipe, as this steam cools down, the condenser pipe is let into the tank full of cold water, where it releases the oil particles that it carried from the plant material into the water tank. Now the oil is collected from the water surface. This is pure Essential oil & does not contain any fats or lipds.
