Pressing method (extrusion method)
Jan 30, 2019

     By cutting, pulverizing, and extruding, the water of the plant and the essential oil containing the aromatic component are separated from the raw material to obtain a mixture of water and oil, and then the oil and water are separated by centrifugation, filtration, etc., and the essential oil is obtained.

In the past, this traditional method of extracting essential oils in the general household is not only simple and convenient, but also ensures that the natural components of the essential oils are not destroyed during the extraction process. Plants such as citrus, lemon, bergamot, and lime will become odorous in the high temperature of water vapor, and it is not suitable to use steam distillation, so most of them are used.
