Essential oils are gradually becoming a necessity for people's lives. There are many kinds of essential oils on the market, and their functions and effects are different. The function of essential oils is mainly to use volatile substances in plants, and the extraction of such important substances requires specialized equipment. Industrial large-scale production requires specialized extraction equipment and the steps are cumbersome. The practice teaching in middle school needs more consideration of the fun, operability and short-term efficiency of the experiment, and serves the more high-level biological experiment. Teaching, the essential oil extractor independently developed by Chuan Bran Bio was born under the research of many technicians.
The extraction method of essential oils can be summarized into the following three categories:
1. Steam distillation method: The volatile oil with strong volatility is carried out by using water vapor to form an oil-water mixture, and after cooling, the mixture is separated from the oil layer and the water layer. This method is the most widely used one.
2. Pressing method: The mechanical oil is pressed and the aromatic oil in the peel is pressed out. Suitable for the extraction of easy-to-focus paste raw materials.
3. Organic solvent extraction method: The aromatic oil is dissolved in an organic solvent, and the solvent is evaporated to obtain an aromatic oil. The particles of the raw material are required to be as small as possible and sufficiently immersed in the organic solution.

1. Heating with open flame 1. Using electric heating
2. Distillation takes 4-5h to see some oil droplets. 2. Distillation for 30min can see obvious oil droplets.
3. One-time distillation test material has less capacity 3. One-time distillation of 5-10 kg sample material
Essential oil extractor operation process:
1. Install the instrument and add distilled water without floating.
2. Cut the material as much as possible into the material basket covered with a layer of gauze. Place the material basket in the instrument and tighten the instrument cover bolts one by one.
3. Place a triangular bottle at the oil and water outlet to receive the oil-water mixture.
4. Pass tap water into the condenser and keep a small flow rate.
5. Turn on the power switch, adjust the power adjustment knob to the maximum, and the instrument enters the heating state.
6. When the oil-water outlet has an oil-water mixture flowing out, the power can be adjusted to control the distillation speed of the oil-water mixture.
7. Separate the essential oil with a separatory funnel.
Essential oil tips:
Plants containing volatile substances can be used as samples for the extraction of essential oils. Commonly used and rich in volatile substances are mint, orange peel, lavender, rose, and geranium. Essential oils are divided into four grades, namely pure dew, perfume grade, food grade, pure essential oil (low to high). The essential oil extracted by the essential oil extractor is an oil-water mixture. If it is not treated in depth, it can be used as a pure dew. It is not recommended to apply directly to the skin due to different personal qualities. Additional glycerin can be added to improve the affinity for the skin.
