Agarwood Essential Oil Steam Distillation Apparatus

Agarwood essential oil is extracted from precious agarwood after distillation and extraction, and is the essence of agarwood. Agarwood essential oil has multiple effects on the human body, such as improving aura, relieving stress, sleeping and anti-depression, regulating body and mind, and promoting body metabolism. Dropping a few drops of agarwood essential oil into the hot water for foot bathing can achieve the purpose of activating blood circulation and meridians, and can also achieve the effect of removing athlete's foot and foot odor. Due to the non-renewable nature of natural agarwood, the refined agarwood oil is even more rare and precious.

The extraction method of agarwood essential oil usually adopts distillation technology. First, the precious agarwood wood is placed in the distiller, and the aromatic components in the wood evaporate during the heating process. Subsequently, these vapors are cooled by the cooling system to condense into liquid. This process is called distillation extraction, which is a key step in refining agarwood essential oil. The yield of this essential oil is relatively low, and its weight is usually between one and two ten-thousandths of the weight of the original agarwood raw material.

Agarwood essential oil can be divided into new oil and aged oil according to the year of extraction. Newly extracted agarwood essential oil may have a strong smell at first, with a certain spicy feeling and a more complex smell. However, as time goes by, its fragrance will gradually become more gentle, the layering will be more obvious, and it will last longer and not easily dissipate.

The advantages of ancient distillation include:

The distilled agarwood essential oil is rich in volatile oil organic aromatic hydrocarbon components, and the aroma is rich and domineering.

Essential oils with small molecular structures have higher energy and greater use value.

The purity and quality of the by-product hydrosol are better than other extraction methods

I. Steam distillation method

Steam distillation is one of the most commonly used methods for extracting agarwood essential oil. The specific steps are as follows:

1. Crush the agarwood and put it into the distillation kettle.

2. Seal the distillation kettle and pass steam for heating.

3. After steam heating, the agarwood essential oil in the agarwood is volatilized and enters the condenser with the steam.

4. The agarwood essential oil is cooled and solidified in the condenser to form two layers of oil and water, which can be separated with a separatory funnel.

II. Microwave-assisted extraction

Microwave-assisted extraction is a fast and efficient method for extracting agarwood essential oil. Its advantages are short extraction time, high purity of essential oil, energy saving and environmental protection, etc.

1. Put the agarwood powder into the extractor.

2. Add water or organic solvents and other extractants.

3. Volatilize the agarwood essential oil by heating with microwave radiation.

4. Sediment the extract to separate the oil and water layers.

It should be noted that when using the above method to extract agarwood essential oil, the following matters should be noted:

1. The time and area selection for harvesting agarwood are key factors affecting the quality of agarwood essential oil.

2. The extractor should be clean and hygienic to avoid interference from other substances.

3. The temperature and pressure should be controlled during extraction, and should not exceed the volatilization point of agarwood essential oil.

4. It is not recommended to use solvents that are difficult to volatilize, which are easy to remain in the agarwood essential oil.

5. The obtained agarwood essential oil should be stored carefully to avoid direct sunlight and high temperature environment.

In short, agarwood essential oil is a natural essential oil with important application value. It is widely used in plaster preparations, cosmetics, fragrances and mood regulation. Selecting the appropriate extraction method and paying attention to the operating details can obtain high-quality agarwood essential oil.
