New Multifunctional Extraction Tank - Extracting Citronella Essential Oil from Lemongras

Citronella essential oil, also known as lemongrass essential oil or lemongrass oil, is an essential oil extracted by distillation from the lemongrass plant. It has a unique aroma and a variety of pharmacological activities, and is widely used in the fields of medicine, health care and beauty care. Citronella essential oil has powerful antibacterial and antiseptic properties, relieves anxiety and stress, eases muscle aches and pains, promotes digestion and relieves gastrointestinal problems, and improves skin health.

There are two common extraction methods for lemongrass essential oil:
1. Water vapor distillation
Water vapor distillation is a common method of extracting essential oils from plants, distillation equipment with a large volume, and easy to operate, low cost, is the main method of extraction of essential oils of flowers, herbs and teas. This method is suitable for volatile, can be vaporized with water vapor without being destroyed, and water does not react, but also difficult to dissolve in water for the extraction of active ingredients.
Will be fresh or dry treatment of aromatic plant raw materials into the distiller, add water to heat together, under the action of steam, the petals of terpenes, alcohols, lipids and other essential oils and water vapor evaporation, containing essential oils of the water vapor through the conduit to collect the cooling of the steam will be cooled into a liquid, and then in accordance with the difference in the density of the water and the essential oils are separated out. Using the essential oil components volatile, insoluble in water and do not react with water characteristics, condensation collection, and finally get the essential oil.
The distillation process needs to pay attention to control the temperature and time to ensure that only the pure aroma components of lemongrass extracted.
2. Solvent extraction method
Organic solvent extraction method is the use of volatile organic solvents, continuous reflux extraction or cold immersion, hot immersion extraction, etc. will dissolve the plant components, and then through the distillation of the extracted liquid or decompression distillation, etc. to remove the solvent can be obtained crude essential oil. The solvent extraction method is used to extract natural flavors from plant materials, and the yield of flavors obtained by this method is significantly increased.
Generally, the solvent and plant material into the extractor mixed extraction, so that the volatile substances dissolved in the solvent; and then filtered; subsequently, evaporation and concentration of the solvent to get the filtrate, the concentrate is called extract (wax, a mixture of essential oils); the extract is dissolved in ethanol, low-temperature filtration to remove impurities; and finally, evaporation of ethanol to get the essential oil.

The following is a detailed description of the preparation process of lemongrass essential oil.
1. Preparation of raw materials: prepare high-quality lemongrass, cooking alcohol, distilled water, etc., wash and dry the lemongrass.
2. Crushing: the lemongrass will be crushed, usually using a mortar and pestle or blender and other equipment, grinding into smaller particles of material for subsequent operations.
3. Quality control: before the preparation of essential oils, quality control and testing is required to ensure that the quality and purity of the raw materials meet the requirements.
4. Extraction of essential oil: Put the crushed lemongrass into the extractor and add ethanol and other solvents for extraction. The extraction time depends on the actual need, usually takes more than a few hours. During the extraction process, the extractor can be heated to increase the extraction speed.
5. Distillation: The extracted solution is subjected to distillation, through which the water and other impurities in the lemongrass flavor are separated out to obtain pure lemongrass essential oil. This process should be very careful and cautious, pay attention to the distillation time and temperature to ensure that the distillation process is carried out smoothly.

In the process of preparing lemongrass essential oil, you need to use high-quality lemongrass and other raw materials, to master certain preparation skills and operating methods, at the same time, high quality and professional essential oil extraction equipment is also essential.

Wenzhou Jinbang Light Industry Machinery Co., Ltd. of the new multi-function stainless steel extraction tank: a variety of styles and specifications, according to customer needs tailored solutions, factory direct sales, low temperature automatic extraction, high efficiency and high quality, professional manufacturers, 30 years of research and development experience, won the praise of customers.

Product Overview:
The extraction tank is filled with solvent, soaked and then heated by jacketed steam. Tank liquid boiling, according to the boiling point of each solvent is different, the beginning, the low-boiling component first boil into a secondary vapor through condensation, cooling to the oil-water separation, can be determined according to the process whether to reflux or discharge. The oil-water separator utilizes the different densities of oil and water to stratify the upper and lower layers, so as to obtain the volatile oil. In addition, due to the heating process, there is a concentration difference between the upper, middle and lower part of the liquid in the main tank, so that the liquid can be recycled from the bottom of the main tank through the filter and the pump back to the upper part of the main tank, realizing dynamic extraction.

This equipment is suitable for pharmaceutical, biological, beverage, food, chemical and other industries, plants, animals, atmospheric pressure, pressurization, decoction, warm immersion, thermal reflux, forced circulation, percolation, aromatic oil extraction and organic solvent recovery and other process operations, especially the use of dynamic extraction or multi-canister countercurrent extraction better, shorter time, high content of the liquid. Equipped with tanks equipped with CIP cleaning automatic rotary spraying ball, temperature gauge, pressure gauge, explosion-proof sight hole lamps, sight glass, quick-open feeding port, etc., to ensure easy operation, in line with GMP standards.
