Chrysanthemum essential oil is a natural oil extracted from chrysanthemum flowers, which has excellent cosmetic maintenance effects and is widely used in skin care products and soaps.
There are two common extraction methods for
chrysanthemum essential oil:
1. Water vapor distillation
Water vapor distillation is a commonly used
method for extracting essential oils from plants. The distillation equipment
has a large volume, and flowers concentrated in the flowering period can be
processed in large quantities, and the operation is simple and the cost is low,
so it is the main method for extracting essential oils from fresh flowers. This
method is suitable for the extraction of active ingredients that are volatile,
can be vaporized with water vapor without being destroyed, do not react with
water, and are difficult to dissolve in water.
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 the control of temperature and time, to ensure that only the pure
aroma of chrysanthemum extracted components.
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 extract or decompression distillation
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 will be 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 chrysanthemum essential oil.
1. Preparation of raw materials: Prepare
high-quality chrysanthemum petals, edible alcohol, distilled water, etc., wash
and dry the chrysanthemum.
2. Crushing: Crush the chrysanthemum
petals, generally using equipment such as mortar and pestle or blender, to
grind the petals into fine particles for subsequent operation.
3. Quality control: Before starting to
prepare essential oil, quality control and testing are required to ensure that
the quality and purity of the raw materials meet the requirements.
4. Extraction of essential oil: Put the
crushed chrysanthemum petals 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
chrysanthemum flavor are separated out to obtain pure chrysanthemum essential
oil. This process should be very careful and prudent, pay attention to the
distillation time and temperature to ensure that the distillation process is
carried out smoothly.
In the process of preparing chrysanthemum
essential oil, you need to use high quality chrysanthemum petals and other raw
materials, master certain preparation skills and operation 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.
