Hazelnut essential oil is a natural essential oil made from hazelnuts, which is rich in nutrients and has many benefits. Hazelnut oil has the efficacy and effectiveness of replenishing nutrients, laxative, assisting in improving the condition of the skin, assisting in improving memory, eliminating fatigue and other effects.
There are two common extraction methods for hazelnut essential oil:
1. Water vapor distillationWater vapor distillation is a common method of extracting essential oils of plants, distillation equipment with a large volume, and simple operation, low cost. This method is suitable for volatile, can be vaporized with water vapor without being destroyed, and water does not react, and difficult to dissolve in water for the extraction of active ingredients.
Fresh or dried aromatic plant materials into the distiller, add water to heat together, under the action of steam, the essential oils in the plant components and water vapor evaporation, containing essential oils of the water vapor collected by the conduit cooling 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. The use of essential oil components volatile, insoluble in water and do not react with water characteristics, condensation collection, and ultimately get the essential oil.
2. Solvent extractionOrganic solvent extraction method applies the principle of similarity and compatibility, due to the better solubility of oils and fats in organic solvents, through the full exchange of organic solvents and oils, oils and fats by the oil cells extracted from the method. The leaching method of preparing fats and oils has the advantages of high oil yield, low extraction temperature, high production efficiency, and suitability for large-scale production.
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, essential oil mixture); 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 hazelnut essential oil.
1. Prepare raw materials: prepare high-quality hazelnuts, cooking alcohol, distilled water, etc., wash the hazelnuts, dry.
2. Crushing: Hazelnuts are crushed, usually using a mortar and pestle or blender and other equipment, grinding into smaller particles for subsequent operations.
3. Quality control: Before starting to prepare essential oils, quality control and testing are required to ensure that the quality and purity of the raw materials meet the requirements.
4. Extraction of essential oils: The crushed hazelnuts are put into the extractor and ethanol and other solvents are added 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 hazelnut flavor are separated out to obtain pure hazelnut 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 hazelnut essential oil, you need to use high-quality hazelnut and other raw materials, 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. Oil-water separator utilizes the different densities of oil and water for upper and lower stratification, 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.
