Embodiment Construction

[0015] The following provides embodiments for implementing the present invention, but not limited to this embodiment:

[0016] A production method for preparing essential oil from the plant mugwort is provided. The steps are as follows:

[0017] 1. Select 30 kg of fresh mugwort, remove impurities and dry in the shade for 3-5 days, cut into short stems within 10 mm, weighing 21.5 kg;

[0018] 2. Put 21.5 kg of Mugwort raw material into a jacketed heating reactor containing 10 kg of 10% Mugwort essential oil. Heat up to 70°C for one hour to keep the raw material initially dissolved; press the mixture into the connecting rod with an air compressor to press Pressed with a machine to obtain 17.4 kg of mugwort essential oil-water mixture and 13.6 kg of waste residue. The content of mugwort essential oil is 11.2% (the net content of mugwort essential oil is 1.95 kg);

[0019] 3. The crude mugwort hydrated mixture should be coarsely filtered to remove impurities, stored in a stainless steel c...

Abstract

The invention aims to provide artemisia argyi essential oil production process which can shorten production process procedures, lowers production cost, and is safe, environmental-friendly, relatively lower in the requirement on workers' quality and easy to process slag. The production method can realize continuous and mass production of artemisia argyi essential oil, and comprises the following steps: 1. pretreatment of the artemisia argyi; 2, pressing of artemisia crude oil; 3, standing and layering of artemisia argyi crude oil hydrate; 4, rectification of artemisia argyi essential oil, namely a hydration liquid containing the artemisisa argyi at the upper part of the stood and layered artemisia argyi crude oil hydrate is led to the rectification procedure for rectification, as a result, the artemisia argyi is obtained. The slag is treated, the slag contains organic substances, and the pressed slag is shattered so as to obtain a raw material containing more than 45 percent of organic substances.

Description

Technical field [0001] The invention relates to a method for producing essential oils of plants, in particular to a method for producing essential oils of artemisia wormwood through physical squeezing processing and high-temperature rectification separation by using plant wormwood as raw materials. [0002] Background technique [0003] At present, the main methods for domestic production of mugwort essential oil are steam distillation, organic solvent extraction, and carbon dioxide supercritical extraction. [0004] The steam distillation method has a long production process line, the distillation process is controlled on the plant mugwort, the distillation time is long, the product composition is complex, the yield is low, the generated waste residue is not easy to break, and the effective ingredients cannot be completely extracted. [0005] In the organic solvent extraction method, the organic solvents used are generally methanol and acetone. After these chemical organic solvents e...
