Plant essential oil extraction method

Abstract

The invention belongs to the technical field of phytoextraction, and particularly relates to a plant essential oil extraction method, which comprises step 1 to step 7, step 1 to step 4 are mutually matched to perform first-time leaching on petals; step 5 to step 7 are used for performing second-time leaching on the petals. Leaching devices adopted by the invention comprises a leaching tank and a concentrating tank, a fixed barrel is fixedly arranged in the leaching tank, and a stirring unit is arranged in the fixed barrel; a No.3 opening and a No.4 opening are formed in a lower bottom plate ofthe leaching tank; the No.3 opening and the No.4 opening are used for conveying liquid in the leaching tank to the fixed barrel through matching with a No.1 dump pump; the stirring unit comprises a hollow rotating rod, hollow steel balls and hollow rubber tubes. The plant essential oil extraction method is mainly used for extracting essential oil from violet petals, the petals can be leached by using leached grease, the leaching efficiency of the petals can be accelerated by using steam generated during leach liquor concentration, and the leaching efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of plant extraction, in particular to a plant essential oil extraction method. Background technique [0002] Plant essential oils are the unique aromatic substances extracted from plants, which are extracted from the flowers, leaves, roots, bark, fruits, seeds, resins, etc. of herbal plants by distillation and pressing. Because aromatherapy essential oils are highly volatile and have small molecules, they are easily absorbed by the human body and can quickly penetrate into the internal organs of the human body to excrete excess components. The whole process only takes a few minutes, and the fragrance of the plant itself also directly stimulates the brain. The secretion of the pituitary gland, the secretion of enzymes and hormones, etc., balance the functions of the body, and play the role of beauty and skin care. Compared with the chemically synthesized plant essential oils, the naturally extracted plant ess...

Problems solved by technology

Because aromatherapy essential oils are highly volatile and have small molecules, they are easily absorbed by the human body and can quickly penetrate into the internal organs of the human body to excrete excess components. The whole process only takes a few minutes, and the fragrance of the plant itself also directly stimulates the brain. The secretion of the pituitary gland, the secretion of enzymes and hormones, etc., balance the functions of the body, and play the role of beauty and skin care. Compared with the chemically synthesized plant essential oils, the naturally extracted plant essential oils have the characteristics of non-toxic and side effects; Alcohol is very inefficient in extracting essential oils from plant tissues. Since the polarity of oils in plants is weak, and ethanol is polar, a method is needed to extract plant tissues using oils in plant tissues.
