Problems solved by technology

[0015] In the crushing process, the mesh size of the crushed cypress raw material is too large, which will greatly affect the quality and quantity of fendol and essential oil extracted from cypress
[0016] There is no decolorization and decoking process in the whole method, which will result in poor quality of extracted phytoncine and essential oil

Embodiment 1

[0036] The method for extracting phytoncide and essential oil from cypress, the specific steps are as follows:

[0037] ① Raw material selection process: The perennial woody juniper rhizomes of mature cypress and yellow juniper are washed with a high-pressure water gun to remove impurities such as sand and soil on the surface.

[0038] ②Drying process: bake the raw materials described in ① until the water content is 8%.

[0039] ③Crushing process: Cut with a mechanical guillotine into dry wood chips with a length of 6 cm, a width of 2 cm, and a thickness of 0.2 cm, and finely crush the dry wood chips of juniper wood to make it into a 10-mesh particle powder, and put it into the middle of the retort.

[0040] ④Low-pressure steam process: 75°C water vapor is generated in the steam generator, enters from the steam inlet of the lower part of the distillation tank, and briefly contacts with the filled cypress raw material. After 30 seconds, start the oil pump to evacuate to generat...

Embodiment 2

[0051] The method for extracting phytoncide and essential oil from cypress, the specific steps are as follows:

[0052] ① Raw material selection process: The perennial woody juniper rhizomes of mature cypress and yellow juniper are washed with a high-pressure water gun to remove impurities such as sand and soil on the surface.

[0053] ②Drying process: bake the raw materials mentioned in ① until the water content is 9%.

[0054] ③Crushing process: Cut with a mechanical guillotine into dry wood chips with a length of 7 cm, a width of 3 cm, and a thickness of 0.3 cm, and finely crush the dry wood chips of juniper wood to make it into a 30-mesh particle powder, and put it into the middle of the retort.

[0055] ④Low-pressure steam process: 85°C water vapor is generated in the steam generator, enters from the steam inlet of the lower part of the distillation tank, and briefly contacts with the filled cypress raw material. After 50 seconds, start the oil pump to evacuate to generate ...

Abstract

The invention discloses a method for extracting phytoncide and essential oil from cypress. The method particularly includes steps of (1) raw material selection procedure; (2) drying procedure: dryingthe raw material in step (1) until the water content is less than 10%: (3) smashing procedure: making the raw material become 10-30 meshes of granular powder, and filling in the middle part of the distilling tank; (4) low-pressure steam procedure: generating steam at 75-85 DEG C in the steam generator, starting an oil pump after 30-50 seconds to vacuumize and generate 40-60kpa negative pressure; (5) distilling procedure: finally, changing the negative pressure to normal air pressure; (6) filtering procedure; (7) decoloring and decocking procedures; (8) oil water separating procedure. The method is the improvement of a traditional wet distillation and depressurized distillation method, and is particularly suitable for the essential oil extraction taking perennial cypress stems as the raw materials; the method can avoid massive pyrolysis, hydrolysis and cocking phenomenon in the production process.

Description

technical field [0001] The invention relates to the field of extracting phytondine and essential oil, in particular to a method for extracting phytondine and essential oil from juniper. Background technique [0002] Phytondoline usually refers to the pure natural defensive organic components contained in higher plants, which are mainly terpenes, which can be fragrant and fragrant when smelled. Fentorine can expel micro-worms, bacteria and viruses that harm plants, and promote the repair of damaged parts of plants. Juniper phytoncide generally refers to the aqueous solution separated during the extraction of juniper essential oil, that is, pure dew. [0003] Essential oils are volatile aromatic substances extracted from the flowers, leaves, stems, roots or fruits of plants through steam distillation, extrusion, cold soaking or solvent extraction. Juniper contains a lot of essential oils and phytondine, which can be extracted and used by people, which is helpful to people’s ...
