Embodiment 1

[0030] A method for extracting Litsea Cubeba Oil, the specific process steps are:

[0031] (1) Fruit cleaning: wash the fresh fruit of litsea cubeba in a sink to remove impurities;

[0032] (2) Boiling water: Add clean water into the still pot, pass in steam with a pressure of 0.25Mpa, boil the water in the still pot, and discharge the air in the still pot;

[0033] (3) Feeding: Add the washed Litsea cubeba fresh fruit into the water in the still pot, and close the feeding valve;

[0034] (4) Distillation: Turn on the cooling water of the condenser, increase the steam flow rate, and control the steam pressure to 0.25Mpa. After the boiling gas is evaporated, cool the evaporated gas into a liquid, and control the steam volume and constant pressure to carry out water distillation. The distillation time is 1.2h;

[0035] (5) Oil-water separation: Send the condensed liquid into two series-connected oil-water separators, let it sit for precipitation to separate oil and water to ob...

Embodiment 2

[0042] A method for extracting Litsea Cubeba Oil, the specific process steps are:

[0043] (1) Fruit cleaning: wash the fresh fruit of litsea cubeba in a sink to remove impurities;

[0044] (2) Boiling water: Add distilled recovered water, distilled slurry standing water and clean water into the still, and introduce steam with a pressure of 0.2Mpa to boil the water in the still and discharge the air in the still;

[0045] (3) Feeding: Add the washed Litsea cubeba fresh fruit into the water in the still pot, and cover the feeding lid;

[0046] (4) Distillation: Turn on the cooling water of the condenser, increase the steam flow rate, and control the steam pressure to 0.2Mpa. After the boiling gas is evaporated, cool the evaporated gas into a liquid, and control the steam volume and constant pressure to carry out water distillation. The distillation time is 1.5h;

[0047] (5) Oil-water separation: Send the condensed liquid into two series-connected oil-water separators, let it...

Embodiment 3

[0054] A method for extracting Litsea Cubeba Oil, the specific process steps are:

[0055] (1) Fruit cleaning: wash the fresh fruit of litsea cubeba in a sink to remove impurities;

[0056] (2) Boiling water: Add distilled recovery water and or distilled slurry static water into the still, and introduce steam with a pressure of 0.3Mpa, boil the water in the still, and discharge the air in the still;

[0057] (3) Feeding: Add the washed Litsea cubeba fresh fruit into the water in the still pot, and close the feeding valve;

[0058] (4) Distillation: Turn on the cooling water of the condenser, increase the steam flow, and control the steam pressure to 0.3Mpa. After the boiling gas is evaporated, the evaporated gas is cooled to liquid, and the steam volume is controlled to carry out water distillation at a constant pressure. The distillation time for 1h;

Abstract

The invention discloses a method for extracting litsea cubeba oil. The whole fresh fruit of litsea cubeba is added in a boiling state, the steam pressure is 0.2-0.3MPa, and the water is distilled for 1-1.5h, the oil and water are separated to obtain litsea cubeba oil, and the liquid residue is separated , drying the combined seed cores to obtain dry litsea cubeba seed cores, and adding strains to the fruit puree to produce bio-organic fertilizers according to the usual method. Compared with the existing crushing or peeling technology, the present invention reduces the equipment investment for fresh fruit crushing or peeling, prevents litsea cubeba pulp from contacting with air, improves the oil yield and product quality, and the oil yield is 5.5-5.8%. The total aldehyde content reaches more than 75%. The by-product dried cubeb seeds are used as medicinal materials and food, and bio-organic fertilizers are used for forestry and agriculture, realizing resource recycling economy, shortening the production cycle, high equipment utilization rate, large processing capacity, energy saving and reduction consumption, reduces production costs, and has good economic, social and ecological benefits. Patents have good economic, social and ecological benefits.

Description

technical field [0001] The invention belongs to the technical field of fine chemicals and relates to a method for extracting litsea cubeba oil. Background technique [0002] Litsea cubeba ( Litsea cubeba ) is also known as pheasant pepper and wood ginger, and the traditional Chinese medicine name is Bicheng eggplant. It is a deciduous shrub or small tree of the genus Zingia lauraceae. It is an important spice and biomass energy tree species in southern my country. special status. Litsea cubeba volatile oil mainly exists in the fruit, and its skin, leaves, and flowers also contain volatile oil components, so the raw materials for extracting litsea cubeba oil mainly include the following forms: Litsea cubeba fruit, flowers, leaves, skin, The current extraction methods of Litsea cubeba volatile oil are steam distillation, Soxhlet extraction, microwave extraction and CO supercritical extraction. Tang Qingyun and others. Extraction and Utilization of Oil in Litsea Cubeba, Jour...
