Embodiment 1

[0021] A method for comprehensively utilizing orange peel, comprising the following steps:

[0022] (1) Dry the fresh citrus peels in the sun, soak them in 3% brine for 10 hours, filter, take out the citrus peels and freeze-dry them at -20°C for 18 hours;

[0023] (2) Put the freeze-dried citrus peel into the distillation tank, and then pass it into the steam distillation for 4 hours to obtain the mixed steam;

[0024] (3) The mixed steam is condensed through a condenser, and then separated from oil and water through an oil-water separator to obtain orange peel crude oil;

[0025] (4) Put the crude orange peel oil at a temperature of 5°C for 24 hours and filter to obtain the orange peel essential oil.

Embodiment 2

[0027] A method for comprehensively utilizing orange peel, comprising the following steps:

[0028] (1) Dry fresh citrus peels in the sun, soak them in 4% brine for 10 hours, filter, take out the citrus peels and freeze-dry them at -10°C for 10 hours;

[0029] (2) Put the freeze-dried citrus peels into the distillation tank, and then add steam to distill for 5 hours to obtain mixed steam;

[0030] (3) The mixed steam is condensed through a condenser, and then separated from oil and water through an oil-water separator to obtain orange peel crude oil;

[0031] (4) Put the crude orange peel oil at a temperature of 8°C for 30 hours and filter to obtain the orange peel essential oil.

Embodiment 3

[0033] A method for comprehensively utilizing orange peel, comprising the following steps:

[0034] (1) Dry fresh citrus peels in the sun, soak them in 3% brine for 8 hours, filter, take out the citrus peels and freeze-dry them at -30°C for 12 hours;

[0035] (2) Put the freeze-dried citrus peel into the distillation tank, and then pass through the steam for 3.5 hours to obtain the mixed steam;

[0036] (3) The mixed steam is condensed through a condenser, and then separated from oil and water through an oil-water separator to obtain orange peel crude oil;

[0037] (4) Put the crude orange peel oil at a temperature of 10°C for 48 hours and filter to obtain the orange peel essential oil.

Abstract

The invention discloses a method for comprehensively using orange peels. The method comprises the steps: drying fresh orange peels, soaking in salt water for 8 to 12 hours, filtering, taking out the orange peels, and freeze-drying at a low temperature for 10 to 18 hours; putting the freeze-dried orange peels into a distillation tank, introducing steam to distill for 3 to 5 hours, and getting mixed steam; condensing the mixed steam through a condenser, conducting oil-water separation through an oil-water separator, and getting orange peel crude oil; standing the orange peel crude oil at low temperature, filtering, and getting orange peel essential oil. The orange peel essential oil extracted by the invention has a sweet orange aroma and can be applied in the fields of cosmetics, medicine and the like. The market prospect is good, and the abandoned orange peels are used comprehensively and reasonably, and have good economic benefit, ecological benefit and social benefit.

Description

technical field [0001] The invention relates to the field of comprehensive utilization and extraction of waste, in particular to a method for comprehensive utilization of orange peel. Background technique [0002] Our country has a great demand for citrus each year, and citrus peels are usually discarded. Of course, orange peel has traditional Chinese medicine properties after being dried, and only a very small part is used as medicine. Citrus peels generally contain 2-3% essential oils, from which essential oils can be extracted. However, there is no relevant report on extracting essential oil from citrus peel. [0003] Most of the existing extraction methods for essential oils are mainly steam distillation and organic solvent methods. The existing water vapor has problems such as low extraction rate, long time consumption, and low product purity. The solvent method not only needs to remove the leaching solvent, but also uses There is a high amount of residual solvents i...
