Problems solved by technology

Gansu Kushui Rose is the largest and most famous source of rose oil in China. The process of producing rose oil is: heating with direct fire, intermittent water distillation, steaming pot with a volume of 1.2 to 1.8 cubic meters, and steaming for 5 to 6 hours per pot. For every 3 pots of steaming, the first distilled water (twice the amount of flowers) is collected, and then intermittently re-distilled once. The daily processing of flowers is 300-360 kg. This distillation process is backward in technology, cumbersome in operation and less in flower amount. The flower peak period cannot be completely processed, resulting in the loss of flowers scrapped, time-consuming and labor-intensive, and the resulting rose oil is of poor quality, dark in color, and sometimes has a burnt smell Institute, 1988.6]
Gansu Kushui Rose uses the ancient distillation method, the cost of 1 kg of rose oil is as high as 30,000 yuan, and the oil yield is low, only 1.8-2.4 per ten thousand

Embodiment 1

[0026] The preparation of embodiment 1 rose oil of the present invention

[0027] Picking of roses: From 5:00 to 9:00 in the morning, there must be no smell or foreign matter mixed in. In principle, the flowers of the same day should be processed on the same day. If they are not finished on the same day, they should be stored in a cold storage to prevent the oily components of the flowers from volatilizing at high temperatures. The storage temperature should be 2-3 ° C, and the storage time should not exceed 48 hours. Otherwise, the oil yield will be greatly reduced.

[0028] One Distillation:

[0029] Add roses to a distillation kettle (3 cubic meters), about 500 kilograms, then add hot water or 1500 kilograms of secondary distillate, and the inlet pressure is 4kg / cm 2The steam is sent to the conical heating coil in the kettle, and the temperature inside the kettle rises from 60°C to 137°C at a heating rate of 3°C / min. The steam (produced by the flower and water mixture in...

Embodiment 2

[0042] The preparation of embodiment 2 rose oil of the present invention

[0043] Picking of roses: From 5:00 to 9:00 in the morning, pick buds that have not opened, and there must be no peculiar smell or foreign matter mixed in.

[0044] One Distillation:

[0045] Add roses to a distillation kettle (3 cubic meters), about 500 kilograms, then add hot water or 2000 kilograms of secondary distillate, and the inlet pressure is 4kg / cm 2 The steam is sent to the conical heating coil in the kettle, and the temperature inside the kettle rises from 60°C to 137°C at a heating rate of 4°C / min. The secondary steam (produced by the flower and water mixture in the kettle) enters the primary condenser (6 square meters) through the connecting pipe to condense, and the liquid storage tank collects condensate I 600kg each time, with a total amount of 1200kg, and the temperature of the condensate I is controlled at At about 30°C, enter the oil-water separator for separation to obtain 0.075 kg...

Abstract

The present invention relates to rose oil and its production process. The present invention uses rose of separated and screened Rosa Damascena Mill variety as material, and the rose oil contains cephrol 18-39 wt%, nerol 5-14 wt%, geraniol 14-29 wt%, paraffin 16-20 wt%, and phenylethanol <3.0 wt%. The present invention has high paraffin content and low phenylethanol content and scent lasting time as long as 48 hr, and features the sum of total geraniol and nerol content higher than cephrol content and thus special quality and scent. The present invention provides rose oil producing process with high production capacity, short processing time and rose oil yield as high as 0.035-0.050 %.

Description

technical field [0001] The invention relates to a rose oil and a production process thereof, and belongs to the field of extracting essential oils from plants. Background technique [0002] Rose oil, Rose oil, yellow or orange transparent flowing liquid, extracted from roses, with a refractive index of 1.4568-1.4776, a density of 0.8478-0.9140, an acid value of 1.52-5.90, and an optical rotation of -4.272-9.592. Rose oil, as a world famous spice, is used to prepare perfume, and is often used as a spice additive in candy, cakes, beverages, and champagne. Rose oil also has beauty and anti-aging effects. In recent years, the market demand for rose oil has been increasing year by year. [0003] Rose variety is the main factor determining the quality of rose oil. The main chemical components of roses are citronellol (rhoditol), geraniol, nerol, and phenylethyl alcohol. Different varieties of roses have different amounts of chemical components and their proportions, resulting i...
