Embodiment 1

[0032] Embodiment 1, extract rose essential oil, rose water and rose water extract from rose flower

[0033] Take 200kg of freshly picked roses and add demineralized water to soak for 2 hours at a mass ratio of 1:4, then beat to obtain rose pulp. The viscosity of the rose pulp is 15000cPs. The rose pulp is input from the feed inlet at the top of the SCC tower at a flow rate of 400L / h, and the temperature of the feed inlet is 90°C; the flow rate of water vapor input from the bottom is 80kg / h, and the temperature of the water vapor is 100°C. The rotating speed is 500r / min. The volatile aromatic components are carried out of the tower by the steam, and after condensation, the rose oil-water mixture is obtained, and then placed in an oil-water separator for stratification. The upper layer obtains 30mL rose essential oil, and the lower layer obtains 20kg rose water.

[0034] At the same time, due to physical inertia, the flower pulp flows from the fixed cone fixed on the inner wal...

Embodiment 2

[0035] Embodiment 2, extract rose essential oil, rose flower water and rose water extract from rose flower

[0036] Take 300kg of freshly picked roses and add demineralized water to soak for 1 hour according to the mass ratio of 1:6, and then beat to obtain rose pulp. The viscosity of rose pulp is 10000cPs. The flower pulp is input from the feed inlet at the top of the SCC tower at a flow rate of 500L / h, and the temperature of the feed inlet is 100°C; the flow rate of water vapor input from the bottom is 100kg / h, the temperature of the water vapor is 110°C, and the rotating cone speed 750r / min. The volatile aromatic components are taken out of the tower by the steam, and after condensation, the rose oil-water mixture is obtained, and then placed in the oil-water separator to stand for stratification. The upper layer obtains 50mL rose essential oil, and the lower layer obtains 450kg rose water.

Abstract

The invention discloses a method for extracting rose essential oil, rose water and a rose aqueous extract from fresh rose flowers. The method includes the following steps: (1) soaking freshly picked roses with softened water; (2) beating the system obtained in the step (1) to obtain a flower slurry; (3) sending the flower slurry from a feeding port of a rotating cone distillation column into the body and introducing steam from the bottom of the rotating cone distillation column, wherein the steam extracts volatile aroma components in the flower slurry during the rising process, then moves out of the rotating cone distillation column and is condensed to obtain a rose oil-water mixture; and acquiring the rose dreg and liquid mixture from the bottom of the rotating cone distillation column; (4) conducting oil and water separation on the rose oil-water mixture to obtain an upper layer separating medium rose essential oil and a lower layer separating medium rose water; and (5) filtering the rose dreg and liquid mixture to obtain a filtrate, and concentrating the filtrate to obtain the rose aqueous extract. The invention can avoid the degradation of recycled aroma substances or raw materials and solve the problem that steam distillation method for extracting essential oil produces stewing smell.

Description

technical field [0001] The invention relates to a method for extracting rose essential oil, rose water and rose water extract from rose flowers. Background technique [0002] Rose (Rosa rugosa thunb.) is an upright deciduous shrub in the Rosaceae family (Rosaceae). It has bright colors, pleasant aroma and high oil content. It is an important special economic plant in my country. It is an important raw material for wood and food industry, spice industry, etc. The medicinal use of roses has a history of more than two thousand years in my country. "Materia Medica Justice" records: "The fragrance of roses is the strongest, clear but not turbid, harmonious but not fierce, softening the liver and refreshing the stomach, promoting qi and blood, and there are almost no other fragrances." Modern pharmacological analysis shows that roses contain phenols, phenylethyl alcohol, nerol, organic acids, red pigments, yellow pigments, waxes, and carotene. [0003] Rose essential oil is a na...
