Description

Technical Field

[0001] The invention relates to rose essential oil, in particular to a supercritical extraction rose essential oil and a rotating preparation component and a preparation process, belonging to the technical field of rose essential oil. Background Art

[0002] Traditional rose essential oil is extracted by steam extraction, which is easy to operate and low in cost, but the extraction rate is low, resulting in high prices;

[0003] The extraction rate of organic solvent extraction is relatively high, but since organic solvents are easy to remain in the essential oil and cause greater environmental pollution, the scope of use of rose essential oil is limited, especially in some cosmetics due to the existence of the above problems, rose essential oil cannot be well used;

[0004] In the prior art, the extract and the rose whitening cream product are not mixed evenly and the mixing efficiency is low. Therefore, a supercritical extraction of rose essential oil and a rotating preparation component and a preparation process are designed to solve the above problems. Summary of the invention

[0005] The main purpose of the invention is to provide a supercritical extraction rose essential oil and a rotating preparation component and a preparation process.

[0006] The purpose of the present invention can be achieved by adopting the following technical solutions:

[0007] A supercritical extraction rose essential oil comprises rose petals, sweet almond oil, wheat germ oil, grape seed oil and jojoba oil.

[0008] A supercritical extraction process for preparing rose essential oil comprises the following steps:

[0009] Step 1: Select the rose petals, pick the non-rotten parts, remove impurities, dry to a moisture content of 10%-30%, crush, and put into the supercritical equipment extraction kettle to ensure that it does not exceed 2 / 3 of the tank volume;

[0010] Step 2: Connect the supercritical equipment, and pump the supercritical CO2 gas into the extraction kettle under the action of the booster pump. The extraction pressure of the raw material in the extraction kettle is 8-30MPa, the extraction temperature is 35-50℃, and the extraction time is 1-3h. At this time, CO2 is in a supercritical fluid state. Open the air valve between the extraction kettle and the essential oil separation kettle to allow the CO2 fluid in the supercritical state in the extraction kettle to carry the essential oil components into the essential oil separation kettle;

[0011] Step 3: Add sweet almond oil, wheat germ oil, grape seed oil, and jojoba oil in a ratio of 1-5:1 by weight of roses into the essential oil separation kettle, and mix them at will according to the requirements of subsequent cosmetics. The rose essential oil is mixed into the oil and fixed by the oil;

[0012] Step 4: Open the water inlet and outlet valves at the upper end, connect deionized water to enter the hydrosol separation kettle, not exceeding 1 / 2 of the tank volume, open the air valve between the essential oil separation kettle and the hydrosol separation kettle, remove the CO2 of the essential oil and enter the hydrosol separation kettle in a gaseous state, and a small amount of essential oil enters the hydrosol separation kettle in a gaseous state in the separation kettle, and is dissolved in water under the synergistic effect of CO2 gas. When it reaches supersaturation in the water, a saturated aqueous solution is formed. The remaining supercritical CO2 gas is filtered by water in the hydrosol separation kettle, recovered into the CO2 tank, and reused;

[0013] Step 5: The rose is extracted 3-4 times by supercritical extraction, and the extraction time decreases in sequence of 1h, 0.8h, 0.6h, and 0.4h. Since the rose essential oil extracted by supercritical extraction contains wax, the flow rate is increased when it is extracted by supercritical CO2 circulation, and the rose essential oil and the material in the separation kettle are well combined. After the extraction, the extract can be directly used in the rose whitening cream product, the material mixing is more even, and the subsequent processes are also reduced.

[0014] A supercritical extraction and rotation preparation component for rose essential oil.

[0015] Beneficial technical effects of the present invention:

[0016] The invention provides a supercritical extraction rose essential oil and a rotating preparation component and a preparation process. The ultrasonic generator is arranged at the bottom of the box body, so that the mixture can be mixed by ultrasonic waves during use, and there is no dead angle in the mixing, thereby improving the mixing rate and effect. In addition, by arranging the horizontal partition and the cross-shaped partition inside the frame, the mixture can be collided with the horizontal partition and the cross-shaped partition to improve the mixing efficiency, and the limiting is more convenient and the practicability is higher.

[0017] The setting of the sleeve at the top of the placement frame utilizes the rotational connection between the sleeve and the mounting plate, and then utilizes the rotating mechanism composed of the tooth block on the outside of the sleeve, the motor, and the driving gear to control the rotation of the placement frame, so that the parts to be cleaned can be mixed by rotation after being taken out of the solution.

[0018] Through the innovation of supercritical extraction, the raw materials for downstream production of rose essential oil can be directly obtained, which not only solves the problem of low yield but also has no solvent residue, thus solving the above problems very well.

[0028] Step 1: Select the rose petals, pick the non-rotten parts, remove impurities, dry to a moisture content of 10%-30%, crush, and put into the supercritical equipment extraction kettle to ensure that it does not exceed 2 / 3 of the tank volume;

[0029] Step 2: Connect the supercritical equipment, and pump the supercritical CO2 gas into the extraction kettle under the action of the booster pump. The extraction pressure of the raw material in the extraction kettle is 8-30MPa, the extraction temperature is 35-50℃, and the extraction time is 1-3h. At this time, CO2 is in a supercritical fluid state. Open the air valve between the extraction kettle and the essential oil separation kettle to allow the CO2 fluid in the supercritical state in the extraction kettle to carry the essential oil components into the essential oil separation kettle;

[0030] Step 3: Add sweet almond oil, wheat germ oil, grape seed oil, and jojoba oil in a ratio of 1-5:1 by weight of roses into the essential oil separation kettle, and mix them at will according to the requirements of subsequent cosmetics.
