Embodiment 1

[0015] Step 1: remove impurities from the peony seeds, put them into the sieving equipment, put the sieved peony seeds into the drying equipment, heat them to 66°C, dry them for 18 hours, put them into the crushing equipment, crush them and sieve them to obtain 65 mesh peony seeds scrap, spare;

[0016] Put 280kg peony seed fragments into the extraction kettle and start the extraction. The extraction temperature is 50°C, the extraction pressure is 27Mpa, and the extraction time is 145min. Close the extractor, check to ensure that it is tightly sealed, and use a high-pressure pump to remove the liquid CO2 in the storage tank. Pump into the vaporizer, gasify into a critical fluid state, and then enter the extractor to extract the peony seed fragments. Set the pressure in the extractor to 18Mpa and the temperature to 38°C. The mixed fluid of extracted CO2 and peony seed essential oil Enter the separator for decompression separation, the carbon dioxide flow rate is 27kg / h, the pre...

Embodiment 2

[0020] Step 1: remove impurities from the peony seeds, put them into the sieving equipment, put the sifted peony seeds into the drying equipment, heat them to 77°C, dry them for 10 hours, put them into the crushing equipment, crush them and sieve them to obtain 60 mesh peony seeds scrap, spare;

[0021] Put 380kg peony seed fragments into the extraction kettle and start the extraction. The extraction temperature is 47°C, the extraction pressure is 26Mpa, and the extraction time is 145min. Close the extractor, check to ensure that it is tightly sealed, and use a high-pressure pump to remove the liquid CO2 in the storage tank. Pump into the vaporizer, gasify into a critical fluid state, and then enter the extractor to extract the peony seed fragments. Set the pressure in the extractor to 13Mpa and the temperature to 38°C. The mixed fluid of extracted CO2 and peony seed essential oil Enter the separator for decompression separation, the carbon dioxide flow rate is 27kg / h, the pre...

Abstract

The invention relates to a supercritical extraction method for peony seed essential oil. The method employs cleaning, drying, crushing, supercritical extraction, and then molecular distillation. The operating temperature is low, the heating time is short, grease oxidation and rancidification caused by high temperature can be avoided, and the separation degree and product yield are high, and molecular distillation can also reduce the acid value of grease. The method realizes the purposes of efficient extraction, separation, no impurity, and high purity of extraction product, the operation process is simple, the extraction time is short, the cost is reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of extraction of peony seed essential oil, in particular to a supercritical extraction method of peony seed essential oil. Background technique [0002] Luoyang is particularly rich in peony resources. Because peony is native to the Central Plains and has a long history of cultivation, Luoyang is the hometown and birthplace of Chinese peony. Peony is a unique and precious flower in my country. The reputation of "king of flowers" has been regarded as a symbol of wealth, auspiciousness and prosperity since ancient times. "Luoyang's ground vein flowers are the most suitable, and peonies are especially rare in the world", so it is also called "Luoyang flower". Luoyang flowers began in the Jin Dynasty, flourished in the Tang Dynasty, and became the best in the world in the Song Dynasty. It has a history of more than 1,600 years. Peony not only has ornamental value, but also has high health, beauty and medicinal ...
