Embodiment 1

[0016] Step 1: Select the peony seeds, wash them with water to remove impurities and soil, select the peony petals with good luster and wash them with water, the ratio of peony seeds to peony petals is 6:1, and drain the washed peony seeds and peony petals The water is ready for use. Put the dried peony seeds and peony petals into the solar drying equipment for drying. There is a temperature sensor in the drying room to ensure that the drying temperature in the drying room is between 65°C and the drying time After 4 hours, the water content is less than 7%, and the dried peony seeds and peony petals are crushed into bran by crushing equipment to obtain peony seeds and peony petals for later use;

[0017] Put 380kg of peony seeds and peony petal fragments into the extraction kettle, and start the extraction. The extraction temperature is 41°C, the extraction pressure is 27Mpa, and the extraction time is 145min. Close the extractor, check to ensure that it is tightly sealed, and ...

Embodiment 2

[0021] Step 1: Select the peony seeds, wash them with water to remove impurities and soil, select the peony petals with good luster and wash them with water, the ratio of peony seeds to peony petals is 8:1, and rinse the peony seeds and peony petals to dry The water is ready for use. Put the dried peony seeds and peony petals into the solar drying equipment for drying. There is a temperature sensor in the drying room to ensure that the drying temperature in the drying room is between 68°C and the drying time In 7 hours, the moisture content is less than 7%, and the dried peony seeds and peony petals are crushed into bran by crushing equipment to obtain peony seeds and peony petals for later use;

Abstract

The invention discloses a peony essential oil supercritical CO2 extraction method. The method comprises the steps of washing, drying, grinding, supercritical extraction, and molecular distillation, and has the advantages that the operation temperature is low, the heating time is short, the grease oxidation and rancidity caused by high temperature can be avoided, moreover, the separation degree and product yield are high, the acid value of grease is reduced by the molecular distillation; high efficient extraction and separation can be achieved, the essential oil does not contain any impurity, the purity of the extraction product is high, the operation and technology are 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 extracting peony seed oil, in particular to a supercritical CO extraction method for peony essential oil. 2 extraction method. Background technique [0002] Luoyang is particularly rich in peony resources. Because peony is native to China 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.
