Abstract

The invention discloses a continuous countercurrent supercritical extraction apparatus, comprising an extraction kettle, a separation kettle and a gas cylinder, wherein the extraction kettle is communicated with the separation kettle via a first pipeline; the first pipeline is provided with a first heat exchanger; the bottom of the extraction kettle is provided with a gas inlet; the gas inlet is communicated with the gas cylinder via a second pipeline; the extraction kettle is provided with a raw material inlet; a spraying device is arranged at the raw material inlet; and the separation kettle is connected with the gas inlet via a third pipeline. The continuous countercurrent supercritical extraction apparatus provided by the invention is not shut down for addition of raw materials in the whole process of extraction and separation, cyclically utilizes CO2, avoids loss of CO2 and improves extraction and separation efficiency.

Description

technical field [0001] The invention relates to the technical field of supercritical extraction, in particular to a continuous countercurrent supercritical extraction device. Background technique [0002] Peony belongs to the shrub plant of Paeoniaceae of Ranunculaceae, which is a unique woody flower in my country. Peony seeds are the crystallization of the essence of peony plants, and also have their own unique nutritional components and medicinal value. The fatty acid composition of the extracted peony seed oil is relatively unique, and it is rich in a variety of beneficial trace components, which has the function of medical care. It is called a treasure among vegetable oils. In the extraction technology of peony oil, supercritical CO 2 Extraction technology is an environmentally friendly separation technology with strong solubility for fat-soluble components and high safety. It is an integrated technology with high efficiency and high yield. However, in the prior art, ...
