A kind of low-temperature continuous phase change method for extracting the oil of the blue round trevally and the blue round trevally oil
The invention discloses a method of extracting decapterus maruadsi oil through low-temperature continuous phase transition and decapterus maruadsi oil.The method includes: placing decapterus maruadsi powdery raw materials in an extraction kettle; under conditions of extraction temperature of 40-60 DEG C and extraction pressure 0.3-1.0 Mpa, compressing an extraction agent into liquid, enabling the liquid to flow through the extraction kettle at a flow rate of 100-150 L / h for continuous extraction of 30-110 min, and after decapterus maruadsi oil is extracted, enabling the liquid to enter an analysis kettle with analysis temperature of 50-80 DEG C and analysis pressure of 0.1-0.4 Mpa; performing phase transition on the extraction agent to form gas, immediately compressing the gas into liquid, enabling the liquid to flow through the extraction kettle, extracting materials again, enabling the materials to carry oil to enter an analysis tank through a solvent of an extraction tank, and obtaining a decapterus maruadsi oil product after analysis.Compared with conventional extraction methods, the method is accurate and stable in process, the decapterus maruadsi oil is high in quality, extraction rate is increased remarkably, and efficient extraction of ocean low-value decapterus maruadsi oil is realized, so that cost can be saved, product yield can be increased, and economic benefit of production enterprises can be improved.
