[0024] Example 1
[0025] A method of extracting Antarctic krill oil based on low-temperature continuous phase change technology, including the following steps:
[0026] S1 uses the antidepole krill powder, and the temperature of the heating dryer is used to dry at about 30 ° C, and the moisture content is ≤10%.
[0027] S2 The Antanzoleum powder treated step S1 is 1.0 kg, which is loaded into the extractor of the continuous phase change extraction device, and 3 l is added to 3 h.
[0028] S3 The extracted kettle described in step S2 is compressed into a liquid under the extraction temperature of 0.45 MPa, and the n-butane is compressed into a liquid, flowing through the extract in the flow rate of 60 l / h, and extracts 10 min, extracting the krill. After the oil enters the parsing, analyze the temperature of 60 ° C, analyze the pressure of 0.25 MPa; by heating, the positive butane phase changes into a gas, and then the liquid flows through the extracted kettle, and the material ...
