Embodiment 1
[0024] Follow the steps below to extract macadamia nut oil:
[0025] 1. Shell fresh macadamia nuts, crush the nuts to 20 meshes, dry them in an oven at 60°C to constant weight, weigh 1kg and place them in the barrel of a 2L extraction kettle;
[0026] 2. Turn on the refrigeration and cold cycle, and set the temperature of the water tank to 2°C;
[0027] 3. Turn on the heating power, set the extraction temperature to 45°C, the temperature of the separation kettle Ⅰ to 50°C, and the temperature of the separation kettle Ⅱ to 35°C;
[0028] 4. Fully open the cylinder valve, CO 2 Intake valve, CO 2 After the gas passes through the purifier, it enters the cold box for liquefaction. After the temperature reaches the set value, the CO is turned on. 2 pump, CO 2 The gas is pumped into the extraction kettle after passing through the purifier and heater, and the pressure is adjusted to 35MPa to make it into supercritical carbon dioxide. In the extraction kettle, it is fully contacted...
