Example

[0045] Embodiment 1——

[0046] Crush the dried wolfberry seeds to a particle size of 40 mesh, weigh 1 kg of wolfberry seed powder, and perform ultrasonic treatment with a power of 300W for 15 minutes; put it into a 500L extraction kettle for supercritical CO2 extraction. During supercritical extraction, set the temperature of the extraction kettle, separation kettle 1, and separation kettle 2 to reach 60°C, 55°C, and 50°C respectively; open the CO2 gas storage tank, and pressurize the extraction kettle. When the pressure of the extraction kettle reaches At 30MPa, open the valves that control the pressure of the separation kettle one and the separation kettle two, respectively adjust the pressure of the separation kettle one to 7.0MPa, and the pressure of the separation kettle two to 5.0MPa; at the same time, adjust the CO2 flow rate to be 30L / h; maintain the temperature and pressure , extract for 2 hours, and collect the extract every 20 minutes to obtain wolfberry seed oil.

Abstract

The invention discloses a method for supercritical carbon dioxide extraction of boxthorn seed oil. The method comprises the following steps: crushing boxthorn seeds until a particle size is 40-60 meshes, and carrying out ultrasonic treatment on the crushed material at a power of 100-300 W for 15-25 minutes; filling an extraction kettle with the treated material; adjusting the temperature of an extraction kettle to 50-60 DEG C, adjusting the temperature of a first separation kettle to 45-55 DEG C, and adjusting the temperature of a second separation kettle to 40-50 DEG C; opening a CO2 gas storage tank, pressurizing the extraction kettle, opening a pressure valve for controlling the first separation kettle and a pressure valve for controlling the second separation kettle when the pressure of the extraction kettle reaches 25-35 MPa, and adjusting the pressure of the first separation kettle to 6.5-7.5 MPa, and adjusting the pressure of the second separation kettle to 4.0-6.0 MPa; adjusting a CO2 flow to be 20 L/h to 35 L/h; conducting extracting for 2 hours; and regularly collecting an extract, wherein the extract is the boxthorn seed oil. The method is high in extraction rate, short in extraction time, short in production cycle, low in production cost, low in operation temperature and excellent in product quality, and effective components of the boxthorn seed oil can be well prevented from being damaged.
