Embodiment 1
[0015] Embodiment 1: 1.0 kilograms of tea seeds are put into the extraction kettle, feed CO 2 , the extraction temperature is 32°C, the pressure is adjusted to 22MPa, the extraction time is 90min, the flow rate is 50L / h, and CO is recovered after extraction 2 . The camellia oil extracted under this condition is clear in color and has no obvious impurities, and the extraction rate can reach 99%.
Embodiment 2
[0016] Example 2: Put 1.0 kg of tea seeds into the extraction kettle, pass through butane, the extraction temperature is 45°C, adjust the pressure to 0.8-1.0MPa, the extraction time is 40min, the flow rate: 50L / h and recover the butane after the extraction is completed alkyl. The camellia oil extracted under this condition is clear in color and has no obvious impurities, and the extraction rate can reach 99%.
