Examples
Embodiment 1
[0029] Get water content and be 88.6% chlorella (chlorella) (prototheca oil content rate is 29.145% (dry basis)) algae liquid 400ml, then in chlorella algae liquid, drop acetic acid, adjust Ph value to be 5. Add the adjusted algae liquid into the high-pressure tank, then add high-pressure nitrogen into the high-pressure tank, so that the pressure in the high-pressure tank is maintained at 8MPa. Heat the high-pressure tank to 80°C, while the pressure rises to 10MPa, and maintain this condition for 2h. Then the material is discharged into the normal temperature and pressure tank, and the broken microalgae and algae oil remain in the normal pressure tank, and at the same time, a large amount of water is carried out of the normal pressure tank by nitrogen to achieve the effect of drying part of the microalgae. Then, the algae oil extraction rate was tested for the product collected in the vacuum tank, and the algae oil extraction rate was 86.8% after the wall was broken.
Embodiment 2
[0031] Get water content and be 88.6% different oxygen chlorella (chlorellavulga) (prototheca oil content rate is 29.145% (dry basis)) algae liquid 400ml, then drop sodium hydroxide solution in chlorella algae liquid, adjust Ph value for 9. Add the adjusted algae liquid into the high-pressure tank, then add high-pressure nitrogen into the high-pressure tank, so that the pressure in the high-pressure tank is maintained at 12MPa. Heat the high-pressure tank to 120°C while increasing the pressure to 15MPa, and maintain this condition for 10 minutes. Then the material is discharged into the normal temperature and pressure tank, and the broken microalgae and algae oil remain in the normal pressure tank, and at the same time, a large amount of water is carried out of the normal pressure tank by nitrogen to achieve the effect of drying part of the microalgae. Then, the algae oil extraction rate was tested for the product collected in the vacuum tank, and the algae oil extraction rat...
Embodiment 3
[0033]Get 400ml of chlorella vulga (chlorellavulga) (prototheca oil content rate 29.145% (dry basis)) algae liquid with a water content of 99.7%, then add sulfuric acid dropwise to the chlorella algae liquid to adjust the Ph value to 6. Add the adjusted algae liquid into the high-pressure tank, then add high-pressure nitrogen into the high-pressure tank, so that the pressure in the high-pressure tank is maintained at 12MPa. The high-pressure tank was heated to 110°C, and the pressure was raised to 14.5MPa at the same time, and maintained under this condition for 1h. Then the material is discharged into the normal temperature and pressure tank, and the broken microalgae and algae oil remain in the normal pressure tank, and at the same time, a large amount of water is carried out of the normal pressure tank by nitrogen to achieve the effect of drying part of the microalgae. Then, the algae oil extraction rate was tested for the product collected in the vacuum tank, and the algae...
