| 中文摘要: |
| 油脂的氧化酸败速度与溶于油脂中的氧量有关，油脂的吸氧量可达其体积的15%~150%或质量的0.02%~0.2%，利用溶气泵的高强度气液混合特性，将99.99%的氮气在氮气压力0.05~0.15 MPa、流量5.0~150.0 L/min条件下，与植物油进行充分循环混合12~24 h，强行替换、排出油脂中吸收的氧气，以提高植物油的储存稳定性，并有效防止PET包装瓶的瘪瓶现象。 |

| The oxygen dissolved amount in oil associated with oxidative rancidity speed of oil, and oxygen absorbed by oil could reach 15%-150% of its volume or 0.02%-0.2% of its mass. Using the high strength characteristics of gas-liquid mixed pump 99.99% of nitrogen gas under the conditions of pressure 0.05-0.15 MPa and flow rate 5.0-150.0 L/min were fully mixed with vegetable oil for 12-24 h, forcing the replacement and dischargement of oxygen absorption in oil, in order to improve the storage stability of vegetable oil, and effectively prevent the phenomenon of flat bottle of PET bottles. |
