摘要
采用均匀设计试验方法,研究了微波处理低含油乳化液的脱油率与微波辐射功率、脱油温度、油的质量分数之间的关系,并应用MATLAB编程拟合出相应的经验公式,回归效果显著。结果表明,脱油率随微波辐射功率的增大呈负指数规律增加,随脱油温度的升高呈线性增加,随油的质量分数的增加呈2次关系减小;脱油温度与油的质量分数存在交互效应,含油率的升高会减小脱油温度对脱油率的影响,而脱油温度的升高会增大油的质量分数对脱油率的影响;当微波辐射功率为247.0 W/(60 mL)、脱油温度为90.4℃、油的质量分数为5.0%时,根据拟合公式得到静置30 min乳化液的脱油率达到最大22.21%。
By uniform design method, the influence of microwave irradiation power, de-oiling temperature and oil content on de-oiling rate of low oily emulsion were investigated. Furthermore, the corresponding experimental formula was fit with MATLAB programming. The fitting value agreed with experimental data perfectly. The results indicated that the de-oiling rate increased with microwave irradiation power meeting negative exponent law, and grew up with de-oiling temperature linearly, and decreased with oil content meeting parabolic relation. Moreover, the factors ofdeoiling temperature and oil content had interaction effect. Rising oil content reduced the effect of de-oiling temperature on de-oiling rate. In contrast, rising de-oiling temperature increased the effect ofoil content on de-oiling rate. According to the fitting formula, maximum de-oiling rate stewing 30 min reached 22.21%, when microwave irradiation power was 247.0 W/（60 mL）, de-oiling temperature was 90.4℃, and oil content was 5.0%.
