为改善油水混合油炸机工作过程中能耗高的问题,利用CFD软件建立油炸机模型.通过模拟油炸机升温过程与实物实验相结合的方式定性的获得油炸机油、水的温度分布.根据其温度分布调整油炸机的工作方式、改进其结构定量的分析其节能的效果.CFD模拟分析了模型中9个关键点的温度变化,得出油炸机各层温度相差明显,且每层温度分布均匀,有利于油炸加工.实验过程采集了部分关键点的温度值与仿真值对比,结果油炸层的温度差最大为5°C,过渡层为4°C,水层为3°C,仿真结果与试验数据一致.对比了两种加热管的加热效果,结果发现采用优化后加热管不仅能提高加热速度,还降低了过渡层和水层的温度,有效减轻了油炸机散热装置的负荷,节约了电能.“,”At present, the energy consumption of the oil-water mixture frying machine is very high. Researchers analyze its thermal conductivity process with theoretical calculation and on-line monitoring to reduce its energy consumption. But it is time consuming and expensive. The modern software CFD is used to build the model of the frying machine, and by means of the method that is a kind of combination of simulation and experiment to get the temperature distribution of oil and water. According to the temperature distribution, it can improve its working way and structure to save energy. The results show that the temperature distribution is not only homogeneous but also significantly different in each layer, which is advantageous to the fried processing. Some key points of the temperature value are collected and compared with the simulation results, the result shows that the maximum temperature difference of the fried layer is 5℃, the transition layer is 4℃, and the water layer is 3℃. It points out that the simulation results are consistent with the experimental data. The heating effects of the semicircular heating tube and the circular heating tube are compared, and it is concluded that the semicircular heating tube can not only increase the heating rate, but also reduce the load of the radiator in the fryer effectively.
