1.电流体动力学节能干燥技术及其应用研究 Study on Application of Electrohydrodynamic Drying and Related Energy Saving Technology 2.为了提高电流体动力学干燥速度，降低干燥能耗，并将其应用于水产品的干燥加工，本论文以物理学、食品科学、水产品加工学、静电技术、数值分析和统计学等学科的理论为基础，主要开展了以下五个方面的研究工作： In order to improve the drying rate and reduce the energy consumption of EHD drying, as well as, dry the aquatic products by EHD drying, Based on theories of Physics, Food Science, Aquatic Products Processing Science, Electrostatic, Biometrics and numerical analysis, there are five parts addressed in the thesis: 3.以豆腐为试验材料，通过对其进行电场预处理、不同电极下的电流体动力学干燥速度对比和电场下离子风屏蔽等实验明确了电流体动力学干燥机理。 A contrast experiments of drying rate on tofu using a needle electrode, a wire electrode and a plate electrode under different voltages have been evaluated in this study, respectively. At the same time, the contrast experiment of drying rate on tofu using needle electrode with glass enclosure and counterpart without it, as well as high electric field pretreatment. According to the experiment result, the mechanism of EHD drying was confirmed. 4.利用自制的电流体动力学干燥装置，通过改变干燥电压、电源极性、电极间距、针（线）间距等试验参数测定了它们对干燥速度与能耗的影响程度，确定了最佳干燥参数，即采用针电极正高压，在针间距和上下电极间距分别为8cm和9cm时能够获得较大的干燥速度并消耗相对较少的电能。 By changing the voltage, the voltage polarity, the electrode spacing and the distance between the two neighboring needles（wires）, the factors related to the drying rate and energy consumption were quantitatively studied. The results indicate that When the electrode spacing is 9 cm and the distance between the two neighboring needles is 8 cm, the drying rate is the highest while the energy consumption is relative least, 45 kV is the optimum value for drying voltage. |

1\ Study on Electrohydrodynamic energy-saving drying technology and its applications 2\ In order to improve the drying rate and reduce the energy consumption of EHD drying, as well as, dry the aquatic products by EHD drying. Based on the theories of physics, food Science, aquatic products processing science, electrostatic, biometrics and numerical analysis, there are five parts addressed in here. 3\ In this study, a contrast experiments of drying rate on tofu using a needle electrode, a wire electrode and a plate electrode under different voltages have been evaluated respectively. At the same time, the contrast experiment of drying rate on tofu using needle electrode with glass enclosure and counterpart without it, as well as high electric field pretreatment. The mechanism of EHD drying was confirmed by our experiments. 4\ The factors related to the drying rate and energy consumption were quantitatively studied by changing the voltage, the voltage polarity, the electrode spacing and the distance between the two neighboring needles（wires）.The results indicate that When the electrode spacing is 9 cm and the distance between the two neighboring needles is 8 cm, the drying rate is the highest while the energy consumption is relative least, 45 kV is the optimum value for drying voltage. |
