Abstract Process intensification is commonly implemented in engineering practice to result in higher energy efficiency. In this study, the applicability of reaction engineering approach (REA) to model several process intensification schemes of drying is assessed. The REA was employed to model microwave, ultrasonic-assisted and infrared-heating drying. For microwave and infrared-heating drying, a new formulation of equilibrium activation energy was introduced. In all schemes, the relative activation energy, generated from one accurate convective drying run, was coupled with the equilibrium activation energy to yield the activation energy. Combined with the suitable heat balance, the REA is accurate to model these enhanced drying processes. Benchmarks against diffusion-based model showed that the REA yielded a closer agreement toward the experimental data. While the REA is accurate, the REA is very efficient in generating the drying parameters. The REA-based model is readily applied in industrial settings as a basis for fine-tuning the process to manufacture the products with the desirable quality.

利用微波、超声波和红外加热强化干燥果蔬的反应工程方法建模

摘要 工程实践中普遍采用过程集约化来提高能源效率。在这项研究中，评估了反应工程方法 (REA) 在模拟几种干燥过程强化方案的适用性。REA 被用来模拟微波、超声波辅助和红外线加热干燥。对于微波和红外加热干燥，引入了一种新的平衡活化能公式。在所有方案中，由一次精确的对流干燥运行产生的相对活化能与平衡活化能相结合以产生活化能。结合适当的热平衡，REA 可以准确地模拟这些增强的干燥过程。针对基于扩散的模型的基准测试表明，REA 对实验数据产生了更接近的一致性。虽然 REA 是准确的，但 REA 在生成干燥参数方面非常有效。基于 REA 的模型很容易在工业环境中应用，作为微调过程以制造具有理想质量的产品的基础。
