摘要

摘要: 干燥是农产品安全贮藏的重要手段。热风干燥具有成本低、效率高、可持续大量干燥等优点,在农产品干燥中应用十分广泛。农产品热风干燥过程包含复杂的传热传质过程,对该过程进行准确预测可为绿色节能提质增效的干燥工艺开发、设备研制等提供重要理论依据。本文综述了农产品热风干燥传热传质过程的三种常用的数值模拟方法,即干燥动力学模型方法、连续介质假设模型方法和孔道网络模型方法。简要回顾这三种方法的发展历程,重点介绍其基本理论及数学模型,阐述其在农产品热风干燥研究中的应用,总结其优缺点,并对其未来发展进行展望。

Abstract: Drying is an important means of agricultural products during storage processing. Hot air drying is widely used in industry because of its low cost, high efficiency, sustainable mass drying and so on. The hot air drying involves complex heat and mass transfer process which is closely related to the development of green and energy-saving drying process and equipment. In this paper, three kinds of numerical simulation methods of heat and mass transfer in hot air drying are reviewed, namely, drying dynamics model, continuum hypothesis model and pore network model. The basic theories and research status of the numerical simulation methods, merits and demerits, and application of prospects in drying are summarized.
