摘　　要：为提高固体农业物料生产加工设备的作业效率和加工质量,减少固体农业物料在收获后加工、贮藏与运输等环节的损失,农业工程领域学者对固体农业物料流变特性的研究越来越广泛。对流变学理论在果蔬、谷物、油料和饲草料等固体农业物料生产加工中的应用研究现状进行总结和探讨,指出流变学在固体农业物料加工领域存在物料材料被简化、经典模型拟合误差大、微观层面缺乏深入研究、局部力学特性难表达等问题,提出流变学经典模型修正方法研究需要加强、物料流变特性需要与微观特性相结合、流变学理论需要同现代计算机辅助技术相结合等建议,以期为固体农业物料加工工艺的优化和设备的研发提供新的思路。In order to improve the operating efficiency and processing quality of solid agricultural materials processing equipment,and reduce the loss of solid agricultural materials in the processing,storage,and transportation after harvest,scholars in the field of agricultural engineering have increasingly studied the rheological properties of solid agricultural materials.This article summarized and analyzed the application research status of rheology theory in the production and processing of solid agricultural materials such as fruits and vegetables,grains,oil and forage.It was pointed out that rheology has some problems in the field of solid agricultural materials processing,such as simplified materials,large fitting error of classical models,lack of in-depth research at the micro level,and difficult expression of local mechanical properties.It was proposed that the research on the modification method of classical rheological model needs to be strengthened,the rheological properties of materials need to be combined with micro properties,and the rheological theory needs to be combined with modern computer-aided technology for analysis.This will provide new ideas for the optimization of processing technology of solid agricultural materials and the research and development of equipment.
