标准范围

ISO 11520的本部分规定了额外的程序,并给出了测试和评估干燥过程的指南用于特定谷物作物(包括小麦、大麦、燕麦、玉米、,大米、高粱和油菜。它补充了ISO 11520-1中给出的仅干燥小麦的一般程序在含水量为20%至15%湿基的有限范围内。给出了计算方法和数据a) 在稳态条件下干燥谷物作物时,确定干燥器的蒸发率,以及b) 修正干燥器的主要性能特征,包括蒸发率、谷物流量、干燥时间以及参考和其他环境条件下的比能耗和燃油消耗。规定了对输入和输出谷物进行取样的程序,以评估谷物质量的变化。

This part of ISO 11520 specifies additional procedures and gives guidance for testing and evaluating the dryingperformance of continuous-flow and batch grain driers for specific grain crops including wheat, barley, oats, maize,rice, sorghum and rape. It supplements the general procedures given in ISO 11520-1 based on drying only wheatover the limited range of moisture content of 20 % to 15 % wet basis.Methods and data are given fora) determining the evaporation rate of driers when drying grain crops under steady state conditions, andb) correcting the main drier performance characteristics, including evaporation rate, grain flow rate, drying timeand specific energy and fuel consumption, to reference and other ambient conditions.Procedures are specified for sampling input and output grain to assess changes in grain quality.
