标准摘要
[中文适用范围]： ISO 11520 的这一部分规定了附加程序，并为测试和评估特定谷物作物（包括小麦、大麦、燕麦、玉米、水稻、高粱和油菜）的连续流式和间歇式谷物干燥机的干燥性能提供了指导。 它补充了 ISO 11520-1 中给出的一般程序，该程序基于仅干燥含水量在 20% 至 15% 湿基的有限范围内的小麦。 给出了以下方法和数据：a) 确定在稳态条件下干燥谷物时干燥机的蒸发率；b) 校正干燥机的主要性能特征，包括蒸发率、谷物流量、干燥时间以及单位能量和燃料消耗，参考和其他环境条件。 规定了对输入和输出谷物进行采样以评估谷物质量变化的程序。 [外文原描述]： This part of ISO 11520 specifies additional procedures and gives guidance for testing and evaluating the drying performance 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 wheat over the limited range of moisture content of 20 % to 15 % wet basis. Methods and data are given for a) determining the evaporation rate of driers when drying grain crops under steady state conditions, and b) correcting the main drier performance characteristics, including evaporation rate, grain flow rate, drying time and 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.
