《GB/T 21163.2-2007农业谷物干燥机 干燥性能的测定 第2部分:附加测定规程和特定谷物要求》由TC201（全国农业机械标准化技术委员会）归口，主管部门为中国机械工业联合会。
本部分规定了连续式谷物干燥机和批式谷物干燥机对特定谷物，包括小麦、大麦、燕麦、玉米、水稻、高粱和油菜等的干燥性能测试与评价的附加规程和操作指南。

Scope

This part specifies additional procedures and operating guidelines for continuous grain dryers and batch grain dryers for the drying performance test and evaluation of specific grains, including wheat, barley, oats, corn, rice, sorghum and rapeseed. This part is a supplement to the general method of GB/T 21163.1. The general method is to use dry wheat as the basic raw material, and limit the moisture content range of its wet basis to 20% to 15%. The purpose of specifying methods and parameters is to: a) Determine the moisture evaporation rate under the condition that the grain dryer is in a steady dry state. b) With reference to standards and other environmental factors, the main performance parameters of the corrected dryer include water evaporation rate, grain flow rate, drying time and unit energy consumption and fuel consumption. The procedure also describes the method of sampling incoming and outgoing material in order to evaluate changes in grain quality.
