本标准规定了粮食干燥机性能试验方法和生产试验方法。本标准适用于连续式粮食干燥机和批式循环粮食干燥机。
本部分规定了评价连续式和批式谷物干燥机干燥性能的方法。本部分规定的方法用于确定干燥机在持续稳定的试验状态条件下进行的试验能否获得所要求的水分蒸发速率。本部分还规定了将测试的性能(数据)向其他输入条件和标准环境条件下折算的方法。 本部分适用于连续式和批式谷物干燥机干燥性能的测定。
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、高梁和油菜等的干燥性能测试与评价的附加规程和操作指南。本部分是GB/T 21163.1一般方法的补充。其一般方法是以干燥小麦为基本原料的,且限定其湿基含水率范围为20%~l5%。 规定方法和参数的目的是: a) 测定谷物干燥机处于稳定干燥状态条件下的水分蒸发速率。 b) 参考标准和其他环境因素,修正干燥机的主要性能参数包括水分蒸发速率、谷物流量、干燥时间和单位耗能量和燃料消耗量。规程还对进出料的取样方法进行了说明,以便评价谷物品质的变化。
本标准规定了谷物干燥机大气污染物排放的术语和定义、基本要求、排放限值和测试方法。本标准适用于燃煤及稻壳等生物质颗粒(或压块)为燃料的谷物干燥机生产作业时排放的大气污染物管理。
本标准规定了谷物干燥机(以下简称“干燥机”)质量调查的术语和定义、调查对象、调查内容、用户调查方法、评价方法和调查报告的编制。本标准适用于对在用循环式干燥机和连续式干燥机的质量调查。其他型式干燥机的质量调查可参照执行。
本标准规定了批式循环谷物干燥机的术语和定义、型号及主要参数、技术要求、安全要求、试验方法、检验规则、标志、包装、运输及贮存。本标准适用于批式循环谷物干燥机(以下简称干燥机)。
This part of ISO 11520 describes methods for evaluating the drying performance of continuous flow and batch grain driers. The methods specified are for determining the evaporation rate which the machines concerned are able to achieve under the steady-state conditions prevailing during the tests. Methods for correcting observed performance to other input and standard ambient conditions are described.
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.\nMethods and data are given for\na) determining the evaporation rate of driers when drying grain crops under steady state conditions, and\nb) 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.\nProcedures are specified for sampling input and output grain to assess changes in grain quality.
This Standard specifies requirements for mechanical grain drier.
This Standard specifies the methods of test for heated-air mechanical grain dryer to determine the following performance characteristics.
