Agricultural grain driers - Determination of drying performance - Part 2 : additional procedures and crop-specific requirements

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.

Agricultural grain driers - Determination of drying performance - Part 2 : additional procedures and crop-specific requirements

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.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
