BS 3986-2:1998

This standard BS 3986-2:1998 Methods of test for drying performance of agricultural grain dryers is classified in these ICS categories:

• 65.040.20 Buildings and installations for processing and storage of agricultural produce

This Part of BS 3986 specifies additional procedures and gives guidance for testing and evaluating the drying performance of continuous-flow and batch grain dryers for specific grain crops including wheat, barley, oats, maize, rice, sorghum and rape. It supplements the general procedures given in BS 3986 : Part 1 that are based on drying only wheat over a limited range of moisture content of 20 % to 15 % wet basis.

Methods and data are given for:

1. determining the evaporation rate of dryers when drying grain crops under steady state conditions; and
2. correcting the main dryer performance characteristics, including evaporation rate, grain flow rate, drying time and specific energy and fuel consumption, to reference and other ambient conditions.

Procedures are given for sampling input and output grain to assess changes in grain quality.

Gives additional procedures and requirements for commercial crops in addition to wheat over a wider range of conditions than that given in BS 3986:1991 now amended to become Part 1.
