BS 3986-1:1998

This standard BS 3986-1:1998 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 describes general procedures for evaluating the drying performance of continuous-flow and batch grain dryers and specific procedures for rewetted wheat over a moisture content range of 20 % to 15 % wet basis. The methods specified are for determining the evaporation rate which the machines concerned are able to achieve when drying wheat under the steady state conditions prevailing during the tests. Methods for correcting observed performance to other input and standard ambient conditions are described.

NOTE 1. BS 3986 : Part 2 specifies additional procedures and requirements for testing and evaluating dryer performance for other crops, including barley, oats, maize, rice, sorghum and rape, and for wheat over a wider range of conditions than those specified in Part 1.

NOTE 2. The titles of the publications referred to in this standard are listed on the inside back cover.

Methods for evaluating continuous flow and batch grain dryers, correcting results to standard conditions and estimating the uncertainty of the predictions. Does not cover on-floor dryers. Covers specific procedures for rewetted wheat over a moisture content of 20% to 15% wet basis.
