BS 3986-2 is a standard that serves technical specifications for evaluating the drying performance of agricultural grain dryers, enabling the removal of moisture to prevent the deterioration and spoilage of grains in agricultural applications.
BS 3986-2 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.
BS 3986-2 supplements the general procedures given in BS 3986-1 that are based on drying only wheat over a limited range of moisture content of 20% to 15% wet basis.
BS 3986-2 provides methods and data for:
BS 3986-2 provides for sampling input and output grain to assess changes in gran quality.
BS 3986-2 on Drying performance of agricultural grain dryers applies to:
Grain dryers are machines used to dry agricultural goods such as wheat to remove moisture content and safe storage. Grain drying with a dryer allows for increased flexibility and productivity. Many tonnes of product can be dried in a few hours, whereas the conventional method would take several days.
The methods specified in BS 3986-2 takes into account the following factors:
BS 3986-2 provides users guidance on a test method for evaluating the drying performance of continuous-flow and batch grain dryers for specific grain dryers. BS 3986-2 also provides users with a step-by-step procedure for the method, enabling users to do the method correctly.
BS 3986-2 provides users guidance on scope, references, definitions, symbols, units, test procedure, grain quality, methods of correction of test results, guide to dryer residence times, minimum moisture removals and more, enabling the accurate evaluation of drying performance of agricultural grain dryers.
With obedience and compliance to BS 3986-2, users can develop and assess agricultural grain dryers, enabling optimised ambient conditions for safe storage and reducing spoilage risk for wheat in agricultural applications.
