What is BS 3986-2 - Drying performance of agricultural grain dryers about?
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:
- Determining the evaporation rate of dryers when drying grain crops under steady-state conditions
- 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
BS 3986-2 provides for sampling input and output grain to assess changes in gran quality.
Who is BS 3986-2 - Drying performance of agricultural grain dryers for?
BS 3986-2 on Drying performance of agricultural grain dryers applies to:
- Manufacturers of agricultural grain dryers
- Dealers and importers of agricultural grain dryers
- Testing houses and labs for agricultural machinery
- Quality assurance services
- Regulatory bodies
- Agricultural Storage facilities
Why should you use BS 3986-2 - Drying performance of agricultural grain dryers?
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:
- A greater range in input and output moisture contents
- Other crops as well as wheat
- The impracticality of rewetting (dampening) some grains and of differing thermal characteristics.
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.
