uncertainty of the estimate of specific total
energy consumption
Establishes methods for evaluating the drying performance of continuous flow and batch grain dryers. 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. Covers principle, symbols and units, test equipment, preparation for test, test procedure, calculation of results and correction to standard conditions. BS AMD 9836 RENUMBERS STANDARD
