Determination of agriculture grain dryer performance
Part 1. General
1 Scope
This section provides a method for the evaluation of continuous and batch-type grain dryer performance. This section provides a method for determining the dryer
Experimental tests under steady state conditions, the ability to obtain the required rate of water evaporation. This section also specifies the test
Performance (data) to the other input conditions and criteria under environmental conditions conversion method.
This section applies to the determination of continuous and batch-type grain dryer performance.
