Gce Model Questions Vol1 2021 Agricultural Science Question 19
Practice objective / multiple choice question 19 from the 2021 Gce Model Questions Vol1 Agricultural Science examination.
After harvesting, wheat grain has a moisture content of 18\% (wet basis). It must be dried to a final moisture content of 13\% for safe storage. The dryer operates at a temperature of 30\,°C, and the equilibrium moisture temperature is 20\,°C. The drying rate follows the linear model \(\Delta M = k (T - T_{eq}) t\) where \(k = 0.05\)\%\,h\^{-1}\,°C\^{-1}. Calculate the drying time required (in hours) to reach the desired moisture content.
