Specific heat capacity of lentil seeds by differential scanning calorimetry



Specific heat capacity of lentil seeds by differential scanning calorimetry



Transactions of the ASAE 34(2): 517-522



Differential scanning calorimetry (DSC) was used to determine the specific heat of lentil seed. Accurate measurement with this method requires a good seal condition of the sample pan and relatively thin sample specimen. The value of specific heat of lentil seeds ranged from 0.81 to 2.2 kJ/kgK. Specific heat increased quadratically with moisture content over the range from 2.1% to 25.8% (w.b.) and linearly with temperature varying from 10 degrees C to 80 degrees C. The classical compartment model was modified to accommodate the variation of specific heat with temperature and mositure content.
