Drying Kinetics And Phytochemical Evaluation Of Picralima Nitida
ABSTRACT
The drying kinetics Picralima Nitida
was conducted at Emery laboratory using an oven dryer at different drying
temperature of 50 °C 60 °C, and 70 °C and with a microwave oven at different
microwave powers (1000w, 670w, 330w). Fick's second law was used to calculate
the moisture diffusivity and it was observed from the result that moisture
diffusivity increases with increase drying temperature or microwave power. The
drying characteristics of Picralima Nitida were satisfactorily described by
logarithmic model. The drying rate Picralima Nitida decreases with decrease in
moisture content. The estimated diffusivity constant and activation energy was
estimated at 3.708 x 10 6 rn2/s and 27.797KJ/mol, 3.01 x 10 9 m2/s and
94.636w/g respectively for the oven drying and microwave drying. The effective
diffusivity for the oven drying and microwave drying processes were found to
range between 1.194 x 10'° m2s'- 2.19 x 1010 rn2s and 2.41 x -- 1.57 x i0 rn2s
respectively.
