Determination of drying characteristics and kinetics of bitter kola (garcinia kola) using page’s model

Single-layer drying characteristics and kinetics of garcinia kola was studied with slice thicknesses of 1mm, 3mm, 5mm and 7mm at temperatures 45oC, 55oC, 65oC and 75oC using natural convention laboratory oven . The results obtained revealed that garcinia kola slices dried in the falling rate period. Moisture ratio, characteristics drying rate constant, drying time, effective diffusivity and activation energy were significantly (
