    Abstract: An indirect solar dryer was tested for drying sheanut kernels. 
  The influence of tray distance from heat source, airspeed and particle size 
  on drying kinetics was investigated. Optimum drying air parameters obtained 
  in the dryer were airspeeds of 1 and 1.4 m sec<SUP>-1</SUP> and a temperature 
  of 40-45&deg;C. Sheanut kernel slices dried entirely in the falling rate period. 
  Drying rate decreased with increase in particle size. The effect of particle 
  size on the drying rate suggested that the drying process was controlled by 
  internal mass transfer. Drying kinetics was modeled with characteristic drying 
  curve and diffusive models. Effective moisture diffusivities of sheanut kernel 
  slices calculated without shrinkage were greater than those calculated with 
  the incorporation of shrinkage by a value of about 50%. Acid and peroxide values 
  indicated that butter from the dryer could be classified either as category 
  1 or 2 irrespective of the drying conditions to which the kernels were subjected.
