| Abstract | Drying characteristics of peanuts in forced air oven at
40°C,60°C and 80°C ; batch type rotary drier at 110°C,130°C and
1 50° C were investigated .Moisture removal could be represented by
simple exponential mod el. Tempering improved the quality of peanut
dried by conduction heating.
The effect of convection and conduction drying was related
with the quality parameters s u c has breakage; shriveled;
weight/seed ; extra large kernels; flavor and germination . Experiments results revealed that peanut dried in forced air oven
was superior than peanut dried in batch type rotary drier.
In this present study , a rotary conduction drier using sand
as heating media was designed and developed. The peanut was moved
inside t he drier by continuous helical fins and mixed with heated
sand . Drying time was reduced by increasing the rotation
speed. Feasibility of drying high moisture peanut using conduction
heating with and without sand was investigated. Results showed
conducti on drying using sand as heating media increased t e
drying rate and quality of peanut than conduction drying using
batch type rotary drier. |
