Separation of oil and suspended solids from peanut slurry are two important interdependent operations in wet rendering of peanuts. A 3‐way centrifuge cannot be used efficiently for the separation of the different phases due to the large volume of fibrous suspended solids in peanut slurry. Removal of suspended solids from the slurry by filtration is too slow and incomplete, as the fine particles tend to block the screen. The alternative method of centrifugal sedimentation of the suspended solids causes emulsification of the oil and results in the inefficient separation of the oil. It is shown in the paper that efficiency of the separation of oil and carbohydrate fraction from peanut by wet rendering method depends on careful conditioning of the seed.
