Physical properties of snake gourd seed (Trichosantes cucumerina L) relevant in grading and seperation CIGR Journal
Idowu, David Oluwafemi; Owolarafe, O.K..
The physical properties of snake gourd (Trancosanties cucumerina L) seed have been evaluated as a function of moisture contents,6.80%, 8.60%, 12.00%, 14.00% and 17.00% (db) moisture contents.  The properties investigated include one thousand mass, dimensions (length, width and thickness), sphericity, volume, true density and bulk density.  The results of the experiment showed that seed length increased from 11.30±0.3 to 12.4±0.50 mm, width (from 5.60±0.30 to 6.60± 0.30 mm), thickness (from 2.0±0.25 to 2.7±0.32 mm), one thousand mass (from 110.0±5.2 to 240.0±6.5 g), geometric mean diameter (from 5.02 ± 0.61 to 6.05±0.52 mm), sphericity (from 0.44±0.05 to 0.49±0.06), volume (from 38.98±4.1to 69.68±5.2 mm3), true density (from 0.91±0.26 to 0.97±0.30) and bulk...

Mathematical modelling of the performance of an impact snake gourd (Trichosanthes cucumerina. L) seed sheller CIGR Journal
Idowu, David Oluwafemi; Owolarafe, Oseni Kehinde.
A mathematical model for the prediction of shelling efficiency of an impact snake gourd seed decorticator was presented using dimension analysis based on the Buckingham’s pi theorem.  Experimental verification of the models was conducted comparing the theoretical predictions with estimates from the representation of conventional methods.  A high coefficient of determination was found between the predicted and the experimental value (98.45% for effect of moisture content on decortication efficiency; 99.69% for effect of hammer diameter on decortications efficiency and 97.35% for effect of hammer speed on the decortications efficiency) showing that the model is appropriate.
