Abstract
Abstract
Repetitive loading test of bulk palm kernels (unroasted) was conducted to determine the percentage kernel oil yield and energy demand using the universal compression testing machine (UCTM) of the maximum load of 200 kN and speed of 5 mm min−1. Pressing vessels of varying diameters (60, 80 and 100 mm) with a plunger were used together with the UCTM. The bulk palm kernels initial height of 60 mm was repeatedly compressed until permanent deformation was reached. The total amounts of mass of kernel oil leakage, deformation, percentage kernel oil and energy were measured/calculated. The main part of the study will be done using the mechanical screw press Farmer 20 - duo (Farmer 20, Farmet a.s., Ceska Skalice, Czech Republic) to determine the optimum processing conditions for achieving maximum kernel yield and specific energy requirement.
