Abstract
The aim of this study was to develop and test an oilseed expression machine for oil production. The tested parameters were: (1) Machine setting of one stage and double stage expression (2) Screw speeds of 30, 50, 70 and 90 rpm (3) Cake output clearance 0.5, 0.8, 1.1 and 1.4 mm (4) for double stage expression setting intermediate choke gap of 0.6, 0.8, 1.0 and 1.2 mm. and (5) Moisture content of oilseed 6 %, 8% and 10%.
Results obtained increasing in expression efficiency by: reducing the choke gap, reducing the screw rotational speed, increasing seeds moisture-content to 8% (d.b),and using double stage machine.
Maximum oil expression efficiency was 86% at 0.5 mm choke gap, 30 rpm screw rotational speed, 6% moisture content and two stage machine setting with 0.6 mm intermediate choke gap. On the other hand, minimum oil expression efficiency was 52% at 1.4 mm choke gap, 90 rpm screw rotational speed, 6% moisture content and single stage machine.
The evaluated parameters affecting the expression process, oil productivity, expression efficiency, expressed oil temperature, oil production cost are discussed in the paper.
