Abdou Shawky Abdou Al- Ashry;
Abstract
The main objective of this study was to modify and improve a small and simple expression machine for extraction oil by cold pressing from most common oilseeds. The developed machine was designed and constructed locally at the workshop of Agric. Engineering Research Institute, (A En IU).
The important results, which were obtained from this study can be summarized as follows:
The performance results of the modified expression machine is affected
by many factors as screw speed, outlet clearance, screw type and oilseed moisture content.
The meal oil content increased and the oil expression efficiency
decreased with increasing the screw speed from 30 to 50, 70 atld 90 rpm. The meal oil content increased arid oil expression efficiency decreased when increasing the outlet clearance from 0.4 mm to 0.8 111m and 1.2
111111.
The minimum value of feeding capacity was 50.9 and 50.7 kg/h for standard and tapered screw respectively at screw speed 30 r.p.m, 0.4 111111 outlet clearance and 12% oilseed moisture content.
The maximum value of feeding capacity was 102.57 and 101.47 kg/h for standard and tapered screw respectively at screw speed 90 r.p.m, 1.2 111 outlet clearance and 6.3% oilseed moisture content.
The maximum value of power requirement was 5.72 and 6J2 kW with
the use of standard and tapered screw respectively at screw speed 90 r.p.m., 0.4 mm outlet clearance and 12% oilseed moisture content.
The total costs of the machine were 3.73, 3.79 L.E/h for standard and tapered screw, respectively at the optimum conditions.
The meal oil content decreased and the expression efficiency increased with the increase of the oilseed moisture content from 6.3 to 9%. On the other hand, the increase of oilseed moisture content from 9.0 to 12.0% tended to increase the meal oil content and decrease the expression efficiency.
The tapered screw had given the lowest values of meal oil content and
the highest values of expression efficiency compared with the standard screw.
