Prediction of pressure and energy requirement of Jatropha curcas L bulk seeds under non-linear pressing

Popis výsledku v původním jazyce

This article presents the theoretical evaluation of pressure and energy requirement of screw press FL 200 (Farmet Model, Czech Republic) for oil processing of Jatropha curcas L. bulk oilseeds. Both the linear and nonlinear compression information were analysed. The tangent curve mathematical model was applied which is appropriate for fitting of linear experimental data as the dependency between compressive force and deformation in relation to bulk seeds pressing height and vessel diameter. The integral of the tangent model represents energy. The non-linear pressing involving a mechanical screw press FL 200 geometric parameters namely screw shaft diameter (mm), inner and outer diameters (mm), screw thickness (mm) and screw pitch diameter (mm) were incorporated into the tangent curve mathematical model. The press designed with 44 lamellas at the oil outlet were divided into seven pressing sections or chambers. The determined amounts of pressure and energy substantially increased along the pressing sect
