Optimization of oil extraction process by the method of mathematical modeling

Abstract

The main objective of the experimental study of all processes is the analysis, study and generalization of all available results. In accordance with the idea of indexing search experiment was carried out in several stages. The number of stages and steps on each of which depended on the results of the previous stage and the ultimate goal of research. The ultimate goal of the study is to determine the optimum process conditions. Studies vegetable oil extraction process was conducted in a pilot plant set up on the basis of a single-screw Oil-presses. To ensure maximum efficiency Oil-presses without loss of quality of the finished necessary to ensure continuity and uniformity of oilseeds admission hopper. To process the experimental studies, the software complex STATISTICA 10 was applied. To obtain the regression equation, the matrix data was processed using the MS Excel software package. It is found that in order to provide the required performance Oil-presses need to set the angular speed of the screw in the range of 5.5–6.4 s-1, the value of the annular gap between the screw and curb chamber is 0.7–0.9 mm, the quantity gap curb camera of 0.16–0.18 mm. To optimize the process, the output values of the parameters converted into a dimensionless scale desirability d. In the course of the research found that the desirability of the D function, which characterizes the adequacy of the obtained values, has an extreme experience in the 8 and equal to 0.8. On the basis of the following parameters should be considered optimal obtained data: the angular speed of the screw of 6.6 to 1, the value of the annular gap between the screw and camera curb 0.92 mm, the magnitude of the gap.
