DETERMINATION OF THE RATIONAL PARAMETERS OF PRESSING PUMPKIN SEEDS BY METHODS OF EXPERIMENT PLANNING
Abstract
The article describes the process of pumpkin oilseeds crushing in a screw oil press using the method of planning a full-factor experiment. Mathematical methods of experiment planning were used in order to study the interaction of various factors affecting the process of oil extraction from pumpkin seeds. Pumpkin seeds (oil content 32-36%) were used as an object of the research. The article presents the results of an experimental study of the process of obtaining oil from pumpkin seeds in a screw oil press using CO2-extraction. A statistical analysis of the experimental results, a statistical and mathematical model of the oil extraction process was carried out, and rational parameters of the influencing factors were determined. For the study, central compositional rotatable uniform planning was applied and a full factorial experiment was selected.
