Development of a method and technology for obtaining vegetable oil from safflower seeds

The article is designed and engineered compact line for processing grain safflower, which used the equipment of the increased efficiency, implementing progressive processes with application of modern physical methods of treatment. This line includes bucket Elevator (Noria), a receiving hopper, the air-sieve separator, intermediate tank, Trier (osgoodby and qualitronic), stone-dividing machine and separator for separation of Caucalis lappula, screw conveyor, intermediate bunker, peeler, oil press machines, the device for the deposition of oil (the sump), pump, frame filter. The process of collapse in the grinding pilot plant, in which the destruction of the epithelial layer of the shell is due to the fact that the compression stress in the impact zone exceeds the limit of elastic deformation of the shell of the grain. Conducted sieve analysis, which was studied granulometric composition fed to the compression of the particles of safflower seed, in this case to characterize the granulometric composition of the raw material, consisting of particles of irregular shape, used the concept of equivalent diameter. As a result of the experiments was the dependence of the equivalent particle diameter from the diameter of the sieve. Since the degree of extraction of safflower seed are hugely influenced by the moisture source of the product, was therefore carried out experimental studies of compaction with different moisture content of the seeds, and with the addition of Luz-Ki. From the analysis of graphic dependences were established a range of optimum moisture safflower seed 8,5--10%, providing the lowest residual oil content and hence the greatest yield of oil. Also managed to significantly increase the efficiency of extraction of oil by adding safflower seed pre-milled husks, which allowed to obtain cake with a residual oil content of 12% when you multiply pre-pressing and to 6% at the final extraction
