Method for obtaining vegetable oil from safflower seeds

Abstract

This utility model relates to the oil and fat industry, specifically to methods for processing oilseed plant materials, and can be used in the production of safflower oil from pre-hulled safflower (Carthamus tinctorius L.). The technical result of this utility model is an increase in safflower oil yield, a reduction in the energy consumption of the pressing process, a decrease in the residual oil content in the cake, and an improvement in the quality of the resulting oil. A method for extracting vegetable oil from safflower seeds involves hulling the seeds to a 60-85% shell separation rate, pneumatically separating the kernel and shell with an air stream, crushing the separated kernel to a particle size of 1-3 mm, and pressing at an adjustable pressing unit gap of 3-9 mm, a pressure of 7-20 MPa, and a screw rotation speed of 5.2-8.2 rad / s. This utility model increases the yield and improves the quality of safflower oil.
