Abstract
Recently, the demand for safflower products has been growing from year to year, which includes an increase in acreage and the popularity of safflower oil among consumers. In this article, based on scientific research, a screw press for the production of safflower oil was considered. The method of regulating the pressure difference of pressing by means of gaps between the screw and the core cylinder is given. A mathematical and nomogram model is proposed, which gives qualitative and quantitative characteristics of the press. As the literature reviews of studies conducted in the modern world and the Republic of Kazakhstan have shown, we will focus on the differences and features of the press, including of a fundamental nature from modern analogues of screw equipment. In any industry, the screw device is a unique working tool of wide application, since it simultaneously and continuously performs several functions. Therefore, the mathematical nature of the screw device, including the pressing screw device, is so complex that in all works in the literary review, due to their target features, they are limited to individual solutions. A feature of the work is not only mathematical, but also nomogram modeling, which allows you to choose the optimal pressure difference and productivity, taking into account the geometric design of the press screw and the seed cylinder and the structural and mechanical properties of raw materials.
