In the article it is presented the analysis of constructive solutions of screw presses that are used for different types of oilseeds. An analysis of the characteristics and using of press equipment in different countries of the world has shown that the principles of action and workflow are the same. Application of oily presses in the conditions of farms with small volumes of oilseeds processing indicates a number of shortcomings, which include the low production of oil in one pass, increased time that spent on cleaning the press from clogging, which contributes to a significant decrease in productivity of the machine and the need for manual pushing pulp from bunker in the receiving and preparing chamber during repeated compression. There are indicated the theoretical aspects of the pressing process, the main technological parameters that influence on the intensity of the separation of oil from the pulp, which include: the speed of the screw shaft, the degree of seizing of the pulp by the first turn, the physical and mechanical properties of the pulp and the degree of wear of the surface of the screw turns. Investigation of these parameters and including into the industrial production of press equipment the results of research will eliminate the problem points according to the application in the technological process of oil production.

Key words: oilseeds, screw shaft, parameters of work, pulp, oil screw press.
