The Analysis Of Twin-screw Extruder On Parameters Of Pressing Screw And Pressure Of Oilseeds In Pressing Cage

With the development of the society, consumption in the oil is increasing significantlyImportant source of edible oil is coming from the supply of plant. So how can be moreefficient to make vegetable oil is becoming more important. Using the spiral oil presspressing oilseeds is a major way to make vegetable oil. Single screw oil press and doublescrew oil press are commonly used. Because of the advantages of the continuity workingprocess, high compression ratio and oil yield, so double screw oil press is getting muchattention.Making vegetable oil by pressing oilseeds is a complex process. From the perspective ofprocess. The article will analysis the impact that device itself make on squeezing processesand squeezing performance. When the equipment is working, press value in the presschamber is a very important parameter, the law of press will affect the whole press process.Combined with the existing problems and the existing research, the paper will put a keyattention to press in the press chamber, Mainly analyze influences that parameters of structurehave on oilseed pressure in the press chamber,.Combined with existing advanced methods, this paper will establish oil-seed solid model,when filling coefficient is1. Through model simplification, analyze flow field of model,research the changing rule of the pressure in the chamber under the condition of single screwelement. By analyzing the structure of pressing chamber, analyze influences that parametersof structure have on oilseed pressure in the press chamber. Combined with the project data,establish pressure model in the chamber, Point out affections that temperature、porosity、compression ratio have on the pressure, Which provides a theoretical guidance to laterresearch and new product design.
