Abstract: Extruder of vegetal oil formed by a system for the Oil and Flour Production from primary products, that works in a different way from the existing squeezers and known in the actual market. This extraction system, with this system of the present patent simplifies and improves the processes that use the actual equipments, and also saves the energy consumption by incrementing the yield of the obtained production when compared with the existing equipments. The former result is due to this system that works simultaneously the different processes in only one machine, what nowadays is made in a series of machines in each one of the different processes. In the actual systems several different processes are used, one for the oil extraction and others more for the transformation of sub-products until reach the final product; using different equipments in each case after the oil extraction.
