Screw oil press working principle
YZS-95 screw oil press is an advanced oil making machinery that is capable of processing multiple plant seeds
and has better results to press soybean and cotton seeds. This oil expeller utilizes the screw shaft that is set-up
with different styles of screws and rotates when machine is running to push the material into chamber. Then the
oil is separated out through the extrusion of pressing worm and pressing ring. This oil press can cut the oil cake
into small pieces, which matches the needs of the expelling for times.

How to extract Peanut/Groundnut oil?
Peanuts/groundnuts should firstly be shelled and cleaned by certain seed cleaning equipments,to separate foreign
material (primarily soil, vines, stems, and leaves) from peanuts seeds.Then crushing and roasting the cleaned seeds
to proper particles as well as pressing temperature. At this time, the pretreated peanuts kernels could be pressed by
oil expellers to extract peanut oil. However,the crude peanut oil usually contains a number of impurities.So for edible
oil, the pressed peanut oil needs to be sent to the oil refining plant for further processing or you can just equip a oil
filter press to filterate your oil.
Methods of Peanut Oil Extraction
Oil from peanuts is conventionally extracted by either mechanical pressing or solvent extraction.Mechanial pressing
is a less efficient process but with heathier oil, leading to low oil recovery(40-60). Solvent extraction, although its
recovery is in the 90-98% range, has inherent disadvantages of poor quanlity of protein in oil cake(meal), and high
investment, and energy requirements. Both methods have their advantages and disadvantages, you can choose one
according to your oil making needs!
