Screw oil press working principle
YZS-120 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.
Main structure of screw oil making machine
It is composed of feeder, gearbox, pressing cage, screw shaft and machine stand etc.
How to extract Coconut oil?
To prepare for coconut oil extraction,first crack open fresh coconuts and remove the copra by carefully prying the
meat away from the shell with a knife. Cut the copra into 1/4 inch pieces. There is no need to remove the brown
outer lining, called the testa, on the coconut meat. Allow the copra to dry thoroughly to remove all moisture from
the meat. Now that the press in clean and ready to operate, put the dried copra into the hopper in the top of the oil
expeller, turn on the press and it will compress the copra to extract the oil. If you want purer oil, you can equip a
filter press or set up a small oil refining line to filterate your coconut oil.
Coconut/copra oil production
There are basically two different types of coconut oil: Virgin Coconut Oil (VCO) and RBD Oil.These two vary on
the methods used to produce them. RBD Oil is made from the dried copra while VCO is made from fresh coconut
meat. RBD Oil and VCO are processed and produced in a variety of ways that can affect its quality, appearance,and
flavor.
