1.Screw thread
The screw thread is made of Cr12 die steel.Cr12 die steel has a high resistance to abrasion,which can prolong the service life of the machine.
And our screw thread adopts three-grade press,which can press the materials completely.
2.Grooves for material rotation
There is groove in both side of each screw row.It can make sure that the material can rotate in the press cage.
And it also can make the material pressed fully.
With grooves on the screw row,5% oil yield can be improved.
3.Screw rows
The space between screw rows is very small,which can make sure that the materials can be pressed completely.
This can improve oil yield.
4.The pressing part (cold oil press machine)
It’s the press part of the machine.There is no heating part in it.
So our machine is used for pure cold press.And the materials don’t need to be fried.
5.The vacuum filters
All of our oil press machine are equipped with vacuum filters.It can make sure the high purity of the pressed oil.
The oil filters filtrate the oil because the vacuum pump can form the negative pressure between the inside and the outside of the filter tank.
6.The cake outlet
When use cold press,the material need to be pressed twice to reach the ideal oil yield.
The first pressed oil cake came out from the cake outlet.
And the materials come down from the feed inlet.
The mixture of the oil cake and the materials are delivered in the machine to press through screw conveyor.
7.The inner part of control system
Our oil press machine has the feature of easy operation.
After preliminary test,the machine can operate once the start button is pushed.
