Profile:
 Model Z390 is a kind of large-scale continuous type screw oil expeller which is applied for prepress before solvent extraction or once press process of large-scale oil mill. It's suitable for processing of peanuts, cotton seeds, rape seeds, sunflower seeds, soya beans, castor-oil seeds, bran and other oil bearing plant with high oil content.
Characteristics:
This machine adopts advanced structure and material synchronous with international technology. It is with good appearance and meaning of main machine required by modern large-scale oil processing manufactory. It is with main characteristics under normal pretreatment condition as follows:
-    Large capacity with small installation area
-    Large compression rate, cakes with loose structure but less crushes and favorable for solvent extraction
-    Oil content and moisture of cakes is favorable for solvent extraction
-    Feeding with variable frequency control and less power consumption
-    Less residues return and purified oil quality, easy for refining
-    Easy and quick disassembling to reduce time of operation stoppage

Specifications:

*  model Z390 is used as pre-press. Model Z390(A)  is used as expeller.

**  the parameters mentioned above depend on the normal oil plant with complete oil materials pre-treatment equipment and necessary cooking processing at first. It may be changed in case of different quality of oil materials and operation conditions.
Technical condition before prepress: moisture 3.5%, temperature 110~120
Technical condition before once press: moisture 2.5%, temperature 115~130
* Husk content in kernel after dehulled : 10%
