2.  The Introduction of the walnut oil press equipment:

The simple processing of oil pretreatment includes pressing, high temperature pressing, cold pressing (less than 70 degrees) etc.
?  Formal oil pressing can adopt one time or twice pressing of oilseeds. It is applicable for low capacity required oil processing oil plant. 
?  High capacity oilseeds pretreatment and oil pressing equipped with oil extraction treatment, is used in high capacity and large-scale oil pressing plant, or high oil content oilseeds processing plant. 
?  Oil prepressing can get up 70% oil fat of embryo, and residual oil inside pre-pressed cake can be extracted by organic solvent.

3.  The feature of the walnut press equipment

?  automatic institution can reduce operator's working intensity
?  large capacity and workshop area occupied small size and power consuption,management and maintenance are reduced
?  structure of pressed cake loose but not crushed which helpful for solvent penetration
?  oil rate and water of pressed cake suitable for solvent leaching
