Brief Introduction of DLZ Single Screw Oil Press
1st. Application and Characteristics
The machine is suitable for extracting oil from materials with high oil content. Preprocessing of oil material should be made before its being processed.
The main Characteristics
The rationale of the machine is an innovation compared with previous ones and it operates steady with reasonable structures and brilliant mechanical performances. The main transmission is composed of some important components, such as extracting screws of superior alloy steel with strict heat processing. The durability is perfect, for the estimated longevity is more than 10 months.
Screw cages and the main shaft adopts double order squeeze with large compression ratio and length-radius ratio. Either makes it the machine to run in a great pressing performance or it promises a great propelling force along the axial direction. Thus it is hard for oil material to slide within the machine barrel. In addition, the pressing strip with special polygon makes an outstanding contribution to the highest efficiency of pressing oil.
2nd. Main Structure
The Structure of DLZ15.0 for pressing oil from sesame is illustrated by the following graph below. It is composed of power system, feeding system, pressing screw system, pressing cage system, oil outlet system, oil cake outlet system, base support, bearing system, thrust bearing assembly as well as cooling system.
3rd, Rationale and the main parameters
Switching on motor, then power and motion will be transmitted directly to screw shaft. The oil material in the hopper will be move downward by the gravity to the inlet of screw transmission after the feeding panel has been opened. Hence oil material will be propelled forward by components, including pressing screws, pressing rings and scrapers. During the process, the oil material will continually be pressed while the oil is flowing out. Finally, less and less oil has been left behind in the cells and the chunk will be formed after it is coming out of the oil cake outlet.
