Daily production capacity : prssing 80-100Ton , preprssing 180-240 Ton

Model YZY 290 preliminary oil press has two functions : pressing and prepressing , under the condition of normal pretreatment , main performance characteristics are as follows :

1. With a large handling capacity , the workshop covers an area of smaller , low power consumption , reasonable .

2. The cake structure prepressing loose but not scattered , in favour of to the solvent penetration.

3. The oil and water content in cake , and is suitable for solvent leaching . 

4. The barrel screw using light pressure ,regular pressure ,the pressure step by step and other advanced technology ,low residual oil in cake . 

5. The cake checking mechnism adopting the worm gear and worm patent technolo-gy ,no need to stop , easy and quick for calibration and adjustment .

6.Extracting cage has the design of ear plate opening and closing , easy to assembly and maintain , reduce labor intensity .

7. using labyrinth seal for the end face of pressing bolts , solve the problem of press-ing bolts junction surface and dregs seeping .

8. The qulity of pressed oil refining rate is high .

9. The machine qulity and the yield of extractor fit well .

10. Pressurize progressively , to reverse materail in a pressurized state , can effectively solve the problem like difficult to press of corn germ , dry coconut ,  rapeseed such oil plants .
