The ZYL346 twin-screw oil press machine is the ideal processing equipment for vegetable oil mills.
Like conventional screw oil expellers, it utilizes screw compression and shearing to achieve optimal oil extraction through seed fragmentation.
Moreover, this oil press accommodates various pressing temperatures, enabling high-temperature, optimal-temperature, and low-temperature oil extraction processes.

It is widely applicable for pressing vegetable oils from soybeans, rapeseed, cottonseed, sunflower seeds, peanuts, corn germ, tea seeds, and other oilseeds.
Performance Features
1. Low Investment. Eliminates the need for a roller mill and steaming/roasting pot, significantly reducing the financial burden on oil mill operators.
2. Enhanced Durability. Features a higher strength safety factor; frame-type structure; resistant to deformation; extended service life.
3. Superior Quality. Produces oil with a lighter color and achieves a higher refined oil yield.
4. Multi-stage pressing. Achieves higher extraction rates and lower oil residue content in pomace, reducing costs.
5. Easy maintenance. Press cage features hinged ear plate opening/closing design; reduces labor intensity.
6. High output. Requires minimal workshop space and power consumption; features a rational and elegant appearance.
