Why Choose a Hydraulic Oil Press for Peanut Oil?
The hydraulic oil press machine uses a slow and uniform hydraulic pressing process, which is superior to mechanical screw pressing in terms of oil yield, oil quality and machine lifespan.
Key advantages of hydraulic oil pressing:
- Oil yield up to 55%
- Residual oil as low as 6–8%
- Stable hydraulic system ensures long-term reliability
- No chemical solvents, 100% physical pressing
- Suitable for both hot pressing and cold pressing
As you can see from the picture above, the hydraulic oil press model 325 which has 325 tons down pressure ability is suitable for peanut/groundnut.The pressed cake can be very solid, which means the residual oil rate is very low.
Compared with traditional screw oil presses and mechanical oil presses, the hydraulic oil press machine offers several advantages for peanut oil production:
- Higher and more stable pressing pressure: The hydraulic system provides consistent pressure throughout the pressing process, ensuring optimal oil extraction from peanuts.
- Lower residual oil content in peanut cake: The high pressure exerted by the hydraulic oil press results in a drier peanut cake with minimal oil content, maximizing oil yield.
- More suitable for high-value edible oil production: The gentle pressing action of the hydraulic oil press helps maintain the nutritional integrity of the peanut oil, making it ideal for premium edible oil products.

Overview of peanut pressing process using Hydraulic Oil Press
- Crush peanuts into powder with a crusher machine(pre-press machine)
- Roast the peanut powder in a flat-bottomed wok to enhance aroma and oil yield
- Feed the roasted peanut powder into the hydraulic oil press barrel
- Press the oil out of the peanut powder
- Collect the peanut oil and filter it using a pneumatic filter press for clarity and purity.
- Collect the pressed peanut cake for further processing or use, such as pulverizing for additional oil extraction or as animal feed.
- The pressed cake can be further processed using a Cake Pulverizer machine to achieve higher oil extraction rates or can be used as animal feed directly.
- Store the filtered peanut oil in clean, food-grade containers for distribution or further refining if necessary.
- Configure suitable filling equipment according to the production demand, and fill the peanut oil into the bottle.
