Stainless-Body Dual-Mode Screw Press
Stainless housing, cold and hot pressing, sized for walnut oil and small commercial runs.

Before you order
What to check on this machine
Three things worth settling on this particular model before money changes hands. They are the points that most often turn into a complaint after delivery.
- Which components are stainless where oil actually contacts them.
- Cold-press yield on walnut, which is lower than any hot-press figure.
- Cleaning schedule — nut oils oxidise fast in residue.
