Oil press manufacturing: materials

[zedem19]

Hello,

I want to get started with the production of an oil press with a worm screw.

I have read that given the humidity present in the grain, the oil produced is particularly acidic.

What material (supporting acidity, pressure, abrasion of sand grains and metallic particles contained in the grain) do you recommend for the realization of the screw and the basket?

Goods.

At first sight, I would say stainless steel ...

if it is for edible oil, you will be able to do a DIY that will allow you to extract the oil from just about everything.
but if it is for carburetion, take a look at the oliomobile site, especially in forum and you will see that it is not won at all.

Even cooking oil is not that easy to obtain!
