How does your oil press work?

The seed is placed into the feeder either by labor or by conveyor. Then through the huge pressure or violent motion in the closed press, the original structure of oil seeds will be broken and a series of changes happened inside. Finally the oil is expressed out of the seeds.

What can I do with the crushed oil cakes?

Oil cake residues still contain crude nutrition such as protein and fiber, so they are very good fertilizer or can be used as animal feed.

Do we need to buy a filter?

If you order our auto filter- integral oil press, then you don't have to buy oil filter as the automatic machine includes it.

Does the oil need to be filtered?

Generally, in our experience any solid matter in the oil settles out naturally within 2-3 days.

Do I need an oil pump to transfer oil away?

No, if the press is mounted on a platform, oil can flow by gravity into a tank.

How do I control the extraction rate of oil?

We recommend that the press be fitted with a speed controller so that the screw speed can also be adjusted- the condition of the meal is the best visual guide to the rate of extraction of oil. Generally if the cake is coming off in thin flakes -oil extraction is at an optimum.

What are the basic maintenance requirements for your oil press equipment?

Fill up all grease cups and oil holes with lubricants at least once every day. The lubricating oil in the speed reduction gear box must be filtered and changed in every regular overhaul.

If the oil residual is higher than the design, how to solve it?

Usually, please check the operation is follow the Manual or not. If yes, check the steam cooked flake is in good condition.

How to maintain the oil mill?

The bearings and the adjusting block of the oil press should be lubricated, and the screw and rings should be inspected every week. Gearbox should be changed every 6 months.

Do I need to de-hull my Soy, Sunflower or Safflower seed?

No, it is not necessary. As the oil is expelled from the meat the hull gets expelled into the meal creating high quality meal with no try sin inhibitors. You can extrude the seed strait from the combine, and as a rule of thumb, if it’s clean enough to plant, it’s clean enough to extrude. So, as an example, if you have some 5 year old seed sitting around, (which you wouldn’t plant), you wouldn’t want to run it through the press either… it’s too dry at this point or you won’t get much out of it.
