Oil production of nuts and/or seeds with a screw press have different rules than other food production such as meat, milk or juice. Nut and seed oil is anti-corrosive because it contains hardly any water. In contrast, milk contains about 87% water. In dairy production, there is no wear material from pipes or silo tanks. However, in an oil press, there is more friction and wear from machine parts. With stainless steel, the press screw will wear and release the chromium and nickel (found in stainless steel) which are toxic to humans. Therefore, the press and parts in a screw oil press should be made of hardened steel, not stainless steel.
NUTS AND SEEDS ONLY. THE PITEBA DOES NOT WORK WITH OLIVES. I do sell a kit now that works with most olives!
The Piteba Manual Nut and Seed Oil Press is the original design made in Holland with quality parts, and food safety in mind. The Piteba is still made by the small family owned company that came up with the original design. There is at least one illegal copy out there that is made in Asia where food safety, quality and employee treatment are of little concern. This is a great unit. Any concerns about its quality please check my feedback. I have sold 1000s of these over the last 5 years and only have very happy customers.
We've used our Piteba MANY times to press macadamia nuts and sesame seeds. It works great. We've sold some to friends of ours as well and they've successfully oiled hemp seeds, kukui nuts, coconuts and sunflower seeds. Its a great item for people who want fresh, raw nut and seed oils but don't want to pay the extremely high price for it. The Piteba would also be great for soap makers who want to make their own oils.
There are many videos on YouTube showing it in use.
The press does not come with the top hopper or a container to catch the oil. The Piteba is made to to shipped anywhere in the world with low shipping costs. It comes with everything else pictured. The hopper is made by cutting the top off a plastic pop or water bottle. A small jar is used to catch the oil.
Item will be shipped via USPS Priority Mail medium flat rate box. We are only charging actual shipping cost. If you would like insurance, please let me know so we can get you a price.
The Piteba must be mounted to a counter or work surface. You can also mount it to a board and then clamp the board to a counter using a woodworking clamp.

Processing Details
Important for a good result: the seed should be well dried (8% humidity)! In case the press cake is squeezed through the oil slit: the seed is not dry enough. Seed Expelling Instructions (rpm=rounds per minute)
Type of Seed | Expelling Properties | Remarks |
Almond | Well dried, whole almonds with seed coat are expelled. Bridge formation may occur in the funnel. It might be easier to feed the expeller without a funnel. Turn crank at 55-60 rpm. |
|
Babassu (Orbignya phalerata) |
The kernels need to be reduced in size by grating, pounding or chipping. Turn crank at 45-50 rpm to allow oil to flow to the oil outlet. |
|
Beechnut (Fagus sylvatica) |
Well dried seed with 8% moisture or less should be expelled including the seed coat. Remove first any sand, stone and twigs. Bridge formation may occur in the funnel. Use a small wooden stick to ease flow of seed. Turn at 50-60 rpm. |
|
Cocoa Bean | Whole beans can be processed, including skin. Flaked beans will be easier to fill which will increase yield. Oil clarifies after about 24 hours at 50° C and will solidify after cooling. Turn crank at 50 rpm. |
|
Coconut (coprah) |
Well dried coprah is reduced in size by cutting, grating or grinding. Feeding the expeller requires some skill due to bridge formation. To avoid oil clogging of the screw turn calmly at 45 rpm to allow oil to flow to the oil slit. |
|
Hazelnut | Remove (deshell) the nuts. To increase output per hour reduce the size of the kernels (seeds) by coarsely grinding or grating. Turn at 50 rpm. |
|
Hemp Seed (Cannabis) | The seed runs easily into the press cage. Turn at 45 rpm. |
|
Jatropha (physic nut or Jatropha curcas) |
The seeds should be removed from the capsules. The whole seed should be expelled. Remove any stones and sand by sifting. Avoid bridge formation in the funnel by using a small wooden stick. Turn at 50 rpm. |
|
Linseed | The seed runs easily into the press cage. Turn at 45-50 rpm to allow the oil to flow to the oil slit. Clean the oil slit regularly. |
|
Niger Seed | The seed runs easily into the press cage. Turn at 45-50 rpm to allow the oil to flow to the oil slit. Clean oil slit regularly. |
|
Oil Palm Kernel | The kernels are very hard. The kernels are first reduced in size in a hammer mill as used for maize. Prevent bridge formation in the funnel with a small wooden stick. Keep the oil warm to allow settling of dirt before decanting. |
|
Peanut (groundnut, unroasted and deshelled) |
Well dried groundnuts are expelled with the thin brown seed coat. Prevent bridge formation of the seed in the funnel. Remove any stones and gravel. Clean oil slit regularly. Turn at 45 rpm. |
|
Pumpkin Seed | Expel with the seed coat. Remove stones and gravel to avoid damage to the expeller screw. Seeds enter slowly into expeller leading to a relatively low oil yield per hour. Turn at 55 rpm. |
|
Rapeseed | First remove any sand with a fine sieve and straw with a coarse sieve. Seed has to be very well dried until 6-8% moisture content. Extraction efficiency is highly reduced above 8% moisture content. Turn at 45 rpm to allow oil to flow to the oil slit. |
|
Safflower | Seed should be expelled with its seed coat. Remove any stones and gravel. Prevent bridge formation of the seed in the funnel with a small wooden stick. Turn at 45-50 rpm. |
|
Sesame Seed (sim sim) |
The seed must be dry with only 4-5% moisture content. Turn the crank slowly at 45 rpm to allow oil flow to the oil slit. Clean oil slit regularly. |
|
Soya Bean | Take care and remove any sand, stones and straw before expelling. Seeds flow easily in the expeller. Beans should be preheated in a pan before expelling. Turn crank at about 50 rpm. |
|
Sunflower Seed | The whole seed (undecorticated) should be expelled. Take care to remove any stones before expelling; prevent bridge formation in the funnel with a small wooden stick. Turn at 60 rpm. |
|
Walnut | Remove the shell. Grind kernels coarsely including the partition skin between the 2 halves. Turn at 55-60 rpm. |
