Small oil expeller
Small oil expellers use a screw to compress prepared oilseeds and nuts, separating oil from press cake. Piteba documents manual and motorized small-scale examples; their settings and feed requirements do not define every press.

PITEBA electric oil press · Piteba oil expeller
The Piteba electric oil press uses a motor-driven screw to separate oil from prepared oil-rich seeds and nuts. Oil drains through a slit; pressed cake exits the cap.
A Dutch-made modern press with a Groningen inspiration
Piteba describes its oil press as a modern product inspired by traditional rapeseed presses used in the Groningen region in the early twentieth century and during the Second World War. The company says it has manufactured presses in-house in the Netherlands since 2005 and later added an electric version. That account identifies inspiration, not a direct surviving design lineage or an origin for all screw presses. Piteba reports delivery to more than 150 countries, a manufacturer statement about distribution rather than evidence that this particular configuration is used everywhere.

A screw press with a motorized drive
The electric Piteba is a named, current configuration of a compact screw oil press. Its motor and gearbox turn the same press mechanism as the hand-driven version. Prepared seeds or nuts enter through a hopper. Inside the cage, the screw compresses them; oil escapes through a narrow slit, while the more solid press cake leaves through the cap. An adjustment bolt changes the pressure at the outlet, and the correct setting depends on the material being pressed. The motor makes the operation continuous without hand cranking; Piteba lists a 0.37 kW motor on a 230 V / 50 Hz supply and reports throughput up to about 3.5 kg of material per hour, depending on seed type. Its listed weight is about 17 kg. These are specifications for the manufacturer's electric set, not a yield guarantee.

The seed determines the preparation
The machine is intended for oil-rich seeds and nuts; Piteba lists examples including sunflower, walnut, sesame, peanut and rapeseed, and limits its broad suitability claim to material with more than 25 percent oil. The maker's instructions call for seed moisture around 10 percent and emphasize removing grit and stones. Some materials need shelling, crushing or a slower feed; others enter the screw more readily. The adjustment bolt is therefore a working control, not a universal dial setting. Piteba publishes separate preparation notes and settings, and its own yield table distinguishes each seed rather than offering one output figure for the whole machine. The manufacturer's seed-specific table is useful as an operating reference for that press, but the numbers are not independent comparisons between presses.
Oil, cake and maintenance
The press produces two streams. Oil runs out through the cage slit; the compressed cake exits the cap. Piteba says the oil may look cloudy when first collected and can clarify after settling. The press separates oil from solids but does not refine the oil or determine how long it will keep. Its product page uses “cold-pressed” for oil it says remains below 40 °C during pressing; that is the manufacturer's stated specification, not evidence for its broader nutritional claims. Piteba also describes a small supplied burner for preheating the press before work in cooler conditions, not for use during pressing. The maker's cleaning instructions describe removing cake and seed remnants, cleaning the cap and press parts, and storing the press well oiled. Follow the instructions for the exact motor and any supplied accessories.
Secure mounting and moving parts
This is powered machinery, not a hand-operated mill. Piteba tells users to mount the press firmly, use the filling funnel so fingers cannot reach the screw, remain nearby if seed flow bridges in the hopper, and stop the motor with its switch rather than pulling the plug. The maker's hand-press manual explains that substantial force is required with some seeds; the electric configuration has a mounting base and motor and must follow its own instructions. If the optional preheating burner is supplied, Piteba says it is used before pressing and is off during pressing; follow the burner instructions. The sources do not establish one universal setting, seed preparation or throughput, and do not promise a health benefit or describe the nutrition of any particular oil.
History
Piteba states that it has manufactured presses in-house since 2005, later added an electric model, and drew inspiration from rapeseed presses used in Groningen around the early twentieth century and during the Second World War. This records the maker's account of inspiration, not an independently established direct lineage.
Equipment details
CapacityThe maker reports input throughput by mass per hour rather than a batch-vessel capacity.
SizeNo external dimensions are published on the inspected pages; the electric set is listed at approximately 17 kg.
PowerElectric Piteba lists 230 V / 50 Hz and a 0.37 kW motor for the electric set. A supplied burner may preheat the press before pressing in cool surroundings; the maker says it is not used during pressing.
How you get oneBought, manufactured Piteba states it has manufactured presses in-house since 2005 and sells the electric configuration directly and through dealers.
CarePiteba instructs users to remove cake and residual seed, clean the cap and press parts, and store the press well oiled. Follow the exact electric model and accessory instructions.
Made of
- Metal press frame, cage, screw and mounting base — Supports and contains the screw-press mechanism
These are visible in the manufacturer's product photograph and described as press parts in its manual; the company does not provide a full bill of materials. - Electric motor and gearbox — Turns the screw at a slow, continuous rate
Shown on the electric model and described by the maker; motor and gearbox are not features of the hand-operated version. - Feed hopper and adjustment cap — Feeds seeds and adjusts the press-cake outlet and pressure
The product page and manual describe a funnel or hopper and an adjustable press cap; exact forms differ by accessory and model.
Risks and precautions · Standard risk
Moving screw
The powered screw compresses material inside the press cage; the manufacturer warns that fingers must be kept away from it.
Hazard sourceElectrical motor
The electric model uses mains power and an overload protection switch.
Hazard sourceOptional preheating burner
Piteba says a supplied burner can preheat the press before pressing when the surroundings are cool; the flame is not used during pressing.
Hazard sourceUse the supplied filling funnel and keep hands away from the moving screw; stay near the machine while seeds are feeding.
Control sourceUse the motor's on/off switch rather than disconnecting the power cord to stop it.
Control sourceSecure the press on a stable mounting surface. If using the supplied preheating burner, follow the maker's burner instructions and do not use it while pressing.
Control sourceThe manufacturer specifies a 230 V / 50 Hz supply for this electric model; other supply variants are not established by the inspected pages.
Limits
The maker's stated throughput is up to about 3.5 kg per hour and varies by seed or nut; it is not a guarantee for every substrate.

Electric oil press. how to press oil from seeds and nutsThe electric version uses the same screw-press mechanism as the hand-operated version, driven by a slow motor and gearbox.
The company lists a 230 V / 50 Hz supply, a 0.37 kW motor, approximately 17 kg weight and throughput up to about 3.5 kg per hour depending on the seed or nut.
The screw compresses oil-rich seeds and nuts; oil exits through an oil slit and press cake through the cap.
Piteba lists oil-containing seeds and nuts above 25% oil, including sunflower, walnut, sesame, peanut and rapeseed; it specifies about 10% moisture and seed-specific preparation.
The product page says oil is cloudy at first and clears after settling; its claims that vitamins, enzymes and nutrients are preserved are not adopted.
The manufacturer warns to use the filling funnel, keep the press attended in case seeds bridge, and use the on/off switch rather than unplugging the motor.
The product photograph shows a red upright frame, black hopper, side-mounted motor and gearbox, and metal base; it is a product-specific example.
