Peanut Oil Pressing Solution

Quick Answer

Yes — the Haonuo hydraulic oil press is built for peanuts (groundnuts). Expect 40-48% yield (hot press, roasted kernels) or 38-44% (cold press) from shelled kernels, with residual oil in cake at 6-8% — against 10-12% for conventional drilled-barrel presses. One HN325 tabung press takes 100 kg per batch (30-60 min hot press), so a single machine runs roughly 800-1,200 kg/day; a double-barrel or HN365 reaches 1,500-2,500 kg/day. Always shell first: pressing unshelled peanuts cuts yield by 15-25%.

Peanut Oil Press Overview

Groundnut (peanut) oil is the everyday cooking oil of West Africa — Nigeria is one of the world’s largest groundnut producers — and demand is equally strong in India, China and Southeast Asia. A hydraulic peanut oil press machine lets small and mid-sized mills press aromatic hot-pressed oil or premium cold-pressed oil directly from shelled kernels, for local markets or export buyers.

Haonuo’s peanut pressing solution is built around hydraulic press technology. Unlike screw expellers, which generate friction heat that can scorch the oil, a hydraulic groundnut oil extraction machine applies static, controlled pressure. The oil stays below scorching temperature, the natural peanut flavor is preserved, and residual oil in the cake typically lands at 6-8% (Haonuo factory tests with graded peanut and sesame at 6-8% moisture; results vary with seed variety and preparation) — against roughly 10-12% for a conventional drilled-barrel press.

Every Haonuo hydraulic press handles both routes on one machine: cold pressing for premium, nutrient-rich oil, and hot pressing after roasting for a stronger aroma and 3-5% more oil per batch. The difference is entirely in seed preparation, which is exactly why the seven-step process below matters.

Peanut Oil Yield Expectations

*The oil-content figure for unshelled peanuts is diluted by the shell mass; shells also absorb oil during pressing, which is why shelling is mandatory.

Key factors affecting yield:

• Shelling — pressing unshelled peanuts cuts oil yield by 15-25% and darkens the oil.
• Variety — high-oil varieties (Virginia, Spanish) outperform runner types.
• Moisture — kernels entering the tabung press should be at 4-6% for hot press, 6-7% for cold press.
• Roasting — conditioning at around 130°C (120-150°C) develops the nutty aroma and lifts yield by 3-5%.
• Tabung Press design — the bar-type slotted tabung press drains oil over a far larger area than a drilled tabung press, typically extracting 2-3% more oil per batch.

What you get from 100 kg of shelled peanuts

Typical figures for well-shelled, properly conditioned peanuts at standard machine settings; based on Haonuo factory tests with graded peanut at 6-8% moisture, actual results vary with variety, moisture and cycle settings. Liters assume oil density of about 0.92 kg/L.

Why Choose Our Peanut Oil Press

• Hydraulic, not screw — static pressure keeps the oil below scorching temperature; no burnt taste, and 6-8% residual oil instead of 10-12%.
• One machine, two products — switch between premium cold-pressed and aromatic hot-pressed peanut oil by changing preparation only.
• Complete line from one supplier — shelling and preparation advice, roaster, press and filter matched as one balanced line.
• Factory-direct, built for your site — FOB Qingdao pricing, payment terms confirmed on the proforma invoice, free voltage customization (415 V/50 Hz, 380 V/60 Hz or your local standard), standard models ready in 15-25 working days.
• Tested before it ships — every press runs under full working pressure and is checked for leaks before packing, with English manual, online video guidance and stocked spare parts.

What 100 kg of Shelled Peanuts Is Worth

At 800-1,200 kg/day, one HN325 turns shelled peanuts into roughly $600-1,800 of product per day. In Nigeria, retail groundnut oil has recently traded around ₦2,500-4,500 per litre depending on region and season.
