花生油 · Peanut Oil Press route selection and product-market fit
Decide which process route is actually being offered before the discussion narrows to tonnage and machine options.
Peanut route = feed form (pods vs kernels) × moisture (5-8%) × aflatoxin control (<20 μg/kg) × temperature (hot 80-100°C vs cold ≤60°C) × press class (300-325 vs 355-500) × filtration (200-300 mesh vs 1-5 μm) × cake value (feed vs flour).
Hot-press production route
Roast 160-180°C → 300-325 ton press at 80-100°C → yield 40-48% → residual oil 6-8% → 200-300 mesh filtration → bulk edible oil. Best for throughput and operating stability. Smoke point 230°C after refining.
Cold-press premium route
≤60°C → 355-500 ton press → yield 35-42% → residual oil 8-10% → 1-5 μm bag filter → 250-500 ml dark glass. Best for premium bottled brand. Smoke point ~160°C unrefined; label as salad/drizzle oil.
Phased or mixed route
Start with hot-press bulk line (300-325 ton). Add cold-press premium line (355-500 ton) + bottling after market proves demand. Share shelling and cleaning; separate pressing and filtration.
How hot press, cold press, and product positioning connect
The route is not a label; it comes from roasting, filtration, crude-oil finish, and market positioning together.
How regional edible oil and premium bottled oil split the story
When the project starts asking about finish quality and retail positioning, route planning should carry the downstream handoff too.
Product lanes
Commercial routes this seed commonly serves
Peanut route = feed form (pods vs kernels) × moisture (5-8%) × aflatoxin control (<20 μg/kg) × temperature (hot 80-100°C vs cold ≤60°C) × press class (300-325 vs 355-500) × filtration (200-300 mesh vs 1-5 μm) × cake value (feed vs flour).
Thermal-oil roaster and hot-press control
Hot pressing needs roaster capacity, heating method, and discharge rhythm defined before press sizing.
Both hot and low-temp routes need post-press handling
Route choice affects filtration, settling, storage, and cake handling, not only press class.

Decision factors
Questions that change the route decision
- Will the oil be sold as bulk edible oil (hot), filtered workshop oil, or premium bottled cold-pressed peanut oil?
- Does the raw material stay clean, dry (moisture 5-8%), and aflatoxin-free (<20 μg/kg) enough for a premium cold route?
- Is cake value (protein 45-50%) important enough to influence roast temperature and pressing strategy?
- Will the project remain press-only, or is wider line expansion (bottling, flour, export) already likely after startup?
What to avoid
When route selection gets oversimplified
- Do not choose cold pressing only because it sounds premium. It needs ≤60°C discipline, clean kernels, 1-5 μm filtration, and dark-glass bottling.
- Do not describe a hot route vaguely. Roast 160-180°C, press 80-100°C, and 200-300 mesh filtration should be written as clearly as the press model.
- Do not compare routes without saying where the crude oil goes: bulk tank, refining, or bottling line.
- Do not treat route choice as isolated from cake economics. Cake protein 45-50% can add 20-30% revenue if managed.
