Plan a peanut oil press line from feed preparation to oil and cake handling.
Confirm pods vs kernels, hot vs cold, aflatoxin and cake path first — then size on the factory line balance: pre-press ~500 kg/h → 5 woks → 5×325, or 355–500 cold.
State whether feed is in-shell pods, shelled kernels, or cleaned graded kernels — that decides shelling scope. Factory hot line: pre-press ~500 kg/h, 5 × electric flat-bottomed wok (~100 kg/batch), 5 × 325 presses (14 partitions, Ø390×800 mm barrel up to 100 kg, pure press 30–40 min, ~1.5 h for 2 barrels with loading), oil yield 45–55% on good kernels, residual oil 6–8%, system 60 MPa, motor 2.2 kW, cylinder 27SiMn. Cold premium uses 355–500 (370–630 ton), pure press ~2 h/barrel, ~4.5 h for 2 barrels. Filter with pneumatic multi-layer paper; keep aflatoxin B1 control and cake offtake in the same brief as model choice.
Factory hot line: pre-press ~500 kg/h → 5 × electric flat-bottomed wok (~100 kg each) → 5 × 325 presses (14 partitions, Ø390×800 mm, max 100 kg; practical feed often ~60 kg).
Hard data: pure press 30–40 min/barrel, ~1.5 h for 2 barrels with loading; oil yield 45–55% on good kernels; residual oil 6–8%; system 60 MPa, motor 2.2 kW, cylinder 27SiMn.
Cold premium: 355–500 series (370–630 ton), pure press ~2 h/barrel, ~4.5 h for 2 barrels. Pneumatic multi-layer paper filter after press; aflatoxin B1 control and cake path belong in the same brief as model choice.
Project path
Start the peanut project with feed, route, scope, and handoff
Before press tonnage is compared, confirm feed condition, route choice, current-phase scope, and the post-press handoff.
Thermal-oil roaster and hot-press temperature control
Use this roaster clip to check heating method, temperature control, and discharge rhythm before the press cycle is sized.
Watch roasting window
Path boardFeed, route, scope, and handoff in one board
Use one board to keep the project path clear before equipment selection starts.
Start with feed prepName the feed honestly: pods, shelled kernels, or graded kernels
If shelling stays inside this phase, the press discussion, roasting load, and workshop layout all change before machine comparison even starts.
Lock the route before arguing over press classes
A practical hot route usually belongs with wok or drum roasting language, while a premium lower-temperature route needs stronger kernel discipline and cleaner post-press handling.
Freeze what this purchase actually covers
Press only, press plus filtration, or a phase that already reserves ties into settling, storage, refining, or filling. That boundary changes both layout and quotation logic.
Define the crude-oil and cake handoff early
Pneumatic filtration, settling tanks, buffer tanks, cake collection, and downstream transfer should be included in the main project path instead of appearing as vague add-ons later.
Scope this phase
State where this phase stops before the quotation is built
Many peanut projects do not buy a whole line at once. They upgrade an existing workshop, add filtration, or prepare pipe and tank interfaces for a later refining or filling phase.
Press room as a standalone purchase
Useful when shelling or roasting already exists and the buyer mainly needs a stable loading rhythm plus a clear crude-oil handoff.
Pressing and filtration together
A stronger fit when the first phase must include cleaner crude oil, clearer sediment control, and a more usable handoff to tanks.
Reserve the downstream interface now
Even if storage, refining, or filling are deferred, the next interface should be described so the first quotation does not stay abstract.
- Hot-route projects are rarely just about the press. They are about roasting, batch packing, filter timing, and labor rhythm together.
- Upgrade projects need to say what equipment stays in service and what modules are new, instead of asking for a vague 'peanut oil machine.'
- If peanut cake has value, say so early. Cake collection, pulverizing, or storage should not wait until the third quotation revision.
- Separating current scope from future scope keeps the quotation boundary stable.
After pressing
Show where crude oil goes next, not just how oil comes out
A peanut project feels more credible when filtration, settling, storage, and cake flow appear beside the press instead of hiding inside a later FAQ.
Crude oil leaving the press into pneumatic filtration and settling tanks
This clip follows crude oil from press exit through pneumatic filtration, into settling tanks, and on to buffer storage. It also shows peanut cake collection and stacking. Seeing the actual handoff builds more project credibility than a process-flow diagram alone.
Watch post-press clip
Handoff mapFiltration, settling, storage, and cake flow map
One board keeps both crude oil and byproduct routing visible during scope review.
Review the handoff layoutFilter first, then move to tank
A better fit when appearance, sediment control, or a cleaner handoff to later refining already matter in phase one.
Settle first, then process further
Useful for workshops with existing tank assets, but only if the batch rhythm and holding logic are shown clearly.
Keep cake handling visible
If cake is sold, reused, or prepared for later processing, treat it like part of the main line logic instead of waste disappearing off screen.
- Show whether crude oil moves into pneumatic filtration, settling, buffer storage, or directly downstream instead of saying only that filtration is optional.
- Retail-facing peanut oil projects notice clarity and finish immediately, so post-press timing belongs much earlier in the project story.
- If refining or filling may come later, reserve the interface now; otherwise the future expansion starts with avoidable rework.
- Once post-press flow is written concretely, pressing, filtration, storage, and packaging can be quoted against the same scope.
RFQ pack
For a quotation that survives review, send these details together
A useful project packet brings together feed proof, scope proof, plant proof, and the intended handoff after pressing.
- State whether the feed is pods, shelled kernels, or graded kernels and attach one to three feed photos instead of writing only 'peanuts.'
- Give output targets by hour or shift and say whether the workshop runs one shift, two shifts, or in intermittent batches.
- Name the route, then list any existing wok roasters, drum roasters, filters, settling tanks, or storage tanks that stay in service.
- Add workshop dimensions, voltage, doorway or lifting constraints, and any photos that show how new equipment must enter the room.
- Explain where crude oil goes immediately after pressing and whether peanut cake is collected, stored, pulverized, sold, or reused.
- If this phase stops at the press room, include one note about the likely next phase so the quotation does not get reviewed in the wrong scope.
A useful project packet should make scope, layout, and delivery review possible without another round of vague follow-up.
Pressing scope & modules
Factory peanut hot line: pre-press ~500 kg/h → 5 × electric flat-bottomed wok (~100 kg each) → 5 × 325 hydraulic presses (14 partitions, Ø390×800 mm barrel, up to 100 kg crushed powder; practical feed often ~60 kg to save load time). Pure press 30-40 min/barrel; ~1.5 h for 2 barrels with loading. Oil yield 45-55% on good kernels; residual oil 6-8%. System 60 MPa, motor 2.2 kW, cylinder 27SiMn. Cold premium: 355-500 series (370-630 ton), pure press ~2 h/barrel, ~4.5 h for 2 barrels, residual oil target ~≤5% on solid cake (premium cold yield lower than hot). Pneumatic multi-layer paper filter after press; optional Filling Machine Series for bottling.
Hot-route workflow with real hard data
Roast 160-180°C → moisture to 3-5% → 300-325 ton hydraulic press at 80-100°C → 100 kg/barrel, 30-40 min → plate-frame filter 200-300 mesh → crude oil clarity target: sediment ≤0.1%, moisture ≤0.2%.
Press family matched to route temperature
Hot peanut lines: 300-325 ton, 80-100°C, higher throughput. Cold premium: 355-500 ton, ≤60°C, lower yield but premium positioning. Do not use cold-press claims for hot-route oil.
Batch references with real numbers
Standard barrel 390 mm × 800 mm loads ~100 kg. Model 325 uses 14 partitions. Hot cycle: 30-40 min/barrel. Cold cycle: 60-90 min/barrel. Residual oil hot 6-8%, cold 8-10%.
Aflatoxin control and food safety
Aflatoxin B1 limit <20 μg/kg (EU) / <20 ppb (US). Damaged/moldy kernels must be removed by color sorter or manual picking. Test every batch. One contaminated batch can destroy an entire export shipment.
Real equipment & workshop
See equipment, workshop, and delivery
Check peanut form and cleaning first
Before quoting, confirm whether the project starts from in-shell peanuts, kernels, or cleaned kernels ready for pressing.
See loading, press rhythm, and cake discharge
Use this scene to decide whether the phase is only the press or also roasting, transfer, oil receiving, and cake handling.
Decide settling, filtration, or storage after oil flow
Once oil flow is visible, filtration grade, tank size, storage method, and packing boundary become easier to define.
See the 300 / 325 / 355 barrel and model scale
Seeing the barrel, frame, and loading space makes capacity, shifts, and model selection easier to discuss.
Workshop view for layout and operating side
Useful for checking footprint, access aisles, loading side, cake discharge, and filtration position.
Cake discharge should be planned with oil handling
Bagging, bins, or crushing after discharge changes press-room flow and by-product value.
Common project questions
Align the common questions first
Yes. Shells are 30-40% of pod weight and contain no oil. Hydraulic pressing works only on shelled kernels. If you have pods, shelling must be in scope. Shelling also generates 30-40% by-product (shells) that need a disposal or sales plan.
