Crude oil quality

Crude-oil settling and clarification should define the filtration order

Post-press handling needs its own scope instead of repeating the press. Filter-first or settle-first, buffer tank or storage tank, direct downstream handoff, and cake discharge direction all affect layout and quotation scope.

Layout choices

Three common post-press handoff arrangements

Press outlet to filtration

Moves particle and appearance control forward, but filter capacity must match the press batch rhythm.

Settling tank before filtration

Fits existing tank assets or slower clarification, but tank volume, valves, and cleaning space must be reserved.

Filtered oil to storage or downstream

Fits later refining, filling, or sales storage when pipe interfaces and pumping method are reserved now.

Quotation data

Post-press information customers should send early

  • Whether crude oil is sold as crude oil, used internally, refined later, or prepared for bottled sales.
  • Any retained filters, settling tanks, storage tanks, pumps, or pipe routes already on site.
  • Whether filtration and storage handoff are judged by hour, shift, or daily batch.
  • Whether filters and tanks can stand near the press or must be placed in a separate zone.
  • Whether cake receiving, stacking, crushing, or outward transport crosses the oil route.

The earlier this section is clarified, the easier it is to align press, filter, tank, and workshop movement in one scope.

What to confirm before scoping Peanut Crude-Oil Settling, Clarification, and Filtration Handoff

Peanut Crude-Oil Settling, Clarification, and Filtration Handoff should not be quoted from an equipment name alone. Check feed lots, target oil, post-press handling, and packing rhythm in one scope before deciding which Peanut Oil Press modules stay. Listed on the factory hot-press page — discuss 300/325 first.

When feed condition, moisture, impurities, batch weight, and product position are unclear, press tonnage and filter area become guesswork. Factory systems share 60 MPa and 2.2 kW motors; hot pure press is 30–40 min/barrel and cold pure press is ~2 h/barrel — cycle time matters more than brochure tonnage.

  • Confirm whether feed is whole seed, kernels, pretreated material, or an existing semi-finished stream.
  • Confirm whether the target is crude oil, filtered oil, bottled oil, drum ingredient oil, or a refining handoff.
  • Hot cycle reference: pure press 30-40 min/barrel, ~1.5 h for 2 barrels with loading; cold pure press ~2 h/barrel, ~4.5 h for 2 barrels.
  • Confirm batch rhythm, labor, changeover, retained samples, power (often 380V/50Hz/3ph), and site install conditions.

Factory model check

Match hot / cold models to factory hard data

Pin models to published factory specs before tonnage talk.

Hot 300/325: 300–325 ton, 60 MPa system, standard barrel Ø390×800 mm / max 100 kg, pure press 30–40 min/barrel, ~1.5 h for 2 barrels with loading, 2.2 kW motor. Cold 355/400/426/480/500: 370–630 ton, integrated frame, same 100 kg standard barrel, pure press ~2 h/barrel, ~4.5 h for 2 barrels with loading; optional Ø300 high-pressure barrel max 60 kg. Residual oil target ~≤5% (peanut hot often 6–8% measured).

  • Standard barrel Ø390×800 mm, max ~100 kg crushed feed; optional Ø300 high-pressure barrel max ~60 kg.
  • Cylinder material 27SiMn; cold frames are integrated molded steel; hot frames are typically H-type channel steel.

Equipment check

Quality needs to land in equipment interfaces

Once the route is clear, write the interfaces: how preparation feeds the press, how oil leaves the press, how filtration connects to tanks, and how packing receives finished oil.

Front-end input

Record feed form, daily volume, moisture, and sorting needs so pretreatment is not left to operators.

Filtration, tanks, and peanut cake

Define pneumatic/plate-frame filtration, tanks, retained samples, and cake offtake before press count. Factory hot lines often use multi-layer paper filters.

Delivery data

Prepare space, power (often 380V/50Hz/3ph), labor, target package, local rules, and acceptance method before quotation.

Questions on this page

Does peanut oil always need filtration?

If the oil is only held internally, settling may come first. If it is sold, stored, or prepared for bottling, filtration, settling, and storage order should be defined clearly.

Why discuss cake on a filtration page?

Oil and cake both leave the press area. If cake is collected, crushed, stored, or moved out, it uses space and can cross the oil-side workflow.
