Feed prep

First identify whether the feed is pods, shelled kernels, or press-ready cleaned kernels

The feed-start question has to be answered first. In-shell peanuts cannot be quoted like press-ready kernels; shelled kernels still need checks for shell chips, broken kernels, damaged kernels, moisture, and grading stability.

Feed start

Three peanut entries create three different project scopes

  1. Step 1

    Pod entry

    Include or clearly exclude shelling, hull removal, cleaning, dust control, and kernel buffering in the quotation boundary.

  2. Step 2

    Shelled-kernel entry

    Attach photos that show shell chips, sand, broken kernels, damaged kernels, and whether second cleaning is needed.

  3. Step 3

    Clean-kernel entry

    Move the decision toward kernel grade, moisture control, feeding method, hot pressing, or lower-temperature pressing.

  4. Step 4

    Mixed feed entry

    If pods and purchased kernels both appear, design prep and buffering around the less stable feed path.

Project data

Clear feed photos are more useful than asking for a model first

  • Pod photos should show shell ratio, impurity level, dust, and whether centralized shelling is required.
  • Kernel photos should show shell chips, broken kernels, damaged kernels, mold risk, and grading consistency.
  • State whether feed arrives in bags, bulk, or bins, and whether daily supply is continuous or batch-based.
  • If shellers or graders already exist, send equipment photos, capacity, and discharge position.
  • Connect feed grade to the intended hot-aroma route or lower-temperature route before asking for final scope.

What to confirm before scoping Peanut Shelling, Cleaning, and Kernel Grading Before Pressing

Peanut Shelling, Cleaning, and Kernel Grading Before Pressing 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.
  • Listed on the factory hot-press page — discuss 300/325 first.

Equipment check

Preparation 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

Can in-shell peanuts be quoted as only a press?

Only as a rough direction. A formal scope needs to say whether shelling and cleaning belong in this phase because that changes prep equipment, roasting load, filtration, and layout.

Do shelled kernels still need cleaning?

Often yes. Shell chips, broken kernels, damaged kernels, and unstable moisture should be checked before the line counts as press-ready.

Send pods or kernels before asking for a roaster

Feed photos, shelling status, kernel grading, and impurity notes make the scope much clearer.
