Most buyers choose the wrong route because they don't know the market for their oil

Route comparison

Hot press vs cold press: the rapeseed decision matrix

Which route fits you

Choose the route before buying any equipment

1. Step 1

   1 · Know your seed

   What variety is locally available and at what price? Double-low now dominates most Chinese provinces; conventional or mustard seed is regional — confirm before committing.

2. Step 2

   2 · Know your buyer

   Bulk crude buyers, local bottled-oil market, and export specialty buyers each need a different oil character and quality documentation. The buyer decides the route more than anything else.

3. Step 3

   3 · Match the frame to the route

   Hot press → 300/325. Cold press → 355/400. Buying a 300 and later trying cold press accelerates frame wear and reduces cake quality permanently.

4. Step 4

   4 · Decide on cooking

   Hot press: steam cooker is mandatory and cannot be removed without losing 6-8 pp of yield. Cold press: remove the cooker from scope and upgrade the frame instead.

5. Step 5

   5 · Check crude destination acid value

   If crude must meet ≤3 mg KOH/g for refinery intake, confirm that cooking temperature holds for the entire run season, from startup to the last batch.

What to confirm before scoping Rapeseed Hot Press vs Cold Press

Rapeseed Hot Press vs Cold Press 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 Rapeseed / Canola 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

project scope 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.
