Acid value, color, moisture, and phospholipid load decide whether rapeseed crude oil can be sold as flavor oil, held in tanks, or sent to refining without extra cost.
Control rapeseed crude-oil acid value, color, phospholipids, degumming timing, filtration, and tank storage so the oil is ready for sale or refining.
Hot-pressed rapeseed oil often lands near 1-3 mg KOH/g acid value with a deeper color; record both so the buyer knows the starting point.
Rapeseed carries notable phospholipids, so hydratable gums must be planned for, not ignored.
Moisture and fines drive sediment in the tank and raise the refining and storage risk.
Use this page to define crude-oil quality before sale or refining.
Before deciding sale, storage, or refining, name the crude-oil condition in measurable terms instead of a vague 'good oil' claim.
Higher seed moisture, broken seed, and long storage push acid value up. Fresh, clean seed keeps it lower and easier to refine.
Hot pressing and stronger cooking give a deeper color; flavor markets may accept it, refining markets usually want it lighter.
Rapeseed gums are mostly hydratable, so water or acid degumming can remove a large share when timed well.
Moisture, fines, and meal carryover decide settling time and filter load before any tank decision.
Match filter type to endpoint: coarse for crude sale, finer and warm for refining feed or bottling.
Keep fresh crude, settled oil, and refining-feed oil in separate, labeled tanks so sampling stays clear.
Keep one labeled sample from each tank to trace acid value, color, and sediment after handoff.
Rapeseed Crude-Oil Quality Control Points 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.
When discussing Rapeseed Crude-Oil Quality Control Points, pin models to published factory specs — not tonnage alone.
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).
After Rapeseed Crude-Oil Quality Control Points 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.
Record feed form, daily volume, moisture, and sorting needs so pretreatment is not left to operators.
Traditional flavor oil may use light filtration; canola retail often needs full RBD. Cold dense powder needs 355–500 — not 300/325 alone.
Prepare space, power (often 380V/50Hz/3ph), labor, target package, local rules, and acceptance method before quotation.
