Flaxseed quote guide: cold-chain spec, not just press tonnage

Six required fields

What turns an inquiry into a fast flaxseed proposal

• Seed lot: harvest date, storage history (≤15°C cool/dark?), oil 35-45%, FFA, peroxide. Old or warm-stored seed disqualifies premium positioning.
• Press temperature limit: ≤40°C (premium retail, peroxide <3 at bottling) or ≤50°C (mainstream cold-pressed, peroxide <5).
• Press class + cadence: 200 ton (<500 kg/month) or 355 ton (500-3000 kg/month), pressing 1-2 days/week aligned to sales.
• Post-press chain: 1-5 μm bag filter (N₂-purged), 200-1000 L jacketed tank ≤15°C + N₂ blanket O₂ <2%, ≤14-day hold.
• Packaging: 100-250 ml dark amber/violet glass, inline N₂ flush, cap torque 8-12 lb-in, refrigerated logistics for premium.
• Compliance + cake: organic / non-GMO / FDA / EFSA + cake plan (feed / SDG nutraceutical extraction).

Site data

Attachments that prevent rework

• Workshop drawing: m² × ceiling, drainage, fire exits. Cold-storage room location for tank and finished bottles.
• Utility readings: 380V/50Hz available kW (40-80 kW for 200-355 ton press), water (jacket cooling), N₂ supply (cylinder bank or generator).
• Existing equipment: press, filter housing, storage tank, bottling line — capacity, age, condition.
• Seed COA: oil content, moisture, FFA, peroxide, lignan, harvest date, lot number.
• Brand positioning: premium nutritional retail, ingredient supply, contract pressing — drives temp spec and cold-chain investment.

Project boundary

What to confirm before scoping Flaxseed Quote Guide | Seed Lot, ≤40-50°C Spec, N₂ Storage, Dark Glass, Cold Chain

Flaxseed Quote Guide | Seed Lot, ≤40-50°C Spec, N₂ Storage, Dark Glass, Cold Chain 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 Flaxseed Oil Press modules stay. Factory cold-press page lists this oilseed — prioritize 355–500 (370–630 ton), pure press ~2 h/barrel.

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

When discussing Flaxseed Quote Guide | Seed Lot, ≤40-50°C Spec, N₂ Storage, Dark Glass, Cold Chain, 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).

• 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.
• Factory cold-press page lists this oilseed — prioritize 355–500 (370–630 ton), pure press ~2 h/barrel.

Equipment check

project scope needs to land in equipment interfaces

After Flaxseed Quote Guide | Seed Lot, ≤40-50°C Spec, N₂ Storage, Dark Glass, Cold Chain 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.
