Record feed form, daily volume, moisture, and sorting needs so pretreatment is not left to operators.
Flaxseed oil's 6-12 month shelf life makes pressing cadence a quality lever. Press only what sells in 3-4 months. Reference scale: 200-355 ton hydraulic, 80-100 kg/barrel, 60-90 min/cycle, yield 28-35% = 22-35 kg oil/cycle. Daily 4-8 cycles = 100-280 kg oil/day. Cake: 50-70 kg/cycle × protein 30-35% + lignans (SDG) 0.7-1.5% — defat + extract → premium nutraceutical lignan ingredient (5-10× cake feed price).

Small-Batch Flaxseed | 200-355 Ton, Yield 28-35%, Lignan Cake 0.7-1.5% SDG 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.
Factory model check
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).
Equipment check
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.

ALA oxidizes fast: closed filtration, N₂ tanks (O₂ <2%), dark glass 100–250 ml, plan batches for ~3–6 months refrigerated shelf life.
Prepare space, power (often 380V/50Hz/3ph), labor, target package, local rules, and acceptance method before quotation.
Flaxseed oil shelf life starts the day it leaves the press. Pressing daily but selling weekly creates 7-30 day in-tank holds with rising peroxide. Pressing 1-2 days/week aligned to sales velocity keeps in-tank hold below 7 days, peroxide <5 meq O₂/kg at bottling, and best-before date as long as possible. Better quality, lower waste.
Yes for premium projects. Cake from cold press has 8-12% residual oil + 30-35% protein + 0.7-1.5% lignans (SDG). Defat with food-grade ethanol → grind <80 mesh → ethanol extraction → SDG concentrate (10-30% purity). Sells to nutraceutical capsule market at 5-10× plain feed-cake price. Adds extractor + dryer + grinder (~$30-80k incremental capex).
