Flaxseed Oil Pressing Line

Flaxseed is a small seed, and the crushed material and expressed oil require controlled handling to limit oxidation. Cold-pressed and heat-conditioned flaxseed oils are different product specifications and should be trialed and quoted separately.

Raw Material Boundary

Identify seed variety, origin, moisture, impurities, damaged or moldy seed, storage time, and intended food or industrial use. Remove dust, stones, metal, and rancid lots. Quote capacity on cleaned dry seed and record cleaning loss separately.

Recommended Pretreatment

1. Screen and aspirate small foreign material.
2. Remove stones and metal.
3. Measure moisture and dry gently only when required.
4. Crush to a repeatable size shortly before pressing.
5. Limit waiting time between crushing, pressing, filtration, and tank closure.

Pressing Route and Equipment

For specialty cold-pressed oil, use a low-temperature hydraulic batch trial with rapid handling of crushed seed. A warm or hot-conditioned route may improve pressing behavior but creates a different flavor and oxidation profile and must be evaluated on the same lot. For continuous commercial volume, compare a screw-press route and downstream solids handling.

Equipment Entry Points

• Pretreatment equipment
• High-speed pulverizer
• Hydraulic oil press range
• 480 Series hydraulic oil press as an existing model entry for trial sizing
• Pneumatic filter press
• Filling equipment

Filtration and Finished-Oil Target

Define settled or fine-filtered oil, visible sediment, clarity, color, aroma, oxidation test method, and sampling time. Closed tanks and light-protective packaging should be specified where required, together with the maximum permitted delay between pressing and final closure.

Data Required for a Quotation

• Representative cleaned-seed sample, variety, moisture, impurities, storage time, and oxidation condition
• Dry-seed input per batch or day, operating hours, and batch or continuous duty
• Cold-pressed or heat-conditioned product target and oil-temperature recording requirement
• Settling, filtration, tank, package, sampling, and oxidation-test scope
• Power, heat if used, floor space, destination, and delivery terms

Acceptance Records

Record cleaning loss, seed moisture, crush size, conditioning settings where used, charge or feed rate, cycle time, oil temperature, crude and filtered oil, and cake. Note the elapsed time from crushing to pressing and from pressing to closed storage. Compare clarity, color, aroma, and agreed oxidation results only for the documented lot and route.
