Oil extraction equipment for specialty oilseeds

Specialized oil extraction equipment designed for rare oilseeds—such as peony seeds, yellowhorn seeds, flaxseeds, perilla seeds, grape seeds, sea buckthorn seeds, pine nuts, and camellia seeds. It supports both cold and hot pressing modes, utilizes a physical pressing process without chemical solvents, and preserves the active nutrients of the oilseeds.

Specifications

Processing capacity :50–200 kg/h (varies by oilseed type)
Pressing mode :Dual-purpose (cold/hot pressing)
Temperature control :Adjustable from ambient to 80°C
Residual oil content in dry cake :≤7.5%
Main motor :5.5–15 kW
Materials in contact with product :SUS304 stainless steel + alloy press screw

Product Details

Specialized oil pressing equipment designed for rare oilseeds—such as peony seeds, yellowhorn seeds, flaxseeds, perilla seeds, grape seeds, sea buckthorn seeds, pine nuts, and camellia seeds. It supports both cold and hot pressing modes, utilizes a physical pressing process without chemical solvents, and preserves the active nutrients of the raw materials. It is ideal for specialty oil processing plants, organic oil workshops, and enterprises engaged in the deep processing of plant-based raw materials.

Advantages

Low-temperature cold pressing preserves nutrients; adjustable temperature control protects active substances like alpha-linolenic acid and phytosterols; can also switch to hot pressing to increase oil yield.

Material contact surfaces are made of 304 food-grade stainless steel; the pressing screw is made of wear-resistant alloy, ensuring hygiene and durability.

Customized pressing chamber ensures smooth feeding and prevents clogging; low residual oil content in the dry cake; cake residue can be recycled.

Smart digital control system allows for visual adjustment of temperature and pressure; simple operation; optional automatic feeding and oil filtration modules available.

Versatile machine; switch between oilseed varieties with simple parameter adjustments; modular structure facilitates easy disassembly, cleaning, and maintenance.

Working Principle

After pre-treatment, oilseeds are fed into the pressing chamber; the rotating screw compresses the material to extract the oil. Crude oil flows out through the press cage, while the pressed cake is discharged from the outlet. The system can be paired with an oil filter to remove impurities and connected to refining equipment as needed.

Optional Auxiliary Equipment

Cleaning machine, sheller, dryer, flaking machine, oil filter, small-scale refining unit, automatic feeder, oil storage tank.
