Oilseeds Cold Press Pretreatment Equipment

Oilseeds Cold Press Machine

Cold press is suitable for high added-value oilseeds. Such as grape seed, camellia seed, walnut, almond, flaxseed, etc. Cold press has advantages of low oil temperature when pressing, light color, abundant nutrients, small protein damage, saving steam, high protein content in cake.

Cold pressing oil production process

Oilseeds→cleaning→separation of shells and kernels→seed kernels→low temperature drying→reduce removal→conditioning-cold pressing→fine filtration and cold-pressed finished oil.

Processing Capacity: 10-500T/D

Suitable oilseeds :Rapeseed, Camellia seed, Walnut kernel, Almond, Rubber seed, Sesame, Flaxseed.

Cold Pressing Technology

Cold pressing is the simple and traditional method of producing oil. The seed is simply pressed (or squeezed) at a low temperature, which means that the oils natural rich golden colour and nutrients are preserved. Once the oil has settled, it is filtered and then bottled. It really is as simple as that. No heat, no chemicals just pure and healthy homegrown oil. We only press our seed once, this ensures that we only produce the highest quality, undiluted cold pressed rapeseed oil.

Cold pressing is a manufacturing process that produces oil. The cold pressing method generally requires processing in an environment below 60°C to retain the most complete nutrients. Cold pressing oil production technology is a kind of production that directly presses the oil that has not been rolled or steamed between room temperature and 65 degrees Celsius through a low-temperature oil press to obtain oil and cake whose nutritional value and molecular structure have not changed. oil technology.

Cold pressing oil production process and its characteristics

The cold-pressed oil production method is a physical method that pressurizes the oil without raising the temperature and has no effect on the nutrients of the oil. At the same time, in addition to the general characteristics of ordinary oil-making processes, this process can also improve the quality of oil, avoid the production of harmful substances such as trans fatty acids and oil polymers due to high-temperature processing, and retain the active substances in the oil.

Working Principle

01

Cleaning & destoning

Vibrating screen, magnet and destoner remove impurities, stones and metal to >99% purity.

02

Crushing

Roller crusher breaks seeds to uniform size for even flaking.

03

Softening

Conditioning cylinder warms and softens kernels to the right plasticity.

04

Flaking

Flaking rolls form thin, uniform flakes to shorten the oil pathway.

05

Cooking / conditioning

Stacked cooker adjusts moisture and temperature to the optimal pre-extraction state.

06

Extruding / pre-pressing

Extruder gelatinizes flakes (for extraction) or pre-press recovers part of the oil from high-oil seeds.
