In edible oil refining, temperature is the most critical control variable — and the most underestimated source of energy consumption.

Different oil types and different process stages have completely different temperature sensitivities. Unstable or excessively high temperatures not only cause significant loss of nutrients such as vitamin E and sterols but also promote the formation of glycidyl esters (GE) and trans fatty acids (TFA) — the very indicators subject to the strictest limits when exporting to high-end markets like the EU.

Ocean's solution: match the most appropriate process temperature curve to each oil type, while minimizing energy consumption through heat exchange technology.

Oil-to-Oil Heat Exchange: A Proven Energy-Saving Technology

Ocean fully utilizes "oil-to-oil heat exchange" technology across the four core stages — degumming, deacidification, bleaching, and deodorization — exchanging heat between refined high-temperature oil and unrefined low-temperature oil. This technology has helped numerous oil enterprises save over 65% in energy consumption.

The self-developed energy-saving heat exchanger offers high heat exchange efficiency, perfectly replaces traditional post-stripping equipment, occupies less floor space, and reduces civil construction investment costs.

Ocean's Technical Targets

· Maximize retention of vitamin E and sterols in oils

· Control GE content ≤50 mg/kg and 3-MCPD content ≤2 μg/kg (EU standards)

· Reduce auxiliary material consumption and contact between auxiliaries and oil

· Improve oxidative stability of finished oils, control TFA increase and color reversion

· Increase refining yield

With 20+ years of hands-on experience and over 200 oil refining projects worldwide, Ocean precisely controls temperature specifications at each step, avoids potential risks in engineering, and ensures stable production and high-standard oil quality.

Ocean, focused on oil refining for over two decades, is a global leading turnkey oils & fats processing solutions provider , bringing safe and healthy edible oil to every household.
