In the vegetable oil refining industry, production efficiency and oil quality remain two of the most important factors driving business performance. Traditional refining processes, particularly degumming and alkali neutralization, often involve significant oil losses, increased wastewater treatment requirements, and growing pressure to meet stricter food safety standards. With raw materials varying widely in type and quality, processors face an ongoing challenge: how can they reduce losses, improve product quality, and increase operational efficiency through technological innovation and equipment upgrades?

As a leading Chinese manufacturer of grain and oil processing equipment with 23 years of industry experience, Myande Group draws on extensive technical expertise and engineering experience worldwide to deliver efficient, intelligent, and environmentally responsible solutions.

Its R&D capabilities and contributions to the industry have recently received further national recognition. The Key Laboratory of Intelligent Equipment for Deep Processing of Grain and Oil, under China's Ministry of Agriculture and Rural Affairs, jointly established by Myande and Yangzhou University, has officially been approved. This national-level research platform reinforces Myande's position in intelligent grain and oil processing equipment and reflects its continued commitment to advancing the industry through intelligent manufacturing and higher-value processing.

Building on this technical foundation, Myande has developed two patented technologies: the Nano Cavitation Reaction System and the Dual Zero, Dual Low Deodorization System. Both technologies address longstanding challenges in oil refining and have demonstrated measurable improvements in industrial applications.

Key Technology 1: Nano Cavitation Reaction System

Reducing refining losses and increasing oil yield

Conventional acid and alkali refining processes often result in high oil losses, excessive by-product generation, and substantial wastewater treatment requirements. Myande's independently developed Nano Cavitation Reaction System addresses these challenges by optimizing reaction conditions under controlled physical environments, significantly improving the contact and reaction efficiency between oil, acid, and alkali.

Industrial application data show that the system can reduce acid consumption by up to 60%. More efficient and complete reactions also reduce the formation of soapstock and other refining by-products, allowing more oil to be retained in the finished product.

The result is higher refining yield, lower material consumption, and reduced wastewater treatment loads, helping processors recover more oil while improving overall production economics.

Key Technology 2: Dual Zero, Dual Low Deodorization System

Protecting oil quality through precise process control

High temperatures and prolonged heating during deodorization are major factors contributing to the formation of undesirable contaminants, including trans fatty acids (TFAs), glycidyl esters (GEs), and 3-monochloropropane-1,2-diol esters (3-MCPDE).

Myande's Dual Zero, Dual Low Deodorization System minimizes these risks through precise thermal management and optimized process conditions. The deodorization heater residence time is controlled to within 30 seconds, while a high-vacuum environment of 0.5 to 1.5 mbar enables efficient deacidification and deodorization at lower temperatures and with shorter heat exposure.

These measures significantly reduce the conditions that promote the formation of heat-induced contaminants.

The results are equally impressive. Glycidyl ester (GE) levels in deodorized oil are consistently reduced by more than 0.3 mg/kg, while other critical safety indicators, including 3-MCPDE, meet or outperform the latest EU standards. The system has also achieved zero trans fatty acids in multiple vegetable oil applications.

Beyond improving food safety, the technology helps preserve the natural flavor and stability of refined oils while enabling producers to meet increasingly stringent quality and regulatory requirements in both domestic and international markets.

From Higher Oil Yield to Better Oil Quality

From reducing refining losses and resource consumption to improving food safety and nutritional quality, Myande's technologies provide processors with practical, measurable benefits throughout the refining process.

For vegetable oil producers looking to upgrade their refining operations, Myande offers proven engineering solutions backed by extensive industrial experience and installations worldwide. More than equipment upgrades, these technologies provide a pathway towards more efficient, sustainable, and intelligent refining operations, supporting the development of next-generation digital and smart factories.
