Our products are known for their superior performance and reliability, making them a preferred choice across various industries. Here, we explore the diverse applications of the 3 Phase Disc Stack Separator in different sectors.



Applications of 3 Phase Disc Stack Separator

Animal and Vegetable Oil Separation

The 3 Phase Disc Stack Separator plays a crucial role in the separation of animal and vegetable oils. Vegetable oils such as rapeseed oil, cottonseed oil, corn oil, palm oil, soybean oil, peanut oil, sunflower oil, rice bran oil, sesame oil, and safflower oil can be efficiently separated. Similarly, animal oils including fish oil and various animal fats can be purified effectively.

Beverage Industry

In the beverage industry, our separators are indispensable for the purification and separation processes. They are used in the dairy industry for separating milk and cream, and in the production of fruit juices (like orange juice and apple juice), vegetable juices, tea drinks, coffee, and beer. The separators ensure high-quality, clarified products, enhancing the overall production process.

Pharmaceutical Industry

The pharmaceutical industry benefits greatly from our 3 Phase Disc Stack Separators. They are used for the separation of various extracts such as penicillin, vitamins, E. coli, antibiotics, and hormones. Additionally, they are essential for the concentration of microorganisms, the clarification of fermentation broth, and the separation of blood, ensuring purity and quality in pharmaceutical products.

Plant Extraction and Separation

Our separators are also extensively used in plant extraction and separation processes. They are effective in extracting pigments, peppers, tea leaves, loquat leaves, honeysuckle, ginkgo biloba, salvia, amygdalin, and traditional Chinese medicine extracts. This ensures the purity and quality of plant-based products, making them suitable for various applications.

Chemical Industry Separation

In the chemical industry, GN's 3 Phase Disc Stack Separators are used for separating lubricant additives, viscose, PVC, cellulose and its derivatives, ink and dye, phosphoric acid, herbicide, synthetic latex, boiler ash, and catalysts. They ensure efficient and thorough separation, improving the quality and usability of chemical products.

Fuel and Marine Oil Industry

Our separators are vital in the fuel and marine oil industry. They are used for the separation of methyl ester, glycerin, catalyst, soap removal, methanol, and water washing methyl ester. Additionally, they help in the extraction of fatty acids and glycerin desalination in the bio-oil sector. They also play a key role in the recovery and clarification of marine oil, and the removal of moisture and mechanical impurities in fuel oil (light diesel, heavy diesel, fuel oil) and lubricating oil of marine diesel engine equipment.

Environmental Protection Industry

In the environmental protection industry, our separators are used for food waste treatment and water treatment. They ensure efficient separation and purification, contributing to environmental sustainability and protection.
