The Vertical Leaf Filter is a high-efficiency pressure filtration equipment widely used in edible oil refining plants. It is mainly applied in the bleaching and dewaxing sections for removing clay, pigments, and solid impurities from the oil. This filter adopts a vertical structure with multiple filter leaves installed inside the tank, enabling continuous and efficient separation under pressure. The design ensures easy discharge, low oil loss, and safe, clean operation.

Voson’s vertical leaf filters are made of high-quality stainless steel and manufactured through precision welding and laser cutting, ensuring excellent sealing, corrosion resistance, and long service life. The closed operation mode prevents oil oxidation and environmental pollution, meeting modern edible oil processing requirements.

Application in Oil Refining Process

In the edible oil refining plant, the vertical leaf filter is typically used after the bleaching section to remove spent bleaching earth and impurities from the decolorized oil. It is also used in the winterization (dewaxing) process to separate crystallized waxes from the oil. This equipment is applicable to a wide range of oils, including soybean oil, sunflower oil, palm oil, peanut oil, and corn oil. Its closed and efficient filtration ensures clear, bright oil and stable product quality.
