Deodorization Tower

How the Deodorization Tower Works

The oil deodorization process uses the principle that the volatility of residual solvents, water and triglycerides in oils and fats is significantly different. Steam distillation is carried out under high temperature and high vacuum conditions to effectively remove residual solvents and water, so that the oils and fats are refined to meet strict quality standards.

Main Structure of Deodorization Tower

The deodorizing tower features a sophisticated design. Its main body comprises a cylindrical shell, an upper-layer high-temperature heater, a double-layer circulating oil tank, and an internally positioned packing layer of precise height. Four high-performance high-temperature heaters are strategically installed at the top of the main tower. These heaters utilize superheated steam to rapidly and uniformly heat the incoming oil.

The middle section of the tower is equipped with structured packing, enabling thin-film deodorization of the heated oil. A liquid distribution tray is installed above the packing layer, ensuring that the high-temperature oil is evenly distributed across the packing. This facilitates maximum contact with the direct steam, effectively removing solvents and drying the oil.

At the lower part of the tower, two layers of annular oil tank partitions are incorporated. Each partition is divided into four separate compartments, each fitted with an independent oil circulation system. This design ensures a controlled and optimized oil flow path. Mammoth pumps are installed in each compartment, through which direct steam is forcefully injected into the oil, creating a vigorous agitation and promoting efficient circulation. During operation, the direct steam, along with the extracted low  boiling substances, passes through the packing layer and is evacuated into the vacuum system, completing the deodorization process with precision and efficiency.
