Edible Oil Deodorizer

In the fats and oils refining industry, deodorization is the critical final stage that determines the quality, shelf-life, and safety of the final product. The SEPARATECH edible oil deodorizer is engineered to effectively remove free fatty acids (FFA), volatile odor compounds, aldehydes, and ketones from crude vegetable oils.

Innovative edible oil deodorizer design from SEPARATECH, a firm that cooperated with specialized team in designing and manufacturing high-quality deodorization systems for various types of oils and fats. Ultra-high efficiency in deodorization process in oil refining.

By combining continuous oil deodorization tower designs with precise temperature and high-vacuum control, our systems guarantee excellent physical refining results, preserving valuable natural tocopherols while minimizing unwanted sub-products.

Edible Oil Deodorizer

Engineered for High-FFA Physical Refining Challenges

The edible oil deodorizer design from SEPARATECH is special designed for removing the volatile compounds, flavors, hydroperoxides, and some contaminants in the oil, in a process that takes place at 180°C–240°C. It is a process correlated with the reduction of FFA in the oil. These unwanted substances negatively affect the odor, flavor, color and stability of the final product . Deodorization is a steam-distillation process that takes place under vacuum and high temperature conditions.

Our fats and oils deodorization system excels in physical refining setups, particularly for high-FFA stocks like a palm oil deodorization plant. The multi-stage stripping tower for oil refining segregates the flashing, stripping, and deacidification phases, allowing rapid evaporation of fatty acids without overheating the bulk oil. Whether processing delicate sunflower seed oil or bulk crude palm oil, SEPARATECH customizes the tray-type or packed-bed internal layout to optimize your specific daily yield.

Main structure of edible oil deodorizer design

The main structure of the SEPARATECH edible oil deodorizer consists of a deaerator, an economizer, a final heater, a deodorization column and a condenser. The deaerator removes air from the oil under vacuum to prevent oxidation. The economizer regeneratively heats the oil by using the hot oil leaving the deodorization column. The final heater brings the oil to the exact temperature required for deodorization, normally using high-pressure steam. The deodorization column is where the actual stripping of free fatty acids and volatile components takes place. The column can have a stripping section and a retention section, depending on the type of oil and the desired quality . The condenser cools down and recovers the vapours leaving the column.

Working principle

The working principle of the edible oil deodorizer designed based on the difference in volatility between the oil and the unwanted substances. When steam is passed through the oil at high temperature and low pressure, the free fatty acids and volatile components are evaporated and carried away by the steam. The oil is then discharged from the bottom of the column as a refined product.

Features and advantages

  • High-Efficiency FFA Stripping: Optimizes the removal of free fatty acids and volatile components, ensuring a low acid value and zero off-flavor in the finished oil.
  • Advanced Packed Bed Deodorizer Structure: Utilizes premium structured packing to provide a large surface area for steam stripping, significantly reducing oil retention time and preventing thermal degradation.
  • Minimal Trans-Fatty Acids & Contaminants: Precise control of stripping steam and thermal retention limits the formation of Trans-Fatty Acids (TFA), 3-MCPD, and Glycidyl Esters (GE) to meet strict international food safety standards.
  • Maximum Thermal Energy Recovery: Integrated with multi-stage heat exchangers and a cold-oil/hot-oil economizer system, recovering up to 80% of heat process energy to lower factory running costs.
  • Superior Vacuum Stability: Equipped with reliable steam jet ejectors and vacuum systems to maintain absolute pressures below 2-3 mbar throughout continuous operation.
  • Edible oil deodorizer uses less steam and operates at lower temperatures than conventional deodorizers, resulting in more gentle and effective treatment that greatly benefits the quality of the fats and oils.
  • Edible oil deodorizer is extremely versatile and can handle different types of oils, such as palm, soybean, rapeseed or other edible oils, with different processing requirements .
  • Edible oil deodorizer has a smart instrumentation and control system that makes it easy to operate and monitor .
  • Edible oil deodorizer has a patented thin-film technology that enhances the stripping and retention efficiency of the column .
  • Edible oil deodorizer reduces product loss and utility consumption by optimizing heat recovery and minimizing residence time .
  • Edible oil deodorizer improves GE removal to levels below 0.5 ppm and reduces TFA isomers formation .
