Deodorization Tank

Deodorization Tank Function and Working Method

The Deodorization Tank operates by heating the oil using a combination of steam and thermal oil. The heat is applied to raise the temperature of the oil to between 245 - 265℃ , which is the optimal range for the removal of volatile compounds responsible for undesirable odors and FFA. The heated oil is then subjected to a vacuum environment, which helps to lower the boiling point of these volatile compounds, allowing them to be more easily evaporated and removed from the oil. The vacuum system continuously draws off the vaporized compounds, ensuring efficient deodorization and FFA reduction.

Deodorization Tank Material and Construction

Constructed from 0Cr18Ni9 stainless steel, the Deodorization Tank combines excellent corrosion resistance with high - temperature strength. This material choice ensures that the tank can withstand the rigorous conditions of continuous operation, including exposure to high - temperature oil and steam. The stainless steel construction also prevents contamination of the oil, maintaining its purity and quality throughout the deodorization process.

Deodorization Tank Key Features

• Working Method: The tank uses steam and thermal oil to heat the oil and a vacuum system to discharge odorous ingredients and FFA, ensuring efficient removal of impurities.

• Material: Made from 0Cr18Ni9 stainless steel, ensuring corrosion resistance and suitability for food - grade applications.

• Media: Designed to process vegetable oils and uses steam and thermal oil as heating media.

• Design Pressure: Operates at a vacuum pressure of -0.1 MPa, creating the necessary conditions for efficient deodorization.

• Working Temperature: The oil is heated to a working temperature of 245 - 265℃ , optimizing the removal of odors and FFA.

• Equipment Size: The size of the tank is determined based on the required production capacity, ensuring efficient and scalable operation.

• Production Standard: Manufactured in compliance with GB150-1998 《Steel Pressure Vessels》, ensuring the equipment meets stringent safety and quality standards.

Deodorization Tank Performance Advantages

• Efficient Deodorization: The combination of steam and thermal oil heating, along with vacuum treatment, ensures thorough removal of odors and FFA from the oil, improving its quality and stability.

• Durable Construction: The 0Cr18Ni9 stainless steel material ensures long - term reliability and resistance to corrosion and high - temperature conditions.

• Stable Operation: The tank is designed for stable and continuous operation, with precise control of temperature and pressure parameters.

• Energy - Efficient Heating: The use of steam and thermal oil ensures efficient heat transfer, minimizing energy consumption while maintaining optimal deodorization conditions.

• Food - Grade Safety: The stainless steel construction and compliance with pressure vessel standards ensure the equipment is suitable for food - grade applications, meeting hygiene and safety requirements.

Deodorization Tank Applications

The Deodorization Tank is widely used in vegetable oil processing plants, particularly in the production of refined palm oil, soybean oil, sunflower oil, and other edible oils. It is typically installed after the degumming, neutralization, and bleaching stages and before the final filtering and finishing processes. By removing odors and FFA, the Deodorization Tank helps to produce high - quality vegetable oils with improved flavor, color, and shelf - life. Its design and specifications make it suitable for integration into both new and existing vegetable oil processing facilities, enhancing their overall efficiency and product quality.
