Optimizing Edible Oil Production with Advanced Deodorization and Refractionation

The edible oil industry is always seeking methods to refine products and improve operational efficiency. Two significant technologies contributing to refined edible oil production include the continuous deodorising plant and the refractionation plant. At Mectech, we understand these needs and offer engineering solutions designed to meet them.

Continuous Deodorising for Consistent Quality

Deodorization is a necessary step in refining edible oils. It removes undesirable volatile compounds that affect the oil's taste, smell, and stability. A continuous deodorising plant provides an efficient and consistent method for this process.

• Unlike batch processing, a continuous system processes oil in a steady flow, allowing for precise control over parameters like temperature, pressure, and steam injection. This is important for consistent product quality
• In a continuous deodorising plant, crude oil undergoes continuous heating and stripping. Under vacuum, steam is injected through the oil, carrying away volatile impurities.
• The continuous operation minimizes human intervention and reduces errors, leading to a uniform output. The design focuses on heat recovery, making the process energy-efficient and potentially lowering operating costs

The Advantage of a Dual Temperature Deodorizer

While a standard continuous deodorizer performs well, certain oils benefit from more specialized treatment. The dual temperature deodorizer is an advanced variation that provides increased flexibility and control.

• Staged Treatment: This system allows oil to be treated at two different temperature zones within the same unit.
• Targeted Impurity Removal: Some volatile compounds are removed at lower temperatures, while others require higher temperatures. A dual temperature deodorizer can address this by allowing for a staged removal of impurities.
• Improved Oil Characteristics: This method can result in oil with improved sensory characteristics and better oxidative stability. It also helps preserve beneficial compounds in the oil by removing certain impurities at lower temperatures.

Comprehensive Palm Olein Refining

Palm oil is a widely consumed edible oil, and its refining process is complex, involving several stages. A complete palm olein refinery handles all these steps, from crude palm oil (CPO) to a finished, refined product. At Mectech, our refinery designs integrate each stage to optimize output and quality

• Key Stages: A typical Palm Olein Refinery includes
1. Degumming: Removes phospholipids and other hydratable gums.
2. Bleaching: Removes color pigments and trace metals.
3. Deodorization: Removes volatile compounds, as discussed earlier.
• Product Goal: The goal is to produce clear, stable, and bland-tasting palm olein suitable for cooking and other food applications. Careful control of each step within a refinery system is important to achieve the desired quality characteristics

Precision Separation with a Refractionation Plant

After initial refining, palm oil is often separated into its liquid (olein) and solid (stearin) components. This process is called fractionation, and when performed with precision, it's referred to as refractionation. A refractionation plant further enhances the separation process.

• Controlled Crystallization: Refractionation plants use controlled cooling and crystallization processes. The oil is cooled at a specific rate to allow higher melting point triglycerides (stearin) to crystallize.
• Separation: These crystals are then separated from the liquid olein through filtration.
• Super Olein Production: Refractionation allows for the production of super olein, which has a lower cloud point and remains liquid even at cooler temperatures, making it suitable for colder climates or specific food applications.
