How Vacuum Vegetable Oil Refinery Works?

Small and large vegetable oil refineries use vacuum technology to process oils efficiently in large volumes. It is important to have an understanding of how vacuum distillation separates different compounds in oil and how it helps keep the oil pure. Here are the steps and fundamentals of how vacuum vegetable oil refineries work.

1. The Basics of Vacuum Distillation.

Vacuum distillation is a process of separating substances and compounds that have boiling points significantly different from each other. The process is done under low pressure, which reduces the boiling point allowing for separation of the compounds. It is a process based on thermodynamics principles where high-pressure and high-temperature compounds are separated by reducing boiling points.

2. The Process of Vacuum Vegetable Oil Refining.

The process of refining vegetable oil can be broken down into several stages such as degumming, neutralization, bleaching, and deodorization. Each stage prepares the oil for the next step, and the vacuum is present in the last two stages of the refining process.

- Deodorization.

Deodorization is the stage where the volatile flavor compounds and odorants are removed from the oil. The process is done in a vacuum where the oil is heated to high temperatures to evaporate the volatile compounds. The vacuum applied helps keep the oil pure and prevents oxidation due to high-temperature cooking. The removal of volatile compounds improves the stability and shelf life of the oil.

- Bleaching.

Bleaching is the process of removing pigments and other unwanted compounds from the oil. The process involves the use of activated earth or charcoal. The vacuum applied during the bleaching process ensures the purity of the oil, as the equipment is designed to remove contaminating agents.

3. Special Considerations.

Special considerations are given to the quality of the oil produced in vacuum vegetable refineries. Here are some of the aspects considered during the refining process.

- Refined Oils Quality Standards.

Refined oil must meet specific quality standards since it is designed for human consumption. The vegetable oil industry has various governing bodies that set quality standards for the oil. These standards are established based on chemical composition, flavor, and color.

- Use of Additives.

Additives such as citric acid can be used in the refining process to help preserve the oil and prevent it from becoming rancid. The use of additives has to be approved and regulated by the authorities, to ensure that the oil remains safe for consumption.

4. Advantages of Vacuum Vegetable Oil Refinery.

Vacuum Vegetable Oil Refinery has several advantages that make it an ideal way to refine vegetable oil, including:

- High-Quality Oil.

Vacuum technology ensures that the oil remains pure and does not get contaminated. The process helps produce high-quality oil that meets set standards.

- Efficiency.

Vacuum technology allows for faster processing of vegetable oil compared to traditional refining processes. It reduces the processing times without compromising the quality of the oil.

- Versatility.

Vacuum vegetable oil refinery is a versatile refining process that can handle a wide range of oils, including soybean oil, sunflower oil, palm oil, and rapeseed oil.

Conclusion.

Vacuum vegetable oil refinery is a modern and efficient method of refining vegetable oil to high-quality standards. The vacuum technology ensures that the oil is pure and free of contaminants and that the process is efficient, economical, and environmentally friendly. As the demand for healthy and high-quality vegetable oil increases, vacuum vegetable oil refineries will continue to play a crucial role in the industry.
