 Vegetable oil refining machine

Seeds or fruits of plants, oils that have been preliminarily prepared by squeezing or extracting methods, are collectively referred to as scouring oil and must be refined before they can be eaten. The method of purifying different vegetable oils is not the same, and the refining machines used are not the same. It usually takes a few steps

Distillation, Evaporation of the solvent introduced during the extraction by evaporation.

Degumming, let the hot water (80°C) rinse the grease and stir it to stand to precipitate the gum and protein.

Neutralize, or deoxygenate, treat the oil with sodium hydroxide or sodium carbonate to remove free fatty acids, phospholipids, pigments, and waxes.

Bleach, remove unpleasant colors, use diatomaceous earth, activated carbon, activated soil to remove bad color.

Dewaxing, or freezing, improves the transparency of the oil, lowers the temperature, and removes precipitated solids.

For deodorization, volatile compounds that may cause abnormal odors and mouthfeel are evaporated by high-temperature, high-pressure steam.

Anti-corrosion, add preservatives to keep oils stable.

In addition, filtering such a non-chemical process that filters out large particles of impurities can also be considered a step of refining, although it does not change the state of the oil.
