The main working principle of oil refining equipment
The working principle of Cooking Oil Refinery Plant mainly includes the following key steps:
1) Degumming: By adding hot water or acidic substances, the phospholipids and other colloid-soluble impurities in the oil are precipitated and removed.
2) Deacidification: Using the alkali refining method, alkali solution is added to neutralize the free fatty acids to generate soap beans and then separate them.
3) Decolorization: Use adsorbents such as activated carbon or white clay to remove pigments in oils and make the oils clear and transparent.
4) Deodorization: Remove odor substances in oils and oils through high-temperature steam distillation to enhance the flavor of oils and oils.
Changes in oil after refining
1. Appearance and smell:
Color: Crude oil is usually darker in color, may contain impurities and turbidity; refined oil becomes clear and transparent, light yellow or colorless.
Smell: Crude oil may have a peculiar smell, while refined oil is deodorized and has a purer smell, making it suitable for consumption.
2. Ingredients:
Impurity removal: Impurities such as water, phospholipids, free fatty acids, pigments, heavy metals, etc. contained in crude oil are removed during the refining process.
Changes in nutritional ingredients: Some natural antioxidant ingredients (such as vitamin E) may be reduced during the refining process, but the stability of the oil is significantly improved.
3. Performance:
Improved smoke point: Refined oil has a higher smoke point, which is suitable for high-temperature cooking (such as frying, deep-frying, and stir-frying) and reduces the generation of oil smoke.
Enhanced stability: Refined oil has stronger antioxidant and chemical stability, and is more suitable for long-term storage and deep processing.
