This oil Refining plant produces edible oil with characteristics that consumers desire such as bland flavor and odor, clear appearance, light color, stability to oxidation and suitability for frying pressing rapeseed oil, cottonseed oil, soybean oil, peanut oil, linseed oil, sunflower oil and other vegetable oils.
The classical alkaline refining method usually comprises the following steps:
Step 1. Degumming with water to remove the easily hydratable phospholipids and metals.
Step 2. Addition of a small amount of phosphoric or citric acid to convert the remaining non-hydralable phospholipids (Ca, Mg salts) into hydratable phospholipids.
Step 3. Neutralizing of the free fatty acids with a slight excess of sodium hydroxide solution, followed by the washing out of soaps and hydrated phospholipids.
Step 4. Bleaching with natural or acid-activated clay minerals to adsorb coloring components and to decompose hydro peroxides.
Step 5. Deodorizing to remove volatile components, mainly aldehydes and ketones, with low threshold values for detection by taste or smell. Deodorization is essentially a steam distillation process carried out at low pressures (2-6 mbar) and elevated temperatures (180-220°C)
The equipment has peculiar characteristics:–
– Simple structure
– Easy operation
– High oil yield
– Low noise
