What Does The Small Rice Bran Oil Refinery Include?

The main equipment used in rice bran oil refinery:

¡¡ (1). Refining pot: used to P-acid de-gumming, alkali refining de-acid and water rinsing.

¡¡¡¡(2).De-color pot: used to remove off pigments, bleaching oils and grease de-hydrate.

¡¡¡¡(3).De-odor pot: used to remove off oils odor, foreign smells (stainless made) Heat transfer oil stove: supply each device production needing heat energy, temperature reach above 280°C.

¡¡¡¡(4).Steam generator: produce the needing steam for de-odoring and distillation.

¡¡¡¡(5).Vacuum pump: supply needing vacuum for dehydrate, de-color, de-odor. Vacuum degree can reach above 755mmHg.

¡¡¡¡(6).Press filter: filter clay, filter out clear oil.

¡¡¡¡(7).Air compressor: blow dry bleached clay, blow empty the leftover oil in

¡¡¡¡What is the function of small rice bran oil refinery of Each Part?

¡¡¡¡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.Neutralising 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 hydroperoxides.

Step 5.Deodorising to remove volatile components, mainly aldehydes and ketones, with low threshold values for detection by taste or smell. Deodorisation is essentially a steam distillation process carried out at low pressures (2-6 mbar) and elevated temperatures (180-220°C).
