Rice bran oil pressing is a common edible oil production process. The following are simple rice bran oil pressing process steps:
Cleaning: The rice bran is cleaned to remove impurities and unwanted particles.
Drying: Dry the cleaned rice bran to reduce the water content. The general drying temperature is 60-80 degrees Celsius.

Steam: put the broken rice bran into a steamer for steaming, the cooking temperature is generally about 100 degrees Celsius, and the cooking time is 20-30 minutes.
Oil Pressing: The steamed rice bran is put into an oil press for oil extraction. The oil press machine separates the oil from the rice bran by mechanical pressing to obtain rice bran oil and oil residue.
Filtration: Filter the turbid liquid obtained from oil extraction to remove impurities and sediments to obtain clear rice bran oil.
Refining: Refining the dehydrated rice bran oil to remove impurities, acidic substances and odors, and improve the purity and taste of the oil.
